++ GNU LESSER GENERAL PUBLIC LICENSE
++ Version 2.1, February 1999
++
++ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
++ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
++ Everyone is permitted to copy and distribute verbatim copies
++ of this license document, but changing it is not allowed.
++
++[This is the first released version of the Lesser GPL. It also counts
++ as the successor of the GNU Library Public License, version 2, hence
++ the version number 2.1.]
++
++ Preamble
++
++ The licenses for most software are designed to take away your
++freedom to share and change it. By contrast, the GNU General Public
++Licenses are intended to guarantee your freedom to share and change
++free software--to make sure the software is free for all its users.
++
++ This license, the Lesser General Public License, applies to some
++specially designated software packages--typically libraries--of the
++Free Software Foundation and other authors who decide to use it. You
++can use it too, but we suggest you first think carefully about whether
++this license or the ordinary General Public License is the better
++strategy to use in any particular case, based on the explanations below.
++
++ When we speak of free software, we are referring to freedom of use,
++not price. Our General Public Licenses are designed to make sure that
++you have the freedom to distribute copies of free software (and charge
++for this service if you wish); that you receive source code or can get
++it if you want it; that you can change the software and use pieces of
++it in new free programs; and that you are informed that you can do
++these things.
++
++ To protect your rights, we need to make restrictions that forbid
++distributors to deny you these rights or to ask you to surrender these
++rights. These restrictions translate to certain responsibilities for
++you if you distribute copies of the library or if you modify it.
++
++ For example, if you distribute copies of the library, whether gratis
++or for a fee, you must give the recipients all the rights that we gave
++you. You must make sure that they, too, receive or can get the source
++code. If you link other code with the library, you must provide
++complete object files to the recipients, so that they can relink them
++with the library after making changes to the library and recompiling
++it. And you must show them these terms so they know their rights.
++
++ We protect your rights with a two-step method: (1) we copyright the
++library, and (2) we offer you this license, which gives you legal
++permission to copy, distribute and/or modify the library.
++
++ To protect each distributor, we want to make it very clear that
++there is no warranty for the free library. Also, if the library is
++modified by someone else and passed on, the recipients should know
++that what they have is not the original version, so that the original
++author's reputation will not be affected by problems that might be
++introduced by others.
++
++ Finally, software patents pose a constant threat to the existence of
++any free program. We wish to make sure that a company cannot
++effectively restrict the users of a free program by obtaining a
++restrictive license from a patent holder. Therefore, we insist that
++any patent license obtained for a version of the library must be
++consistent with the full freedom of use specified in this license.
++
++ Most GNU software, including some libraries, is covered by the
++ordinary GNU General Public License. This license, the GNU Lesser
++General Public License, applies to certain designated libraries, and
++is quite different from the ordinary General Public License. We use
++this license for certain libraries in order to permit linking those
++libraries into non-free programs.
++
++ When a program is linked with a library, whether statically or using
++a shared library, the combination of the two is legally speaking a
++combined work, a derivative of the original library. The ordinary
++General Public License therefore permits such linking only if the
++entire combination fits its criteria of freedom. The Lesser General
++Public License permits more lax criteria for linking other code with
++the library.
++
++ We call this license the "Lesser" General Public License because it
++does Less to protect the user's freedom than the ordinary General
++Public License. It also provides other free software developers Less
++of an advantage over competing non-free programs. These disadvantages
++are the reason we use the ordinary General Public License for many
++libraries. However, the Lesser license provides advantages in certain
++special circumstances.
++
++ For example, on rare occasions, there may be a special need to
++encourage the widest possible use of a certain library, so that it becomes
++a de-facto standard. To achieve this, non-free programs must be
++allowed to use the library. A more frequent case is that a free
++library does the same job as widely used non-free libraries. In this
++case, there is little to gain by limiting the free library to free
++software only, so we use the Lesser General Public License.
++
++ In other cases, permission to use a particular library in non-free
++programs enables a greater number of people to use a large body of
++free software. For example, permission to use the GNU C Library in
++non-free programs enables many more people to use the whole GNU
++operating system, as well as its variant, the GNU/Linux operating
++system.
++
++ Although the Lesser General Public License is Less protective of the
++users' freedom, it does ensure that the user of a program that is
++linked with the Library has the freedom and the wherewithal to run
++that program using a modified version of the Library.
++
++ The precise terms and conditions for copying, distribution and
++modification follow. Pay close attention to the difference between a
++"work based on the library" and a "work that uses the library". The
++former contains code derived from the library, whereas the latter must
++be combined with the library in order to run.
++
++ GNU LESSER GENERAL PUBLIC LICENSE
++ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
++
++ 0. This License Agreement applies to any software library or other
++program which contains a notice placed by the copyright holder or
++other authorized party saying it may be distributed under the terms of
++this Lesser General Public License (also called "this License").
++Each licensee is addressed as "you".
++
++ A "library" means a collection of software functions and/or data
++prepared so as to be conveniently linked with application programs
++(which use some of those functions and data) to form executables.
++
++ The "Library", below, refers to any such software library or work
++which has been distributed under these terms. A "work based on the
++Library" means either the Library or any derivative work under
++copyright law: that is to say, a work containing the Library or a
++portion of it, either verbatim or with modifications and/or translated
++straightforwardly into another language. (Hereinafter, translation is
++included without limitation in the term "modification".)
++
++ "Source code" for a work means the preferred form of the work for
++making modifications to it. For a library, complete source code means
++all the source code for all modules it contains, plus any associated
++interface definition files, plus the scripts used to control compilation
++and installation of the library.
++
++ Activities other than copying, distribution and modification are not
++covered by this License; they are outside its scope. The act of
++running a program using the Library is not restricted, and output from
++such a program is covered only if its contents constitute a work based
++on the Library (independent of the use of the Library in a tool for
++writing it). Whether that is true depends on what the Library does
++and what the program that uses the Library does.
++
++ 1. You may copy and distribute verbatim copies of the Library's
++complete source code as you receive it, in any medium, provided that
++you conspicuously and appropriately publish on each copy an
++appropriate copyright notice and disclaimer of warranty; keep intact
++all the notices that refer to this License and to the absence of any
++warranty; and distribute a copy of this License along with the
++Library.
++
++ You may charge a fee for the physical act of transferring a copy,
++and you may at your option offer warranty protection in exchange for a
++fee.
++
++ 2. You may modify your copy or copies of the Library or any portion
++of it, thus forming a work based on the Library, and copy and
++distribute such modifications or work under the terms of Section 1
++above, provided that you also meet all of these conditions:
++
++ a) The modified work must itself be a software library.
++
++ b) You must cause the files modified to carry prominent notices
++ stating that you changed the files and the date of any change.
++
++ c) You must cause the whole of the work to be licensed at no
++ charge to all third parties under the terms of this License.
++
++ d) If a facility in the modified Library refers to a function or a
++ table of data to be supplied by an application program that uses
++ the facility, other than as an argument passed when the facility
++ is invoked, then you must make a good faith effort to ensure that,
++ in the event an application does not supply such function or
++ table, the facility still operates, and performs whatever part of
++ its purpose remains meaningful.
++
++ (For example, a function in a library to compute square roots has
++ a purpose that is entirely well-defined independent of the
++ application. Therefore, Subsection 2d requires that any
++ application-supplied function or table used by this function must
++ be optional: if the application does not supply it, the square
++ root function must still compute square roots.)
++
++These requirements apply to the modified work as a whole. If
++identifiable sections of that work are not derived from the Library,
++and can be reasonably considered independent and separate works in
++themselves, then this License, and its terms, do not apply to those
++sections when you distribute them as separate works. But when you
++distribute the same sections as part of a whole which is a work based
++on the Library, the distribution of the whole must be on the terms of
++this License, whose permissions for other licensees extend to the
++entire whole, and thus to each and every part regardless of who wrote
++it.
++
++Thus, it is not the intent of this section to claim rights or contest
++your rights to work written entirely by you; rather, the intent is to
++exercise the right to control the distribution of derivative or
++collective works based on the Library.
++
++In addition, mere aggregation of another work not based on the Library
++with the Library (or with a work based on the Library) on a volume of
++a storage or distribution medium does not bring the other work under
++the scope of this License.
++
++ 3. You may opt to apply the terms of the ordinary GNU General Public
++License instead of this License to a given copy of the Library. To do
++this, you must alter all the notices that refer to this License, so
++that they refer to the ordinary GNU General Public License, version 2,
++instead of to this License. (If a newer version than version 2 of the
++ordinary GNU General Public License has appeared, then you can specify
++that version instead if you wish.) Do not make any other change in
++these notices.
++
++ Once this change is made in a given copy, it is irreversible for
++that copy, so the ordinary GNU General Public License applies to all
++subsequent copies and derivative works made from that copy.
++
++ This option is useful when you wish to copy part of the code of
++the Library into a program that is not a library.
++
++ 4. You may copy and distribute the Library (or a portion or
++derivative of it, under Section 2) in object code or executable form
++under the terms of Sections 1 and 2 above provided that you accompany
++it with the complete corresponding machine-readable source code, which
++must be distributed under the terms of Sections 1 and 2 above on a
++medium customarily used for software interchange.
++
++ If distribution of object code is made by offering access to copy
++from a designated place, then offering equivalent access to copy the
++source code from the same place satisfies the requirement to
++distribute the source code, even though third parties are not
++compelled to copy the source along with the object code.
++
++ 5. A program that contains no derivative of any portion of the
++Library, but is designed to work with the Library by being compiled or
++linked with it, is called a "work that uses the Library". Such a
++work, in isolation, is not a derivative work of the Library, and
++therefore falls outside the scope of this License.
++
++ However, linking a "work that uses the Library" with the Library
++creates an executable that is a derivative of the Library (because it
++contains portions of the Library), rather than a "work that uses the
++library". The executable is therefore covered by this License.
++Section 6 states terms for distribution of such executables.
++
++ When a "work that uses the Library" uses material from a header file
++that is part of the Library, the object code for the work may be a
++derivative work of the Library even though the source code is not.
++Whether this is true is especially significant if the work can be
++linked without the Library, or if the work is itself a library. The
++threshold for this to be true is not precisely defined by law.
++
++ If such an object file uses only numerical parameters, data
++structure layouts and accessors, and small macros and small inline
++functions (ten lines or less in length), then the use of the object
++file is unrestricted, regardless of whether it is legally a derivative
++work. (Executables containing this object code plus portions of the
++Library will still fall under Section 6.)
++
++ Otherwise, if the work is a derivative of the Library, you may
++distribute the object code for the work under the terms of Section 6.
++Any executables containing that work also fall under Section 6,
++whether or not they are linked directly with the Library itself.
++
++ 6. As an exception to the Sections above, you may also combine or
++link a "work that uses the Library" with the Library to produce a
++work containing portions of the Library, and distribute that work
++under terms of your choice, provided that the terms permit
++modification of the work for the customer's own use and reverse
++engineering for debugging such modifications.
++
++ You must give prominent notice with each copy of the work that the
++Library is used in it and that the Library and its use are covered by
++this License. You must supply a copy of this License. If the work
++during execution displays copyright notices, you must include the
++copyright notice for the Library among them, as well as a reference
++directing the user to the copy of this License. Also, you must do one
++of these things:
++
++ a) Accompany the work with the complete corresponding
++ machine-readable source code for the Library including whatever
++ changes were used in the work (which must be distributed under
++ Sections 1 and 2 above); and, if the work is an executable linked
++ with the Library, with the complete machine-readable "work that
++ uses the Library", as object code and/or source code, so that the
++ user can modify the Library and then relink to produce a modified
++ executable containing the modified Library. (It is understood
++ that the user who changes the contents of definitions files in the
++ Library will not necessarily be able to recompile the application
++ to use the modified definitions.)
++
++ b) Use a suitable shared library mechanism for linking with the
++ Library. A suitable mechanism is one that (1) uses at run time a
++ copy of the library already present on the user's computer system,
++ rather than copying library functions into the executable, and (2)
++ will operate properly with a modified version of the library, if
++ the user installs one, as long as the modified version is
++ interface-compatible with the version that the work was made with.
++
++ c) Accompany the work with a written offer, valid for at
++ least three years, to give the same user the materials
++ specified in Subsection 6a, above, for a charge no more
++ than the cost of performing this distribution.
++
++ d) If distribution of the work is made by offering access to copy
++ from a designated place, offer equivalent access to copy the above
++ specified materials from the same place.
++
++ e) Verify that the user has already received a copy of these
++ materials or that you have already sent this user a copy.
++
++ For an executable, the required form of the "work that uses the
++Library" must include any data and utility programs needed for
++reproducing the executable from it. However, as a special exception,
++the materials to be distributed need not include anything that is
++normally distributed (in either source or binary form) with the major
++components (compiler, kernel, and so on) of the operating system on
++which the executable runs, unless that component itself accompanies
++the executable.
++
++ It may happen that this requirement contradicts the license
++restrictions of other proprietary libraries that do not normally
++accompany the operating system. Such a contradiction means you cannot
++use both them and the Library together in an executable that you
++distribute.
++
++ 7. You may place library facilities that are a work based on the
++Library side-by-side in a single library together with other library
++facilities not covered by this License, and distribute such a combined
++library, provided that the separate distribution of the work based on
++the Library and of the other library facilities is otherwise
++permitted, and provided that you do these two things:
++
++ a) Accompany the combined library with a copy of the same work
++ based on the Library, uncombined with any other library
++ facilities. This must be distributed under the terms of the
++ Sections above.
++
++ b) Give prominent notice with the combined library of the fact
++ that part of it is a work based on the Library, and explaining
++ where to find the accompanying uncombined form of the same work.
++
++ 8. You may not copy, modify, sublicense, link with, or distribute
++the Library except as expressly provided under this License. Any
++attempt otherwise to copy, modify, sublicense, link with, or
++distribute the Library is void, and will automatically terminate your
++rights under this License. However, parties who have received copies,
++or rights, from you under this License will not have their licenses
++terminated so long as such parties remain in full compliance.
++
++ 9. You are not required to accept this License, since you have not
++signed it. However, nothing else grants you permission to modify or
++distribute the Library or its derivative works. These actions are
++prohibited by law if you do not accept this License. Therefore, by
++modifying or distributing the Library (or any work based on the
++Library), you indicate your acceptance of this License to do so, and
++all its terms and conditions for copying, distributing or modifying
++the Library or works based on it.
++
++ 10. Each time you redistribute the Library (or any work based on the
++Library), the recipient automatically receives a license from the
++original licensor to copy, distribute, link with or modify the Library
++subject to these terms and conditions. You may not impose any further
++restrictions on the recipients' exercise of the rights granted herein.
++You are not responsible for enforcing compliance by third parties with
++this License.
++
++ 11. If, as a consequence of a court judgment or allegation of patent
++infringement or for any other reason (not limited to patent issues),
++conditions are imposed on you (whether by court order, agreement or
++otherwise) that contradict the conditions of this License, they do not
++excuse you from the conditions of this License. If you cannot
++distribute so as to satisfy simultaneously your obligations under this
++License and any other pertinent obligations, then as a consequence you
++may not distribute the Library at all. For example, if a patent
++license would not permit royalty-free redistribution of the Library by
++all those who receive copies directly or indirectly through you, then
++the only way you could satisfy both it and this License would be to
++refrain entirely from distribution of the Library.
++
++If any portion of this section is held invalid or unenforceable under any
++particular circumstance, the balance of the section is intended to apply,
++and the section as a whole is intended to apply in other circumstances.
++
++It is not the purpose of this section to induce you to infringe any
++patents or other property right claims or to contest validity of any
++such claims; this section has the sole purpose of protecting the
++integrity of the free software distribution system which is
++implemented by public license practices. Many people have made
++generous contributions to the wide range of software distributed
++through that system in reliance on consistent application of that
++system; it is up to the author/donor to decide if he or she is willing
++to distribute software through any other system and a licensee cannot
++impose that choice.
++
++This section is intended to make thoroughly clear what is believed to
++be a consequence of the rest of this License.
++
++ 12. If the distribution and/or use of the Library is restricted in
++certain countries either by patents or by copyrighted interfaces, the
++original copyright holder who places the Library under this License may add
++an explicit geographical distribution limitation excluding those countries,
++so that distribution is permitted only in or among countries not thus
++excluded. In such case, this License incorporates the limitation as if
++written in the body of this License.
++
++ 13. The Free Software Foundation may publish revised and/or new
++versions of the Lesser General Public License from time to time.
++Such new versions will be similar in spirit to the present version,
++but may differ in detail to address new problems or concerns.
++
++Each version is given a distinguishing version number. If the Library
++specifies a version number of this License which applies to it and
++"any later version", you have the option of following the terms and
++conditions either of that version or of any later version published by
++the Free Software Foundation. If the Library does not specify a
++license version number, you may choose any version ever published by
++the Free Software Foundation.
++
++ 14. If you wish to incorporate parts of the Library into other free
++programs whose distribution conditions are incompatible with these,
++write to the author to ask for permission. For software which is
++copyrighted by the Free Software Foundation, write to the Free
++Software Foundation; we sometimes make exceptions for this. Our
++decision will be guided by the two goals of preserving the free status
++of all derivatives of our free software and of promoting the sharing
++and reuse of software generally.
++
++ NO WARRANTY
++
++ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
++WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
++EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
++OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
++KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
++IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
++PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
++LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
++THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
++
++ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
++WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
++AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
++FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
++CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
++LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
++RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
++FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
++SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
++DAMAGES.
++
++ END OF TERMS AND CONDITIONS
++
++ How to Apply These Terms to Your New Libraries
++
++ If you develop a new library, and you want it to be of the greatest
++possible use to the public, we recommend making it free software that
++everyone can redistribute and change. You can do so by permitting
++redistribution under these terms (or, alternatively, under the terms of the
++ordinary General Public License).
++
++ To apply these terms, attach the following notices to the library. It is
++safest to attach them to the start of each source file to most effectively
++convey the exclusion of warranty; and each file should have at least the
++"copyright" line and a pointer to where the full notice is found.
++
++ <one line to give the library's name and a brief idea of what it does.>

++ * @ingroup libavc
++ * @defgroup lavc_encdec send/receive encoding and decoding API overview
++ * @{
++ *
++ * The avcodec_send_packet()/avcodec_receive_frame()/avcodec_send_frame()/
++ * avcodec_receive_packet() functions provide an encode/decode API, which
++ * decouples input and output.
++ *
++ * The API is very similar for encoding/decoding and audio/video, and works as
++ * follows:
++ * - Set up and open the AVCodecContext as usual.
++ * - Send valid input:
++ * - For decoding, call avcodec_send_packet() to give the decoder raw
++ * compressed data in an AVPacket.
++ * - For encoding, call avcodec_send_frame() to give the encoder an AVFrame
++ * containing uncompressed audio or video.
++ * In both cases, it is recommended that AVPackets and AVFrames are
++ * refcounted, or libavcodec might have to copy the input data. (libavformat
++ * always returns refcounted AVPackets, and av_frame_get_buffer() allocates
++ * refcounted AVFrames.)
++ * - Receive output in a loop. Periodically call one of the avcodec_receive_*()
++ * functions and process their output:
++ * - For decoding, call avcodec_receive_frame(). On success, it will return
++ * an AVFrame containing uncompressed audio or video data.
++ * - For encoding, call avcodec_receive_packet(). On success, it will return
++ * an AVPacket with a compressed frame.
++ * Repeat this call until it returns AVERROR(EAGAIN) or an error. The
++ * AVERROR(EAGAIN) return value means that new input data is required to
++ * return new output. In this case, continue with sending input. For each
++ * input frame/packet, the codec will typically return 1 output frame/packet,
++ * but it can also be 0 or more than 1.
++ *
++ * At the beginning of decoding or encoding, the codec might accept multiple
++ * input frames/packets without returning a frame, until its internal buffers
++ * are filled. This situation is handled transparently if you follow the steps
++ * outlined above.
++ *
++ * In theory, sending input can result in EAGAIN - this should happen only if
++ * not all output was received. You can use this to structure alternative decode
++ * or encode loops other than the one suggested above. For example, you could
++ * try sending new input on each iteration, and try to receive output if that
++ * returns EAGAIN.
++ *
++ * End of stream situations. These require "flushing" (aka draining) the codec,
++ * as the codec might buffer multiple frames or packets internally for
++ * performance or out of necessity (consider B-frames).
++ * This is handled as follows:
++ * - Instead of valid input, send NULL to the avcodec_send_packet() (decoding)
++ * or avcodec_send_frame() (encoding) functions. This will enter draining
++ * mode.
++ * - Call avcodec_receive_frame() (decoding) or avcodec_receive_packet()
++ * (encoding) in a loop until AVERROR_EOF is returned. The functions will
++ * not return AVERROR(EAGAIN), unless you forgot to enter draining mode.
++ * - Before decoding can be resumed again, the codec has to be reset with
++ * avcodec_flush_buffers().
++ *
++ * Using the API as outlined above is highly recommended. But it is also
++ * possible to call functions outside of this rigid schema. For example, you can
++ * call avcodec_send_packet() repeatedly without calling
++ * avcodec_receive_frame(). In this case, avcodec_send_packet() will succeed
++ * until the codec's internal buffer has been filled up (which is typically of
++ * size 1 per output frame, after initial input), and then reject input with
++ * AVERROR(EAGAIN). Once it starts rejecting input, you have no choice but to
++ * read at least some output.
++ *
++ * Not all codecs will follow a rigid and predictable dataflow; the only
++ * guarantee is that an AVERROR(EAGAIN) return value on a send/receive call on
++ * one end implies that a receive/send call on the other end will succeed, or
++ * at least will not fail with AVERROR(EAGAIN). In general, no codec will
++ * permit unlimited buffering of input or output.
++ *
++ * This API replaces the following legacy functions:
++ * - avcodec_decode_video2() and avcodec_decode_audio4():
++ * Use avcodec_send_packet() to feed input to the decoder, then use
++ * avcodec_receive_frame() to receive decoded frames after each packet.
++ * Unlike with the old video decoding API, multiple frames might result from
++ * a packet. For audio, splitting the input packet into frames by partially
++ * decoding packets becomes transparent to the API user. You never need to
++ * feed an AVPacket to the API twice (unless it is rejected with AVERROR(EAGAIN) - then
++ * no data was read from the packet).
++ * Additionally, sending a flush/draining packet is required only once.
++ * - avcodec_encode_video2()/avcodec_encode_audio2():
++ * Use avcodec_send_frame() to feed input to the encoder, then use
++ * avcodec_receive_packet() to receive encoded packets.
++ * Providing user-allocated buffers for avcodec_receive_packet() is not
++ * possible.
++ * - The new API does not handle subtitles yet.
++ *
++ * Mixing new and old function calls on the same AVCodecContext is not allowed,
++ * and will result in undefined behavior.
++ *
++ * Some codecs might require using the new API; using the old API will return
++ * an error when calling it. All codecs support the new API.
++ *
++ * A codec is not allowed to return AVERROR(EAGAIN) for both sending and receiving. This
++ * would be an invalid state, which could put the codec user into an endless
++ * loop. The API has no concept of time either: it cannot happen that trying to
++ * do avcodec_send_packet() results in AVERROR(EAGAIN), but a repeated call 1 second
++ * later accepts the packet (with no other receive/flush API calls involved).
++ * The API is a strict state machine, and the passage of time is not supposed
++ * to influence it. Some timing-dependent behavior might still be deemed
++ * acceptable in certain cases. But it must never result in both send/receive
++ * returning EAGAIN at the same time at any point. It must also absolutely be
++ * avoided that the current state is "unstable" and can "flip-flop" between
++ * the send/receive APIs allowing progress. For example, it's not allowed that
++ * the codec randomly decides that it actually wants to consume a packet now
++ * instead of returning a frame, after it just returned AVERROR(EAGAIN) on an
++ * avcodec_send_packet() call.

++ * this means is, you may set however many entries in buf[] you feel necessary.
++ * Each buffer must be reference-counted using the AVBuffer API (see description
++ * of buf[] below).
++ *
++ * The following fields will be set in the frame before this callback is
++ * called:
++ * - format
++ * - width, height (video only)
++ * - sample_rate, channel_layout, nb_samples (audio only)
++ * Their values may differ from the corresponding values in
++ * AVCodecContext. This callback must use the frame values, not the codec
++ * context values, to calculate the required buffer size.
++ *
++ * This callback must fill the following fields in the frame:
++ * - data[]
++ * - linesize[]
++ * - extended_data:
++ * * if the data is planar audio with more than 8 channels, then this
++ * callback must allocate and fill extended_data to contain all pointers
++ * to all data planes. data[] must hold as many pointers as it can.
++ * extended_data must be allocated with av_malloc() and will be freed in
++ * av_frame_unref().
++ * * otherwise extended_data must point to data
++ * - buf[] must contain one or more pointers to AVBufferRef structures. Each of
++ * the frame's data and extended_data pointers must be contained in these. That
++ * is, one AVBufferRef for each allocated chunk of memory, not necessarily one
++ * AVBufferRef per data[] entry. See: av_buffer_create(), av_buffer_alloc(),
++ * and av_buffer_ref().
++ * - extended_buf and nb_extended_buf must be allocated with av_malloc() by
++ * this callback and filled with the extra buffers if there are more
++ * buffers than buf[] can hold. extended_buf will be freed in
++ * av_frame_unref().
++ *
++ * If AV_CODEC_CAP_DR1 is not set then get_buffer2() must call
++ * avcodec_default_get_buffer2() instead of providing buffers allocated by
++ * some other means.
++ *
++ * Each data plane must be aligned to the maximum required by the target
++ * CPU.
++ *
++ * @see avcodec_default_get_buffer2()
++ *
++ * Video:
++ *
++ * If AV_GET_BUFFER_FLAG_REF is set in flags then the frame may be reused
++ * (read and/or written to if it is writable) later by libavcodec.
++ *
++ * avcodec_align_dimensions2() should be used to find the required width and
++ * height, as they normally need to be rounded up to the next multiple of 16.
++ *
++ * Some decoders do not support linesizes changing between frames.
++ *
++ * If frame multithreading is used and thread_safe_callbacks is set,
++ * this callback may be called from a different thread, but not from more
++ * than one at once. Does not need to be reentrant.
++ *
++ * @see avcodec_align_dimensions2()
++ *
++ * Audio:
++ *
++ * Decoders request a buffer of a particular size by setting
++ * AVFrame.nb_samples prior to calling get_buffer2(). The decoder may,
++ * however, utilize only part of the buffer by setting AVFrame.nb_samples
++ * to a smaller value in the output frame.
++ *
++ * As a convenience, av_samples_get_buffer_size() and
++ * av_samples_fill_arrays() in libavutil may be used by custom get_buffer2()
++ * functions to find the required data size and to fill data pointers and
++ * linesize. In AVFrame.linesize, only linesize[0] may be set for audio
++ * since all planes must be the same size.

++ * Create and return a AVHWFramesContext with values adequate for hardware
++ * decoding. This is meant to get called from the get_format callback, and is
++ * a helper for preparing a AVHWFramesContext for AVCodecContext.hw_frames_ctx.
++ * This API is for decoding with certain hardware acceleration modes/APIs only.
++ *
++ * The returned AVHWFramesContext is not initialized. The caller must do this
++ * with av_hwframe_ctx_init().
++ *
++ * Calling this function is not a requirement, but makes it simpler to avoid
++ * codec or hardware API specific details when manually allocating frames.
++ *
++ * Alternatively to this, an API user can set AVCodecContext.hw_device_ctx,
++ * which sets up AVCodecContext.hw_frames_ctx fully automatically, and makes
++ * it unnecessary to call this function or having to care about
++ * AVHWFramesContext initialization at all.
++ *
++ * There are a number of requirements for calling this function:
++ *
++ * - It must be called from get_format with the same avctx parameter that was
++ * passed to get_format. Calling it outside of get_format is not allowed, and
++ * can trigger undefined behavior.
++ * - The function is not always supported (see description of return values).
++ * Even if this function returns successfully, hwaccel initialization could
++ * fail later. (The degree to which implementations check whether the stream
++ * is actually supported varies. Some do this check only after the user's
++ * get_format callback returns.)
++ * - The hw_pix_fmt must be one of the choices suggested by get_format. If the
++ * user decides to use a AVHWFramesContext prepared with this API function,
++ * the user must return the same hw_pix_fmt from get_format.
++ * - The device_ref passed to this function must support the given hw_pix_fmt.
++ * - After calling this API function, it is the user's responsibility to
++ * initialize the AVHWFramesContext (returned by the out_frames_ref parameter),
++ * and to set AVCodecContext.hw_frames_ctx to it. If done, this must be done
++ * before returning from get_format (this is implied by the normal
++ * AVCodecContext.hw_frames_ctx API rules).
++ * - The AVHWFramesContext parameters may change every time time get_format is
++ * called. Also, AVCodecContext.hw_frames_ctx is reset before get_format. So
++ * you are inherently required to go through this process again on every
++ * get_format call.
++ * - It is perfectly possible to call this function without actually using
++ * the resulting AVHWFramesContext. One use-case might be trying to reuse a
++ * previously initialized AVHWFramesContext, and calling this API function
++ * only to test whether the required frame parameters have changed.
++ * - Fields that use dynamically allocated values of any kind must not be set
++ * by the user unless setting them is explicitly allowed by the documentation.
++ * If the user sets AVHWFramesContext.free and AVHWFramesContext.user_opaque,
++ * the new free callback must call the potentially set previous free callback.
++ * This API call may set any dynamically allocated fields, including the free
++ * callback.
++ *
++ * The function will set at least the following fields on AVHWFramesContext
++ * (potentially more, depending on hwaccel API):
++ *
++ * - All fields set by av_hwframe_ctx_alloc().
++ * - Set the format field to hw_pix_fmt.
++ * - Set the sw_format field to the most suited and most versatile format. (An
++ * implication is that this will prefer generic formats over opaque formats
++ * with arbitrary restrictions, if possible.)
++ * - Set the width/height fields to the coded frame size, rounded up to the
++ * API-specific minimum alignment.
++ * - Only _if_ the hwaccel requires a pre-allocated pool: set the initial_pool_size
++ * field to the number of maximum reference surfaces possible with the codec,
++ * plus 1 surface for the user to work (meaning the user can safely reference
++ * at most 1 decoded surface at a time), plus additional buffering introduced
++ * by frame threading. If the hwaccel does not require pre-allocation, the
++ * field is left to 0, and the decoder will allocate new surfaces on demand
++ * during decoding.
++ * - Possibly AVHWFramesContext.hwctx fields, depending on the underlying
++ * hardware API.
++ *
++ * Essentially, out_frames_ref returns the same as av_hwframe_ctx_alloc(), but
++ * with basic frame parameters set.
++ *
++ * The function is stateless, and does not change the AVCodecContext or the
++ * device_ref AVHWDeviceContext.
++ *
++ * @param avctx The context which is currently calling get_format, and which
++ * implicitly contains all state needed for filling the returned
++ * AVHWFramesContext properly.
++ * @param device_ref A reference to the AVHWDeviceContext describing the device
++ * which will be used by the hardware decoder.
++ * @param hw_pix_fmt The hwaccel format you are going to return from get_format.
++ * @param out_frames_ref On success, set to a reference to an _uninitialized_
++ * AVHWFramesContext, created from the given device_ref.
++ * Fields will be set to values required for decoding.
++ * Not changed if an error is returned.
++ * @return zero on success, a negative value on error. The following error codes
++ * have special semantics:
++ * AVERROR(ENOENT): the decoder does not support this functionality. Setup
++ * is always manual, or it is a decoder which does not
++ * support setting AVCodecContext.hw_frames_ctx at all,
++ * or it is a software format.
++ * AVERROR(EINVAL): it is known that hardware decoding is not supported for
++ * this configuration, or the device_ref is not supported
++ * for the hwaccel referenced by hw_pix_fmt.

++ * provided by FFmpeg.
++ *
++ * @li @ref libavc "libavcodec" encoding/decoding library
++ * @li @ref lavfi "libavfilter" graph-based frame editing library

++ * @li @ref lpp "libpostproc" post processing library
++ * @li @ref libsws "libswscale" color conversion and scaling library
++ *
++ * @section ffmpeg_versioning Versioning and compatibility
++ *
++ * Each of the FFmpeg libraries contains a version.h header, which defines a
++ * major, minor and micro version number with the
++ * <em>LIBRARYNAME_VERSION_{MAJOR,MINOR,MICRO}</em> macros. The major version
++ * number is incremented with backward incompatible changes - e.g. removing
++ * parts of the public API, reordering public struct members, etc. The minor
++ * version number is incremented for backward compatible API changes or major
++ * new features - e.g. adding a new public function or a new decoder. The micro
++ * version number is incremented for smaller changes that a calling program
++ * might still want to check for - e.g. changing behavior in a previously
++ * unspecified situation.
++ *
++ * FFmpeg guarantees backward API and ABI compatibility for each library as long
++ * as its major version number is unchanged. This means that no public symbols
++ * will be removed or renamed. Types and names of the public struct members and
++ * values of public macros and enums will remain the same (unless they were
++ * explicitly declared as not part of the public API). Documented behavior will
++ * not change.
++ *
++ * In other words, any correct program that works with a given FFmpeg snapshot
++ * should work just as well without any changes with any later snapshot with the
++ * same major versions. This applies to both rebuilding the program against new
++ * FFmpeg versions or to replacing the dynamic FFmpeg libraries that a program
++ * links against.
++ *

++ * @{
++ * AVBuffer is an API for reference-counted data buffers.
++ *
++ * There are two core objects in this API -- AVBuffer and AVBufferRef. AVBuffer
++ * represents the data buffer itself; it is opaque and not meant to be accessed
++ * by the caller directly, but only through AVBufferRef. However, the caller may
++ * e.g. compare two AVBuffer pointers to check whether two different references
++ * are describing the same data buffer. AVBufferRef represents a single
++ * reference to an AVBuffer and it is the object that may be manipulated by the
++ * caller directly.
++ *
++ * There are two functions provided for creating a new AVBuffer with a single
++ * reference -- av_buffer_alloc() to just allocate a new buffer, and
++ * av_buffer_create() to wrap an existing array in an AVBuffer. From an existing
++ * reference, additional references may be created with av_buffer_ref().
++ * Use av_buffer_unref() to free a reference (this will automatically free the
++ * data once all the references are freed).
++ *
++ * The convention throughout this API and the rest of FFmpeg is such that the
++ * buffer is considered writable if there exists only one reference to it (and
++ * it has not been marked as read-only). The av_buffer_is_writable() function is
++ * provided to check whether this is true and av_buffer_make_writable() will
++ * automatically create a new writable buffer when necessary.
++ * Of course nothing prevents the calling code from violating this convention,
++ * however that is safe only when all the existing references are under its
++ * control.
++ *
++ * @note Referencing and unreferencing the buffers is thread-safe and thus
++ * may be done from multiple threads simultaneously without any need for
++ * additional locking.
++ *
++ * @note Two different references to the same buffer can point to different
++ * parts of the buffer (i.e. their AVBufferRef.data will not be equal).

++ * @addtogroup lavu_mem

++ *
++ * FFmpeg has several applications of memory that are not required of a typical
++ * program. For example, the computing-heavy components like video decoding and
++ * encoding can be sped up significantly through the use of aligned memory.
++ *
++ * However, for each of FFmpeg's applications of memory, there might not be a
++ * recognized or standardized API for that specific use. Memory alignment, for
++ * instance, varies wildly depending on operating systems, architectures, and
++ * compilers. Hence, this component of @ref libavutil is created to make
++ * dealing with memory consistently possible on all platforms.

++ *
++ * libavutil supports two systems of appending elements onto a dynamically
++ * allocated array, the first one storing the pointer to the value in the

++ * caller is responsible for maintaining a variable containing the length of
++ * the array, as well as freeing of the array after use.
++ *
++ * The first system stores pointers to values in a block of dynamically
++ * allocated memory. Since only pointers are stored, the function does not need
++ * to know the size of the type. Both av_dynarray_add() and
++ * av_dynarray_add_nofree() implement this system.
++ *
++ * @code

++ * Pixel format.
++ *
++ * @note
++ * AV_PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA
++ * color is put together as:
++ * (A << 24) | (R << 16) | (G << 8) | B
++ * This is stored as BGRA on little-endian CPU architectures and ARGB on
++ * big-endian CPUs.
++ *
++ * @par
++ * When the pixel format is palettized RGB32 (AV_PIX_FMT_PAL8), the palettized
++ * image data is stored in AVFrame.data[0]. The palette is transported in
++ * AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
++ * formatted the same as in AV_PIX_FMT_RGB32 described above (i.e., it is
++ * also endian-specific). Note also that the individual RGB32 palette
++ * components stored in AVFrame.data[1] should be in the range 0..255.
++ * This is important as many custom PAL8 video codecs that were designed
++ * to run on the IBM VGA graphics adapter use 6-bit palette components.
++ *
++ * @par
++ * For all the 8 bits per pixel formats, an RGB32 palette is in data[1] like
++ * for pal8. This palette is filled in automatically by the function
++ * allocating the picture.

++ GNU LESSER GENERAL PUBLIC LICENSE
++ Version 2.1, February 1999
++
++ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
++ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
++ Everyone is permitted to copy and distribute verbatim copies
++ of this license document, but changing it is not allowed.
++
++[This is the first released version of the Lesser GPL. It also counts
++ as the successor of the GNU Library Public License, version 2, hence
++ the version number 2.1.]
++
++ Preamble
++
++ The licenses for most software are designed to take away your
++freedom to share and change it. By contrast, the GNU General Public
++Licenses are intended to guarantee your freedom to share and change
++free software--to make sure the software is free for all its users.
++
++ This license, the Lesser General Public License, applies to some
++specially designated software packages--typically libraries--of the
++Free Software Foundation and other authors who decide to use it. You
++can use it too, but we suggest you first think carefully about whether
++this license or the ordinary General Public License is the better
++strategy to use in any particular case, based on the explanations below.
++
++ When we speak of free software, we are referring to freedom of use,
++not price. Our General Public Licenses are designed to make sure that
++you have the freedom to distribute copies of free software (and charge
++for this service if you wish); that you receive source code or can get
++it if you want it; that you can change the software and use pieces of
++it in new free programs; and that you are informed that you can do
++these things.
++
++ To protect your rights, we need to make restrictions that forbid
++distributors to deny you these rights or to ask you to surrender these
++rights. These restrictions translate to certain responsibilities for
++you if you distribute copies of the library or if you modify it.
++
++ For example, if you distribute copies of the library, whether gratis
++or for a fee, you must give the recipients all the rights that we gave
++you. You must make sure that they, too, receive or can get the source
++code. If you link other code with the library, you must provide
++complete object files to the recipients, so that they can relink them
++with the library after making changes to the library and recompiling
++it. And you must show them these terms so they know their rights.
++
++ We protect your rights with a two-step method: (1) we copyright the
++library, and (2) we offer you this license, which gives you legal
++permission to copy, distribute and/or modify the library.
++
++ To protect each distributor, we want to make it very clear that
++there is no warranty for the free library. Also, if the library is
++modified by someone else and passed on, the recipients should know
++that what they have is not the original version, so that the original
++author's reputation will not be affected by problems that might be
++introduced by others.
++
++ Finally, software patents pose a constant threat to the existence of
++any free program. We wish to make sure that a company cannot
++effectively restrict the users of a free program by obtaining a
++restrictive license from a patent holder. Therefore, we insist that
++any patent license obtained for a version of the library must be
++consistent with the full freedom of use specified in this license.
++
++ Most GNU software, including some libraries, is covered by the
++ordinary GNU General Public License. This license, the GNU Lesser
++General Public License, applies to certain designated libraries, and
++is quite different from the ordinary General Public License. We use
++this license for certain libraries in order to permit linking those
++libraries into non-free programs.
++
++ When a program is linked with a library, whether statically or using
++a shared library, the combination of the two is legally speaking a
++combined work, a derivative of the original library. The ordinary
++General Public License therefore permits such linking only if the
++entire combination fits its criteria of freedom. The Lesser General
++Public License permits more lax criteria for linking other code with
++the library.
++
++ We call this license the "Lesser" General Public License because it
++does Less to protect the user's freedom than the ordinary General
++Public License. It also provides other free software developers Less
++of an advantage over competing non-free programs. These disadvantages
++are the reason we use the ordinary General Public License for many
++libraries. However, the Lesser license provides advantages in certain
++special circumstances.
++
++ For example, on rare occasions, there may be a special need to
++encourage the widest possible use of a certain library, so that it becomes
++a de-facto standard. To achieve this, non-free programs must be
++allowed to use the library. A more frequent case is that a free
++library does the same job as widely used non-free libraries. In this
++case, there is little to gain by limiting the free library to free
++software only, so we use the Lesser General Public License.
++
++ In other cases, permission to use a particular library in non-free
++programs enables a greater number of people to use a large body of
++free software. For example, permission to use the GNU C Library in
++non-free programs enables many more people to use the whole GNU
++operating system, as well as its variant, the GNU/Linux operating
++system.
++
++ Although the Lesser General Public License is Less protective of the
++users' freedom, it does ensure that the user of a program that is
++linked with the Library has the freedom and the wherewithal to run
++that program using a modified version of the Library.
++
++ The precise terms and conditions for copying, distribution and
++modification follow. Pay close attention to the difference between a
++"work based on the library" and a "work that uses the library". The
++former contains code derived from the library, whereas the latter must
++be combined with the library in order to run.
++
++ GNU LESSER GENERAL PUBLIC LICENSE
++ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
++
++ 0. This License Agreement applies to any software library or other
++program which contains a notice placed by the copyright holder or
++other authorized party saying it may be distributed under the terms of
++this Lesser General Public License (also called "this License").
++Each licensee is addressed as "you".
++
++ A "library" means a collection of software functions and/or data
++prepared so as to be conveniently linked with application programs
++(which use some of those functions and data) to form executables.
++
++ The "Library", below, refers to any such software library or work
++which has been distributed under these terms. A "work based on the
++Library" means either the Library or any derivative work under
++copyright law: that is to say, a work containing the Library or a
++portion of it, either verbatim or with modifications and/or translated
++straightforwardly into another language. (Hereinafter, translation is
++included without limitation in the term "modification".)
++
++ "Source code" for a work means the preferred form of the work for
++making modifications to it. For a library, complete source code means
++all the source code for all modules it contains, plus any associated
++interface definition files, plus the scripts used to control compilation
++and installation of the library.
++
++ Activities other than copying, distribution and modification are not
++covered by this License; they are outside its scope. The act of
++running a program using the Library is not restricted, and output from
++such a program is covered only if its contents constitute a work based
++on the Library (independent of the use of the Library in a tool for
++writing it). Whether that is true depends on what the Library does
++and what the program that uses the Library does.
++
++ 1. You may copy and distribute verbatim copies of the Library's
++complete source code as you receive it, in any medium, provided that
++you conspicuously and appropriately publish on each copy an
++appropriate copyright notice and disclaimer of warranty; keep intact
++all the notices that refer to this License and to the absence of any
++warranty; and distribute a copy of this License along with the
++Library.
++
++ You may charge a fee for the physical act of transferring a copy,
++and you may at your option offer warranty protection in exchange for a
++fee.
++
++ 2. You may modify your copy or copies of the Library or any portion
++of it, thus forming a work based on the Library, and copy and
++distribute such modifications or work under the terms of Section 1
++above, provided that you also meet all of these conditions:
++
++ a) The modified work must itself be a software library.
++
++ b) You must cause the files modified to carry prominent notices
++ stating that you changed the files and the date of any change.
++
++ c) You must cause the whole of the work to be licensed at no
++ charge to all third parties under the terms of this License.
++
++ d) If a facility in the modified Library refers to a function or a
++ table of data to be supplied by an application program that uses
++ the facility, other than as an argument passed when the facility
++ is invoked, then you must make a good faith effort to ensure that,
++ in the event an application does not supply such function or
++ table, the facility still operates, and performs whatever part of
++ its purpose remains meaningful.
++
++ (For example, a function in a library to compute square roots has
++ a purpose that is entirely well-defined independent of the
++ application. Therefore, Subsection 2d requires that any
++ application-supplied function or table used by this function must
++ be optional: if the application does not supply it, the square
++ root function must still compute square roots.)
++
++These requirements apply to the modified work as a whole. If
++identifiable sections of that work are not derived from the Library,
++and can be reasonably considered independent and separate works in
++themselves, then this License, and its terms, do not apply to those
++sections when you distribute them as separate works. But when you
++distribute the same sections as part of a whole which is a work based
++on the Library, the distribution of the whole must be on the terms of
++this License, whose permissions for other licensees extend to the
++entire whole, and thus to each and every part regardless of who wrote
++it.
++
++Thus, it is not the intent of this section to claim rights or contest
++your rights to work written entirely by you; rather, the intent is to
++exercise the right to control the distribution of derivative or
++collective works based on the Library.
++
++In addition, mere aggregation of another work not based on the Library
++with the Library (or with a work based on the Library) on a volume of
++a storage or distribution medium does not bring the other work under
++the scope of this License.
++
++ 3. You may opt to apply the terms of the ordinary GNU General Public
++License instead of this License to a given copy of the Library. To do
++this, you must alter all the notices that refer to this License, so
++that they refer to the ordinary GNU General Public License, version 2,
++instead of to this License. (If a newer version than version 2 of the
++ordinary GNU General Public License has appeared, then you can specify
++that version instead if you wish.) Do not make any other change in
++these notices.
++
++ Once this change is made in a given copy, it is irreversible for
++that copy, so the ordinary GNU General Public License applies to all
++subsequent copies and derivative works made from that copy.
++
++ This option is useful when you wish to copy part of the code of
++the Library into a program that is not a library.
++
++ 4. You may copy and distribute the Library (or a portion or
++derivative of it, under Section 2) in object code or executable form
++under the terms of Sections 1 and 2 above provided that you accompany
++it with the complete corresponding machine-readable source code, which
++must be distributed under the terms of Sections 1 and 2 above on a
++medium customarily used for software interchange.
++
++ If distribution of object code is made by offering access to copy
++from a designated place, then offering equivalent access to copy the
++source code from the same place satisfies the requirement to
++distribute the source code, even though third parties are not
++compelled to copy the source along with the object code.
++
++ 5. A program that contains no derivative of any portion of the
++Library, but is designed to work with the Library by being compiled or
++linked with it, is called a "work that uses the Library". Such a
++work, in isolation, is not a derivative work of the Library, and
++therefore falls outside the scope of this License.
++
++ However, linking a "work that uses the Library" with the Library
++creates an executable that is a derivative of the Library (because it
++contains portions of the Library), rather than a "work that uses the
++library". The executable is therefore covered by this License.
++Section 6 states terms for distribution of such executables.
++
++ When a "work that uses the Library" uses material from a header file
++that is part of the Library, the object code for the work may be a
++derivative work of the Library even though the source code is not.
++Whether this is true is especially significant if the work can be
++linked without the Library, or if the work is itself a library. The
++threshold for this to be true is not precisely defined by law.
++
++ If such an object file uses only numerical parameters, data
++structure layouts and accessors, and small macros and small inline
++functions (ten lines or less in length), then the use of the object
++file is unrestricted, regardless of whether it is legally a derivative
++work. (Executables containing this object code plus portions of the
++Library will still fall under Section 6.)
++
++ Otherwise, if the work is a derivative of the Library, you may
++distribute the object code for the work under the terms of Section 6.
++Any executables containing that work also fall under Section 6,
++whether or not they are linked directly with the Library itself.
++
++ 6. As an exception to the Sections above, you may also combine or
++link a "work that uses the Library" with the Library to produce a
++work containing portions of the Library, and distribute that work
++under terms of your choice, provided that the terms permit
++modification of the work for the customer's own use and reverse
++engineering for debugging such modifications.
++
++ You must give prominent notice with each copy of the work that the
++Library is used in it and that the Library and its use are covered by
++this License. You must supply a copy of this License. If the work
++during execution displays copyright notices, you must include the
++copyright notice for the Library among them, as well as a reference
++directing the user to the copy of this License. Also, you must do one
++of these things:
++
++ a) Accompany the work with the complete corresponding
++ machine-readable source code for the Library including whatever
++ changes were used in the work (which must be distributed under
++ Sections 1 and 2 above); and, if the work is an executable linked
++ with the Library, with the complete machine-readable "work that
++ uses the Library", as object code and/or source code, so that the
++ user can modify the Library and then relink to produce a modified
++ executable containing the modified Library. (It is understood
++ that the user who changes the contents of definitions files in the
++ Library will not necessarily be able to recompile the application
++ to use the modified definitions.)
++
++ b) Use a suitable shared library mechanism for linking with the
++ Library. A suitable mechanism is one that (1) uses at run time a
++ copy of the library already present on the user's computer system,
++ rather than copying library functions into the executable, and (2)
++ will operate properly with a modified version of the library, if
++ the user installs one, as long as the modified version is
++ interface-compatible with the version that the work was made with.
++
++ c) Accompany the work with a written offer, valid for at
++ least three years, to give the same user the materials
++ specified in Subsection 6a, above, for a charge no more
++ than the cost of performing this distribution.
++
++ d) If distribution of the work is made by offering access to copy
++ from a designated place, offer equivalent access to copy the above
++ specified materials from the same place.
++
++ e) Verify that the user has already received a copy of these
++ materials or that you have already sent this user a copy.
++
++ For an executable, the required form of the "work that uses the
++Library" must include any data and utility programs needed for
++reproducing the executable from it. However, as a special exception,
++the materials to be distributed need not include anything that is
++normally distributed (in either source or binary form) with the major
++components (compiler, kernel, and so on) of the operating system on
++which the executable runs, unless that component itself accompanies
++the executable.
++
++ It may happen that this requirement contradicts the license
++restrictions of other proprietary libraries that do not normally
++accompany the operating system. Such a contradiction means you cannot
++use both them and the Library together in an executable that you
++distribute.
++
++ 7. You may place library facilities that are a work based on the
++Library side-by-side in a single library together with other library
++facilities not covered by this License, and distribute such a combined
++library, provided that the separate distribution of the work based on
++the Library and of the other library facilities is otherwise
++permitted, and provided that you do these two things:
++
++ a) Accompany the combined library with a copy of the same work
++ based on the Library, uncombined with any other library
++ facilities. This must be distributed under the terms of the
++ Sections above.
++
++ b) Give prominent notice with the combined library of the fact
++ that part of it is a work based on the Library, and explaining
++ where to find the accompanying uncombined form of the same work.
++
++ 8. You may not copy, modify, sublicense, link with, or distribute
++the Library except as expressly provided under this License. Any
++attempt otherwise to copy, modify, sublicense, link with, or
++distribute the Library is void, and will automatically terminate your
++rights under this License. However, parties who have received copies,
++or rights, from you under this License will not have their licenses
++terminated so long as such parties remain in full compliance.
++
++ 9. You are not required to accept this License, since you have not
++signed it. However, nothing else grants you permission to modify or
++distribute the Library or its derivative works. These actions are
++prohibited by law if you do not accept this License. Therefore, by
++modifying or distributing the Library (or any work based on the
++Library), you indicate your acceptance of this License to do so, and
++all its terms and conditions for copying, distributing or modifying
++the Library or works based on it.
++
++ 10. Each time you redistribute the Library (or any work based on the
++Library), the recipient automatically receives a license from the
++original licensor to copy, distribute, link with or modify the Library
++subject to these terms and conditions. You may not impose any further
++restrictions on the recipients' exercise of the rights granted herein.
++You are not responsible for enforcing compliance by third parties with
++this License.
++
++ 11. If, as a consequence of a court judgment or allegation of patent
++infringement or for any other reason (not limited to patent issues),
++conditions are imposed on you (whether by court order, agreement or
++otherwise) that contradict the conditions of this License, they do not
++excuse you from the conditions of this License. If you cannot
++distribute so as to satisfy simultaneously your obligations under this
++License and any other pertinent obligations, then as a consequence you
++may not distribute the Library at all. For example, if a patent
++license would not permit royalty-free redistribution of the Library by
++all those who receive copies directly or indirectly through you, then
++the only way you could satisfy both it and this License would be to
++refrain entirely from distribution of the Library.
++
++If any portion of this section is held invalid or unenforceable under any
++particular circumstance, the balance of the section is intended to apply,
++and the section as a whole is intended to apply in other circumstances.
++
++It is not the purpose of this section to induce you to infringe any
++patents or other property right claims or to contest validity of any
++such claims; this section has the sole purpose of protecting the
++integrity of the free software distribution system which is
++implemented by public license practices. Many people have made
++generous contributions to the wide range of software distributed
++through that system in reliance on consistent application of that
++system; it is up to the author/donor to decide if he or she is willing
++to distribute software through any other system and a licensee cannot
++impose that choice.
++
++This section is intended to make thoroughly clear what is believed to
++be a consequence of the rest of this License.
++
++ 12. If the distribution and/or use of the Library is restricted in
++certain countries either by patents or by copyrighted interfaces, the
++original copyright holder who places the Library under this License may add
++an explicit geographical distribution limitation excluding those countries,
++so that distribution is permitted only in or among countries not thus
++excluded. In such case, this License incorporates the limitation as if
++written in the body of this License.
++
++ 13. The Free Software Foundation may publish revised and/or new
++versions of the Lesser General Public License from time to time.
++Such new versions will be similar in spirit to the present version,
++but may differ in detail to address new problems or concerns.
++
++Each version is given a distinguishing version number. If the Library
++specifies a version number of this License which applies to it and
++"any later version", you have the option of following the terms and
++conditions either of that version or of any later version published by
++the Free Software Foundation. If the Library does not specify a
++license version number, you may choose any version ever published by
++the Free Software Foundation.
++
++ 14. If you wish to incorporate parts of the Library into other free
++programs whose distribution conditions are incompatible with these,
++write to the author to ask for permission. For software which is
++copyrighted by the Free Software Foundation, write to the Free
++Software Foundation; we sometimes make exceptions for this. Our
++decision will be guided by the two goals of preserving the free status
++of all derivatives of our free software and of promoting the sharing
++and reuse of software generally.
++
++ NO WARRANTY
++
++ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
++WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
++EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
++OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
++KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
++IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
++PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
++LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
++THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
++
++ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
++WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
++AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU

++ * @ingroup libavc
++ * @defgroup lavc_encdec send/receive encoding and decoding API overview
++ * @{
++ *
++ * The avcodec_send_packet()/avcodec_receive_frame()/avcodec_send_frame()/
++ * avcodec_receive_packet() functions provide an encode/decode API, which
++ * decouples input and output.
++ *
++ * The API is very similar for encoding/decoding and audio/video, and works as
++ * follows:
++ * - Set up and open the AVCodecContext as usual.
++ * - Send valid input:
++ * - For decoding, call avcodec_send_packet() to give the decoder raw
++ * compressed data in an AVPacket.
++ * - For encoding, call avcodec_send_frame() to give the encoder an AVFrame
++ * containing uncompressed audio or video.
++ * In both cases, it is recommended that AVPackets and AVFrames are
++ * refcounted, or libavcodec might have to copy the input data. (libavformat
++ * always returns refcounted AVPackets, and av_frame_get_buffer() allocates
++ * refcounted AVFrames.)
++ * - Receive output in a loop. Periodically call one of the avcodec_receive_*()
++ * functions and process their output:
++ * - For decoding, call avcodec_receive_frame(). On success, it will return
++ * an AVFrame containing uncompressed audio or video data.
++ * - For encoding, call avcodec_receive_packet(). On success, it will return
++ * an AVPacket with a compressed frame.
++ * Repeat this call until it returns AVERROR(EAGAIN) or an error. The
++ * AVERROR(EAGAIN) return value means that new input data is required to
++ * return new output. In this case, continue with sending input. For each
++ * input frame/packet, the codec will typically return 1 output frame/packet,
++ * but it can also be 0 or more than 1.
++ *
++ * At the beginning of decoding or encoding, the codec might accept multiple
++ * input frames/packets without returning a frame, until its internal buffers
++ * are filled. This situation is handled transparently if you follow the steps
++ * outlined above.
++ *
++ * In theory, sending input can result in EAGAIN - this should happen only if
++ * not all output was received. You can use this to structure alternative decode
++ * or encode loops other than the one suggested above. For example, you could
++ * try sending new input on each iteration, and try to receive output if that
++ * returns EAGAIN.
++ *
++ * End of stream situations. These require "flushing" (aka draining) the codec,
++ * as the codec might buffer multiple frames or packets internally for
++ * performance or out of necessity (consider B-frames).
++ * This is handled as follows:
++ * - Instead of valid input, send NULL to the avcodec_send_packet() (decoding)
++ * or avcodec_send_frame() (encoding) functions. This will enter draining
++ * mode.
++ * - Call avcodec_receive_frame() (decoding) or avcodec_receive_packet()
++ * (encoding) in a loop until AVERROR_EOF is returned. The functions will
++ * not return AVERROR(EAGAIN), unless you forgot to enter draining mode.
++ * - Before decoding can be resumed again, the codec has to be reset with
++ * avcodec_flush_buffers().
++ *
++ * Using the API as outlined above is highly recommended. But it is also
++ * possible to call functions outside of this rigid schema. For example, you can
++ * call avcodec_send_packet() repeatedly without calling
++ * avcodec_receive_frame(). In this case, avcodec_send_packet() will succeed
++ * until the codec's internal buffer has been filled up (which is typically of
++ * size 1 per output frame, after initial input), and then reject input with
++ * AVERROR(EAGAIN). Once it starts rejecting input, you have no choice but to
++ * read at least some output.
++ *
++ * Not all codecs will follow a rigid and predictable dataflow; the only
++ * guarantee is that an AVERROR(EAGAIN) return value on a send/receive call on
++ * one end implies that a receive/send call on the other end will succeed, or
++ * at least will not fail with AVERROR(EAGAIN). In general, no codec will
++ * permit unlimited buffering of input or output.
++ *
++ * This API replaces the following legacy functions:
++ * - avcodec_decode_video2() and avcodec_decode_audio4():
++ * Use avcodec_send_packet() to feed input to the decoder, then use
++ * avcodec_receive_frame() to receive decoded frames after each packet.
++ * Unlike with the old video decoding API, multiple frames might result from
++ * a packet. For audio, splitting the input packet into frames by partially
++ * decoding packets becomes transparent to the API user. You never need to
++ * feed an AVPacket to the API twice (unless it is rejected with AVERROR(EAGAIN) - then
++ * no data was read from the packet).
++ * Additionally, sending a flush/draining packet is required only once.
++ * - avcodec_encode_video2()/avcodec_encode_audio2():
++ * Use avcodec_send_frame() to feed input to the encoder, then use
++ * avcodec_receive_packet() to receive encoded packets.
++ * Providing user-allocated buffers for avcodec_receive_packet() is not
++ * possible.
++ * - The new API does not handle subtitles yet.
++ *
++ * Mixing new and old function calls on the same AVCodecContext is not allowed,
++ * and will result in undefined behavior.
++ *
++ * Some codecs might require using the new API; using the old API will return
++ * an error when calling it. All codecs support the new API.
++ *
++ * A codec is not allowed to return AVERROR(EAGAIN) for both sending and receiving. This
++ * would be an invalid state, which could put the codec user into an endless
++ * loop. The API has no concept of time either: it cannot happen that trying to
++ * do avcodec_send_packet() results in AVERROR(EAGAIN), but a repeated call 1 second
++ * later accepts the packet (with no other receive/flush API calls involved).
++ * The API is a strict state machine, and the passage of time is not supposed
++ * to influence it. Some timing-dependent behavior might still be deemed
++ * acceptable in certain cases. But it must never result in both send/receive
++ * returning EAGAIN at the same time at any point. It must also absolutely be
++ * avoided that the current state is "unstable" and can "flip-flop" between
++ * the send/receive APIs allowing progress. For example, it's not allowed that
++ * the codec randomly decides that it actually wants to consume a packet now
++ * instead of returning a frame, after it just returned AVERROR(EAGAIN) on an
++ * avcodec_send_packet() call.

++ * this means is, you may set however many entries in buf[] you feel necessary.
++ * Each buffer must be reference-counted using the AVBuffer API (see description
++ * of buf[] below).
++ *
++ * The following fields will be set in the frame before this callback is
++ * called:
++ * - format
++ * - width, height (video only)
++ * - sample_rate, channel_layout, nb_samples (audio only)
++ * Their values may differ from the corresponding values in
++ * AVCodecContext. This callback must use the frame values, not the codec
++ * context values, to calculate the required buffer size.
++ *
++ * This callback must fill the following fields in the frame:
++ * - data[]
++ * - linesize[]
++ * - extended_data:
++ * * if the data is planar audio with more than 8 channels, then this
++ * callback must allocate and fill extended_data to contain all pointers
++ * to all data planes. data[] must hold as many pointers as it can.
++ * extended_data must be allocated with av_malloc() and will be freed in
++ * av_frame_unref().
++ * * otherwise extended_data must point to data
++ * - buf[] must contain one or more pointers to AVBufferRef structures. Each of
++ * the frame's data and extended_data pointers must be contained in these. That
++ * is, one AVBufferRef for each allocated chunk of memory, not necessarily one
++ * AVBufferRef per data[] entry. See: av_buffer_create(), av_buffer_alloc(),
++ * and av_buffer_ref().
++ * - extended_buf and nb_extended_buf must be allocated with av_malloc() by
++ * this callback and filled with the extra buffers if there are more
++ * buffers than buf[] can hold. extended_buf will be freed in
++ * av_frame_unref().
++ *
++ * If AV_CODEC_CAP_DR1 is not set then get_buffer2() must call
++ * avcodec_default_get_buffer2() instead of providing buffers allocated by
++ * some other means.
++ *
++ * Each data plane must be aligned to the maximum required by the target
++ * CPU.
++ *
++ * @see avcodec_default_get_buffer2()
++ *
++ * Video:
++ *
++ * If AV_GET_BUFFER_FLAG_REF is set in flags then the frame may be reused
++ * (read and/or written to if it is writable) later by libavcodec.
++ *
++ * avcodec_align_dimensions2() should be used to find the required width and
++ * height, as they normally need to be rounded up to the next multiple of 16.
++ *
++ * Some decoders do not support linesizes changing between frames.
++ *
++ * If frame multithreading is used and thread_safe_callbacks is set,
++ * this callback may be called from a different thread, but not from more
++ * than one at once. Does not need to be reentrant.
++ *
++ * @see avcodec_align_dimensions2()

++ *
++ * Decoders request a buffer of a particular size by setting
++ * AVFrame.nb_samples prior to calling get_buffer2(). The decoder may,
++ * however, utilize only part of the buffer by setting AVFrame.nb_samples
++ * to a smaller value in the output frame.
++ *
++ * As a convenience, av_samples_get_buffer_size() and
++ * av_samples_fill_arrays() in libavutil may be used by custom get_buffer2()
++ * functions to find the required data size and to fill data pointers and
++ * linesize. In AVFrame.linesize, only linesize[0] may be set for audio
++ * since all planes must be the same size.

++ * Create and return a AVHWFramesContext with values adequate for hardware
++ * decoding. This is meant to get called from the get_format callback, and is
++ * a helper for preparing a AVHWFramesContext for AVCodecContext.hw_frames_ctx.
++ * This API is for decoding with certain hardware acceleration modes/APIs only.
++ *
++ * The returned AVHWFramesContext is not initialized. The caller must do this
++ * with av_hwframe_ctx_init().
++ *
++ * Calling this function is not a requirement, but makes it simpler to avoid
++ * codec or hardware API specific details when manually allocating frames.
++ *
++ * Alternatively to this, an API user can set AVCodecContext.hw_device_ctx,
++ * which sets up AVCodecContext.hw_frames_ctx fully automatically, and makes
++ * it unnecessary to call this function or having to care about
++ * AVHWFramesContext initialization at all.
++ *
++ * There are a number of requirements for calling this function:
++ *
++ * - It must be called from get_format with the same avctx parameter that was
++ * passed to get_format. Calling it outside of get_format is not allowed, and
++ * can trigger undefined behavior.
++ * - The function is not always supported (see description of return values).
++ * Even if this function returns successfully, hwaccel initialization could
++ * fail later. (The degree to which implementations check whether the stream
++ * is actually supported varies. Some do this check only after the user's
++ * get_format callback returns.)
++ * - The hw_pix_fmt must be one of the choices suggested by get_format. If the
++ * user decides to use a AVHWFramesContext prepared with this API function,
++ * the user must return the same hw_pix_fmt from get_format.
++ * - The device_ref passed to this function must support the given hw_pix_fmt.
++ * - After calling this API function, it is the user's responsibility to
++ * initialize the AVHWFramesContext (returned by the out_frames_ref parameter),
++ * and to set AVCodecContext.hw_frames_ctx to it. If done, this must be done
++ * before returning from get_format (this is implied by the normal
++ * AVCodecContext.hw_frames_ctx API rules).
++ * - The AVHWFramesContext parameters may change every time time get_format is
++ * called. Also, AVCodecContext.hw_frames_ctx is reset before get_format. So
++ * you are inherently required to go through this process again on every
++ * get_format call.
++ * - It is perfectly possible to call this function without actually using
++ * the resulting AVHWFramesContext. One use-case might be trying to reuse a
++ * previously initialized AVHWFramesContext, and calling this API function
++ * only to test whether the required frame parameters have changed.
++ * - Fields that use dynamically allocated values of any kind must not be set
++ * by the user unless setting them is explicitly allowed by the documentation.
++ * If the user sets AVHWFramesContext.free and AVHWFramesContext.user_opaque,
++ * the new free callback must call the potentially set previous free callback.
++ * This API call may set any dynamically allocated fields, including the free
++ * callback.
++ *
++ * The function will set at least the following fields on AVHWFramesContext
++ * (potentially more, depending on hwaccel API):
++ *
++ * - All fields set by av_hwframe_ctx_alloc().
++ * - Set the format field to hw_pix_fmt.
++ * - Set the sw_format field to the most suited and most versatile format. (An
++ * implication is that this will prefer generic formats over opaque formats
++ * with arbitrary restrictions, if possible.)
++ * - Set the width/height fields to the coded frame size, rounded up to the
++ * API-specific minimum alignment.
++ * - Only _if_ the hwaccel requires a pre-allocated pool: set the initial_pool_size
++ * field to the number of maximum reference surfaces possible with the codec,
++ * plus 1 surface for the user to work (meaning the user can safely reference
++ * at most 1 decoded surface at a time), plus additional buffering introduced
++ * by frame threading. If the hwaccel does not require pre-allocation, the
++ * field is left to 0, and the decoder will allocate new surfaces on demand
++ * during decoding.
++ * - Possibly AVHWFramesContext.hwctx fields, depending on the underlying
++ * hardware API.
++ *
++ * Essentially, out_frames_ref returns the same as av_hwframe_ctx_alloc(), but
++ * with basic frame parameters set.
++ *
++ * The function is stateless, and does not change the AVCodecContext or the
++ * device_ref AVHWDeviceContext.
++ *
++ * @param avctx The context which is currently calling get_format, and which
++ * implicitly contains all state needed for filling the returned
++ * AVHWFramesContext properly.
++ * @param device_ref A reference to the AVHWDeviceContext describing the device
++ * which will be used by the hardware decoder.
++ * @param hw_pix_fmt The hwaccel format you are going to return from get_format.
++ * @param out_frames_ref On success, set to a reference to an _uninitialized_
++ * AVHWFramesContext, created from the given device_ref.
++ * Fields will be set to values required for decoding.
++ * Not changed if an error is returned.
++ * @return zero on success, a negative value on error. The following error codes
++ * have special semantics:
++ * AVERROR(ENOENT): the decoder does not support this functionality. Setup
++ * is always manual, or it is a decoder which does not
++ * support setting AVCodecContext.hw_frames_ctx at all,
++ * or it is a software format.
++ * AVERROR(EINVAL): it is known that hardware decoding is not supported for
++ * this configuration, or the device_ref is not supported

++ * This document describes the usage of the different libraries
++ * provided by FFmpeg.
++ *
++ * @li @ref libavc "libavcodec" encoding/decoding library
++ * @li @ref lavfi "libavfilter" graph-based frame editing library
++ * @li @ref libavf "libavformat" I/O and muxing/demuxing library

++ * @li @ref lpp "libpostproc" post processing library
++ * @li @ref libsws "libswscale" color conversion and scaling library
++ *
++ * @section ffmpeg_versioning Versioning and compatibility
++ *
++ * Each of the FFmpeg libraries contains a version.h header, which defines a
++ * major, minor and micro version number with the
++ * <em>LIBRARYNAME_VERSION_{MAJOR,MINOR,MICRO}</em> macros. The major version
++ * number is incremented with backward incompatible changes - e.g. removing
++ * parts of the public API, reordering public struct members, etc. The minor
++ * version number is incremented for backward compatible API changes or major
++ * new features - e.g. adding a new public function or a new decoder. The micro
++ * version number is incremented for smaller changes that a calling program
++ * might still want to check for - e.g. changing behavior in a previously
++ * unspecified situation.
++ *
++ * FFmpeg guarantees backward API and ABI compatibility for each library as long
++ * as its major version number is unchanged. This means that no public symbols
++ * will be removed or renamed. Types and names of the public struct members and
++ * values of public macros and enums will remain the same (unless they were
++ * explicitly declared as not part of the public API). Documented behavior will
++ * not change.
++ *
++ * In other words, any correct program that works with a given FFmpeg snapshot
++ * should work just as well without any changes with any later snapshot with the
++ * same major versions. This applies to both rebuilding the program against new
++ * FFmpeg versions or to replacing the dynamic FFmpeg libraries that a program
++ * links against.
++ *
++ * However, new public symbols may be added and new members may be appended to
++ * public structs whose size is not part of public ABI (most public structs in
++ * FFmpeg). New macros and enum values may be added. Behavior in undocumented
++ * situations may change slightly (and be documented). All those are accompanied
++ * by an entry in doc/APIchanges and incrementing either the minor or micro
++ * version number.

++ * AVBuffer is an API for reference-counted data buffers.
++ *
++ * There are two core objects in this API -- AVBuffer and AVBufferRef. AVBuffer
++ * represents the data buffer itself; it is opaque and not meant to be accessed
++ * by the caller directly, but only through AVBufferRef. However, the caller may
++ * e.g. compare two AVBuffer pointers to check whether two different references
++ * are describing the same data buffer. AVBufferRef represents a single
++ * reference to an AVBuffer and it is the object that may be manipulated by the
++ * caller directly.
++ *
++ * There are two functions provided for creating a new AVBuffer with a single
++ * reference -- av_buffer_alloc() to just allocate a new buffer, and
++ * av_buffer_create() to wrap an existing array in an AVBuffer. From an existing
++ * reference, additional references may be created with av_buffer_ref().
++ * Use av_buffer_unref() to free a reference (this will automatically free the
++ * data once all the references are freed).
++ *
++ * The convention throughout this API and the rest of FFmpeg is such that the
++ * buffer is considered writable if there exists only one reference to it (and
++ * it has not been marked as read-only). The av_buffer_is_writable() function is
++ * provided to check whether this is true and av_buffer_make_writable() will
++ * automatically create a new writable buffer when necessary.
++ * Of course nothing prevents the calling code from violating this convention,
++ * however that is safe only when all the existing references are under its
++ * control.
++ *
++ * @note Referencing and unreferencing the buffers is thread-safe and thus
++ * may be done from multiple threads simultaneously without any need for
++ * additional locking.
++ *
++ * @note Two different references to the same buffer can point to different
++ * parts of the buffer (i.e. their AVBufferRef.data will not be equal).

++ * Utilities to make an array grow when needed.
++ *
++ * Sometimes, the programmer would want to have an array that can grow when

++ *
++ * libavutil supports two systems of appending elements onto a dynamically
++ * allocated array, the first one storing the pointer to the value in the
++ * array, and the second storing the value directly. In both systems, the
++ * caller is responsible for maintaining a variable containing the length of
++ * the array, as well as freeing of the array after use.
++ *
++ * The first system stores pointers to values in a block of dynamically
++ * allocated memory. Since only pointers are stored, the function does not need
++ * to know the size of the type. Both av_dynarray_add() and
++ * av_dynarray_add_nofree() implement this system.
++ *
++ * @code
++ * type **array = NULL; //< an array of pointers to values
++ * int nb = 0; //< a variable to keep track of the length of the array
++ *
++ * type to_be_added = ...;

++ *
++ * - The data layout as used in av_samples_fill_arrays() and elsewhere in FFmpeg

++ *
++ * @par
++ * For planar sample formats, each audio channel is in a separate data plane,
++ * and linesize is the buffer size, in bytes, for a single plane. All data
++ * planes must be the same size. For packed sample formats, only the first data
++ * plane is used, and samples for each channel are interleaved. In this case,

++ GNU LESSER GENERAL PUBLIC LICENSE
++ Version 2.1, February 1999
++
++ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
++ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
++ Everyone is permitted to copy and distribute verbatim copies
++ of this license document, but changing it is not allowed.
++
++[This is the first released version of the Lesser GPL. It also counts
++ as the successor of the GNU Library Public License, version 2, hence
++ the version number 2.1.]
++
++ Preamble
++
++ The licenses for most software are designed to take away your
++freedom to share and change it. By contrast, the GNU General Public
++Licenses are intended to guarantee your freedom to share and change
++free software--to make sure the software is free for all its users.
++
++ This license, the Lesser General Public License, applies to some
++specially designated software packages--typically libraries--of the
++Free Software Foundation and other authors who decide to use it. You
++can use it too, but we suggest you first think carefully about whether
++this license or the ordinary General Public License is the better
++strategy to use in any particular case, based on the explanations below.
++
++ When we speak of free software, we are referring to freedom of use,
++not price. Our General Public Licenses are designed to make sure that
++you have the freedom to distribute copies of free software (and charge
++for this service if you wish); that you receive source code or can get
++it if you want it; that you can change the software and use pieces of
++it in new free programs; and that you are informed that you can do
++these things.
++
++ To protect your rights, we need to make restrictions that forbid
++distributors to deny you these rights or to ask you to surrender these
++rights. These restrictions translate to certain responsibilities for
++you if you distribute copies of the library or if you modify it.
++
++ For example, if you distribute copies of the library, whether gratis
++or for a fee, you must give the recipients all the rights that we gave
++you. You must make sure that they, too, receive or can get the source
++code. If you link other code with the library, you must provide
++complete object files to the recipients, so that they can relink them
++with the library after making changes to the library and recompiling
++it. And you must show them these terms so they know their rights.
++
++ We protect your rights with a two-step method: (1) we copyright the
++library, and (2) we offer you this license, which gives you legal
++permission to copy, distribute and/or modify the library.
++
++ To protect each distributor, we want to make it very clear that
++there is no warranty for the free library. Also, if the library is
++modified by someone else and passed on, the recipients should know
++that what they have is not the original version, so that the original
++author's reputation will not be affected by problems that might be
++introduced by others.
++
++ Finally, software patents pose a constant threat to the existence of
++any free program. We wish to make sure that a company cannot
++effectively restrict the users of a free program by obtaining a
++restrictive license from a patent holder. Therefore, we insist that
++any patent license obtained for a version of the library must be
++consistent with the full freedom of use specified in this license.
++
++ Most GNU software, including some libraries, is covered by the
++ordinary GNU General Public License. This license, the GNU Lesser
++General Public License, applies to certain designated libraries, and
++is quite different from the ordinary General Public License. We use
++this license for certain libraries in order to permit linking those
++libraries into non-free programs.
++
++ When a program is linked with a library, whether statically or using
++a shared library, the combination of the two is legally speaking a
++combined work, a derivative of the original library. The ordinary
++General Public License therefore permits such linking only if the
++entire combination fits its criteria of freedom. The Lesser General
++Public License permits more lax criteria for linking other code with
++the library.
++
++ We call this license the "Lesser" General Public License because it
++does Less to protect the user's freedom than the ordinary General
++Public License. It also provides other free software developers Less
++of an advantage over competing non-free programs. These disadvantages
++are the reason we use the ordinary General Public License for many
++libraries. However, the Lesser license provides advantages in certain
++special circumstances.
++
++ For example, on rare occasions, there may be a special need to
++encourage the widest possible use of a certain library, so that it becomes
++a de-facto standard. To achieve this, non-free programs must be
++allowed to use the library. A more frequent case is that a free
++library does the same job as widely used non-free libraries. In this
++case, there is little to gain by limiting the free library to free
++software only, so we use the Lesser General Public License.
++
++ In other cases, permission to use a particular library in non-free
++programs enables a greater number of people to use a large body of
++free software. For example, permission to use the GNU C Library in
++non-free programs enables many more people to use the whole GNU
++operating system, as well as its variant, the GNU/Linux operating
++system.
++
++ Although the Lesser General Public License is Less protective of the
++users' freedom, it does ensure that the user of a program that is
++linked with the Library has the freedom and the wherewithal to run
++that program using a modified version of the Library.
++
++ The precise terms and conditions for copying, distribution and
++modification follow. Pay close attention to the difference between a
++"work based on the library" and a "work that uses the library". The
++former contains code derived from the library, whereas the latter must
++be combined with the library in order to run.
++
++ GNU LESSER GENERAL PUBLIC LICENSE
++ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
++
++ 0. This License Agreement applies to any software library or other
++program which contains a notice placed by the copyright holder or
++other authorized party saying it may be distributed under the terms of
++this Lesser General Public License (also called "this License").
++Each licensee is addressed as "you".
++
++ A "library" means a collection of software functions and/or data
++prepared so as to be conveniently linked with application programs
++(which use some of those functions and data) to form executables.
++
++ The "Library", below, refers to any such software library or work
++which has been distributed under these terms. A "work based on the
++Library" means either the Library or any derivative work under
++copyright law: that is to say, a work containing the Library or a
++portion of it, either verbatim or with modifications and/or translated
++straightforwardly into another language. (Hereinafter, translation is
++included without limitation in the term "modification".)
++
++ "Source code" for a work means the preferred form of the work for
++making modifications to it. For a library, complete source code means
++all the source code for all modules it contains, plus any associated
++interface definition files, plus the scripts used to control compilation
++and installation of the library.
++
++ Activities other than copying, distribution and modification are not
++covered by this License; they are outside its scope. The act of
++running a program using the Library is not restricted, and output from
++such a program is covered only if its contents constitute a work based
++on the Library (independent of the use of the Library in a tool for
++writing it). Whether that is true depends on what the Library does
++and what the program that uses the Library does.
++
++ 1. You may copy and distribute verbatim copies of the Library's
++complete source code as you receive it, in any medium, provided that
++you conspicuously and appropriately publish on each copy an
++appropriate copyright notice and disclaimer of warranty; keep intact
++all the notices that refer to this License and to the absence of any
++warranty; and distribute a copy of this License along with the
++Library.
++
++ You may charge a fee for the physical act of transferring a copy,
++and you may at your option offer warranty protection in exchange for a
++fee.
++
++ 2. You may modify your copy or copies of the Library or any portion
++of it, thus forming a work based on the Library, and copy and
++distribute such modifications or work under the terms of Section 1
++above, provided that you also meet all of these conditions:
++
++ a) The modified work must itself be a software library.
++
++ b) You must cause the files modified to carry prominent notices
++ stating that you changed the files and the date of any change.
++
++ c) You must cause the whole of the work to be licensed at no
++ charge to all third parties under the terms of this License.
++
++ d) If a facility in the modified Library refers to a function or a
++ table of data to be supplied by an application program that uses
++ the facility, other than as an argument passed when the facility
++ is invoked, then you must make a good faith effort to ensure that,
++ in the event an application does not supply such function or
++ table, the facility still operates, and performs whatever part of
++ its purpose remains meaningful.
++
++ (For example, a function in a library to compute square roots has
++ a purpose that is entirely well-defined independent of the
++ application. Therefore, Subsection 2d requires that any
++ application-supplied function or table used by this function must
++ be optional: if the application does not supply it, the square
++ root function must still compute square roots.)
++
++These requirements apply to the modified work as a whole. If
++identifiable sections of that work are not derived from the Library,
++and can be reasonably considered independent and separate works in
++themselves, then this License, and its terms, do not apply to those
++sections when you distribute them as separate works. But when you
++distribute the same sections as part of a whole which is a work based
++on the Library, the distribution of the whole must be on the terms of
++this License, whose permissions for other licensees extend to the
++entire whole, and thus to each and every part regardless of who wrote
++it.
++
++Thus, it is not the intent of this section to claim rights or contest
++your rights to work written entirely by you; rather, the intent is to
++exercise the right to control the distribution of derivative or
++collective works based on the Library.
++
++In addition, mere aggregation of another work not based on the Library
++with the Library (or with a work based on the Library) on a volume of
++a storage or distribution medium does not bring the other work under
++the scope of this License.
++
++ 3. You may opt to apply the terms of the ordinary GNU General Public
++License instead of this License to a given copy of the Library. To do
++this, you must alter all the notices that refer to this License, so
++that they refer to the ordinary GNU General Public License, version 2,
++instead of to this License. (If a newer version than version 2 of the
++ordinary GNU General Public License has appeared, then you can specify
++that version instead if you wish.) Do not make any other change in
++these notices.
++
++ Once this change is made in a given copy, it is irreversible for
++that copy, so the ordinary GNU General Public License applies to all
++subsequent copies and derivative works made from that copy.
++
++ This option is useful when you wish to copy part of the code of
++the Library into a program that is not a library.
++
++ 4. You may copy and distribute the Library (or a portion or
++derivative of it, under Section 2) in object code or executable form
++under the terms of Sections 1 and 2 above provided that you accompany
++it with the complete corresponding machine-readable source code, which
++must be distributed under the terms of Sections 1 and 2 above on a
++medium customarily used for software interchange.
++
++ If distribution of object code is made by offering access to copy
++from a designated place, then offering equivalent access to copy the
++source code from the same place satisfies the requirement to
++distribute the source code, even though third parties are not
++compelled to copy the source along with the object code.
++
++ 5. A program that contains no derivative of any portion of the
++Library, but is designed to work with the Library by being compiled or
++linked with it, is called a "work that uses the Library". Such a
++work, in isolation, is not a derivative work of the Library, and
++therefore falls outside the scope of this License.
++
++ However, linking a "work that uses the Library" with the Library
++creates an executable that is a derivative of the Library (because it
++contains portions of the Library), rather than a "work that uses the
++library". The executable is therefore covered by this License.
++Section 6 states terms for distribution of such executables.
++
++ When a "work that uses the Library" uses material from a header file
++that is part of the Library, the object code for the work may be a
++derivative work of the Library even though the source code is not.
++Whether this is true is especially significant if the work can be
++linked without the Library, or if the work is itself a library. The
++threshold for this to be true is not precisely defined by law.
++
++ If such an object file uses only numerical parameters, data
++structure layouts and accessors, and small macros and small inline
++functions (ten lines or less in length), then the use of the object
++file is unrestricted, regardless of whether it is legally a derivative
++work. (Executables containing this object code plus portions of the
++Library will still fall under Section 6.)
++
++ Otherwise, if the work is a derivative of the Library, you may
++distribute the object code for the work under the terms of Section 6.
++Any executables containing that work also fall under Section 6,
++whether or not they are linked directly with the Library itself.
++
++ 6. As an exception to the Sections above, you may also combine or
++link a "work that uses the Library" with the Library to produce a
++work containing portions of the Library, and distribute that work
++under terms of your choice, provided that the terms permit
++modification of the work for the customer's own use and reverse
++engineering for debugging such modifications.
++
++ You must give prominent notice with each copy of the work that the
++Library is used in it and that the Library and its use are covered by
++this License. You must supply a copy of this License. If the work
++during execution displays copyright notices, you must include the
++copyright notice for the Library among them, as well as a reference
++directing the user to the copy of this License. Also, you must do one
++of these things:
++
++ a) Accompany the work with the complete corresponding
++ machine-readable source code for the Library including whatever
++ changes were used in the work (which must be distributed under
++ Sections 1 and 2 above); and, if the work is an executable linked
++ with the Library, with the complete machine-readable "work that
++ uses the Library", as object code and/or source code, so that the
++ user can modify the Library and then relink to produce a modified
++ executable containing the modified Library. (It is understood
++ that the user who changes the contents of definitions files in the
++ Library will not necessarily be able to recompile the application
++ to use the modified definitions.)
++
++ b) Use a suitable shared library mechanism for linking with the
++ Library. A suitable mechanism is one that (1) uses at run time a
++ copy of the library already present on the user's computer system,
++ rather than copying library functions into the executable, and (2)
++ will operate properly with a modified version of the library, if
++ the user installs one, as long as the modified version is
++ interface-compatible with the version that the work was made with.
++
++ c) Accompany the work with a written offer, valid for at
++ least three years, to give the same user the materials
++ specified in Subsection 6a, above, for a charge no more
++ than the cost of performing this distribution.
++
++ d) If distribution of the work is made by offering access to copy
++ from a designated place, offer equivalent access to copy the above
++ specified materials from the same place.
++
++ e) Verify that the user has already received a copy of these
++ materials or that you have already sent this user a copy.
++
++ For an executable, the required form of the "work that uses the
++Library" must include any data and utility programs needed for
++reproducing the executable from it. However, as a special exception,
++the materials to be distributed need not include anything that is
++normally distributed (in either source or binary form) with the major
++components (compiler, kernel, and so on) of the operating system on
++which the executable runs, unless that component itself accompanies
++the executable.
++
++ It may happen that this requirement contradicts the license
++restrictions of other proprietary libraries that do not normally
++accompany the operating system. Such a contradiction means you cannot
++use both them and the Library together in an executable that you
++distribute.
++
++ 7. You may place library facilities that are a work based on the
++Library side-by-side in a single library together with other library
++facilities not covered by this License, and distribute such a combined
++library, provided that the separate distribution of the work based on
++the Library and of the other library facilities is otherwise
++permitted, and provided that you do these two things:
++
++ a) Accompany the combined library with a copy of the same work
++ based on the Library, uncombined with any other library
++ facilities. This must be distributed under the terms of the
++ Sections above.
++
++ b) Give prominent notice with the combined library of the fact
++ that part of it is a work based on the Library, and explaining
++ where to find the accompanying uncombined form of the same work.
++
++ 8. You may not copy, modify, sublicense, link with, or distribute
++the Library except as expressly provided under this License. Any
++attempt otherwise to copy, modify, sublicense, link with, or
++distribute the Library is void, and will automatically terminate your
++rights under this License. However, parties who have received copies,
++or rights, from you under this License will not have their licenses
++terminated so long as such parties remain in full compliance.
++
++ 9. You are not required to accept this License, since you have not
++signed it. However, nothing else grants you permission to modify or
++distribute the Library or its derivative works. These actions are
++prohibited by law if you do not accept this License. Therefore, by
++modifying or distributing the Library (or any work based on the
++Library), you indicate your acceptance of this License to do so, and
++all its terms and conditions for copying, distributing or modifying
++the Library or works based on it.
++
++ 10. Each time you redistribute the Library (or any work based on the
++Library), the recipient automatically receives a license from the
++original licensor to copy, distribute, link with or modify the Library
++subject to these terms and conditions. You may not impose any further
++restrictions on the recipients' exercise of the rights granted herein.
++You are not responsible for enforcing compliance by third parties with
++this License.
++
++ 11. If, as a consequence of a court judgment or allegation of patent
++infringement or for any other reason (not limited to patent issues),
++conditions are imposed on you (whether by court order, agreement or
++otherwise) that contradict the conditions of this License, they do not
++excuse you from the conditions of this License. If you cannot
++distribute so as to satisfy simultaneously your obligations under this
++License and any other pertinent obligations, then as a consequence you
++may not distribute the Library at all. For example, if a patent
++license would not permit royalty-free redistribution of the Library by
++all those who receive copies directly or indirectly through you, then
++the only way you could satisfy both it and this License would be to
++refrain entirely from distribution of the Library.
++
++If any portion of this section is held invalid or unenforceable under any
++particular circumstance, the balance of the section is intended to apply,
++and the section as a whole is intended to apply in other circumstances.
++
++It is not the purpose of this section to induce you to infringe any
++patents or other property right claims or to contest validity of any
++such claims; this section has the sole purpose of protecting the
++integrity of the free software distribution system which is
++implemented by public license practices. Many people have made
++generous contributions to the wide range of software distributed
++through that system in reliance on consistent application of that
++system; it is up to the author/donor to decide if he or she is willing
++to distribute software through any other system and a licensee cannot
++impose that choice.
++
++This section is intended to make thoroughly clear what is believed to
++be a consequence of the rest of this License.
++
++ 12. If the distribution and/or use of the Library is restricted in
++certain countries either by patents or by copyrighted interfaces, the
++original copyright holder who places the Library under this License may add
++an explicit geographical distribution limitation excluding those countries,
++so that distribution is permitted only in or among countries not thus
++excluded. In such case, this License incorporates the limitation as if
++written in the body of this License.
++
++ 13. The Free Software Foundation may publish revised and/or new
++versions of the Lesser General Public License from time to time.
++Such new versions will be similar in spirit to the present version,
++but may differ in detail to address new problems or concerns.
++
++Each version is given a distinguishing version number. If the Library
++specifies a version number of this License which applies to it and
++"any later version", you have the option of following the terms and
++conditions either of that version or of any later version published by
++the Free Software Foundation. If the Library does not specify a
++license version number, you may choose any version ever published by
++the Free Software Foundation.
++
++ 14. If you wish to incorporate parts of the Library into other free
++programs whose distribution conditions are incompatible with these,
++write to the author to ask for permission. For software which is
++copyrighted by the Free Software Foundation, write to the Free
++Software Foundation; we sometimes make exceptions for this. Our
++decision will be guided by the two goals of preserving the free status
++of all derivatives of our free software and of promoting the sharing
++and reuse of software generally.
++
++ NO WARRANTY
++
++ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
++WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
++EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
++OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
++KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
++IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
++PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
++LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
++THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
++
++ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
++WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
++AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
++FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
++CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
++LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
++RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
++FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
++SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
++DAMAGES.
++
++ END OF TERMS AND CONDITIONS
++
++ How to Apply These Terms to Your New Libraries
++
++ If you develop a new library, and you want it to be of the greatest
++possible use to the public, we recommend making it free software that
++everyone can redistribute and change. You can do so by permitting
++redistribution under these terms (or, alternatively, under the terms of the
++ordinary General Public License).
++
++ To apply these terms, attach the following notices to the library. It is
++safest to attach them to the start of each source file to most effectively
++convey the exclusion of warranty; and each file should have at least the
++"copyright" line and a pointer to where the full notice is found.
++
++ <one line to give the library's name and a brief idea of what it does.>
++ Copyright (C) <year> <name of author>
++

++Also add information on how to contact you by electronic and paper mail.

++ * @{
++ *
++ * The avcodec_send_packet()/avcodec_receive_frame()/avcodec_send_frame()/
++ * avcodec_receive_packet() functions provide an encode/decode API, which
++ * decouples input and output.
++ *
++ * The API is very similar for encoding/decoding and audio/video, and works as
++ * follows:
++ * - Set up and open the AVCodecContext as usual.
++ * - Send valid input:
++ * - For decoding, call avcodec_send_packet() to give the decoder raw
++ * compressed data in an AVPacket.
++ * - For encoding, call avcodec_send_frame() to give the encoder an AVFrame
++ * containing uncompressed audio or video.
++ * In both cases, it is recommended that AVPackets and AVFrames are
++ * refcounted, or libavcodec might have to copy the input data. (libavformat
++ * always returns refcounted AVPackets, and av_frame_get_buffer() allocates
++ * refcounted AVFrames.)
++ * - Receive output in a loop. Periodically call one of the avcodec_receive_*()
++ * functions and process their output:
++ * - For decoding, call avcodec_receive_frame(). On success, it will return
++ * an AVFrame containing uncompressed audio or video data.
++ * - For encoding, call avcodec_receive_packet(). On success, it will return
++ * an AVPacket with a compressed frame.
++ * Repeat this call until it returns AVERROR(EAGAIN) or an error. The
++ * AVERROR(EAGAIN) return value means that new input data is required to
++ * return new output. In this case, continue with sending input. For each
++ * input frame/packet, the codec will typically return 1 output frame/packet,
++ * but it can also be 0 or more than 1.
++ *
++ * At the beginning of decoding or encoding, the codec might accept multiple
++ * input frames/packets without returning a frame, until its internal buffers
++ * are filled. This situation is handled transparently if you follow the steps
++ * outlined above.
++ *
++ * In theory, sending input can result in EAGAIN - this should happen only if
++ * not all output was received. You can use this to structure alternative decode
++ * or encode loops other than the one suggested above. For example, you could
++ * try sending new input on each iteration, and try to receive output if that
++ * returns EAGAIN.
++ *
++ * End of stream situations. These require "flushing" (aka draining) the codec,
++ * as the codec might buffer multiple frames or packets internally for
++ * performance or out of necessity (consider B-frames).
++ * This is handled as follows:
++ * - Instead of valid input, send NULL to the avcodec_send_packet() (decoding)
++ * or avcodec_send_frame() (encoding) functions. This will enter draining
++ * mode.
++ * - Call avcodec_receive_frame() (decoding) or avcodec_receive_packet()
++ * (encoding) in a loop until AVERROR_EOF is returned. The functions will
++ * not return AVERROR(EAGAIN), unless you forgot to enter draining mode.
++ * - Before decoding can be resumed again, the codec has to be reset with
++ * avcodec_flush_buffers().
++ *
++ * Using the API as outlined above is highly recommended. But it is also
++ * possible to call functions outside of this rigid schema. For example, you can
++ * call avcodec_send_packet() repeatedly without calling
++ * avcodec_receive_frame(). In this case, avcodec_send_packet() will succeed
++ * until the codec's internal buffer has been filled up (which is typically of
++ * size 1 per output frame, after initial input), and then reject input with
++ * AVERROR(EAGAIN). Once it starts rejecting input, you have no choice but to
++ * read at least some output.
++ *
++ * Not all codecs will follow a rigid and predictable dataflow; the only
++ * guarantee is that an AVERROR(EAGAIN) return value on a send/receive call on
++ * one end implies that a receive/send call on the other end will succeed, or
++ * at least will not fail with AVERROR(EAGAIN). In general, no codec will
++ * permit unlimited buffering of input or output.
++ *
++ * This API replaces the following legacy functions:
++ * - avcodec_decode_video2() and avcodec_decode_audio4():
++ * Use avcodec_send_packet() to feed input to the decoder, then use
++ * avcodec_receive_frame() to receive decoded frames after each packet.
++ * Unlike with the old video decoding API, multiple frames might result from
++ * a packet. For audio, splitting the input packet into frames by partially
++ * decoding packets becomes transparent to the API user. You never need to
++ * feed an AVPacket to the API twice (unless it is rejected with AVERROR(EAGAIN) - then
++ * no data was read from the packet).
++ * Additionally, sending a flush/draining packet is required only once.
++ * - avcodec_encode_video2()/avcodec_encode_audio2():
++ * Use avcodec_send_frame() to feed input to the encoder, then use
++ * avcodec_receive_packet() to receive encoded packets.
++ * Providing user-allocated buffers for avcodec_receive_packet() is not
++ * possible.
++ * - The new API does not handle subtitles yet.
++ *
++ * Mixing new and old function calls on the same AVCodecContext is not allowed,
++ * and will result in undefined behavior.
++ *
++ * Some codecs might require using the new API; using the old API will return
++ * an error when calling it. All codecs support the new API.
++ *
++ * A codec is not allowed to return AVERROR(EAGAIN) for both sending and receiving. This
++ * would be an invalid state, which could put the codec user into an endless
++ * loop. The API has no concept of time either: it cannot happen that trying to
++ * do avcodec_send_packet() results in AVERROR(EAGAIN), but a repeated call 1 second
++ * later accepts the packet (with no other receive/flush API calls involved).
++ * The API is a strict state machine, and the passage of time is not supposed
++ * to influence it. Some timing-dependent behavior might still be deemed
++ * acceptable in certain cases. But it must never result in both send/receive
++ * returning EAGAIN at the same time at any point. It must also absolutely be
++ * avoided that the current state is "unstable" and can "flip-flop" between
++ * the send/receive APIs allowing progress. For example, it's not allowed that
++ * the codec randomly decides that it actually wants to consume a packet now
++ * instead of returning a frame, after it just returned AVERROR(EAGAIN) on an
++ * avcodec_send_packet() call.

++ * This callback is called at the beginning of each frame to get data
++ * buffer(s) for it. There may be one contiguous buffer for all the data or
++ * there may be a buffer per each data plane or anything in between. What
++ * this means is, you may set however many entries in buf[] you feel necessary.
++ * Each buffer must be reference-counted using the AVBuffer API (see description
++ * of buf[] below).
++ *
++ * The following fields will be set in the frame before this callback is
++ * called:
++ * - format
++ * - width, height (video only)
++ * - sample_rate, channel_layout, nb_samples (audio only)
++ * Their values may differ from the corresponding values in
++ * AVCodecContext. This callback must use the frame values, not the codec
++ * context values, to calculate the required buffer size.
++ *
++ * This callback must fill the following fields in the frame:
++ * - data[]
++ * - linesize[]
++ * - extended_data:
++ * * if the data is planar audio with more than 8 channels, then this
++ * callback must allocate and fill extended_data to contain all pointers
++ * to all data planes. data[] must hold as many pointers as it can.
++ * extended_data must be allocated with av_malloc() and will be freed in
++ * av_frame_unref().
++ * * otherwise extended_data must point to data
++ * - buf[] must contain one or more pointers to AVBufferRef structures. Each of
++ * the frame's data and extended_data pointers must be contained in these. That
++ * is, one AVBufferRef for each allocated chunk of memory, not necessarily one
++ * AVBufferRef per data[] entry. See: av_buffer_create(), av_buffer_alloc(),
++ * and av_buffer_ref().
++ * - extended_buf and nb_extended_buf must be allocated with av_malloc() by
++ * this callback and filled with the extra buffers if there are more
++ * buffers than buf[] can hold. extended_buf will be freed in
++ * av_frame_unref().
++ *
++ * If AV_CODEC_CAP_DR1 is not set then get_buffer2() must call
++ * avcodec_default_get_buffer2() instead of providing buffers allocated by
++ * some other means.
++ *
++ * Each data plane must be aligned to the maximum required by the target
++ * CPU.
++ *
++ * @see avcodec_default_get_buffer2()
++ *
++ * Video:
++ *
++ * If AV_GET_BUFFER_FLAG_REF is set in flags then the frame may be reused
++ * (read and/or written to if it is writable) later by libavcodec.
++ *
++ * avcodec_align_dimensions2() should be used to find the required width and
++ * height, as they normally need to be rounded up to the next multiple of 16.
++ *
++ * Some decoders do not support linesizes changing between frames.
++ *
++ * If frame multithreading is used and thread_safe_callbacks is set,
++ * this callback may be called from a different thread, but not from more
++ * than one at once. Does not need to be reentrant.
++ *
++ * @see avcodec_align_dimensions2()
++ *
++ * Audio:
++ *
++ * Decoders request a buffer of a particular size by setting
++ * AVFrame.nb_samples prior to calling get_buffer2(). The decoder may,
++ * however, utilize only part of the buffer by setting AVFrame.nb_samples
++ * to a smaller value in the output frame.
++ *
++ * As a convenience, av_samples_get_buffer_size() and
++ * av_samples_fill_arrays() in libavutil may be used by custom get_buffer2()
++ * functions to find the required data size and to fill data pointers and
++ * linesize. In AVFrame.linesize, only linesize[0] may be set for audio
++ * since all planes must be the same size.
++ *
++ * @see av_samples_get_buffer_size(), av_samples_fill_arrays()

++ * Create and return a AVHWFramesContext with values adequate for hardware
++ * decoding. This is meant to get called from the get_format callback, and is
++ * a helper for preparing a AVHWFramesContext for AVCodecContext.hw_frames_ctx.
++ * This API is for decoding with certain hardware acceleration modes/APIs only.
++ *
++ * The returned AVHWFramesContext is not initialized. The caller must do this
++ * with av_hwframe_ctx_init().
++ *
++ * Calling this function is not a requirement, but makes it simpler to avoid
++ * codec or hardware API specific details when manually allocating frames.
++ *
++ * Alternatively to this, an API user can set AVCodecContext.hw_device_ctx,
++ * which sets up AVCodecContext.hw_frames_ctx fully automatically, and makes
++ * it unnecessary to call this function or having to care about
++ * AVHWFramesContext initialization at all.
++ *
++ * There are a number of requirements for calling this function:
++ *
++ * - It must be called from get_format with the same avctx parameter that was
++ * passed to get_format. Calling it outside of get_format is not allowed, and
++ * can trigger undefined behavior.
++ * - The function is not always supported (see description of return values).
++ * Even if this function returns successfully, hwaccel initialization could
++ * fail later. (The degree to which implementations check whether the stream
++ * is actually supported varies. Some do this check only after the user's
++ * get_format callback returns.)
++ * - The hw_pix_fmt must be one of the choices suggested by get_format. If the
++ * user decides to use a AVHWFramesContext prepared with this API function,
++ * the user must return the same hw_pix_fmt from get_format.
++ * - The device_ref passed to this function must support the given hw_pix_fmt.
++ * - After calling this API function, it is the user's responsibility to
++ * initialize the AVHWFramesContext (returned by the out_frames_ref parameter),
++ * and to set AVCodecContext.hw_frames_ctx to it. If done, this must be done
++ * before returning from get_format (this is implied by the normal
++ * AVCodecContext.hw_frames_ctx API rules).
++ * - The AVHWFramesContext parameters may change every time time get_format is
++ * called. Also, AVCodecContext.hw_frames_ctx is reset before get_format. So
++ * you are inherently required to go through this process again on every
++ * get_format call.
++ * - It is perfectly possible to call this function without actually using
++ * the resulting AVHWFramesContext. One use-case might be trying to reuse a
++ * previously initialized AVHWFramesContext, and calling this API function
++ * only to test whether the required frame parameters have changed.
++ * - Fields that use dynamically allocated values of any kind must not be set
++ * by the user unless setting them is explicitly allowed by the documentation.
++ * If the user sets AVHWFramesContext.free and AVHWFramesContext.user_opaque,
++ * the new free callback must call the potentially set previous free callback.
++ * This API call may set any dynamically allocated fields, including the free
++ * callback.
++ *
++ * The function will set at least the following fields on AVHWFramesContext
++ * (potentially more, depending on hwaccel API):
++ *
++ * - All fields set by av_hwframe_ctx_alloc().
++ * - Set the format field to hw_pix_fmt.
++ * - Set the sw_format field to the most suited and most versatile format. (An
++ * implication is that this will prefer generic formats over opaque formats
++ * with arbitrary restrictions, if possible.)
++ * - Set the width/height fields to the coded frame size, rounded up to the
++ * API-specific minimum alignment.
++ * - Only _if_ the hwaccel requires a pre-allocated pool: set the initial_pool_size
++ * field to the number of maximum reference surfaces possible with the codec,
++ * plus 1 surface for the user to work (meaning the user can safely reference
++ * at most 1 decoded surface at a time), plus additional buffering introduced
++ * by frame threading. If the hwaccel does not require pre-allocation, the
++ * field is left to 0, and the decoder will allocate new surfaces on demand
++ * during decoding.
++ * - Possibly AVHWFramesContext.hwctx fields, depending on the underlying
++ * hardware API.
++ *
++ * Essentially, out_frames_ref returns the same as av_hwframe_ctx_alloc(), but
++ * with basic frame parameters set.
++ *
++ * The function is stateless, and does not change the AVCodecContext or the
++ * device_ref AVHWDeviceContext.
++ *
++ * @param avctx The context which is currently calling get_format, and which
++ * implicitly contains all state needed for filling the returned
++ * AVHWFramesContext properly.
++ * @param device_ref A reference to the AVHWDeviceContext describing the device
++ * which will be used by the hardware decoder.
++ * @param hw_pix_fmt The hwaccel format you are going to return from get_format.

++ * AVERROR(ENOENT): the decoder does not support this functionality. Setup
++ * is always manual, or it is a decoder which does not
++ * support setting AVCodecContext.hw_frames_ctx at all,
++ * or it is a software format.
++ * AVERROR(EINVAL): it is known that hardware decoding is not supported for
++ * this configuration, or the device_ref is not supported
++ * for the hwaccel referenced by hw_pix_fmt.

++ * @section ffmpeg_intro Introduction
++ *
++ * This document describes the usage of the different libraries
++ * provided by FFmpeg.
++ *
++ * @li @ref libavc "libavcodec" encoding/decoding library
++ * @li @ref lavfi "libavfilter" graph-based frame editing library
++ * @li @ref libavf "libavformat" I/O and muxing/demuxing library
++ * @li @ref lavd "libavdevice" special devices muxing/demuxing library
++ * @li @ref lavu "libavutil" common utility library
++ * @li @ref lswr "libswresample" audio resampling, format conversion and mixing
++ * @li @ref lpp "libpostproc" post processing library
++ * @li @ref libsws "libswscale" color conversion and scaling library
++ *
++ * @section ffmpeg_versioning Versioning and compatibility
++ *
++ * Each of the FFmpeg libraries contains a version.h header, which defines a
++ * major, minor and micro version number with the
++ * <em>LIBRARYNAME_VERSION_{MAJOR,MINOR,MICRO}</em> macros. The major version
++ * number is incremented with backward incompatible changes - e.g. removing
++ * parts of the public API, reordering public struct members, etc. The minor
++ * version number is incremented for backward compatible API changes or major
++ * new features - e.g. adding a new public function or a new decoder. The micro
++ * version number is incremented for smaller changes that a calling program
++ * might still want to check for - e.g. changing behavior in a previously
++ * unspecified situation.
++ *
++ * FFmpeg guarantees backward API and ABI compatibility for each library as long
++ * as its major version number is unchanged. This means that no public symbols
++ * will be removed or renamed. Types and names of the public struct members and
++ * values of public macros and enums will remain the same (unless they were
++ * explicitly declared as not part of the public API). Documented behavior will
++ * not change.
++ *
++ * In other words, any correct program that works with a given FFmpeg snapshot
++ * should work just as well without any changes with any later snapshot with the
++ * same major versions. This applies to both rebuilding the program against new
++ * FFmpeg versions or to replacing the dynamic FFmpeg libraries that a program
++ * links against.
++ *
++ * However, new public symbols may be added and new members may be appended to
++ * public structs whose size is not part of public ABI (most public structs in
++ * FFmpeg). New macros and enum values may be added. Behavior in undocumented
++ * situations may change slightly (and be documented). All those are accompanied
++ * by an entry in doc/APIchanges and incrementing either the minor or micro
++ * version number.

++ * @{
++ * AVBuffer is an API for reference-counted data buffers.
++ *
++ * There are two core objects in this API -- AVBuffer and AVBufferRef. AVBuffer
++ * represents the data buffer itself; it is opaque and not meant to be accessed
++ * by the caller directly, but only through AVBufferRef. However, the caller may
++ * e.g. compare two AVBuffer pointers to check whether two different references
++ * are describing the same data buffer. AVBufferRef represents a single
++ * reference to an AVBuffer and it is the object that may be manipulated by the
++ * caller directly.
++ *
++ * There are two functions provided for creating a new AVBuffer with a single
++ * reference -- av_buffer_alloc() to just allocate a new buffer, and
++ * av_buffer_create() to wrap an existing array in an AVBuffer. From an existing
++ * reference, additional references may be created with av_buffer_ref().
++ * Use av_buffer_unref() to free a reference (this will automatically free the
++ * data once all the references are freed).
++ *
++ * The convention throughout this API and the rest of FFmpeg is such that the
++ * buffer is considered writable if there exists only one reference to it (and
++ * it has not been marked as read-only). The av_buffer_is_writable() function is
++ * provided to check whether this is true and av_buffer_make_writable() will
++ * automatically create a new writable buffer when necessary.
++ * Of course nothing prevents the calling code from violating this convention,
++ * however that is safe only when all the existing references are under its
++ * control.
++ *
++ * @note Referencing and unreferencing the buffers is thread-safe and thus
++ * may be done from multiple threads simultaneously without any need for
++ * additional locking.
++ *
++ * @note Two different references to the same buffer can point to different
++ * parts of the buffer (i.e. their AVBufferRef.data will not be equal).

++ *
++ * At the beginning, the user must call av_buffer_pool_init() to create the

++ * and all its contents.

++ * Utilities to make an array grow when needed.
++ *
++ * Sometimes, the programmer would want to have an array that can grow when
++ * needed. The libavutil dynamic array utilities fill that need.
++ *
++ * libavutil supports two systems of appending elements onto a dynamically
++ * allocated array, the first one storing the pointer to the value in the
++ * array, and the second storing the value directly. In both systems, the
++ * caller is responsible for maintaining a variable containing the length of
++ * the array, as well as freeing of the array after use.
++ *
++ * The first system stores pointers to values in a block of dynamically
++ * allocated memory. Since only pointers are stored, the function does not need
++ * to know the size of the type. Both av_dynarray_add() and
++ * av_dynarray_add_nofree() implement this system.
++ *
++ * @code
++ * type **array = NULL; //< an array of pointers to values
++ * int nb = 0; //< a variable to keep track of the length of the array
++ *
++ * type to_be_added = ...;

++ * @endcode
++ *
++ * The second system stores the value directly in a block of memory. As a
++ * result, the function has to know the size of the type. av_dynarray2_add()
