Summary     : Wrapper library for the Video Decode and Presentation API
Description :

It provides an interface to video decode acceleration and presentation
hardware present in modern GPUs.

Update Information:

This version of libvdpau includes workarounds for two bugs in the Adobe® Flash®
Player:

 * Flash swaps the Cb and Cr arguments when it calls
   VdpVideoSurfacePutBitsYCbCr.  This generally makes videos that use this
   method of uploading images have a slightly bluish tinge, especially on skin
   tones.

   The workaround simply swaps the Cb and Cr arguments to this function.

   This workaround is applied if "libflashplayer" is found in /proc/self/cmdline
   and the string "enable_flash_uv_swap=1" is found in /etc/vdpau_wrapper.cfg.

 * Even though it does not depend on a specific color key color, Flash sets the
   color to pure black or pure white, which causes video to bleed through into
   other windows when those colors are used.

   The workaround simply ignores requests to change the color key value.

   This workaround is applied if "libflashplayer" is found in /proc/self/cmdline
   and the string "disable_flash_pq_bg_color=1" is found in
   /etc/vdpau_wrapper.cfg.

This release also contains a fix for a memory leak that occurs hen libvdpau is unloaded.
