OT: Rejoining video files

[david walcroft]

Hi,
    Can someone tell me how to rejoin .mpeg/.avi/.mov/.wmv type files,
I have some from a local binaries usenet and to post they split them
up some are 6 sections and have an .eml added,the majority use M$ to OP.
  I'm using fc2 and mplayer but know nothing of video.

Thanks   david

Use tmpgenc.

I used to use a simple script called uustrip.  That was 10-15 years ago. 
  I haven't found any updated version of it in a while.  It is basically 
a wrapper for uudecode to strip out the header info from the various 
postings leaving only the uuencoded part which it then sent to uudecode. 
  No support for newer encoding methods (xxencode or rar or such).

I also used to use AUB (Assemble Usenet Binaries) which would read files 
directly from various NewsGroups via nntp and decode the contents of all 
of the fragmented files which were comepletly available....  It was 
written entirely in Perl, and did the decoding itself.  It did its best 
to find all of the partial files by sorting through the Subject lines 
and grouping based the part numbers.  Again, my copy is old enough to 
not support other than uuencoded binaries.

I've often wished that some of the (current) Newsreaders had better 
support for grouping/saving/decoding split postings.  XRn used to do it 
real well 15 years ago....  Mozilla/Thunderbird won't even let you save 
multiple postings to a single file!

Thanks kevin,
   Managed to get back into sorting out the binaries after a hard bout 
with bi-polar,I found the perl prog. aub at freshmeat and a rpm at 
rpmfind ver.2.1.3-1.i686 but is two years old and does not appear to be 
maintained anymore,it handled all the various .ext's but I forgot the -c
option first up.

--- 108 images -- bigpond.broadband.binaries -> /home/david/kinema
----- all done -- bigpond.broadband.binaries
  -- Extracted Files: 108, Total Time Taken: 499 secs
  -- Thrown away files: 19 (not encoded, or illegal suffix, or duplicate)
  -- Total Extracted: 344413.1 KBytes
  -- Total Downloaded: 507750.6 KBytes
  -- Rate of downloading (includes decode time): 1017.5 KBytes/sec

I ran a few .wmv's and appear to be very good (no jerks at a joining 
point - not that I would notice! )

Thanks for the help   david

This might not work since I don't know the internal .mpeg or .avi or
whatever format but why don't you try:

cat $mpeg1 $mpeg2 > $megaMPEG

and see what happens?

This works fine for mpeg files but not avi (though given that AVI is
more a wrapper than a codec, I might be wrong there.  Any way I used
this often for mpg and has always worked.  Only used once for .avi with
no result, never tried .mov etc.

Let me understand clearly.

You are downloading a multipart binary from Usenet.  You get something 
like yyy.avi.001 yyy.avi.002 yyy.avi.003 in your saved directory, 
correct? (I was going to use xxx but I thought that was suggesting 
something.) ;)

Now if this is correct, then all you have to do is cat them together. 
  I have done this for years.  Now to compound things, I have found 
that  if and .avi file is missing a segment, and it of some certain 
formats, it won't play past the missing segment.  I have run across 
the same problem with .wmv files.  I wrote a simple script but it 
won't work with files that have spaces in their names.

Now if you look at the instructions for mencoder, there is a method 
that will join avi segments and process the index.  It works 
sometimes.  I did have a command that would repair avi's and process 
avi segments using mencoder but I lost it during the xmas cleanup.  I 
shouldn't have relied on a sticky note to stay around.

Also if you have a problem with a file, using mplayer -idx filename 
sometimes helps as well.

Mplayer is a nice tool but I found that avifile that was on RH 6 was 
great as it would play almost any segment of a file which I cannot get 
mplayer to do.  It could have something to do with the codec of the avi.

Look at the mplayer/mencoder documentation.

Thanks everybody,
       I think it will take a couple of days to work through all the info
so I'll post any results (if I get any )
