[MPlayer-users] libavcodec - encoding with bframes

[Michal Seliga]

I uploaded testfile&outputs to ftp.mplayerhq.hu/MPlayer/incoming/,
find file named:

libavcodec-broken_divx_encoding_with_bframes.tar.bz2 

complete bugreport included in archive

Mplayer is CVS version from 4.6.2002
libavcodec is CVS version from 4.6.2002
Mandrake 8.2
gcc 3.0.4

problem: when I compress test.mpg with libavcodec to divx with no B frames it looks 
good. If I use B frames there is green stripe at the left side of image. It always 
worked well with mplayer version 0.90pre4 and libavcodec included in its archive...

btw. is it possible to generate divx video stream with B frames compatible with 
windows divx? Because almost everyone has divx5 installed and it is hard to 
persuade people to install ffdshow codecs... (Once I got reply that divx5 is buggy but 
maybe it is possible to workaround its bugs somehow...).

And if divx video stream has B frames, shouldn't it have DX50 code in avi?

And can someone tell me what does this strange divx features mean, what is their 
advantages (speed, size, quality...) and if they are supported by libavcodec (both 
encodeing and decoding)? I mean Quarter Pixel and GMC.
