[MPlayer-users] Notes on MPlayer codecs

[Arpi]

Hi,

> I recently upgraded from MPlayer-0.90pre8 to MPlayer-0.90rc2. Here are some
> notices of differences between the versions and more:
> 
> 1)
> MPlayer-0.90rc2 can not decode AVIs encoded with Mencoder-0.90pre8 using
> options "-lavcopts vcodec=rv10 -ovc lavc" and vice versa. Looks like the
> rv10 codec in libavcodec is incompatible between the two versions.

yes. actually it's a bug fixed...
anyway encoding to .avi using rv10 is a generaly bad idea.
anyway encoding to rv10 in general is a bad idea too.

> 2)
> MPlayer-0.90rc2 is able to decode AVIs encoded with the open source
> OpenDIVX using libavcodec, the older version wasn't. Great work!
:)

> 3) However, "mencoder -vc ffodivx -ovc rawrgb" doesn't work even if
> mplayer with -vc ffodivx does work. This is surprising: ffodivx
> works with mplayer but not with mencoder.

ffodivx cannot out in RGB, add -vop scale

> 4) MPEG video decoded with "-vc mpeg12" skips two first frames on my tests,
> with "-vc ffmpeg12" it is ok. Not fatal, but makes one wondering
> when using something like "-vo yuv4mpeg".

new libmpeg2 will solve this, it' sjust not commite dyet (experimental code)
