Hi,

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

:)

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

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