[MPlayer-users] video runs too fast when convert rmvb to yuv4mpeg

[姜孝慈]

Hi,

I am trying to uncompress rmvb video via this command:

 mplayer anime.rmvb -vo yuv4mpeg:file=anime.yuv -ao null -nosound \
 -noframedrop -quiet -identify

and the output video goes too fast. (I can play rmvb file correctly
with mplayer)
After convert, a 25 minute video become 17 minute.
When I use this command to convert flv to yuv, it work fine.
-autosync 1 and -mc 0 does not help.

mencoder has this problem too. Here is my mencoder command:

  mencoder anime.rmvb -endpos 00:00:30 \
  -o anime.yuv -ovc raw -vf format=yv12 -nosound -noskip -mc 0 -autosync 1

Here is mplayer output:
