[MEncoder-users] sstep issues with mplayer/mencoder

[Grozdan Nikolov]

Hi,

I have a MP4 file which contains 2 video streams in it. When I try to get the 
crop values with the cropdetect filter for the first video stream and when I 
use the -sstep option, it works just fine, eg

mplayer file.mp4 -vid 0 -vf cropdetect -vo null -nosound -frames 15 -sstep 
$((6888/15))

When I do the same for the second stream by only changing -vid 0 to -vid 1, 
mplayer doesn't print any crop value. However, when I remove the -sstep 
option, it prints the crop values just fine. Anyone knows what's going on?

Thanks in advance
