[MPlayer-users] seeking to frame and pausing

[Ricardo Kleemann]

Thanks...

What if I wanted to instead take snapshots of frames? I know I can do -vo jpeg 
but that just keeps on playing and rendering jpegs from the frames.

Is there a way I can use -ss <time> and specify to say, only play 5 seconds, 
thus generating jpegs for that time frame?

I'm just trying to compare the encoding output of different parameters, I 
wanted to compare frames...
