[MPlayer-users] Screenshot from specific frame number

[Marlon Smith]

Hi Onur, thanks for the quick reply.  I've been doing this to get a
screenshot from an avi video file:

mplayer input_file.avi -nosound -ss 00:00:10 -vo png -frames 1

and it does exactly what I want.  It just doesn't work for raw h.264
files since I can't seek to a time location.  In the example above, I'd
love to just replace the 00:00:10 with frame #300, but mplayer doesn't
seem to give me that option.
