[BUG] -vf screenshot breaks -vo md5sum
Running the following command: $ mplayer file.avi -nosound -benchmark -vf screenshot -vo md5sum Results in -vo md5sum reporting the same md5sum for every frame: $ cat md5sums 945032168942b41ae9210d5c4f8fe5c8 frame00000000 945032168942b41ae9210d5c4f8fe5c8 frame00000001 945032168942b41ae9210d5c4f8fe5c8 frame00000002 945032168942b41ae9210d5c4f8fe5c8 frame00000003 945032168942b41ae9210d5c4f8fe5c8 frame00000004 945032168942b41ae9210d5c4f8fe5c8 frame00000005 .... The md5sums aren't always the same for different movies; it seems they vary based on resolution. I've tested this on amd64 and i386 with current CVS mplayer, so I'm fairly confident it isn't a problem on my part. Let me know if I'm being too lazy and you can't reproduce it. :) A verbose log is attached. -Corey

Maybe send Jindrich a mail directly, I'm not sure he is on this mailing list... Diego
