[MPlayer-users] -rawvideo size option does not work.

[Bill Crockett]

With  the -rawvideo options, the last one listed is size:

size=<value>

          frame size in Bytes

mplayer -rawvideo fps=25:w=768:h=576:yv12:size=31754 -demuxer rawvideo 
somevideo.yuv

Putting in a "size=31754" option, this is displayed:

Frame too small! <31754<663552> Wrong format?

How do you calculate the frame size in Bytes please?  I thought it means 
the files size divided by the number of frames.
