Yes, I want to run mplayer inside octave.
MPlayer works successfully when I execute it just to read a video 
stream, ie when I type
"C:\Program Files\MPlayer\mplayer.exe"  myfile.avi
on a DOS prompt, but if I try to extract frames by typing
"C:\Program Files\MPlayer\mplayer.exe" -vo png  myfile.avi
I get the same error message as with the octave script.
