[MPlayer-users] mencoder MJPEGS won't play in WMP

Hi all, Sorry if this is a FAQ, or something obvious I've missed - I've looked for the answer on the web. I have some MJPEG video, PCM audio AVI files that came from my digital camera (a Canon Powershot A40) and I wish to rotate them, so people can view them without turning their head through 90 degrees. I did this: mencoder -vop rotate=1 -ovc lavc -lavcopts vcodec=mjpeg -oac copy source.avi -o dest.avi MPlayer can play the rotated files, but Windows Media Player cannot - there is only sound without video. WMP can play the orginal files from my digicam fine. Anyone know why, or how to fix it? Thanks G -- Navigare necesse est -- Gnaeus Pompeius
