[MPlayer-users] Having trouble producing mpeg from mov

[Philip Walden]

I am trying to convert some mov files with no audio to mpeg for better 
compression.

When do:

 mencoder -of mpeg -ovc lavc -lavcopts vcodec=msmpeg4v2 -o PC290052.mpg 
PC290052.MOV

and try mplayer to see the result I get:

Playing PC290052.mpg.
Win32 LoadLibrary failed to load: avisynth.dll, 
/usr/lib/win32/avisynth.dll, /usr/local/lib/win32/avisynth.dll
MPEG: Missing video stream!? Contact the author, it may be a bug :(
libavformat file format detected.
LAVF: no audio or video headers found - broken file?

When I drop the "-of mpeg" option (which I understand now creates an avi 
container) the result can be played back with mplayer. [In addition I 
can real player, window media player to play it, but quicktime lock up! 
separate issue]

What am I doing wrong?

Below is the mencoder log with the "-of mpeg" option that appears to 
cause the problem.
