[MPlayer-users] Problems Using Mencoder

[Sean Zimmermann]

Hello,

I downloaded and compiled today's CVS snapshot on my Mac running  
Tiger (10.4.1) with gcc 4.0, and although mplayer seems to be working  
fine, mencoder does not appear to be working. Whenever I use  
mencoder, I receive the following messages:

The AVI file produced is without video, and the audio is completely  
distorted. I noticed in the messages above, it says that it is  
ignoring the video stream, but mplayer plays the source file  
(including the video stream) without any problems. Is there a way to  
stop it from ignoring the video, and if so, will it also stop the  
audio distortion?

Thank you in advance for any help,
Sean
