ffmpeg: symbol lookup error: ffmpeg: undefined symbol: avformat_alloc_context

I wanted to post this so others can use it for future reference.

This is the error from running ffmpeg:
ffmpeg: symbol lookup error: ffmpeg: undefined symbol: avformat_alloc_context

On OpenSUSE 11.0 I had this error and it was caused by a conflicting library that YaST somehow allowed without warning.

I had to uninstall the libffmpeg0 package.
After that my ffmpeg (ffmpeg-0.5.0.19251-1.1) works fine.

I have same problem but when I go to uninstall a warning message comes up with recommendations to change xine libraries - did you just innore the dependency. Looks like libmpeg0 is a dummy file??

Not on my system.

Here's one thing I did recently due to other issues with the same libraries and packages.

Remove the VideoLAN repositories and update all you ffmpeg related packages and see if that helps.
