main decoder error -> mjpg

[kobe08]

Code: Select all

main decoder error: no suitable decoder module for fourcc `mjpg'. VLC probably does not support this sound or video format.

I can't find out the solution to this problem. I have an application which uses jvlc. To run the application, an vlc installation is needed (0.9.0) and i have installed it (as well as ffmpeg). In the first machine everything went ok. in this second machine i think i done like in the first one but it gives me this error. both machines have Ubuntu 7.10 fresh installations...
after installing ubuntu 7.10 i installed many libraries which ffmpeg demanded, and then compiled and installed ffmpeg and then the same with vlc 0.9.0...

what am i missing? any help?
thanks in advance

Can you paste the output of vlc -vvv --list | grep ffmpeg ?

Here it is:

This means that your ffmpeg plugin is miscompiled.
