I just compiled a svn snapshot of VLC.

Unfortunately, it doesn't seem to support mjpg streams - when I try to open a mjpg stream from a network camera, VLC says:

No suitable decoder module for format:
VLC probably does not support the "mjpg" audio or video format.
Unfortunately there is no way for you to fix this.

Is it this svn snapshot's fault, or perhaps I gave wrong compilation flags?
As far as I understand, mjpg is supported by ffmpeg - and ffmpeg and libraries are installed here.
With VLC 0.8.6c, mjpg streams are played just fine.
Any clues what might be wrong?

Hmm - the plugin is there, but libffmpeg_plugin.so cannot be loaded, because of undefined symbol. Any ideas why?

How did you compile ffempg?

How did you compile ffempg?

I didn't compile ffmpeg myself - I used what came with my system.
You think the problem may be there?

I don't think, I am almost sure
Build your own ffmpeg ...

Indeed, that was it - thanks for help.

You are welcome

sorry but how could I "build my own ffmpeg?
I saved a screen shot streaming using Capture Fox, a good firefox addon, then I can play the avi file with all player but VLC

thanks
