That's an error in FFMPEG, not in VLC. You might have checked out a buggy version of FFMPEG, or worse, you corrupted your build tree.

ok, thanks for your help...
a friend told me the failure may be here "libavutil/pixdesc.h: No such file or directory"

Of course it is the failure.

Remi's point is: The problem happens whike compiling the contribs.
It seems that either ffmpeg svn was broken when you got it or you copy is broken.

So try again.

The real question though is why are you using the contribs ? It normally reserved for crappy OS without proper package management.

On linux, you should get the necessary libraries from your distribution
