This seems more like an issue in ffmpeg. I could be wrong, but I don't have an 
idea how I could fix this. Try the git ffmpeg in a few days, or from a few days 
back.

Are you sure you don't have 2 version of ffmpeg installed, one in /usr/lib and 
one in /usr/local/lib ?

Ha, nice catch. local is the git build while the other one is the distributor 
version. I never considered that it would be a problem - but I still don't 
quite get it. I'm pretty sure I built ffmpegthumbnailer at least once with both 
installed. Could you tell me what told you?

Ah, I'm blind. Well, how do I fix this? I compiled 
MPlayer/VLC/gstreamer0.10-ffmpeg successfully several times with this setup.

A linker issue means it can't find functions in the library which it could find 
in the headers. There can be 2 causes, a bug in ffmpeg which is unlikely or a 
mismatch between the headers and the library. This is not the first time people 
complain about linking errors when they use the git or svn versions :-)

It could have worked before if the library from your system is similar to the 
one from git, but as soon as a functions are added to the git headers, the 
linker cannot find these functions in your system library resulting in linker 
errors.

I hope this is a clear explanation ;-)

The safest fix is make sure you only have one version of the ffmpeg libraries 
and headers installed.

Got it working easily now, just created about a bazillion dummy packages in 
Debian so I could keep the git version while satisfying dependencies.

Thanks, and I'm very sorry for stealing your time. I still wonder, does 
ffmpegthumbnailer do something different? Considering all the other 
ffmpeg-dependent stuff seemed to compile just fine, maybe that was just luck 
though :p
