That's helpful, it should be looking for libavcodec.so.57 instead. 
Probably something in ff or a library used by it (gst?) has been written 
for a distro that packages both ffmpeg and libav and renames ffmpeg 
libraries.

Unless it looks for libavcodec.so.57 as well, the fix may be as simple 
as sed -i -e 's,libavcodec-ffmpeg,libavcodec,g' on the file triggering 
this.
