Subject: [PATCH] From Alberto Luacus, "The ffmpeg plugin fails to compile with
 the upcoming libav 0.8 because the required header mathematics.h is not being
 included explicitly.

I have just included it, and verified that this also works with current
version 0.7, since the header is also available there."
