[Libav-user] problem with ffmpeg on mac vs win

[Craig Murray]

I've done my best to get ffmpeg building on mac with
--enable-libaacplus --enable-nonfree.... the build seemed to work as
far as I can tell.  But now when I run the same command I'm getting a
different problem.

/ffmpeg -i test.avi -y test.mov
