Indeed it wasn't right...
So far we have:
Carl prefers if users patch ffmpeg themselves.
Ronald says commercial libx264 should be treated identically to faac.
Alex agrees with Ronald.
Reimar sees no legal issue, and thinks it's a reasonable change
(although ugly in its current state).
Baptiste also thinks it's reasonable.
It took me a while to understand why Ronald was against it, but I
think I get it now, and my patch was missing some cases. If x264 is
commercially licensed, then it should not be linked with GPL ffmpeg,
and in that case it should be treated identically as faac. But it
should be ok with LGPL ffmpeg.
New patch attached takes both cases into account.
