The channel order for AAC decoding isn't an accident at least, as it's
explicitly defined in libavcodec/aac.c.  So it's safe to say that (with
these changes) MPlayer is conforming to ffmpeg's documented order for
AAC decoding, as opposed to a fluke or bug in ffmpeg.

(Note that Vorbis is in the same situation too.)

Now, it might well be true that ffaac and vorbis should be updated to be
more internally consistent.  But ffmpeg is a code base I am much less
familiar with, and the barrier to entry is higher if I'm the one doing
that leg work, to the extent that (knowing myself) it might not get
done.

So, hopefully you guys don't make that a prerequisite to merging these
fixes.

Cheers,
Jason.
