[FFmpeg-devel] aac encoder patch: allow it to work with 5.1

After some discussion for this trac ticket:
It appears that the internal aac encoder "as is" is broken with 5.1 audio input.
With small test files like those uploaded to the ticket, it seems to
"lose" 3 of the 6 channels, and garble 2 others.
With larger test files, like sintel.mpg linked to the same, it seems
to "lose" 3 of the 6 channels.
As suggested there, adding -aac_coder 0
seems to fix it and allow it to keep all the channels.
So, without knowing really what is going on, attached is a patch for
review to set that as the default, since it appears to work better
than the current behavior, at least.
