I am trying to encode 7.1 audio in an aac codec in my program, but the
codec only supports up to 6 channels and I get an error to that effect
if I try to force it to use AV_CH_LAYOUT_7POINT1.
Please provide sample code, 7.1 is supposed to work fine with the
native aac encoder.

Never mind me. I was saving with the ac3 encoder. Sorry for the noise.
Well, I was able to save aac 7.1 audio. However, upon playback I get an
information message that says:
Assuming an incorrectly encoded 7.1 channel layout instead of a
spec-compliant 7.1(wide) layout, use -strict 1 to decode according to
the specification instead.
I use:
avctx->std_strict_compliance = FF_COMPLIANCE_STRICT;
and it removes one of the info messages, but not all. Anyway, it would
be better if the messages were not produced at all. I tried saving with
a channel layout of AV_CH_LAYOUT_7POINT1_SIDE but it resulted in noise
upon reproduction.
