[Libav-user] AAC 4.0 on Android error

Hi I have a question about encoding audio into AAC 4.0 on Android. I set my
channel count to 4 and my channel layout to AV_CH_LAYOUT_4POINT0 but when I
try to configure my filter graph (with that as an output) I get

FFMPEG Error Level:16 Log: Output channel layout '5 channels
(FL+FR+BR+FLC+SL)' is not supported

Which doesn't make sense, mainly because I set it to 4 channel. Am I using
this incorrectly?

Thanks,
Michael
