[Libav-user] Is there a way to encoding PCM to AAC?

Problem solved
I had to guess channel layout if there is no channel layout value

if(in_acodec->channels > 0 && in_acodec->channel_layout == 0)
	in_acodec->channel_layout =
else if(in_acodec->channels == 0 && in_acodec->channel_layout > 0)
	in_acodec->channels =

The output has well transcoded
But, I'm wondering pcm channels how to be plenty
My expectating channels are mono(1) or stereo(2)
Is there PCM 3 channels or more(e.g. 5, 7.1) possible exist?
