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

[Funta]

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

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?
