For AAC conversion from 5.1 channels to 2 channels, ffmpeg code uses
surround_to_stereo() in libavcodec/Resample.c
In that the input data was packed in the format fl, fr, c, lfe, rl, rr
fl = input; // front left
fr = input; // front right
c = input; // center
lfe = input; // low frequency effects
rl = input; // rear left
rr = input; // rear right
I would like to convert AAC 7.1 channels to 2 channels.
But i have no idea about how the input data is packed.
Can anyone please tell me how the input data format is arranged for AAC 7.1
