Comment 2 Sebastian Dröge (slomo) 2015-07-08 08:48:21 UTC 
Doesn't it mean that with channels==0, the channel mapping is provided elsewhere in the ADTS header?
Comment 3 sangkyu.choi 2015-07-08 13:40:38 UTC 
i thinks thant "channels == 0" is also ADTS frame.
in  this case, it does not a detect as a ADTS.

Channel Configurations

These are the channel configurations:

    0: Defined in AOT Specifc Config
    1: 1 channel: front-center
    2: 2 channels: front-left, front-right
    3: 3 channels: front-center, front-left, front-right
    4: 4 channels: front-center, front-left, front-right, back-center
    5: 5 channels: front-center, front-left, front-right, back-left, back-right
    6: 6 channels: front-center, front-left, front-right, back-left, back-right, LFE-channel
    7: 8 channels: front-center, front-left, front-right, side-left, side-right, back-left, back-right, LFE-channel
