[Mp4-tech] mpeg aac RAW format

[Apoorva Ankad]

Hi,
      I feel Bit rate is not required, but Sampling frequency, Number of
channels and Audio Object type is required to decode a header less raw
AAC stream.
Regards,
Apoorva.

Hi,
You need to know Sampling frequency, Bit rate and number of audio
channels for AAC raw streams. Based on this information, either you can
initialize AAC decoder & decode the song or create and put ADIF header
at the start of AAC raw.

Hi,
Can anybody plz help.
The scenario:
I am having a AAC coded bitstream which does not have ADTS, ADIF or MP4
header, but may contain AAC coded data in RAW format(which is unknown to
the decoder).  
Whether this scenario is possible? if yes,
How do I determine and handle this bitstream?
rgds,
Datta
