[Mp4-tech] how to play .aac fille with adif header

[Apoorva soc-soft.com]

Hello Gomathi,
AAC bit stream according to the standard, contains only syntactic
elements (SCE, CPE, LFE, DSE, PCE, FILL, CCE, TERM). So if an AAC
decoder is developed, it will be implemented to support and decode the
syntactic elements compulsorily. Let us call the AAC containing only
syntactic elements as "Raw AAC".
When we consider ADTS or ADIF, these are headers which provide
information about the bit stream like sampling rate, channels, etc. And
these headers (ADTS, ADIF) are not the only format, AAC bit stream could
be encapsulated in. Raw AAC can even be a part of MP4 transport stream,
in which the data like Sampling rate and channels will be a part of
configuration information. 
So, if a player has AAC decoder but, do not have the implementation to
decode the headers (ADTS, ADIF) then, the player can very well decode
the "Raw AAC" (information of Sampling rate will have to be provided by
the user) but, will not be in a position to decode the AAC with ADTS or
ADIF header.
Hope this helps,
Apoorva Ankad

Hi all....
   Thanks a lot for ur replies.can i know the reason behind why only
certain players  could play the .acc with ADIF header.B'coz both ADIF
and ADTS headers can be used to create .aac file in general.I think the
only difference being one time ADIF header for the whole stream and
ADTS for every frame.If i'm correct why the normal players couldn't
play that.is there any special thing the decoder should do to decode
aac stream with adif.....expecting replies...
Thanks in advance,
regards,
Gomathi.
