[Mp4-tech] re : Mp4 header format

[Peeyush KULSHRESTHA]

Hi Vishvanath,
ADTS and ADIF are MPEG AAC file formats. The basic difference is the 
number of times header occurs. In ADTS header is present after each data 
block in the bitstream, while in ADIF, header is present only at the 
begining of the file (or bitstream). Therefore ADIF processing cannot 
begin from middle since no header will be there. Because of this ADTS is 
used for broadcasting type purposes and ADIF for storing on disk type 
purposes.
Abt MP4 I don't have much idea, but it is a file format used for 
presenting mpeg-4 coded multimedia data, like editing, streaming etc.
Hope it helps.
regards,
Peeyush.
