[M4IF Technotes] Is standard conform to put mp3 sound in aMPEG-4 stream ?

[AVARO Olivier FTRD/DIH/REN]

Seems that this solves the issue :
- streamtype shall be 0x05 (this is an AudiioStream)
- objecttype shall be 0x6B (this is Audio ISO/IEC 11172-3 MPEG-1 Audio)
- decoderspecficinfo : empty
- access units in this case are the frame() bitstream element as is
defined in ISO/IEC 11172-3.
Just if someone knowledgeable on ISO/IEC 11172-3 can confirm that the
signaling of possible P&L are done in-band ... Anybody ?
Kind regards,
Olivier
