Hi,
I have some japanese DVB sample that shows that although these broadcasters use
the PMT they surely don't have a clue about the use of descriptors:
every ES_stream (not only audio) has descriptor 0xf, that in the standard is reserved to AAC in ADTS syntax.
Obviously this breaks my PMT parser.

Does anyone have any link to the specification of the descriptors
that these broadcasters use in ther PMTs?

Thanks.

Descriptor 0xf is the private_data_indicator_descriptor. Stream type 0xf is
for AAC audio with ADTS transport syntax.

The private_data_indicator_descriptor is still a tag and a length, so your parser
should just skip over it (just like any other reserved or user private descriptor).

ok, fixed.
Yet I have some sample at home that have stream_type=0xf but
faad crashes when I feed it with them.

Thank you :)
