[MPlayer-users] mpeg2ts/aac problem

[Nico]

I checked that file.
The problem is that the descriptor assigned to AAC in TS in the standard 
(0xf) in your case is correctly assigned
only to the audio pid, but in all the samples I have it's assigned to 
all pids (even to video and sub pids),
so I commented the code to tag  it as AAC. What happens is that the 
demuxer sees that pid as MP2,
which obviously isn't.

You can do two things:
1) in parse_descriptors decomment the code regarding case 0xf and in 
parse_pmt change this block:

//if((type_from_pmt == 0x0f) || (l == 4)) //see in parse_pmt()
if(l==4)
       es->type    = AUDIO_AAC;

to
if((type_from_pmt == 0x0f))
     es->type    = AUDIO_AAC;

that should work as expected

2) try to discover what's the meaning of the descriptors used by those
japanese broadcasters. If it weren't for the mess they make in the PMT the
code would be already working correctly.

BTW I'm planning to add an option to permit users to force a decoder.
