parse ts pcm stream

[niror]

hi all,

I'm trying to parse pcm audio packet from transport stream file, but I'm missing 4 bytes

 47 51 00 11 00 00 01 BD 03 CC 84 80 05 21 0C DF F3 01 03 C0 31 60 00 00 00 00 00 00 FF FF FF FF ...
|___________|___________|_____________________________|___________|______________________________...
 ts packet   PES Sync      PES Header                   ????????    Raw pcm 2ch 48khz 16bit
 header      Private 
             Stream 1

can anybody tell me the format for the pcm header i'm missing?

ran.

I am no expert. But this is what I know.

size in bytes = 16 bits
channel assignment = 4 bits
sampling frequency = 4 bits
bits per sample = 2 bits
start flag = 1 bit
reserved = 5 bits

channel assignment
1 = mono
3 = stereo
4 = 3/0
5 = 2/1
6 = 3/1
7 = 2/2
8 = 3/2
9 = 3/2+lfe
10 = 3/4
11 = 3/4+lfe

sampling frequency
1 = 48 kHz
4 = 96 kHz
5 = 192 kHz

bits per sample
1 = 16
2 = 20
3 = 24

Your example of 03 C0 31 60 is:

960 bytes
stereo
48 kHz
16 bits/sample
start flag is on
