Hi
I'm trying to parse an AAC-LD (LATM) stream.
My goal is to figure the total length of the frame - header and payload,
and find the first byte of the payload.
Unfortunately my reference code is missing the LATM parsing functions, 
So after reading the AudioMuxElement info, I'm not sure what to do with
it.
- Packet total length: 160 bytes.
- MuxSlotLengthBytes is called twice. Get 72 and 13.
1.	Is my payload length 72 + 13? 
2.	Does the payload starts where the AudioMuxElement finished (bit
69)?
3.	What happens with the other 66 bytes? Is there a new
AudioMuxElement in the same packet?
I would appreciate it if anyone could refer me to a good LATM reference
code
Thanks In advance 
Yifat
