Frame structure
Each frame consists of chunks with the following structure:
0-2 always 0xA0 0x00 0x01 3 chunk identifier 4-7 chunk size (big-endian) 8-... chunk payload
Analyzed frames have chunks in the following order:
0x06
(usually takes more than a half of coded frame)0x15
- small, variable size0x09
- 3 bytes long0x02
- two chunks of variable size0x0B
- there are always 16 of them with size=4. Maybe for some Huffman tables?0x0A
- variable size
