[Mp4-tech] JM 9.4 decoder trace file

[Sabeva Galina]

Dear all,
I try to find in code of JM 9.4 decoder where are determined the
macroblock and sub macroblock partitioning.  
In the trace file I have lines like this:
@10221 mb_type			22
@10222 sub_mb_type		1
@10223 sub_mb_type		10
@10224 sub_mb_type		5
@10225 sub_mb_type		6
Can someone tell me what is the range of values that mb_type and
sub_mb_type can have and what they mean (how can I connect the
sub_mb_type=2 for example with sub macroblock partition 4x4)?
Thank you in advance
Galina
