[Mp4-tech] [Video-Mpeg4 part2] query regarding video_object_layer_verid

[pankaj bajpai]

Dear All,
i am facing problem in interperating meaning of video_object_layer_verid.
As per standard, the defination for this is :
 - video_object_layer_verid = 0x01 ==> object type in table 9-1
 - video_object_layer_verid = 0x10 ==> 
          - object type in table v2-39(in 2001 release of standard)
          - object type in table 9-2(in 2004 release of standard)
Now for simple profile and simple object, neither table v2-39 nor 
table 9-1, contains simple object.
Hence for simple profile and simple object combination, the value
should be 0x01.
But in of the sequence i found that it is 0x02 for the same combination.
Though that sequence donot use any tool outside simple profile but still
this value is 0x02.
To be more clear on problem, as per my understanding of this as 0x01,
i am not reading flags/header related to 0x02 (like quarter_sample).
Though value of these headers conform to simple profile (eg quarter_sample =0)
in this sequence, but since i ma not expecting this, so my decoder failed to
decode the same.
Please help me in this regard
Pankaj
