> Ok, this is AVC long gop.
> The essence stream copy works fine - binary match.
> But the index metadata is lost: your input is actually correct as you said, the index table is VBR with video tagged posTableIndex=-1 to apply temporal reordering.
> The output is not, video has posTableIndex=0 (and temporalOffsets = 0), so no reordering, so bad.
> A trac ticket already exists:

Dear Nicolas,
I appreciate your help.
I am going to provide some more info on the trac you introduced.
Thank you again.
