[Mp4-tech] How to do conformance test for MPEG4 Advanced Simple profile (Video)

[Arhold]

Hi guys,
I have a problem of doing conformance test for mpeg4 asp. Basicly
someone else have already raised this question before, but I didn't
find the answer.
It seems that the ASP part are not included in the ISO/IEC 14496-4
Part 4: Conformance testing. According to description in
http://www.m4if.org/resources/profiles/index.html, ASP was been added
in the 2nd Extension to the 2nd Edition of the MPEG-4 Visual standard.
So I guess the conformance test may be in the 2nd Extension. Am I
right? Could some one tell me which spec should I refer to for the ASP
conformance test?
Thanks & Regards,
Arhold
