[Mp4-tech] MPEG4 HE-AAC test Procedure

[Barak Zalstein]

Hello,
After seeing
http://lists.mpegif.org/pipermail/mp4-tech/2006-November/006992.html , I
have found that latest ISO reference software can be found in
http://ftp2.ansi.org/download/free_download.asp?document=ISO%2FIEC+14496
%2D5%2FAmd6%2FCor1%3A2006
However, comparing the sbr conformance directory to the one found on Fhg
ftp yields that Fhg version is a bit more recent.
The problem is that looking in the test streams directory from
http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_IEC%2014496
-4_2004_Amd_8_2005_Bitstreams/SBR_CONFORMANCE_1.zip , there are some
tests such as al_sbr_cm* , al_sbr_sig_*, and al_sbr_sr_* which are
mentioned in README_SBR_CONFORMANCE.TXT as part of batch testing but are
not handled by conCriteria table in ct_sbrdecoderConfTool.c of the sbr
conformance utility in neither of these versions.
Can anyone shed some light on the subject?
Regards,
Barak
P.S. In addition to earlier question about missing parametric stereo
al_sbr_ps* support in the same sbr conf utility, I have found
http://ftp2.ansi.org/download/free_download.asp?document=ISO%2FIEC+14496
%2D4%2FAmd11%2FCor2%3A2007 document with updated Diff/RMS values, but It
seems that conCriteria table needs to contain different values for each
test, so this aspect is also not clear.
