[Mp4-tech] MPEG-4 Natural video reference code from Microsoft

[Shailendra Singh]

Hi All,
    Currently I have 2 sets of MPEG-4 reference software :
    - From ISO's site, 
(http://www.iso.ch/iso/en/ittf/PubliclyAvailableStandards/14496-5_Compressed_directories/Visual/Natural.zip) 
which contains the microsoft-vfdis-v10-990812 folder
    - On a CD which contains 14496-5 (Reference Software), purchased 
from ISO/IEC. The folder containing the natural video reference code 
from Microsoft is microsoft-2.3-001213.
    The code on the CD appears to be more recent (going by the "990812" 
and "001213" fields in the names of the folders) and also I have seen 
the code from ISO's site fail for a particular bitstream which was 
successfully decoded by the code which came on the 14496-5 CD.
Could someone please clarify :
(1) Is "microsoft-2.3-001213" the latest reference code from Microsoft ? 
If not, how do get access to the latest reference code from Microsoft ?
(2) Another source of reference code seems to be the NIST MPEG CVS 
Repository (accessible from http://mpeg.nist.gov/). One of the earlier 
mails on this mailing indicates that at least for audio, the repository 
is NOT used actively by the reference software developers and does not 
contain the latest audio reference code. Is that the case for video 
(natural, specifically) as well ?
Thanks and Regards,
Shailendra
