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

[Jens-Rainer Ohm]

Dear Shailendra,
The newest version of the Microsoft reference code (with all known bugs
fixed) was recently approved in the context of 14496-5/AMD5, which is
presently in the process of publication by ISO. This will then probably
be published on the ISO Web Site in the near future. This code is
already available from the MPEG Video Group software maintenance site
http://megaera.ee.nctu.edu.tw/mpeg/Ref_Software/cd_software_with_FGS/,
and has now also been copied to the NIST CVS in sub-directory
microsoft-2.5-040207-NTU/.
Best regards,
Jens

> Hi All,
>     Currently I have 2 sets of MPEG-4 reference software :
>     - From ISO's site, 
> (http://www.iso.ch/iso/en/ittf/PubliclyAvailableStandards/1449
> 6-5_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 ?
