Dear experts,

I have uploaded a new release of the JM reference software to my web site at:

http://iphome.hhi.de/suehring/tml/

This new release provides updates which include support of new distortion metrics beyond PSNR, bi-predictive motion estimation for partitions smaller than 16x16, improved motion compensation precision using weighted prediction methods, proper SP decoding support, and generic bug fixes and cleanups among others. As always, see below for the detailed list of changes.

This release has also been submitted to MPEG as FDAM for the professional profiles and replaces all previous JM versions in ISO/IEC14496-5:2001 (MPEG-4 Reference software).

The reference software manual has not been updated yet.

Best regards,
Karsten
