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 version is a bug fix release.
Please note that there is still a known bug in the bipredictive motion
estimation which was introduced in JM 14.1 and has not yet been finally
fixed.
Best regards,
Karsten

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

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 release fixes some bugs in the 13.x series especially for 4:4:4 and 4:2:2 chroma modes.
This is also the first release that contains I_PCM macroblock decoding with CABAC for streams with more that 8bpp. So this is actually the first feature complete bumping decoder for FRExt/Professional profiles.
As always the complete list of changes is attached below.
Best regards and happy holidays,
Karsten
