Unfortunately we lost all changes in the bug tracker between Oct. 22nd and Oct. 29th due to a hardware failure.
I'm sorry for the inconvenience. Please check your reports.

Dear experts,
I uploaded a new release of the JM H.264/AVC reference software to my
web site at:
http://iphome.hhi.de/suehring/tml/download/
The is the first version that has feature complete support for the new
professional 4:4:4 profiles. Please test these features extensively.
I have removed the work spaces for MS Visual Studio 6.0 for different
reasons: I do no longer have this old development environment installed
on my PC, so I can't support any problems with that, which includes
adding new files. Microsoft also has stopped the support for VS6 pretty
long time ago. And the current code has encoder/decoder mismatches due
to compiler bugs that were only fixed in the last VS 6 Service Pack.
This release also contains various bug fixes and optimizations. It now
allows loss of single data partitions, which was an often requested feature.
For the full list of changes, please see below.
Best regards,
Karsten

Dear experts,
I uploaded a new version of the JM H.264/AVC reference software to my
web site at:
http://iphome.hhi.de/suehring/tml/
This release contains only an update of the sample configuration file, a
fix for 4:4:4 independent mode in combination with scaling matrices and
and update of the the included reference manual.
The release is aligned with the software that has been submitted for
ISO/IEC 14496-5:2001/PDAM 18 (Professional profiles reference software).
Best regards,
Karsten

Dear experts,
I uploaded a new version of the JM reference software to my web site at:
http://iphome.hhi.de/suehring/tml/
This version is mostly a bugfix and cleanup release. Most important it
contains an impressive decoder speedup (with gcc 4 the decoder is twice
as fast) and fixes a weighted prediction mismatch which was introduced
in JM 12.1.
The work on integrating the new 4:4:4 profiles is still ongoing. This
release contains only some of the necessary modifications.
Please the the changelog below for a complete list of changes.
Best regards,
Karsten
