New release of H.264/AVC reference software JM 17.1

-- this blog post is based on the email sent by Karsten Sühring to the JVT reflector

A new release of the JM reference software is available at http://iphome.hhi.de/suehring/tml/

This is a quite large maintenance release: It contains a number of bug fixes including a decoder issue that was introduced in JM 17.0 and caused a mismatch for MBAff and constrained intra prediction.

The documentation has been updated with a description of the new MVC coding mode. Many people experienced crashes when enabling MVC with the default config file. This was caused by an incompatible setting which is now prohibited for the muti-view encoding mode. We have also added a Stereo High profile example config (encoder_stereo.cfg) and a modified default file for faster encoding (encoder_fast.cfg).

The VS 2008 and XCode workspaces have been updated for better x64 architecture support. OPENMP (for parallel deblocking) is now enabled by default (also in the Makefiles).
