I would love to see Robin's test harness. I would also love to see the
images that failed with v2.
I started diving into the v2 branch of OpenJPEG a few days ago, after
research JPEG 2000 for a week. Tackling the bugs from the failed images
might be a good way to become more familiar with the source code.
I posted a very minor patch correcting some simple build problems with the
DLL version of OpenJPEG V2.

Does anyone have a sense of how actively the OpenJPEG source code is
maintained?
Thank you for publishing your results, Robin. They are encouraging me to
continue looking at OpenJPEG v2.
