[FFmpeg-devel] Making progress re: jpeg2000dec patchsets

Hi Caleb, Tomas et al.,

I have been experimenting with combining the HTJ2K patchset [1] and
the J2K test patchset [2]:

(a) neither valgrind nor the fuzzer seem to complain
(b) there are code style/cosmetic issues
(c) the HTJ2K block decoder does not yet support placeholder passes
[3], which are not necessarily present

I do not think that (c) is a blocker and recommend that we plan on
merging the combined patchset once the code style/cosmetic issues are
fixed. The idea is to have a baseline from which performance and
feature set can be improved.

Any major concerns with this plan?

I am happy to take a stab at cleaning up the code, unless someone
wishes to do it.
