Kind of. The openmj2 library that openjpeg2 comes with hasn't been touched
in ~3 years[1] (the only recent commits to that part of the library have
been cosmetic/build related, so it's substantially out of date compared to
openjp2).

This patch updates ffmpeg to use openjp2, not openmj2 (as it currently
does). openjp2 has a ton of fixes and improvements.

I have no idea why the openmj2 library exists, or why its just sitting
there stagnating in the OpenJPEG repo. It'll be nice to get ffmpeg off of
it.
