[FFmpeg-devel] Making progress re: jpeg2000dec patchsets

[Caleb Etemesi]

I haven't seen an open source implementation that implements place holder
passes, the best one is currently openhtj2k(
https://github.com/osamu620/OpenHTJ2K) which only acknowledges their
existence but doesn't do anything with them

I would suggest we move forward if that's the only thing blocking this.
