     13The project was to add support for HTJ2K decoding to the native FFmpeg JPEG 2000 decoder (avcodec/jpeg2000). This involves adding a new entropy coder to the existing JPEG 2000 framework. The new entropy coder (specified in ISO/IEC 15444-15 | Rec. ITU-T T.814) significantly speeds up JPEG 2000 encoding and decoding. It is relatively challenging to implement.

     17The project was successful and resulted in a patchset which is under review: https://patchwork.ffmpeg.org/project/ffmpeg/list/?series=8078

     19When patched, FFmpeg can decode JPEG 2000 codestreams that were encoded using the HTJ2K entropy coder.
