Looks like this was started, but not finished. How far did it get? Are there plans to do anything more with it? Thanks.

Hello, the jp2 container (part 1, annex I) is mostly done but likely not consumable. I'm planning to implement jpxml (part 14) before going onto decoding the code stream. I have created a library for the arithmetic coding which is needed for decoding the code stream, but unable to verify correctness just yet. What use cases are you looking to cover?

John-Nagle commented 3 years ago

All I need is JPEG 2000 decode. I'm working on a Second Life viewer, and all their assets are in JPEG 2000. I'm using the crate that calls the C library, but it sometimes segfaults. Hence the desire for an all-Rust solution.

Unfortunately the completion of this project is unlikely to meet your deadlines. I'm not sure which JPEG2000 implementation you've tried, but there are a few JPEG 2000 implementations; openjpeg, grok, jasper and kakadu (closed source). If you know of any other open source ones let me know.

Did not know about "grok". Knew about the others.
