Work did not seem to progress as far - the ambitions may have been higher than what is possible in 12 weeks. I believe your work will have long-lasting impact.JPEG2000 in FFmpegKamil Nowosad from Warsaw University took on the task of embedding a JPEG2000 decoder and encoder for FFmpeg. Until then, I doubt it would hurt, but I also suspect it would fall on deaf ears.Congratulations to Ben for taking the JPEG2000 integration into Firefox this far. ![]() Once the dust from that has settled down, I think Stuart Parmenter would be much more receptive to the idea of adding an image decoder to Gecko. The crux of the problem can be summarized as "why include J2K support in the core browser when it is hardly used?" followed closely by "why use J2K when users would have to install extra software to see the images?"I think, down the road, a list of major users of JP2 would be helpful, but the folks who work on Mozilla full-time are caught up with the transition from the 1.9 version of the the core code (Gecko), to version 2.0, a fairly major task. Once I have the major platforms covered, I'm going to submit the extensions to also talked about the chicken-and-egg problem of getting JPEG2000 support into the core browser code. I have updated trunk (Firefox 3) builds for Windows and OS X posted to, and will make Linux and Firefox 2 builds in the next few days (hold me to it!). He has given me permission to summarize our conversation here.I was able to successfully create XPIs for the three major platforms that enable in-line decoding of JP2 images.
