I made a in-browser MKV player / parser / fMP4 remuxer (help wanted)

[gyf304]

I made a in-browser MKV parser / player at https://github.com/gyf304/jsmkv. It allows playback of MKV files in browser by remuxing them on-the-fly to fMP4 streams.

Demo available at: https://gyf304.github.io/jsmkv/demo-http.html

Right now the demo works with Firefox, Edge, and Chrome. However it does not work with Safari as it does not like the fMP4 it generates. If someone can recommend me a good MP4 validator, I would be very grateful.

A sample fMP4 file generated can be found at https://drive.google.com/file/d/1LKhAKgsnYNEa7TpA5Ux26yCv4Pz8QPc6/view?usp=sharing if you are willing to take a look.

Nice idea, but with mp4 we will lose a lot Matroska features, and I have looked at your code and there is no support for ordered chapters, which is the most important Matroska feature.
