MKV support
Right now, WebTorrent uses the videostream package to provide support for MP4. It would be great to be able to stream MKV files since it's a very popular container format.
WebChimera does not work in the browser. But it's an option for Electron or nw.js apps. On Sat, Aug 13, 2016 at 1:45 PM Sander Laarhoven [email protected] wrote:

There is node-matroska, "Matroska library written for nodejs". While node-matroska isn't easily browserifyable the original project, node-ebml, is. I used it to make this tool. My code is quite messy, consider it a proof-of-concept. If node-matroska gets improved and finished maybe it can be used here.
@zekiblue I don't think so: maybe most videos distributed illegally are served using this container (unless you also consider WebM, which is based on Matroska, but isn't MKV), Anyway I'm just guessing: streaming services, AFAIK, are huge, do not use MKV and count for "most of the videos served".
Matroska is just an container, the main issue on supporting MKV is that many videos I find using this container use codecs not supported by many browsers. You can test it by running ffmpeg -i your-video.mkv -codec copy test.mp4 then trying to play the video in a browser. I just tried some random video and it failed.
That being said, if the codec issue gets ignored, one way to solve this issue is reproducing the above command using JavaScript: use node-ebml to parse the MKV file (it works using streams, which is ideal), extract streams from it and remux those into MP4. Subtitle streams can also be extracted and forwarded to some renderer such as JavascriptSubtitlesOctopus or Captionator.js.
