Media Source Extensions API (MSE)

[ferjm]

Spec: https://www.w3.org/TR/media-source/

[ferjm]

This branch contains some of the DOM bits that were implemented for gecko-media and that we may be able to reuse.

WebKit has a GStreamer based implementation of this API http://eocanha.org/blog/2016/02/18/improving-media-source-extensions-on-gstreamer-based-webkit-ports/

@ferjm I'll take care of this as a short trip in servo codebase.

@csmoe Thanks for your interest in working on this issue!

Note that this is a pretty large project. A big chunk of the work should likely happen in https://github.com/servo/media and it will require quite some knowledge of how GStreamer works.

At the moment there are no specific plans or proposed architectures for this API other than following WebKit's one), so unless you want to propose an alternative approach, I would start by trying to prototype their GStreamer pipeline (here) (ideally along with similar MediaSource, SourceBuffer and MediaPlayer abstractions).

WPT tests for the Fetch API care about this.
