At least libogg, libvorbis, libopus, and libtheora can be built to JavaScript using [http://emscripten.org/ emscripten] pretty straightforwardly.

'''[https://github.com/brion/ogv.js ogv.js]''' is a wrapper around these with basic JavaScript interfaces and video/audio playback wrappers semi-compatible with the native HTML5 <video>/<audio> elements.

	Currently ~~the internal interfaces are very much in development. I~~ (~~[[User:Brion]]~~) ~~hope to get these~~ in use for ~~playback of~~ audio ~~and~~ video ~~content~~ on Wikipedia and Wikimedia Commons ~~in browsers that don't support Ogg or WebM natively, as our community has rejected the idea of making and serving out MP4 transcodes for those browsers~~.		Currently (August 2015) in use for audio/video playback in Safari/IE/Edge browsers on Wikipedia and [https://commons.wikimedia.org/wiki/Commons:Media_of_the_day Wikimedia Commons].

Live encoding from getUserMedia may be possible but I suspect frame rate will be awful as there's no way to grab the bits directly... and of course encoding is likely to be slow.
