HLS.js is a JavaScript library that implements an [HTTP Live Streaming] client. It relies on [HTML5 video][] and [MediaSource Extensions][] for playback.
It works by transmuxing MPEG-2 Transport Stream and AAC/MP3 streams into ISO BMFF (MP4) fragments. Transmuxing is performed asynchronously using a [Web Worker] when available in the browser. HLS.js also supports HLS + fmp4, as announced during WWDC2016.
