Play HLS urls in-browser
Extension with an hls.js library from: https://www.jsdelivr.com/package/npm/hls.js
Play the m3u8 links you click on and any m3u8 links you paste into the address bar.
It works by transmuxing MPEG-2 Transport Stream and AAC/MP3 streams into ISO BMFF (MP4) fragments. This transmuxing could be performed asynchronously using Web Worker if available in the browser. hls.js also supports HLS + fmp4, as announced during WWDC2016
hls.js does not need any player, it works directly on top of a standard HTML<video>element.
