HLS Player is a Chrome extension that serves as an HTTP Live Streaming (HLS) client. It allows users to play .m3u8 HLS streams directly in their browser. This extension relies on HTML5 video and MediaSource Extensions for seamless playback.

The functionality of HLS Player is based on transmuxing MPEG-2 Transport Stream and AAC/MP3 streams into ISO BMFF (MP4) fragments. This process can be performed asynchronously using a Web Worker if supported by the browser. Additionally, HLS Player also supports HLS + fmp4, as announced during WWDC2016.

With HLS Player, users can easily access and enjoy HLS streams without the need for additional software or plugins. It provides a convenient solution for streaming content in the m3u8 format, making it a valuable tool for those involved in media streaming and playback.
