Last week, the HTML Media Extensions Working Group published a W3C Recommendation of Media Source Extensions™. It is the first specification reaching the status of Recommendation that stems from the series of W3C workshops held by the Web and TV Interest Group since 2010, and was one of the main outcomes of the Second W3C Web and TV workshop in particular.
Media Source Extensions is not only about facilitating adaptive streaming on the Web. Thanks to its design – based on a “low-level splicing and buffering model” – the door is open to other use-cases: time-shifting and video editing, and more innovative solutions such as 360° video players.
Flexible and powerful, Media Source Extensions is implemented by all major browsers and provides commercial quality IP streaming for Web applications, across different platforms and between unrelated companies. It is under the hood of today’s main video platforms and content providers, e.g. Netflix and Youtube, and is supported by main video players like JW Player.
