Service Worker Caching, PlaybackRate and Blob URLs for Audio and Video on Chrome for Android
From version 52, Android Chrome uses the same media stack as desktop Chrome, rather than relying on the underlying platform implementation. This enables service worker media caching, variable playback rates, blob URLs on Android, MediaStream passing between APIs, and easier cross-platform debugging.
Media Source API: Automatically Ensure Seamless Playback of Media Segments in Append Order
The MediaStream API represents synchronized streams of audio or video. MediaStream.ended, MediaStream.label and MediaStream.stop() are being deprecated. Use MediaStream.active, MediaStreamTrack.label and MediaStreamTrack.stop() instead.
Media playback notifications for Chrome on Android
When audio or video is playing on a web page, a notification showing the page title and a play/pause button is displayed in the notification tray and on the lock screen. The notification can be used to pause/resume play or return to the page playing the media.
Media Source Extensions (MSE) provide extended buffering and playback control for the HTML5 audio and video elements. While originally developed to facilitate Dynamic Adaptive Streaming over HTTP (DASH) based video players, MSE can be used for audio; specifically for gapless playback.
