Description

GStreamer 1.22 saw the introduction of a new plugin for adaptive playback of HLS, DASH and MSS streams. The new elements take a substantially different approach to playing those types of streams, with better buffering and bitrate selection as well as features like LL-HLS playback. This talk will explain how these elements improve upon the older adaptive demuxers and how they work.
