FPWD: MediaStreamTrack Content Hints

MediaStreamTrack Content Hints

https://www.w3.org/TR/2018/WD-mst-content-hint-20180703/

Abstract


This specification extends MediaStreamTrack to provide a media-content hint attribute. This optional hint permits MediaStreamTrack consumers such as PeerConnection (defined in [webrtc]) or MediaRecorder (defined in [mediastream-recording]) to encode or process track media with methods more appropriate to the type of content that is being consumed.

Adding a media-content hint provides a way for a web application to help track consumers make more informed decision of what encoder parameters and processing algorithms to use on the consumed content.
