Specificationhttps://w3c.github.io/media-capabilities/

Summary

Extends the MediaCapabilities API to support WebRTC streams. The
MediaCapabilities API helps websites to make informed decisions on what
codec, resolution, etc. to use for video playback by providing information
about whether a configuration is supported and also whether the playback is
expected to be smooth. This feature extends the MediaCapabilities API to
also include WebRTC streams.
