Specificationhttps://github.com/w3c/webrtc-encoded-transform/pull/163

Summary

Add features to the WebRTC Encoded Transform API that allow: - Creating
frames - Cloning frames - Manipulating frame metadata Background: A number
of use cases have been identified that require the manipulation of WebRTC
encoded media without decoding them first. These include: - Sending data
that has been encoded previously - Sending data that has been received in
encoded form - Receiving data in encoded form and storing it These will be
supported by the new functions. Issue link:
