WebRTC Scalable Video Coding extensions

This extension defines a standard method for picking between possible Scalable Video Coding (SVC) configurations on an outgoing WebRTC video track.

Many video codecs (VP8, VP9, AV1, H264-SVC) have modes that allow an encoder to send out video data in such a format that it's possible to strip out certain packets from the stream and reconstruct a lower quality video stream from the result. This makes providing video at differing qualities to multiple destinations for the same video stream easier.
