I have a naive question as I'm toying w/ a similar WebRTC project myself. Since all browsers support h264/opus, can I just reasonably ask each client to send 720p to my WebRTC peer which is really a server before I relay it? Then, can't we just use naive e2e encryption with any extra encoding/decoding? Meaning, in my TransformStream, can I just window.subtle.encrypt on the way out and window.subtle.decrypt on the way in? Is it due to the fact that the insertable streams have to remain in their video format? Pardon my ignorance. This naive approach does assume everyone can at least handle the download speeds of the group's video and the upload speed of their own.
