Re: [webrtc-encoded-transform] Is frame-level fanout in scope of WebRTC encoded transform? (#211)

If using a webcodecs encoder to encode a frame that is to be sent on an RTCPeerConnection, there has to be a step that supplies the metadata that the WebCodecs encoder does not supply. Doing that as part of the conversion step between WebCodecs encodedFrame and RTCRtpEncodedFrame seems logical. It's a small amount of data.

WRT the PT, I think we're getting to a consensus that frames should be marked with MIMEtype, and that the processing step that needs a PT should look up the PT from the MIMEtype - since this lookup is transceiver-dependent, it seems logical to do the lookup when the frame is enqueued on a packetizer, not before this.

This means, of course, that MIMEtype needs to be writable.
