Actually RTCRtpCodecCapability does not seem to cut it either, the only requires fields are mimeType and clockRate. That does not cover all the special configurations. There's sdpFmtpLine that is 'The "format specific parameters" field from the "a=fmtp" line in the SDP corresponding to the codec, if one exists.' but "if one exists" implies this is only after negotiation. Also part of the "a=fmtp" line is the codec payload type, and per [comment](https://github.com/w3c/webrtc-pc/issues/2008#issuecomment-431421369), codec payload types vary between m= sections. Not sure how this is supposed to work.
