FF142 adds support for the dictionary property
RTCRtpEncodingParameters.codecin https://bugzilla.mozilla.org/show_bug.cgi?id=1894137This is used when setting encodings in
RTCRtpSender.setParameters(parameter.encodings)andRTCPeerConnection.addTransceiver(sendencodings), and returned inRTCRtpSender/getParameters()(encodings.codec).This updates the
setParameters()- encodings - subfeature on the sender. ThegetParameters()andRTCPeerConnection.addTransceiverfeatures don't go down to the same level - my assumption is that you don't want to record this because it would likely always duplicate.The version values for chrome and safari were found by running https://wpt.live/webrtc/RTCRtpParameters-codec.html on browserstack.
