Validates the RTCRtpParameters returned from RTCRtpReceiver.prototype.getParameters
5.3. RTCRtpReceiver Interface
getParameters
When getParameters is called, the RTCRtpParameters dictionary is constructed
as follows:
- The headerExtensions sequence is populated based on the header extensions that
the receiver is currently prepared to receive.
- The codecs sequence is populated based on the codecs that the receiver is currently
prepared to receive.
- rtcp.reducedSize is set to true if the receiver is currently prepared to receive
reduced-size RTCP packets, and false otherwise. rtcp.cname is left undefined.
- transactionId and degradationPreference are left undefined.
