  // Test is based on the following editor draft:
  // https://w3c.github.io/webrtc-pc/archives/20170605/webrtc.html

  // The following helper functions are called from RTCRtpParameters-helper.js:
  //   validateReceiverRtpParameters

  /*
    Validates the RTCRtpParameters returned from RTCRtpReceiver.prototype.getParameters

    5.3.  RTCRtpReceiver Interface
      getParameters
        When getParameters is called, the RTCRtpParameters dictionary is constructed
        as follows:

        - encodings is populated based on SSRCs and RIDs present in the current remote
          description, including SSRCs used for RTX and FEC, if signaled. Every member
          of the RTCRtpEncodingParameters dictionaries other than the SSRC and RID fields
          is left undefined.

        - 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.
