| 22 | When getParameters is called, the RTCRtpParameters dictionary is constructed |
| 23 | as follows: |
| 24 | |
| 25 | - encodings is populated based on SSRCs and RIDs present in the current remote |
| 26 | description, including SSRCs used for RTX and FEC, if signaled. Every member |
| 27 | of the RTCRtpEncodingParameters dictionaries other than the SSRC and RID fields |
| 28 | is left undefined. |
| 29 | |
| 30 | - The headerExtensions sequence is populated based on the header extensions that |
| 31 | the receiver is currently prepared to receive. |
| 32 | |
| 33 | - The codecs sequence is populated based on the codecs that the receiver is currently |
| 34 | prepared to receive. |
| 35 | |
| 36 | - rtcp.reducedSize is set to true if the receiver is currently prepared to receive |
| 37 | reduced-size RTCP packets, and false otherwise. rtcp.cname is left undefined. |
| 38 | |
| 39 | - transactionId and degradationPreference are left undefined. |
