| 21 | getParameters |
| 22 | When getParameters is called, the RTCRtpParameters dictionary is constructed |
| 23 | as follows: |
| 24 | |
| Soares Chen | 172fe9d | 2017-07-18 09:30:18 | [diff] [blame] | 25 | - The headerExtensions sequence is populated based on the header extensions that |
| 26 | the receiver is currently prepared to receive. |
| 27 | |
| 28 | - The codecs sequence is populated based on the codecs that the receiver is currently |
| 29 | prepared to receive. |
| 30 | |
| 31 | - rtcp.reducedSize is set to true if the receiver is currently prepared to receive |
| 32 | reduced-size RTCP packets, and false otherwise. rtcp.cname is left undefined. |
