| getStats |
| 1. Let selector be the RTCRtpSender object on which the method was invoked. |
| 2. Let p be a new promise, and run the following steps in parallel: |
| 1. Gather the stats indicated by selector according to the stats selection |
| algorithm. |
| 2. Resolve p with the resulting RTCStatsReport object, containing the |
| gathered stats. |
| 3. Return p. |
| |
| 8.5. The stats selection algorithm |
| 3. If selector is an RTCRtpSender, gather stats for and add the following objects |
| to result: |
| - All RTCOutboundRTPStreamStats objects corresponding to selector. |
| - All stats objects referenced directly or indirectly by the RTCOutboundRTPStreamStats |
| objects added. |
