| interface RTCRtpReceiver { |

| getStats |
| 1. Let selector be the RTCRtpReceiver 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 |
| 4. If selector is an RTCRtpReceiver, gather stats for and add the following objects |
| to result: |
| - All RTCInboundRTPStreamStats objects corresponding to selector. |
| - All stats objects referenced directly or indirectly by the RTCInboundRTPStreamStats |
| added. |
