Automatic update from web-platform-testsRTCRtpReceiver.getStats() in blink added behind flag. This exposes RTCRtpReceiver.getStats() in JavaScript (behind flag) which implements the stats selection algorithm[1] for receivers. (This is similar to RTCRtpSender.getStats(): https://chromium-review.googlesource.com/c/chromium/src/+/975306) [1] https://w3c.github.io/webrtc-pc/#dfn-stats-selection-algorithm Bug: 680172 Change-Id: I8049a52fcaa3c2bd51e5541c7149d9b3aee57e3d Reviewed-on: https://chromium-review.googlesource.com/976121 Commit-Queue: Henrik Boström <hbos@chromium.org> Reviewed-by: Taylor Brandstetter <deadbeef@chromium.org> Cr-Commit-Position: refs/heads/master@{#546801} wpt-commits: f30b60b6c146a653f31ae5c92297a9639d16d450 wpt-pr: 10219 wpt-commits: f30b60b6c146a653f31ae5c92297a9639d16d450 wpt-pr: 10219

5.3. RTCRtpReceiver Interface
|
|
interface RTCRtpReceiver {
|
|
Promise<RTCStatsReport> getStats();
|
|
...
|
|
};
|
|
|
|
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.
