There are new methods related to the sources and contributing sources on RTCRtpReceiver and we should implement them and their associated objects. Implementing new methods on RTCRtpReceiver: * getContributingSources [1] * getSynchronizationSources [2] These new methods are expected to be called at a high frequency and special care should be taken to insure that they are performant.

Comment on attachment 8913868 [details] Bug 1363667 - P4 - adding rtp audio level observer; https://reviewboard.mozilla.org/r/185268/#review191056 > When these numbers are different, how are the CSRCs and audio levels matched up with each other? The lists are in the same order. It is expected that the number of reported audio levels can be less than the number of CSRCs, but the inverse should never be true. Adding a sanity check. > Is there a possibility for the array of CSRCs to change size between calls? If so, can there be fewer, or changed CSRCs such that the "old" CSRCs would remain in the mCsrcAudioLevels? Yes, we need to keep a history of the last values associated with eash CSRC within a 10 second window. That window was enforced in JS, but I am going to do that here as well. > When/who calls this? Fixed. > Should outContributingSources be cleared even if no observer is found? In the case of not finding an observer is NS_OK the right thing to return? If no observer is found, it is because the track is a video track, in that case the proper thing to do is return an empty list.

This method scans the history for the entry whose timestamp is closest too a given timestamp but no greater. Because it is scanning forward, it keeps track of the closest entry it has found so far in case it overshoots. There is no before map.begin() which complicates things, and I have to track if something was really found. If that didn't answer the question, let me know.

This bit from above is exactly what I would have wished to see as the comment: Because it is scanning forward, it keeps track of the closest entry it has found so far in case it overshoots. There is no before map.begin() which complicates things, and I have to track if something was really found. Makes perfect sense!
WebIDL review information: These patches add the methods getContributingSources[0] and getSynchronizationSources[1] to RTCRtpReceiver[2] and associated RTCRtpContributingSource[3] and RTCRtpSynchronizationSources[4] dictionaries. Note: that a change was approved at the latest TPAC though a PR has not yet been submitted. This change proposes to make RTCRtpContributingSource and RTCRtpSynchronizationSources dictionaries instead of interfaces. We do not anticipate any changes to the fields. Note: we do not currently support the voiceActivityFlag. Note: there is an error in the spec WebIDL for RTCRtpSynchronizationSources where the audioLevel is not annotated as mutable.

Hi, the Thunderbird sheriff here. Is it possible that this busted our Windows builds? https://treeherder.mozilla.org/#/jobs?repo=comm-central&revision=ede07b1d8a69a49eb1dca01c22c042951b666142 c:\builds\moz2_slave\tb-c-cen-w32-00000000000000000\build\mozilla\media\webrtc\signaling\src\media-conduit\AudioConduit.h(256): error C2220: warning treated as error - no 'object' file generated I saw the failure on try-comm-central before so I did a clobber before triggering a build on comm-central, but it didn't help.

Jorg, yes, it looks like it. I am looking into this now.

Looks like a const mismatch on this line: void GetRtpSources(const int64_t aTimeNow,
Jib, yes. I am about to push to try.

Documentation work should be done, although I would appreciate a review (for which I'm ni'ing Nico). In the absence of review comments or changes, I will assume the documentation listed below is done for the purposes of this bug. Please let me know if you see any issues (or feel free to tweak things yourself!). The changes made follow: Pages created: https://developer.mozilla.org/en-US/docs/Web/API/RTCRtpReceiver/getSynchronizationSources https://developer.mozilla.org/en-US/docs/Web/API/RTCRtpSynchronizationSource https://developer.mozilla.org/en-US/docs/Web/API/RTCRtpSynchronizationSource/voiceActivityFlag https://developer.mozilla.org/en-US/docs/Web/API/RTCRtpTransceiver (a very early draft) https://developer.mozilla.org/en-US/docs/Web/API/WebRTC_API/Intro_to_RTP (early draft) (the draft pages are incomplete but a review of the current content would be helpful since it's relevant) Pages updated: https://developer.mozilla.org/en-US/docs/Web/API/RTCRtpReceiver/getContributingSources https://developer.mozilla.org/en-US/docs/Web/API/RTCRtpContributingSource https://developer.mozilla.org/en-US/docs/Web/API/RTCRtpContributingSource/source https://developer.mozilla.org/en-US/docs/Web/API/RTCRtpContributingSource/timestamp https://developer.mozilla.org/en-US/docs/Web/API/RTCRtpContributingSource/audioLevel (Updates to existing pages generally include both info about Firefox compatibility and improvements to overall quality, content, and so on) Pull Requests submitted: https://github.com/mdn/kumascript/pull/575 (adds missing interfaces to the database for WebRTC) And, finally, added a note to Firefox 59 for developers: https://developer.mozilla.org/en-US/Firefox/Releases/59#Media_and_WebRTC

I'm reopening this from the doc's perspective. Sheppy, these are new pages, you should make a PR to add the compat data to the BCD repository. Thank you.

Commit pushed to master at https://github.com/mdn/kumascript https://github.com/mdn/kumascript/commit/22e22756efebc52b0a3eec411be38ed9f0182fac Bug 1363667: add RTCRtpTransceiver, RTCRtpContributingSource, and RTCRtpSynchronizationSourc to WebRTC Group (#575) Adds three interfaces to the WebRTC API: RTCRtpTransceiver, RTCRtpContributingSource, and RTCRtpSynchronizationSource.
Thanks, Sheppy. It all looks good to me with two caveats. First, our implementation of RTCRtpSynchronizationSource has a limitation where it does not yet contain an audioLevel in all cases. That field is only present when the audio level is provided in the RTP header. Second, the the Transceiver work was mainly done in bug 1290948, by Byron. There is also the open bug 1258409.
