Description Dan 2020-07-25 10:17:34 PDT

Support for qpSum in WebRTC stats was added in https://bugs.webkit.org/show_bug.cgi?id=170060, but it seems like the value is always 0.

Created a simple repro: https://codepen.io/dbriggs/pen/wvMLREG.

Comment 3 Dan 2020-07-30 12:12:41 PDT

I noticed in the original change that qpSum was being reset to 0 immediately after being set to the correct value http://trac.webkit.org/browser/webkit/trunk/Source/WebCore/Modules/mediastream/libwebrtc/LibWebRTCMediaEndpoint.cpp?rev=214368#L273.

Not sure if that was changed at some point later though!
