如何获取 WebRTC 实验统计数据

Question

I am trying to get some statistics about a WebRTC live stream.

On chrome://webrtc-internals I am able to see some statistics marked experimental (with a * ), that I can not find using getStats method. That includes freezeCount , pauseCount , totalFreezesDuration , totalPausesDuration , totalFramesDuration , sumOfSquaredFramesDuration

Do you know how to get those statistics using JavaScript ?

Note: I found this W3 draft of a potential specification that describe those statistics, but cannot find any example on the web.

Note: I am using Google Chrome

Note: According to this commit , those metrics where introduce in February 2019 so quite long ago...

Answer 1

These values are not available to Javascript/getStats because they're not standardized. If you consider them useful, file an issue on https://github.com/w3c/webrtc-provisional-stats and provide a compelling use-case.
