Could you please add RTC event log support in Safari. Here's more info about this logging https://webrtc.googlesource.com/src/+/lkgr/logging/g3doc/rtc_event_log.md

@youenn could you please also share the instructions on how to get these logs or webrtc verbose logs from the web inspector?

[youenn fablet]

@Kaustav, at the moment, you can call gatherRTCLogs from web inspector, and pass it a callback, which will be called with the following dictionary:
dictionary RTCLogs {
    DOMString type;
    DOMString message;
    DOMString level;
    ArrayBuffer data;
    RTCPeerConnection connection;
};

type can be logs and stats currently, message is where the info is.
Once this bugs is fixed, there will be a new type named events, data is where the info will be.

thanks @youenn. And to confirm on how to enable verbose WebRTC logs, there is still only one option through the dropdown menu in settings?

This was reverted in https://bugs.webkit.org/show_bug.cgi?id=276933 due to build breakage.

Could you please re-enable this feature in Safari? RTC event logs are very useful for video quality or bandwidth estimation related investigations in WebRTC.
