Bug 267696 – Missing WebRTC stats in Safari

• Status: RESOLVED
• Resolution: FIXED
• Component: WebRTC

[Kaustav]

These following important WebRTC stats are missing in Safari. Could you please add these?

inbound-rtp: qpSum, rtxSsrc, fecSsrc, decoderImplementation
outbound-rtp: rtxSsrc, scalabilityMode, encoderImplementation
data-channel: dataChannelIdentifier
local-candidate: foundation, usernameFragment, tcpType
remote-candidate: foundation, usernameFragment, tcpType

[Kaustav]

two more stats

local-candidate: relayProtocol
remote-candidate: relayProtocol

Bonus points for the rest of the FEC stats (already implemented in Chromium's libWebRTC)

inbound-rtp: fecBytesReceived, fecPacketsReceived, fecPacketsDiscarded

For qpSum and scalabilityMode, we need to pipe the info of the remote decoder/encoder to libwebrtc. I filed https://bugs.webkit.org/show_bug.cgi?id=268155 to keep track of this one.

I do not think we want to expose decoderImplementation/encoderImplementation at this point. Media Capabilities can be used to check whether it should be powerEfficient or not, which should in general match whether VTB is used or not.
