After a change of priorities last year, the launch unfortunately didn't happen. But we are now ready to ship and are targeting M111. The API that would be launched is: RTCRtpEncodingParameters extension scalabilityMode ( https://w3c.github.io/webrtc-svc /#dom-rtcrtpencodingparameters-scalabilitymo

At the moment, I think we can safely ship: - RTCRtpEncodingParameters extension scalabilityMode ( https://w3c.github.io/webrtc-svc/#dom-rtcrtpencodingparameters-scalabilitymode ) We have an open discussion on whether or not to ship this part on senders (we've decided not to ship it on receivers):

Hi Bernard, Can you clarify what the consensus is on RTCRtpEncodingParameters's scalabilityMode member? That remains in https://w3c.github.io/webrtc-svc/, but will it be removed? Meanwhile, referenceScaling is only partly spec'd, there's no IDL for it but a link to https://github.com/w3c/media-cap

Hi Harald, Can you spell out what the uncontroversial parts of this would be? Looking at the IDL in https://w3c.github.io/webrtc-svc/ it looks like it's all about modes. My guess is that it's RTCRtpEncodingParameters's scalabilityMode, but is that right? Best regards, Philip On Mon, Dec 6, 2021

The scalability modes (being able to set them) are the point of the launch. Figuring out which of the desired ones are available seems like it would be a requirement. On Mon, Oct 25, 2021 at 9:32 PM Fernando Serboncini wrote: > It seems they are asking for a delay on Chrome launching this until

It seems they are asking for a delay on Chrome launching this until the WebRTC WG makes a decision on it. It's not clear from the issue that there's a consensus on the right approach there. Did you consider launching things separately and delaying the scalability modes? Or does the whole launch ma

Note - the change request from WebKit ( https://github.com/w3c/webrtc-svc/issues/49) involves removing the list of scalability modes from the codec information in WebRTC and instead using the MediaCapabilities API with the "webrtc" usage to detect whether a given scalability mode is available or no
