Hello. Thanks for your feedback!

I have noticed, that Firefox throws an Error when type "webrtc" is used:

TypeError: MediaCapabilities.encodingInfo: 'webrtc' (value of 'type' member of MediaEncodingConfiguration) is not a valid value for enumeration MediaEncodingType.

It will only work in Firefox with type "transmission".

Tested with Firefox version 110.0.1.

I'm updating the docs with this extra info.

Can you confirm that transmission is not working on Chrome?

[opusonline]

Chrome 111.0.5563.64 throws the following Error:

TypeError: Failed to execute 'encodingInfo' on 'MediaCapabilities': Failed to read the 'type' property from 'MediaEncodingConfiguration': The provided value 'transmission' is not a valid enum value of type MediaEncodingType.

Even back until Chrome 101.0.4951.41, this Error is shown.

Also Safari (15.6.1 and 16.1) is throwing a TypeError with message "Type error" when encodingInfo() is called with type transmission.

Thank you, so the new wording in #25230 is correct.

This looks good to me, thank you for taking care!

I've noticed a little typo at the type webrtc description:

uses transmission instad.

instad is missing an "e", so it should be instead.

Best regards!
