Remove RTCRtpCodecCapability.kind

[ibc]

If we go (as per last WebRTC WG meeting) with full MIME type/subtype for codec names ("audio/opus", "video/VP8", etc), we should remove the RTCRtpCodecCapability.kind parameter because the RTCRtpCodecCapability.name already includes the MIME type ("audio", "video").

At the WEBRTC WG meeting, it was pointed out that getCapabilities("depth") might return "video/vp8", so that kind and the MIME media type are not necessarily be the same.

[ibc]

Can the RtpReceiver constructor be called with "depth" as kind value?

[aboba]

If the implementation supports "depth" I believe it would have to be allowed. See the W3C Depth Capture specification: https://w3c.github.io/mediacapture-depth/

Let's close this issue.
