- setCodecPreferences
- - Setting codecs to an empty sequence resets codec preferences to any
- default value.
-
- - The codecs sequence passed into setCodecPreferences can only contain
- codecs that are returned by RTCRtpSender.getCapabilities(kind) or
- RTCRtpReceiver.getCapabilities(kind), where kind is the kind of the
- RTCRtpTransceiver on which the method is called. Additionally, the
- RTCRtpCodecParameters dictionary members cannot be modified. If
- codecs does not fulfill these requirements, the user agent MUST throw
- an InvalidModificationError.
