Standards information
Dictionary
| Member | Type | Description |
|---|---|---|
| clockRate | unsigned long | Codec clock rate expressed in Hertz, null if unset. |
| maxptime | unsigned long | The maximum packetization time supported by the RTCRtpReceiver. |
| name | DOMString | The MIME media type. Valid types are listed in [IANA-RTP-2]. The name MUST always be provided. |
| numChannels | unsigned long | The number of channels supported (e.g. stereo). If unset for audio, use the codec default. For video, this will be unset. |
| parameters | Dictionary | Codec-specific parameters available for signaling. |
| payloadType | payloadType | The value that goes in the RTP Payload Type Field [RFC3550]. The payloadType MUST always be provided. |
| ptime | unsigned long | The duration of media represented by a packet in milliseconds for the RTCRtpSender. If unset, the RTCRtpSender may select any value up to maxptime. |
| rtcpFeedback | sequence<RTCRtcpFeedback> | Transport layer and codec-specific feedback messages for this codec. |
Note The capabilities for commonly implemented codecs described in Edge Codec Capabilities, are also used as codec parameters, with RTCRtpCodecCapability.parameters of the receiver used as RTCRtpCodecParameters.parameters of the sender, and RTCRtpCodecCapability.parameters of the sender used as RTCRtpCodecParameters.parameters of the receiver, with the Property Name and Values unchanged.
