Enum mediasoup::rtp_parameters::RtpCodecCapability

pub enum RtpCodecCapability {
    Audio {
        mime_type: MimeTypeAudio,
        preferred_payload_type: Option<u8>,
        clock_rate: NonZeroU32,
        channels: NonZeroU8,
        parameters: RtpCodecParametersParameters,
        rtcp_feedback: Vec<RtcpFeedback>,
    },
    Video {
        mime_type: MimeTypeVideo,
        preferred_payload_type: Option<u8>,

    },
}

Provides information on the capabilities of a codec within the RTP capabilities. The list of media codecs supported by mediasoup and their settings is defined in the supported_rtp_capabilities.rs file.

Exactly one RtpCodecCapability will be present for each supported combination of parameters that requires a distinct value of preferred_payload_type. For example:

• Multiple H264 codecs, each with their own distinct packetization-mode and profile-level-id values.
• Multiple VP9 codecs, each with their own distinct profile-id value.

RtpCodecCapability entries in the mediaCodecs array of RouterOptions do not require preferred_payload_type field (if unset, mediasoup will choose a random one). If given, make sure it’s in the 96-127 range.

Variants

Audio

Audio codec capability

Fields of Audio

mime_type: MimeTypeAudio

The codec MIME media type/subtype (e.g. ‘audio/opus’).

preferred_payload_type: Option<u8>

The preferred RTP payload type.

clock_rate: NonZeroU32

Codec clock rate expressed in Hertz.

channels: NonZeroU8

The number of channels supported (e.g. two for stereo). Just for audio. Default 1.

parameters: RtpCodecParametersParameters

Codec specific parameters. Some parameters (such as packetization-mode and profile-level-id in H264 or profile-id in VP9) are critical for codec matching.

rtcp_feedback: Vec<RtcpFeedback>

Transport layer and codec-specific feedback messages for this codec.

Video

Video codec capability

Fields of Video

mime_type: MimeTypeVideo

The codec MIME media type/subtype (e.g. ‘video/VP8’).

preferred_payload_type: Option<u8>

The preferred RTP payload type.

clock_rate: NonZeroU32

Codec clock rate expressed in Hertz.

parameters: RtpCodecParametersParameters

Codec specific parameters. Some parameters (such as packetization-mode and profile-level-id in H264 or profile-id in VP9) are critical for codec matching.

rtcp_feedback: Vec<RtcpFeedback>

Transport layer and codec-specific feedback messages for this codec.
