Module rtp_transceiver 

RTP Media API

This module provides the RTCRtpTransceiver, which represents a permanent pairing of an RTCRtpSender and an RTCRtpReceiver, along with shared state.

Overview

A transceiver manages bidirectional media exchange for a single media type (audio or video). It combines:

• An RTP sender for outgoing media
• An RTP receiver for incoming media
• Shared state including direction, mid, and codec preferences

Examples

Adding a transceiver from a track

let mut peer_connection = RTCPeerConnectionBuilder::new().build()?;

// Add a transceiver for sending audio
let init = RTCRtpTransceiverInit {
    direction: RTCRtpTransceiverDirection::Sendrecv,
    ..Default::default()
};

let sender_id = peer_connection
    .add_transceiver_from_track(audio_track, Some(init))?;

println!("Added sender with ID: {:?}", sender_id);

Adding a transceiver by media kind

let mut peer_connection = RTCPeerConnectionBuilder::new().build()?;

// Add a video transceiver for receiving only
let init = RTCRtpTransceiverInit {
    direction: RTCRtpTransceiverDirection::Recvonly,
    ..Default::default()
};

let receiver_id = peer_connection
    .add_transceiver_from_kind(RtpCodecKind::Video, Some(init))?;

println!("Added receiver with ID: {:?}", receiver_id);

Controlling transceiver direction

let mut peer_connection = RTCPeerConnectionBuilder::new().build()?;

// Iterate through transceivers and change direction
for transceiver_id in peer_connection.get_transceivers() {
    // Access the transceiver through peer_connection's internal methods
    // Note: Direct transceiver access may be internal API
    // This demonstrates the concept - actual usage depends on your API design
}

Setting codec preferences

let mut peer_connection = RTCPeerConnectionBuilder::new().build()?;

// Codec preferences would be set through peer connection methods
// The exact API depends on your implementation
