The WebRTC APIs have long enabled sending and receiving realtime media peer-to-peer with a streamlined control interface, but with limited ability to tune how media is encoded and interacts with the network. While APIs such as WebCodecs have begun to allow users low-level access to the browser's built-in encoders and decoders, there is still no API to allow similar levels of access to the low-latency peer-to-peer network transports like those used within an RTCPeerConnection.

The RtcTransport API aims to enable applications to directly utilize peer-to-peer datagram based transport for realtime media, controlling the details of congestion control and allowing arbitrary media encodings and formats. The current proposal is an evolution of the RTP-focussed transport discussed in a breakout session at TPAC 2024.
