🔌 The whole WebRTC API is bound. Every interface, every method, every dictionary: all 154 binding issues of the tracker are done, and the API goes beyond them

🎞 Media processing that not every browser ships yet: MediaStreamTrackProcessor, VideoTrackGenerator and MediaStreamTrackGenerator, with the VideoFrame and AudioData of WebCodecs

🔐 WebRTC Encoded Transform: the encoded frames of senders and receivers in Python with RTCRtpScriptTransform, and end-to-end encryption with SFrame

🎥 H.264 without bundling it: VideoToolbox on macOS, offered by default, and Cisco's OpenH264 binary on request elsewhere

🚀 Field trials and WARP: DTLS 1.3, SNAP and SPED cut round trips off connection setup

⚡ libwebrtc M152, pre-built wheels for Linux (x86_64 and aarch64), macOS and Windows, CPython 3.9 – 3.15, free-threaded 3.14t and 3.15t too

🧪 The public API follows the WebIDL of the specifications and runs the original web-platform-tests

📚 Fully reworked docs website: a new theme, guides, examples and the full API reference

What is bound, by specification:

  • WebRTC: RTCPeerConnection, RTCDataChannel, RTCRtpTransceiver, RTCRtpSender, RTCRtpReceiver, RTCDtlsTransport, RTCIceTransport, RTCSctpTransport, RTCDTMFSender, RTCCertificate, RTCIceCandidate, RTCSessionDescription, with every method, attribute, event and dictionary
  • WebRTC Extensions: standalone RTCIceTransport, RTP header encryption, and more
  • WebRTC Statistics: 19 typed stats objects in RTCStatsReport
  • WebRTC Encoded Transform: RTCRtpScriptTransform, RTCEncodedVideoFrame, RTCEncodedAudioFrame, and SFrame (RFC 9605)
  • Media Capture and Streams: MediaStream, MediaStreamTrack with constraints, settings and capabilities, and MediaDevices with a synthetic camera and microphone
  • MediaStreamTrack Insertable Media Processing: MediaStreamTrackProcessor, VideoTrackGenerator, and MediaStreamTrackGenerator
  • WebCodecs: VideoFrame and AudioData
  • Streams: ReadableStream, WritableStream and TransformStream, with piping and async iteration

In numbers: 229 public classes, 50 enums with the string values of the specifications, 18 exceptions named after their DOMException, and the camelCase names of the specifications next to the snake_case ones.
