📹🎙️🐍 Python Client SDK for LiveKit

The Livekit Python Client provides a convenient interface for integrating Livekit's real-time video and audio capabilities into your Python applications. With this library, developers can easily leverage Livekit's WebRTC functionalities, allowing them to focus on building their AI models or other application logic without worrying about the complexities of WebRTC.

Official LiveKit documentation: https://docs.livekit.io/

Installation

$ pip install livekit

Connecting to a room

async def main():
    room = livekit.Room()

    # participants and tracks that are already available in the room
    # participant_connected and track_published events will *not* be emitted for them
    for participant in room.participants.items():
        for publication in participant.tracks.items():
            print("track publication: %s", publication.sid)

    @room.on("participant_connected")
    def on_participant_connected(participant: livekit.RemoteParticipant):
        logging.info(
            "participant connected: %s %s", participant.sid, participant.identity)

    async def receive_frames(stream: livekit.VideoStream):
        async for frame in video_stream:
            # received a video frame from the track, process it here
            pass

    # track_subscribed is emitted whenever the local participant is subscribed to a new track
    @room.on("track_subscribed")
    def on_track_subscribed(track: livekit.Track, publication: livekit.RemoteTrackPublication, participant: livekit.RemoteParticipant):
        logging.info("track subscribed: %s", publication.sid)
        if track.kind == livekit.TrackKind.KIND_VIDEO:
            video_stream = livekit.VideoStream(track)
            asyncio.ensure_future(receive_frames(video_stream))

    # By default, autosubscribe is enabled. The participant will be subscribed to
    # all published tracks in the room
    await room.connect(URL, TOKEN)
    logging.info("connected to room %s", room.name)

Examples

• Facelandmark: Use mediapipe to detect face landmarks (eyes, nose ...)
• Whisper: Transcribe an audio track using OpenAI whisper
• Basic room: Connect to a room
• Publish hue: Publish a rainbow video track
• Publish wave: Publish a sine wave
