Installation

$ pip install livekit

Connecting to a room

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

    # 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)

    video_stream = None

    # 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:
            nonlocal video_stream
            video_stream = livekit.VideoStream(track)

            async for frame in video_stream:
                # received a video frame from the track, process it here
                pass

    await room.run()
