the prolem is disconnection i want to dissconnected room wen no one prasent

Hey there! If you want to disconnect a LiveKit room when no one’s in it, here are a couple of easy ways to do that: 1. Server-side Room Deletion: You can use the

DeleteRoom

API to delete the room, which will disconnect everyone inside. Here’s a quick example in Go:

_, _ = roomClient.DeleteRoom(context.Background(), &livekit.DeleteRoomRequest{
    Room: "myroom",
})

2. Automatic Disconnection: Set the room’s

EmptyTimeout

so it automatically closes after being empty for a bit. This way, the room shuts down when no participants are around. Both of these options help make sure the room closes properly and frees up resources when it’s empty. If you want a hand setting any of this up, just let me know—I’m happy to help!

no the thing is want to store transcription in databse with custom function

Here’s a friendly guide to help you store LiveKit transcription data in a database using a custom function: 1. Access Transcription Data: Start by listening for the

RoomEvent.TranscriptionReceived

event in your app to grab those transcription segments as they come in. 2. Set Up Database Schema: You’ll want to create a database schema to hold your transcription data. For example, in SQLite:

CREATE TABLE participants (
    id TEXT PRIMARY KEY,
    identity TEXT NOT NULL,
    name TEXT
);

CREATE TABLE transcriptions (
    id TEXT PRIMARY KEY,
    participant_id TEXT NOT NULL,
    segment_id TEXT NOT NULL,
    text TEXT NOT NULL,
    language TEXT,
    final BOOLEAN,
    first_received_time INTEGER,
    last_received_time INTEGER,
    FOREIGN KEY(participant_id) REFERENCES participants(id)
);

3. Implement Custom Function: Next, write a function that processes and saves the transcription data to your database. Here’s an example in JavaScript: `async function storeTranscription(transcription) { const db = new sqlite3.Database('transcriptions.db'); await db.run(

CREATE TABLE IF NOT EXISTS participants (id TEXT PRIMARY KEY, identity TEXT NOT NULL, name TEXT)

); await db.run(

CREATE TABLE IF NOT EXISTS transcriptions (id TEXT PRIMARY KEY, participant_id TEXT NOT NULL, segment_id TEXT NOT NULL, text TEXT NOT NULL, language TEXT, final BOOLEAN, first_received_time INTEGER, last_received_time INTEGER, FOREIGN KEY(participant_id) REFERENCES participants(id))

); const participantStmt = db.prepare('INSERT OR IGNORE INTO participants VALUES (?, ?, ?)'); participantStmt.run(transcription.participant_identity, transcription.participant_identity, transcription.participant?.name || ''); participantStmt.finalize(); const transcribeStmt = db.prepare(

INSERT OR REPLACE INTO transcriptions VALUES (?, ?, ?, ?, ?, ?, ?, ?)

); for (const segment of transcription.segments) { transcribeStmt.run(transcription.track_sid, transcription.participant_identity, segment.id, segment.text, segment.language, segment.final, segment.start_time, segment.end_time); } transcribeStmt.finalize(); db.close(); }` 4. Handle Real-Time Data: Set up event listeners to catch and process transcription data as it arrives:

room.on(RoomEvent.TranscriptionReceived, (event) => {
    const transcription = new Transcription(event.participant.identity, event.track_sid, event.segments);
    storeTranscription(transcription);
});

5. Best Practices: ◦ Wrap your database actions in transactions to keep things consistent. ◦ Add retry logic to handle any hiccups during database operations. ◦ Use

INSERT OR IGNORE

or

INSERT OR REPLACE

to gracefully manage duplicates. If you’d like, I’m here to help you tweak this for your specific database setup or answer any questions you have along the way. Just let me know! Sources: lib/src/context/transcription_context.dart | Sending text | LiveKit Docs

how to check if any participent present or not

Hey there! If you want to check whether there are any participants in a LiveKit room, here are a few easy ways to do it: 1. Server-Side: You can use the

RoomServiceClient

to get a list of participants in a room. Here's a quick example:

const roomService = new RoomServiceClient(livekitHost, apiKey, apiSecret);
const participants = await roomService.listParticipants(room);
const participantCount = participants.length;

2. Client-Side: On the client side, you can check the participants through the SDK’s room state. For instance, in Python:

if room.num_participants > 0:
    print("There are participants in the room")

3. Real-Time Updates: Want to stay updated as participants join or leave? You can subscribe to participant events. Here’s how you might do it in React Native:

const participants = useParticipants();
useEffect(() => {
  setParticipantCount(participants.length);
}, [participants]);

4. Command-Line Interface (CLI): If you prefer the command line, the LiveKit CLI lets you list participants in a room like this:

lk room participants list --room <room-name>
