Thanks for reaching out, Rajendra. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

To allow subscribing to a track for specific identities in a LiveKit room, you can use Track Subscription Permissions. This feature lets you restrict access to tracks on a per-participant basis. Here's how you can implement it: • Set

allParticipantsAllowed

false

to enable restrictions. • Define permissions for specific participants using their identity or SID. • Grant access to all tracks or specific tracks for each participant. For example, in the JavaScript SDK:

Copy code

// Allow only specific participants to subscribe
localParticipant.setTrackSubscriptionPermissions(
  false, // allParticipantsAllowed: false to enable restrictions
  [
    {
      participantIdentity: "allowed-participant-1",
      allowAll: true // Allow this participant to subscribe to all tracks
    },
    {
      participantIdentity: "allowed-participant-2", 
      allowedTrackSids: ["specific-track-id"] // Allow only specific tracks
    }
  ]
);

For other SDKs like Swift or Go, similar methods are available to set these permissions. To list the current tracks in a LiveKit room, you can use the following approaches: • Using the useTracks Hook (React/React Native):

Copy code

import { useTracks } from '@livekit/react-native';
import { Track } from 'livekit-client';

const tracks = useTracks([Track.Source.Camera]); // Get all camera tracks

• Accessing Tracks Directly from Participants:

Copy code

// For local participant
const localTracks = Array.from(room.localParticipant.tracks.values());

// For remote participants
Array.from(room.participants.values()).forEach((participant) => {
  const participantTracks = Array.from(participant.tracks.values());
});

These methods allow you to manage and list tracks effectively in your LiveKit room. Sources: localparticipant.go | pkg/rtc/room.go | src/room/participant/LocalParticipant.ts | Sources/LiveKit/Types/ParticipantTrackPermission.swift | docs/interfaces/RoomState.html

Hey there! Let's talk about setting track subscription permissions in LiveKit using Python. Think of this like controlling who gets to see and hear your tracks in a room - pretty cool, right? Here's a friendly guide to help you out: • Allow All Participants (Default Behavior):

Copy code

room.local_participant.set_track_subscription_permissions(
    allow_all_participants=True
)

• Restrict All Participants:

Copy code

room.local_participant.set_track_subscription_permissions(
    allow_all_participants=False
)

• Grant Specific Permissions:

Copy code

from livekit import rtc

room.local_participant.set_track_subscription_permissions(
    allow_all_participants=False,
    participant_permissions=[
        rtc.ParticipantTrackPermission(
            participant_identity="allowed-user-identity",
            allow_all=True,
        )
    ],
)

• Grant Permissions to Specific Tracks:

Copy code

room.local_participant.set_track_subscription_permissions(
    allow_all_participants=False,
    participant_permissions=[
        # Allow one participant to subscribe to all tracks
        rtc.ParticipantTrackPermission(
            participant_identity="user1",
            allow_all=True,
        ),
        # Allow another participant to subscribe only to specific tracks
        rtc.ParticipantTrackPermission(
            participant_identity="user2",
            allowed_track_sids=["track_sid_1", "track_sid_2"],
        )
    ],
)

Let me break down the

ParticipantTrackPermission

class for you: • `participant_identity`: Who this permission is for • `allow_all`: Give access to all tracks (this is the big boss setting) • `allowed_track_sids`: Specific tracks you want to share By default, everyone can tune into your tracks. But with these settings, you can be super selective about who sees or hears what. Pretty neat, right? Now you can control your room like a pro! 😊 Sources: livekit-rtc/livekit/rtc/track_publication.py | Publishing tracks | LiveKit Docs
