In order to receive a SpeakersChanged event, containing a specific remote participant, do you have to be subscribed to his microphone publication?

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

What if i don't want to include in that speaking event remote participants which i am not subscribed to their microphone publication?

If you want to exclude remote participants from the SpeakersChanged event when you're not subscribed to their microphone publication, you can simply filter the event data based on subscription status. Here’s a straightforward way to do that: 1. Keep Track of Subscriptions: Use the

TrackPublished

and

TrackSubscribed

events to manage microphone subscriptions. For instance, subscribe to a participant’s microphone track as soon as it’s published. 2. Filter Active Speakers: When the

ActiveSpeakersChanged

event fires, filter out participants who don’t have an active microphone subscription. You can check each participant’s microphone track subscription status to do this. Here’s a simple example to get you started:

// Keep track of participants with subscribed microphone tracks
const subscribedMicParticipants = new Set();

// Handle track subscriptions
room.on(RoomEvent.TrackSubscribed, (track, publication, participant) => {
    if (participant.isRemote && track.source === Track.Source.Microphone) {
        subscribedMicParticipants.add(participant);
    }
});

room.on(RoomEvent.TrackUnsubscribed, (track, publication, participant) => {
    if (participant.isRemote && track.source === Track.Source.Microphone) {
        subscribedMicParticipants.delete(participant);
    }
});

// Filter speakers based on microphone subscription
room.on(RoomEvent.ActiveSpeakersChanged, (speakers) => {
    const filteredSpeakers = speakers.filter(participant => {
        if (participant.isLocal) return true;
        return subscribedMicParticipants.has(participant);
    });
    // Use filteredSpeakers in your application
});

This way, you’ll only include participants with subscribed microphone tracks in the SpeakersChanged event. Hope this helps make your app feel more connected and responsive! Sources: JavaScript & React Components | livekit/livekit_composite | DeepWiki | Subscribing to tracks | LiveKit Docs
