hi! there’s no built in way in the components framework to retrieve tracks based on publication time. Could you elaborate a bit on your usecase, maybe there are some workarounds to achieve what you’re trying to do

So i have usecase where i want to show only one camera/screen share track. 1. User 1 and User 2 is there and User 1 is rendring its video . When the user 2 try to start its video rendenring the user1 video rendring should stop and user 2 video should render only

thanks, I guess one option would be to track the order of tracks within a custom hook that wraps

useHooks

and returns the “newest” one only.

The order of tracks is not consistent. Let's suppose we have an array of camera tracks 1. User 1 starts camera. CameraArray[user1]. If I close it the camera track of that users doesn't remove from the array.it is working good in terms of screen share

you’ll want to manage the order yourself with something like (pseudo code)

useOrderedTracks() {
  const [orderedTracks, setOrderedTracks] = React.useState([]);
  const unOrderedTracks = useTracks();
  unOrderedTracks.forEach(track => if(!orderedTracks.includes(track)) setOrderedTracks(tracks => [...tracks, track]));
  return orderedTracks[orderedTracks.length-1];
}

Let me see. Thank you for your suggestion

no problem, I think the solution is very incomplete right now, sounds like you also want to add handling for

mute

events here, so that you always re-order the array in a way that the latest track that has been

unmuted

is chosen

Did you know.I you use LiveKitURl component in NExt js and inside this get the room from const room =useRoom() and attach the events. like room.on(RoomEvent.trackPublishesd,(track)=>{console.log(track}) why these events dont work. Any idea

two things here: on initial room connection no

trackPublished

events are emitted for publications that are already present on the room. You’ll have to loop over

room.participants.foreach(p => p.tracks.forEach))

to handle those. For locally published tracks you’ll additionally want to handle

RoomEvent.LocalTrackPublished

, too

room.participants.foreach(p => p.tracks.forEach)) in this i will get 4 camera tracks let's suppose how to distinguish which camera track is active or not. Becuase if the camera track is inactive it doesn't remove from the camera tracks array. Whereas schreenshare tracks got removed when you stop sharing. so at least we know if the screen share contains only active tracks

you can check whether or not they are muted by looking at trackPub.isMuted

Got the things. Thanks for the help.
