To prevent placeholder tiles from generating for specific participants when using the VideoConference React component, you need to adjust the

withPlaceholder

property in your

useTracks

hook configuration. For example, set

withPlaceholder: false

for the desired sources:

{`
const tracks = useTracks(
  [
    { source: Track.Source.Camera, withPlaceholder: false },
    { source: Track.Source.ScreenShare, withPlaceholder: false },
  ],
  { updateOnlyOn: [RoomEvent.ActiveSpeakersChanged], onlySubscribed: false }
);
`}

This configuration will prevent placeholder tiles from being generated for those sources across all participants. If you need to prevent placeholders only for specific participants (not globally per track source), a custom implementation would be required, as the built-in logic applies the placeholder setting to all participants uniformly. For details about placeholder logic and further customization directions, see the guidance above. Sources: packages/react/src/hooks/useParticipantTile.ts
