To load a placeholder Simli avatar when a LiveKit room loads, you can customize the

ParticipantTile

component to display a default avatar image. According to LiveKit documentation, you can implement your own version of the

ParticipantTile

and replace the default placeholder with your desired avatar image. You can use the

useParticipantTile

hook to manage the participant's state and logic. Would you like more detailed guidance on implementing this customization?

@millions-hair-24956 please provide more details on having an avatar loaded in the room

To load a custom avatar in a LiveKit room, you can modify the

ParticipantTile

component to display a specific avatar image. Here's a step-by-step guide on how to achieve this: 1. Customize the ParticipantTile: According to LiveKit documentation, the

ParticipantTile

component is used to display a participant's video or avatar. You can create a custom version of this component to include your avatar image. 2. Use the useParticipantTile Hook: The useParticipantTile hook provides the necessary props to render a participant tile. You can use this hook to manage the participant's state and apply your custom avatar. 3. Implement Custom Avatar Logic: In your custom

ParticipantTile

, replace the default placeholder with your avatar image. You can use the

trackRef

property to determine if a video track is available. If not, display the avatar image. Here's a basic example of how you might implement this in a React component:

import React from 'react';
import { useParticipantTile } from '@livekit/components-react';

const CustomParticipantTile = ({ participant }) => {
  const { elementProps, trackRef } = useParticipantTile(participant);

  return (
    <div {...elementProps}>
      {trackRef ? (
        <video ref={trackRef} autoPlay playsInline />
      ) : (
        <img src="path/to/your/avatar.png" alt="Avatar" />
      )}
    </div>
  );
};

export default CustomParticipantTile;

4. Integrate with LiveKitRoom: Use your

CustomParticipantTile

within the

LiveKitRoom

component to ensure it is rendered for each participant. Would you like more information on any specific part of this process? Sources: - LiveKit documentation - useParticipantTile 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

@millions-hair-24956 can I load a place holder video avatar?

It seems likely that you can load a placeholder video avatar in a LiveKit room by publishing a pre-recorded video track as a placeholder. Here's a general approach to achieve this: 1. Create a Local Video Track: Use the LiveKit SDK to create a local video track from a pre-recorded video file. This can be done by capturing the video stream from a video element in your application. 2. Publish the Video Track: Once you have the video track, you can publish it to the LiveKit room using the

publishTrack

method on the local participant. 3. Use a Video Element: In your React component, use a video element to play the pre-recorded video. Capture this video stream and create a local video track from it. Here's a basic example of how you might implement this in a React component:

import React, { useEffect, useRef } from 'react';
import { createLocalVideoTrack } from 'livekit-client';

const PlaceholderVideoAvatar = ({ room }) => {
  const videoRef = useRef(null);

  useEffect(() => {
    const setupVideoTrack = async () => {
      if (videoRef.current) {
        const stream = videoRef.current.captureStream();
        const videoTrack = await createLocalVideoTrack({ stream });
        room.localParticipant.publishTrack(videoTrack);
      }
    };

    setupVideoTrack();
  }, [room]);

  return (
    <video ref={videoRef} src="path/to/your/video.mp4" autoPlay loop muted />
  );
};

export default PlaceholderVideoAvatar;

This example assumes you have a video file available at

path/to/your/video.mp4

. The video is played in a loop and muted, and its stream is captured to create a local video track that is published to the room.

@millions-hair-24956 when my talking avatar is pushed from the backend will it replace the video placeholder or is there a better way to implement this

It seems likely that when your talking avatar is pushed from the backend, it can replace the video placeholder by updating the video track associated with the participant. Here's a general approach to implement this: 1. Initial Placeholder Setup: Initially, you can publish a placeholder video track as described in the previous response. This track acts as a placeholder until the actual avatar stream is ready. 2. Backend Avatar Stream: When the backend is ready to push the talking avatar stream, it can publish a new video track to the room. This can be done using the LiveKit server SDKs to manage track publications. 3. Replace Placeholder with Avatar: On the client side, listen for track updates. When the new avatar video track is published, you can replace the existing placeholder track with the new one. This can be achieved by unsubscribing from the placeholder track and subscribing to the new avatar track. Here's a basic example of how you might handle this in a React component:

import React, { useEffect } from 'react';
import { useParticipantTracks } from '@livekit/components-react';

const AvatarHandler = ({ participant }) => {
  const { videoTracks } = useParticipantTracks(participant);

  useEffect(() => {
    // Logic to handle track updates
    const handleTrackUpdate = () => {
      // Unsubscribe from placeholder and subscribe to new avatar track
      videoTracks.forEach((track) => {
        if (track.isPlaceholder) {
          track.setSubscribed(false);
        } else {
          track.setSubscribed(true);
        }
      });
    };

    handleTrackUpdate();
  }, [videoTracks]);

  return null; // Render logic for video tracks
};

export default AvatarHandler;

This example uses the

useParticipantTracks

hook to manage video tracks and replace the placeholder with the avatar track when available. Would you like more detailed guidance on any specific part of this process?
