Tips for transmitting media stream from Angular code to Facemesh.js

Is there a way for me to replace the camera function and pass my own mediastream from another angular module? Src:

const customMediaStream = getCustomMediaStream(); // Some function to get custom media stream
const camera = new Camera(videoElement, {
  onFrame: async () => {
    await faceMesh.send({image: customMediaStream});
  },
  width: 1280,
  height: 720
});
camera.start();

I am facing issues in passing mediastream to faceMesh.send() when trying to remove the camera function.

Answer №1

MediaPipe FaceMesh has the capability to analyze videos with HTMLVideoElement (using a process of transferring frames to canvas and then extracting pixels for analysis), eliminating the need for manual handling.

However, real-time per-frame events are not supported by default in JavaScript specifications - this functionality is provided by the Camera wrapper.

I won't provide code examples, but here's the workflow you should follow:

  1. Send data using faceMesh.send
  2. Wait for the results to be returned
  3. Process the results and send another set of data using faceMesh.send
