Hi,  
I’m trying to implement the video SDK in my Angular App.  
I started by turning purejs demo into Angular.  
In my situation, I have two canvas :

- One to display my video
- One to display participants video

When my cam is activated, other participants can see my video in their second canvas, but I don’t see my video in my first canvas. When they show their video I can see it in the second canvas.

I tried to add the following tag in my index.html :  
`<meta http-equiv="origin-trial" content="TOKEN">`

And after that I tried to add in my angular.json :

```auto
"headers": {
              "Cross-Origin-Opener-Policy":"same-origin",
              "Cross-Origin-Embedder-Policy":"require-corp"
}

```

Both attempt are not solving the problem.

Any idea ?

Hey @ALanois ,

What happens when you run `typeof SharedArrayBuffer ==='function'` in the browser console?
