Hey @kvr

Thanks for your feedback.

Did you enable the Cross-Origin Isolated on your site? If the SharedArrayBuffer is unavailable on the site, only one video can be rendered on the same canvas unless enabled the enforceMultipleVideos option in the init method.

Thanks
Vic

I had this problem when clearing the canvas before calling stopRender video, then I didn’t remove the canvas but just set display:none

Anyway, I used one canvas per user and all canvas was paused when I had 5-6 participants. For now, I just use only one canvas, rendering by X, Y and it works fine.

If isSupportMultipleVideos returns false, please add these lines to nginx header

Cross-Origin-Opener-Policy: same-origin
Cross-Origin-Embedder-Policy: require-corp

or use this link to generate a token and add this line to your index

	<meta http-equiv="origin-trial" content="token">

That was my case, hope it helps someone

Ver: 1.2.7
Env: VueJS
