Hello, we’re just looking into Zoom Web Video SDK to potentially migrate from using Jitsi.  
I know that currently multiple video streams on Firefox are not supported, as declared on the marketplace and mediaStream.isSupportMultipleVideos() returns false. But will it be supported any time soon?

In [this thread](https://devforum.zoom.us/t/video-sdk-web-version-1-0-3/49113) it was said that you would support multiple videos once SharedArrayBuffer and SIMD were supported in Firefox. I think that they are [both](https://groups.google.com/g/mozilla.dev.platform/c/yLQxaBp9-o8/m/zwsm7rikAgAJ?pli=1) supported now?

The example React app currently only displays a single video (the current active speaker). Are there plans to demonstrate the ability to show multiple video streams by using multiple video elements rather than a single canvas? Or even a video for self view? Is this possible? On Firefox it doesn’t seem to show my own camera even if I am the active speaker.

Thanks for any insight into these.

Hey @jessian

Thanks for your feedback.

We don’t restrict the browsers, the value of `mediaStream.isSupportMultipleVideos()` depends on the feature detection.  
For the second item, we will improve the demo app soon.

Thanks  
Vic
