After joining a session when I use the function [`switchCamera`](https://marketplacefront.zoom.us/sdk/custom/web/modules/stream.html#switchcamera) the camera freeze for some seconds (sometimes more than 15) with multiple `'fps error'` messages logged form `'JsMediaSDK_VideoRender.js:64'`.  
Sometimes I have the same issue when I disable and then enable again a Camera using [`stopVideo`](https://marketplacefront.zoom.us/sdk/custom/web/modules/stream.html#stopvideo) and [`startVideo`](https://marketplacefront.zoom.us/sdk/custom/web/modules/stream.html#startvideo) functions.

I am using the version v1.0.0 of the FCWSDK

Is there any workaround for this issue or should I wait for a fix?

Thanks  
Vincent

Hi @tommy,

I had this issue on a Windows 10 computer and a Mac using the Chrome browser version 87.0.4280.88 (latest).

On the Mac I am switching between the internal ‘FaceTime HD 720p’ and an external ‘C922 Pro Stream Webcam 1080p’. My webcams have different resolutions.
