Video is not working in Chrome 94

When a participant tries to join a video meeting, he is not able to see his own video and fails to send the video to the other participants. This is only happening in Chrome browser (Version 94.0.4606.61 (Official Build) (64-bit) and Version 94.0.4606.71 (Official Build) (64-bit)). It works perfectly fine in chrome browser (Version 93.0.4577.63 (Official Build) (64-bit)) and in Firefox (version 92.0.1) on any operating system.

Browser Console Error

TypeError: Failed to execute 'copyTo' on 'VideoFrame': rect.y 5 is not sample-aligned in plane 1.

Hey @mitesh.gandhi ,

Instead of 'Global' can you try using '' . That should fix the issue! :slight_smile:


Hey Tommy,
We replaced ‘Global’ with ‘’, but we are still getting the same error “Failed to execute ‘copyTo’ on ‘VideoFrame’: rect.y 5 is not sample-aligned in plane 1.”


@tommy fwiw when I click that link for ‘’ I get an 403 error response (AccessDenied).

Hey @mitesh.gandhi ,

Can I ask for steps to reproduce this issue? It seems like this could be an issue with how you are rendering the video stream.

I cannot reproduce this error with our sample app: GitHub - zoom/sample-app-videosdk: zoom videosdk web demo


Hey @victor.aprea ,

That is correct. You need to pass in that url like I mentioned above, and the SDK will grab the public assets itself. :slight_smile:


Hey Tommy,
The issue is fixed. The error was due to configurationOptions (width and height) being passed as a parameter to the method stream.startVideo.

captureOptions = {
    captureWidth: this.config.width,
    captureHeight: this.config.height
await stream.startVideo(captureOptions)
// changing to below code fixed it
await stream.startVideo()

Thanks for your help.
