Video broken on web client in new versions of Chrome

[covegeary]

In Google Chrome 94.0.4603.0, video capture appears to be broken. Only a black rectangle is visible when I turn on "Video," both in my view of the web client and on the receiving end for other Zoom participants.

The javascript log in the developer console repeatedly cites, "framereader read null frame!" For example, one short log file is copied below (text attachments are not allowed; sorry for the long message).

The bug does not appear in the stable version of Chrome, such as  92.0.4515.159; nor in Firefox. This is all tested in Arch Linux. Unfortunately, I need the newer Chrome in order to support other features for my platform that haven't yet trickled down.

Could this be due to Chrome's updates to SharedArrayBuffer support? In any case—hope this is the proper place for a bug report and to receive support.

Hi @covegeary 

This is not the official way to get support from Zoom, but I know there is a web client release scheduled for this weekend. While it doesn't mention it specifically, I know there are some included changes to address the updates within Chrome.
