Sangoma Meet - What to do if I'm sharing video and others see just a black screen? (Chrome)
If you are sharing video on Google Chrome or another browser but your viewers just see a black screen, it is most likely because your hardware graphics acceleration is not disabled in the settings. There is a relatively easy fix for this that works in most cases. Here is how you disable hardware graphics acceleration on Chrome
You can skip steps 1-3 by entering chrome://settings/?search=Hardware+acceleration into the browser field in Chrome.
If you do this, jump ahead to "4." in these instructions.
In Chrome, click the options menu (top right corner), or type ‘chrome://settings’ in the browser.
Select Settings
In settings, click all the way down and click on ‘Advanced’
Look for a section called ‘System’ and disable “Use hardware acceleration when available”
