When using Evercast for the first time, you will be prompted to "Allow" your webcam and microphone. If you accidentally clicked "Block," you will have to re-allow the devices. This guide will walk you through that process. Click the three vertical dots in the top right corner of your Chrome browser.
This will open a small menu. Click the "Settings" option and the Chrome Settings page will open up in a new tab.
On the Chrome Settings page, scroll down until you see "Advanced." Click that to display additional settings. Click "Site Settings" then click "Privacy and security."
Inside of the Site Settings window, you will see "Camera" and "Microphone." Click the device you want to unblock.
You will see https://v2.evercast.us:443 under the "Block" section. To unblock, simply click the Trash Bin icon.
Now that your device(s) are unblocked, you will need to Allow the device(s) in Evercast. Join an Evercast room and before you go live, you will see a popup asking you to Allow/Block your device(s). Click Allow for both your webcam and microphone. Once you see yourself, click "Go Live."
Go to System Preferences, then Security & Privacy. Click the Privacy tab and on the left side of the window, find Camera and Microphone. Make sure Google Chrome is checked in both tabs. Note: If Camera/Microphone aren't listed, skip this step. Now, refresh the Evercast room in Chrome and see if the camera is available. If this didn't work, continue:
Restart the mac computer, and join back into the room to see if the reboot fixed it.
In the Windows search box, type 'Camera privacy settings'. Scroll down and make sure 'Desktop web app viewer' is On. Refresh the Evercast room and it should fix the issue. If it didn't work, try restarting the computer.
