Screen mirroring from macbook to apple TV 4k not showing video

When screen mirroring from my 2015 macbook pro to my apple TV 4k, I can get sound from videos but not the actual video, just a black/blank screen. When screen mirroring the same video from my iphone 13 I am able to get sound and picture just fine. When screen mirroring from youtube.com on my macbook it works fine, but from other websites like CBS or ballysports etc., I can't get videos to play.

I have tried different browsers and websites. My macbook is updated with the latest macOS.
