On a daily basis, Safari will randomly stop displaying any video content from any website. Only a black screen will be displayed in the video area - often the playback bar will still progress, but no video will play and sometimes audio will play, but not always. This will most often happen on Youtube where I am given an error message when the video does not load or stops playing. In this state, if a video is already playing and I navigate to another tab and come back, the video will stop playing. The problem usually arises when I click on a link/thumbnail to play a new video.
Quitting and restarting Safari resolves the issue for a time, but it inevitably comes back. Sometimes within minutes, often within hours, always daily. When in this "broken" state, other web browsers (Brave and Firefox) continue to function and play video - the same exact videos with the exact same link copy and pasted. When broken, I've also attempted to open an h264 video directly in Safari, and the same issue happens - black/no video but audio plays. I can't pinpoint exactly when this started, but it was within the 6 months.
I do not have any extensions or ad blockers installed on Safari. Using a Private window does not help. I have tried clearing cache and history etc etc in this state, but it does not help. Activity Monitor does not show any abnormal CPU or Memory load.
The issue is only in Safari.
