I am using background videos here:
On all Browsers, the video start and play without any problems. On Safari 15, the videos start to play and then get stuck. Only after a while they begin to play. It seems to work well with any previous safari version. I did try several stacks for video background play and did try to save videos with e.g. handbrake to enable web playing. To no avail.
Has anybody experienced similar or has a tip of what to do?
