YouTube Player doesn't work

Hello everyone,

on my website I have three YouTube videos embedded, which I would also like to make available in the large player. Unfortunately, it is currently not possible to watch the videos in big on the website, but I do not know what the reason is.

Small update: I found out that the videos only don’t play on Safari.

Does anyone have an idea what this could be?

Thanks a lot!
