Hi Hyun,
thanks for your quick reply!

Well, your assumption 1 is correct – I use the block editor.
Assumption 2 is half-correct… I see the controls for that block, but cannot find any setting to show video player controls in frontend.

So when I view my page in frontend (as a usual visitor would do), there is the video and it’s playing correctly. However, there are no controls like playtime, mute/unmute, pause/play etc…

That’s what I’m looking for, as without controls the video behaves strange. If you click on it, it pauses. If you click again, it don’t continue to play 🙁 I would like to enable the reader to control the video and e.g. play from begining if he wishes to.

I’m using a webm video… Could this cause this behavior.
