In the agenda or on the home page you can embed videos via html (Quelltext) with the following line:
<video src="https://www.learningcontainer.com/wp-content/uploads/2020/05/sample-mp4-file.mp4" controls="controls"></video>
This only works when the link ends with a video format ending, e.g. ".mp4" in this example.
Youtube videos do not work directly because we cannot offer iframe embedding for security reasons.
