Use YouTube with a Board
Whether it’s a video or live stream, most content hosted on YouTube is embeddable:
https://www.youtube.com/embed/[video-id]
The [video-id] can be found in the YouTube URL In the example below, the video-id is QncFe02SLZo so that the embedded video link becomes:
https://www.youtube.com/embed/QncFe02SLZo
A board with such a link will show a play button that the user can tap to watch a video.
You can modify the URL to autoplay without sound as follows:
https://www.youtube.com/embed/QncFe02SLZo?autoplay=1&mute=1
To loop a single video, add &version=3&playlist=[video-id]&loop=1 to the URL, e.g.
https://www.youtube.com/embed/QncFe02SLZo?autoplay=1&mute=1&version=3playlist=QncFe02SLZo&loop=1
This is useful for a welcome video in your lobby if you wish to replay it.
