You have the option to include an externally prepared stream in OpenSlides without a connected Jitsi video conference. However, this does not allow interactivity with the delegates or participants.
Enter the URL in the > Settings > General > Live Conference > Livestream URL.
The stream must be compatible with vjs, OpenSlides can by default embed:
- mp4 = 'video/mp4',
- mpd = 'application/dash+xml',
- m3u8 = 'application/x-mpegURL'.
