The issue you are facing:
I have a video in a folder.
I create a share link
I put this link in a service call Mighty Network where they allow for linking a url for a video
When I put the link MightyNetwork says -
Whoops! Must have a video link.
it asks for a standard video url
I don’t undrestand what it wants me to do??
What is a Standard video URL and how can I make nextcloud generate one??
