Does anyone have idea about Microsoft stream? Can we use RestApi in Stream and Display all the videos in On-premise?
As of today, there is provision for using Stream videos only in SharePoint Online. Link - Microsoft Stream webpart for SharePoint Online
But, we can expect Microsoft to release their administrative controls soon in Steam, so that we can leverage REST API and use the videos in SharePoint onpremises. The transition from Office 365 videos entirely into MS Stream is already on its way.
