Hi @cyberdave, and thanks for your quick reply.
The app will be accessed from mobile and desktops. It’s a gym app with prerecorded videos. Users should have the option to send the videos to any SmartTV (especially from mobile devices). Examples: Netflix, Youtube.
Somehow, the video player should have the screen share button. I attached a screenshot below (2nd button from the right).
Hope, this time I was more clear as I don’t even know what should I have to look for. Many thanks!
