How do you build a master application to play video in local network?


I wanted to create an app where multiple devices are connected to one wifi router where I can use my app as a master application and select the video/image which I want to play, select the tab that I want the video/image to be played on, and send the video/image file through wifi (without internet). I'd love to hear your tips / best methods and ways to make this possible.

Thanks! (:

From what I know, you cannot push a video stream to other devices in the way you describe. Those devices will need to pull the stream from the server.
