Hello,
I am trying to make an app that I can get live video off my laptop (Like games) and for the video to display on my phone using bluetooth and or wifi (what ever way is easiest) . Kind of like using my phone as a monitor. I am new to coding but I understand some of the basics but I am having trouble. Is this even possible and if so, How?
Sorry, it might not be the best description.
Many Thanks 
I have the same problem
You can use this chrome browser plugin on your computer. It allows you to stream your screen to the internet. In your app you can use WebViewer to view streaming video.
Welcome Mariam.
Same problem? Displaying videos depends on where they are stored. The tool in App Inventor is theVideoPlayer . Have you tried it?
Perhaps http://appinventor.mit.edu/explore/ai2/videowall
or one of these other links https://community.appinventor.mit.edu/search?q=videoplayer ??
What have you tried?
