I'm trying to implement an app like Allcast which can use to scan nearby (Apple TV) and pass image,audio,video through apple tv to show them. But i cant figure it out. What protocol AllCast use ? I tried AirPlay but it can't custom UI like Allcast (Scan device, IP, imagepreview),...
Allcast AppleStore: https://itunes.apple.com/us/app/allcast-cast-photos-music/id943763227?mt=8
Finally I found a sdk for these stuffs. ConnectSDK is greate. https://github.com/ConnectSDK
