The Android app I'm currently working on can stream to Chromecast and Roku. A feature that needs to be implemented in the near future is the ability to stream to the Apple TV. I just came by this API which allows me to stream files stored on my phone to the Apple TV:
I was wondering if there are any other similar API's out there? It'd be nice to have some choice to see what I need, before I start integrating it into my app.
