title: Can google chromecast receiver app work without sender app... fed from web server
body: <p>I am currently exploring the possibility of using Chromecast + a custom receiver app instead of a raspberry pi custom code application, or something similar. My goal is to be able to have a Chromecast receiver app pull down various streams/images/text and display them on the TV in some custom layout. If I understand the SDK, the custom receiver html/css/js files would be hosted on my public server, and the chromecast device would pull those down to the device (possibly stored on it?). What I am not quite clear on is if that app can then pull down media files, images, etc and display them, or if the only thing that can be displayed is from a sender app? My concern is we'd like to potentially have 100's of Chromecast devices set up, and using a single server (or possibly a couple) feed the video/image/etc to them individually. In some cases some of the TVs would be used to display the same video/images/text. In other cases they'd be completely separate feeds.</p>
  
  <p>Is it possible to do this, or is this too open ended for what the Chromecast SDK allows for? I am trying to decide if I should look at either custom code on Raspberry Pi with custom code, or if perhaps even something more powerful like the new intel MinnowMax, which I realize is $100, but I need to make sure I can display overlapping graphics, video, text as I want and that I can do so from dozens (or more) devices feeding from a server of mine. One more time, to be clear, I want to store various videos, images, etc on my server, and have them pulled down (and cached) to the local device at a TV to display... so if for example the internet is severed, the device can still display the videos/images/text.</p>
  
  <p>Thanks.</p>
