CastDog is a chromeCast watchdog. It watches the configured chromecasts for changes in the running application. When found that the backdrop is running, it casts the predefined application.

This keeps a standard application running, but also allows you to cast your own content. When you stop casting, CastDog takes over and reinitializes the default application.

to start create a config.json file like this:

{
    "chromecast name": {
        "url":"http://www.example.com/",
        "rotation": 0,
        "zoom": 1,
        "aspect": "native",
        "overscan": [0,0,0,0]
    }
}
