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]
}
}
