URL Cast Receiver

Custom chromecast receiver to display webpages without tab casting

Try it with the sender demo.

Usage

You can use a hosted version now (use 5CB45E5A for your appId), or you can clone / customize this repo and host your own.

URLs are sent to the receiver by sending messages on the urn:x-cast:com.url.cast namespace.

There are two ways to cast a URL to the reciever, each with pros and cons:

Method 1: Loading the URL in an iframe

• Pros: Reciever stays intact after loading page
• Cons: X-Frame-Options: SAMEORIGIN errors

// iframe method
var namespace = 'urn:x-cast:com.url.cast';
var msg = {
    "type": "iframe",
    "url": "http://example.com"
}

session.sendMessage(namespace, msg, onSuccess, onErr);
// reciever is still alive

Method 2: Changing the window location on the chromecast

• Pros: Can load any URL, no iframe origin issues
• Cons: Reciever gets overridden with page load, so you can no longer communicate with it without stopping the cast and restarting.

// iframe method
var namespace = 'urn:x-cast:com.url.cast';
var msg = {
    "type": "loc",
    "url": "http://example.com"
}

session.sendMessage(namespace, msg, onSuccess, onErr);
// receiver is now basically dead to you

Notes

• The chromecast renders webpages at a viewport size of 1280x720 instead of 1080x1920 like you might expect, so be prepared for that.

• The default background color on the chromecast is black, so pages loaded with method 2 (the window location) might have a surprise black background. If you use the iframe method, the receiver sets the body to white.
