Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

YouTubeなんかの動画を再生するには当然便利なんだけど、ローカルの動画とかを再生しようとなると Google Chrome（Chromium）で file:///にアクセスして Google Chromeの画面をキャスト…みたいなことになるのでプレイリストが使えなくて面倒くさい。普段は mpvを使っているので Chromecast 用のプラグインでも追加されてないかな〜と思ったけど今のところは非対応っぽい。
