Tested the CastBuddy extension from the Chrome Web Store: nice, but high CPU usage even when no videos
Posted by jpluimers on 2017/04/21
This extension finds videos on the web sites you are browsing and allows you to play them on your Chromecast device.
Works nice if you need it, but uses a lot of CPU (on my Retina MacBook with latest chrome: about 75% of one CPU core) so it drains battery fast.
You can view this high CPU usage in the Chrome Task Manager (which used to be available through chrome://tasks, but this is one of the use full Find Hidden Features On Chrome’s Internal Chrome:// Pages features they removed). Fire up the Chrome Task Manager through the Window menu.
Enable only when you need it. Disable after use in chrome://extensions
When it finds Chromecast comptible videos ( .webm, .mp4, .mkv etc), count of videos is shown over extension’s menubar icon, which you can click to Select a video and extension will send it to your Chromecast device. Once a casting session is established, you can control video playback from Extension’s popup page.
