The latest Chrome for Android beta includes support for Chromecast video streaming. While the desktop version of Chrome supports Chromecast streaming via a plug-in, this is the first time the feature has been baked into the Chrome browser.
The Chrome beta currently only supports YouTube videos viewed in the browser. When a user taps on a YouTube video, a popup appears with options to view the video on the device or on a Chromecast. This makes it easy to send a video to a television without needing to use the YouTube app.
To enable the feature in Chrome beta for Android, type in chrome://flags/#enable-cast into the address bar. You’ll then be able to manually enable the experimental feature. Relaunch the browser to save your changes.
Since the feature is still experimental, expect plenty of bugs and crashes.
