Chromecast ist ein günstiger HDMI-Stick von Google, um Inhalte von Androidgeräten auf den TV zu übertragen. Darüberhinaus können auch Inhalte vom Laptop oder Desktop-PC aus dem Chromebrowser gestreamt werden. Wirklich gut funktioniert Letzteres jedoch nur mit YouTube. Bei anderen Seiten, insbesondere Videoinhalten, fällt die Bildübertragungsrate auf wenige Bilder pro Sekunde herab.
Note: Personally, I haven’t experience any non-fluent streaming with the Chromecast since an update somewhen in late 2014, but according to the comments the problem is still persisting and the solution presented here still works.
This is because the “Google Cast” named extension for the Chrome browser only in the case of YouTube transmits the actual video URL to the Chromecast dongle. Otherwise, it mirrors the contents of a browser tab – which naturally means a lot more data that must be transmitted.
Luckily, there is a way to bring videos smoothly to your TV, even if these videos are from other vendors than YouTube, such as Vimeo. The bookmarklet Vidcast also fishes the video URL and transmits only that URL to the Chromecast. Unfortunately, even this works only with certain videos because Chromecast supports only a limited selection of video formats.
For the mentioned bookmarklet, the “Google Cast” extension must be installed nevertheless. To install the bookmarkslet, pull the blue “Vidcast” lettering via drag and drop into your bookmarks bar. Later, when viewing a page with an embedded video, just click on that new bookmark. If the page and/or the video format are supported, the Chromecast transmission can start.
Converting the bookmarklet into an extension
If you have the bookmarks bar hidden usually in your Chrome browser, it might make sense to convert the bookmarklet into a Chrome extension. This saves you from the necessity of enabling the bookmark bar temporarily all the time.
First navigating over to http://sandbox.self.li/bookmarklet-to-extension/. Now drag&drop the Vidcast-bookmarklet once from your bookmarks bar into the large text field with the appropriate label. Enter
Vidcast into the name-field.
A click on »Generate extension« will generate a ZIP file and offer it you for download. Extract the files from this archive to an arbitrary, yet permanent location, i.e. not to
/tmp on a Unix-based system.
Now open the preferences of your Chrome browser. Within the Extensions section, first activate the development mode and than click on Load extracted extension. Choose the location that you extracted the contents of the ZIP file to.
That’s it. The VidCast-functionality is now always available with a single click on the red, black circle, without the necessity of having the bookmarks bar enabled. I’ve put the extension into a single download file, in case one of the links is dead sometime.
