Chromium is the name given to the open source project and the browser source code released and maintained by the Chromium Project.It is possible to download the source code and build it manually on many platforms. To create Chrome from Chromium, Google takes this source code and adds:
- Integrated Flash Player (proprietary license and code)
- Built-in PDF viewer (proprietary license and code)
- Built-in print preview and print system
- The Google and Google Chrome names (both trademarked)
- An auto-update system called GoogleUpdate (some, such as Ubuntu community builds of chromium, rely on the package management system of the OS as an alternative)
- An opt-in option for users to send Google their usage statistics and crash reports
- RLZ tracking when Chrome is downloaded as part of marketing promotions and distribution partnerships. This transmits information in encoded form to Google, including both when—and from where—Chrome was downloaded. In June 2010, Google confirmed that the RLZ tracking token is not present in versions of Chrome downloaded from the Google website directly, nor in any version of Chromium. The RLZ source code was also made open source at the same time (previously it was proprietary—and although the source is now open the feature was not migrated to Chromium) so that developers can confirm what it is and how it works.
By default, Chromium only supports Vorbis, Theora and WebM codecs for the HTML5 audio and video tags. Google Chrome supports these as well as the patent-encumbered AAC and MP3 codecs. On 11 January 2011, the Chrome Product manager, Mike Jazayeri, announced that Chrome would no longer support the H.264 video format for its HTML5 player.In October 2013 Cisco announced that it was open sourcing its H.264 codecs and will cover all fees required. As of December 2013, Chrome still supports H.264. Linux distributions that distribute Chromium may add support for other codecs to their customized versions of Chromium.
