For those early adopters of Chrome, via the http://spot.fedorapeople.org/chromium/ repository may find that the necessary codecs are not available for you to enjoy the (eagerly anticipated) HTML5 non-flash version of YouTube…
If you are one of these people, then let me point you to the solution. It will mean that you have to uninstall the chromium-browser package you have installed (remember to export any bookmarks you have!).
Go to the site: http://www.google.com/chrome/eula.html
Click either 32bit or 64bit .rpm . Once the package is installed, Chrome is ran via the google-chrome command, and import your bookmarks. This package seems to have the necessary codecs built in at compilation time, and I am now happily watching my YouTube subscriptions without a trace of Flash. Kudos to the Open Video Alliance, and a big win for open standards.
To watch HTML5 videos on YouTube, go to: http://www.youtube.com/html5 and click “Join the HTML5 beta”.
Note: You obviously won’t get the more frequent “dev” builds from spot.fedorapeople.org, and will instead receive the less regular beta updates from the Google repository (which is added to /etc/yum.repos.d/google-chrome.repo )
