YouTube and WebM support – fedora
This is from : https://fedoraproject.org/wiki/Flash#YouTube_and_WebM_support
“”" Google has recently open sourced VP8 video format and combined it with Ogg Vorbis audio and a adaptation of the Matroska container to create a new format for free and open video and audio called WebM. YouTube is switching over to using WebM extensively and Fedora has embraced this format as well. Fedora 13 and Fedora 12 has updates to Gstreamer multimedia framework to enable users to play many YouTube videos directly without any use of Flash via browsers such as Epiphany and Midori which use Gstreamer. Fedora 12 users also need the webkitgtk update. Once you have the updates installed, to enable support for it in YouTube, go to http://youtube.com/html5 and click on “Join the HTML5 Beta” link in the bottom of that page. Note that all videos are not available in WebM format yet but this is expected to happen over time. Here is a sample video for testing. Fedora 14 will have more extensive support for WebM by default. “”"
In my view it is fairly a very good news.
