Support for open ogg format in Mozilla

The organization Xiph.Org and Mozilla have a common direction - to keep the web free and open for anyone, so Chris Blizad’s message that Firefox 3.1 will support Ogg Theora and Vorbis, as well as the html5 element , was not a surprise .

Mozilla is going to add internal ogg support for video and audio in the next release, which will also contain support for the video element tag. (Most likely in 3.1 if no big changes happen.) Code with ogg support was added last night. I think the effect of this change will not happen immediately, but this is a huge step for the emergence of a full-fledged open video standard on the network, which will be used by a couple of hundred million people around the world.

The code accumulated in a separate branch of Mozilla is sent to the main code and is now available by default. You can download the nightly builds and  test . An example of a working site with ogg - Wikimedia video archive
There is still a lot of work ahead. Parts of the format awaiting implementation in functionality, uncorrected bugs. But now you can use the codec on all platforms.

Developers can now say goodbye to proprietary media technologies. For private companies, open standards mean the disappearance of the intermediary and its claims for royalties. And for ordinary users, this means that sending, storing and playing video and audio will become as simple an activity as it is just now with images. 

With the video element and Theora support, exciting development opportunities such as SVG desktops , video commenting and other ways to interact online with video will become real . The adoption of this online revolution by other browsers in the near future will usher in the new age of multimedia. Be a part of it.
