Recently I have started to mess around with the Vorbis audio codec, commonly found within the Ogg media container. Unlike Theora, which I had also experimented with but won’t post the results for fear of a backlash, I must say I am rather impressed with Vorbis.

"...'Ogg' is a wrapper that ties together 'Theora' encoded video and 'Vorbis' encoded sound. Together, Ogg Theora+Vorbis give users a way to see movies on your computer. Ogg Vorbis+Theora are not known to be encumbered by any patents (the only applicable patent on Theora’s predecessor, called 'VP3', was licensed for everyone to use in any way they want).

the and tags along with native support for Theora video and Vorbis audio are currently enabled in the Firefox nightly builds. This will ship in Firefox 3.1 Beta 1 coming later this year. This is not new news but I did want to provide my perspective on why this is important[...] Download a Firefox nightly build here and test it out here or on Wikimedia Commons.

Six years after the project was launched, developers at the Xiph.Org Foundation have released a beta version of the free video codec called Ogg Theora. The source code of the libtheora 1.0 Beta 1 codec library can be downloaded from the developer website.

"After several years of development, the first beta release for Ogg Theora 1.0 - a free video codec - is now available. Now all we have to do is to get some content in the Theora format."

"...Ogg is professional-grade media format. Ogg Vorbis encodes audio and Ogg Theora encodes video. [...] The companies that control the software design it to restrict the users and spy on them. If you choose Ogg Vorbis and Ogg Theora, you can listen to audio and stream video using many different media players, including free software that respects your freedom..."

From today, users will be able to download and install free software to play and encode the new WebM format. WebM is based on the Matroska container format -- replacing Ogg -- and the VP8 video codec which replaces Theora. Crucially, the Vorbis audio codec is part of the new WebM specification.

After a one year beta phase, the Xiph Foundation's free Ogg Theora video codec has been released in its final, "mainline", version 1.0.

"After over a month of public testing, we're pleased to declare our 1.1 rewrite of libtheora stable. This is the reference implementation for the Theora video codec. Source code for libtheora 1.1.0 is available now, and will be incorporated in major Theora-supporting applications soon..." via hacks.mozilla.org
