    Phoronix: Theora 1.1 Thusnelda Is Released

    Theora, the open and royalty-free format that comes from the same folks that work on the Ogg audio formmat, has officially reached version 1.1. Theora 1.1 (codenamed "Thusnelda") is much-improved over version 1.0, which was reached last November. Some of the improvements in the Theora 1.1 encoder include rate-distortion optimization, better motion search, adaptive quantization, a real rate-control module, support for 4:2:2 and 4:4:4 video, and many more changes. A description of the major changes in Theora Thusnelda along with source download links to libtheora 1.1 are available from the Xiph.org mailing list...

      Ogg is the container (which, as a phenomenon, is quite orthogonal from an "audio format"). Theora is a video codec and _Vorbis_ is an audio codec.

        "Ogg Vorbis" - Audio
        "Ogg Theora" - Video
        "Ogg" - Something that contains one or both of the above :P

        So saying "the Ogg audio format" is actually quite OK, it just doesn't mention that the "Ogg audio format" is called "Ogg Vorbis." It's like saying "the Linux kernel audio API". It doesn't mention explicitly that it refers to "ALSA", but is correct. There is a Linux kernel audio API, just as there is an Ogg audio format.

          There's also Ogg FLAC, but I don't think I've come across it in the wild.. FLACs are usually just FLAC and not in an Ogg container.

                Excellent! Free multimedia FTW! Now would be nice to see some unbiased tests comparing h.264, xvid, divx and theora thusnelda.

                BTW for Theora videos the preferred container is actually ogv and ogg is for audio because it's well always been so no point to confuse peole and change it for example to oga. They're both technically same it's just for distinction.

                  Is the container different for Theora and Vorbis? Did you mean the preferred file extension?

                    No you're not understsanding.... there was a typo error as soon as the article was published "formmat"
