Xiph Releases Ogg Theora Alpha-3

ArcRiley writes "For more than a year Xiph hackers have been working on Ogg Theora, an improved version of On2's VP3 video codec. Alpha-3 includes several bitstream changes, VP3 to Theora "upgrade" utilities, and is now supported by Xine, MPlayer, and Real's Helix Player. We're nearing Beta-1 where the format will be frozen, fully documented, and it'll be ready for everyday use."

  1. Another standard that probably won't get embraced? by ChaoticChaos · · Score: 4, Interesting

    The #1 thing about open source compression standards is how unwilling most of the brand name players are to support them.

    I've got a Creative Labs Nomad Jukebox 3 and Ogg Vorbis is still not supported and I'm beginning to wonder if it ever will be.

    If OV supported on the iPod?

    The unwillingness by the major brands to support all standards really leaves the consumer in the bind. I've got OV encoded music tracks and just can't listen to them on my Jukebox 3. :-(

      Xiph is a group (I believe European or something to get the odd-to-my-USian-ear names) that puts out codecs.

      Ogg is a wrapper format that they put out. It serves much the same purpose as QuickTime, AVI, or ASF does. One wraps it around an encoded stream of audio or data. Currently, Ogg is mostly commonly used to contain audio data encoded with the Vorbis codec, which is notable for tending to sound better than MP3, being patent-free and having a completely free implementation for anyone to use.

      Theora is a video codec also put out by Xiph. It is based on an older, originally proprietary video codec that was donated to the Xiph project. I'm not sure how it measures up to existing video codecs.

      Alpha-3 is, I think, pretty self-explanatory to a developer. It's an alpha release, so the developers are leaving open the possibility that they will make large changes (unlike beta software, where the software should be considered ready, and only lacks feedback from a broad base of people). It is the third alpha release.

      Oh, yes. I love the Far Side strip about Ginger. Remember, though, that saying "awk", "sed", or "grep", which sound quite reasonable to people on Slashdot, sounds absolutely bizarre to most folks.

  3. Release Notes by Anonymous Coward · · Score: 5, Informative

    I'm happy to announce at long last the release of theora alpha 3. This incorporates all the bitstream changes we wanted to make both for future encoder improvements and to permit lossless transcode of VP3 content. This is an important milestone for us on the road to a stable release.

    As this is an alpha release we are again providing sources only. See the files section of downloads. This version requires libogg 1.1 or later and libvorbis 1.0.1 or later.

    Also new in this release are a set of experimental tools in the win32 directory contributed by Mauricio Piacentini. This includes a transcoding tool for avi-encapsulated vp3 video which also works on linux.

    We hope to not make any further incompatible bitstream changes, but this is still alpha code. Don't use this for content you're not ready to re-encode!

    Thanks to everyone who contributed!

    Patents. DivX is just a series of alpha-releases for MPEG-4 and is covered by the same set of patents (from dozens of different companies). They're only being nice about DivX until MPEG-4 comes out, then they're going to "crack down".

    Remember when MP3 was gaining popularity, Frauhofer just let everyone do whatever they wanted with players, encoders, etc... but once they realised they had something worth charging for they cracked down and their lawyers started sending everyone ceise and desist orders.

    Ogg Theora is not encumbered by patents. It is, and will always be, royalty-free. To my knowledge it is the first video codec that can be implemented in truly Free Software.

    I'm really interested in Theora, so I've done some looking around trying to get some more information. Theora, from the faq, is a superset of the VP3 codec. I couldn't find much more information on what it is specifically that they improved on.

    The VP3 codec has one major drawback in my opinion. It's designed to keep a constant quality without paying attention to the file size. You can do constant bitrate on it, but you can't use multiple pass encoding with variable bitrates to get that balance of quality while having strict file size control (as with xvid). Is this something that is being added to Theora, does anyone know?

    It's ironic to think of Theora as a "Real-killer", while it does compete on the same field as Real's proprietary video streaming codecs, Real is adopting Theora for the video format in their Helix suite (and throwing money at Xiph to help get Theora out faster).

    I've seen Theora be streamed with Icecast (check out the last Ogg Traffic), I've seen decent quality Theora video at 80kbps (320x240@30 even), and I've seen how well it works in an Ogg container, vs Quicktime/AVI which (unlike Ogg) were not designed for streaming.

    But don't take my word for it, try it out for yourself! That's one of the reasons the Alpha releases are available to the general public. See what it can do, and prehaps, drop us a donation through Paypal or Affero to help the Theora hackers spend more time hacking.

  13. "Beta" definition vs Alpha/1.0 release by ArcRiley · · Score: 4, Informative
    What they're doing now is adding fields to the various headers for flexibility down the road. One example of this is that, unlike VP3, each frame can have more than one quality setting (so that large sections of black/etc won't use the same bandwidth as the hero waving the light sabre).

    These things are not implemented yet, and will probobally not be useable on earlier Beta releases either, but as of Beta-1 the bitstream will not change in future-compatable ways. That is, while some optimisation fields won't be supported yet, no new fields will be added. Future players will always be able to play media encoded by the Beta releases. The same is not true for movies encoded with the Alpha libraries, so Beta-1 is really the first point where it should be used for distributed movies.

    The 1.0 release will include support for atleast decoding these optional fields, it'll likely use them all too for encoding, and should be considerably higher quality than the VP3.2 codec from which it started with. It'll always, however, be able to upgrade VP3.2 media to Theora and, again, always be able to play media encoded with the Beta releases.

    MPlayer and XINE work so well, that even Windows-native formats play back with just a fraction of the CPU load. I have yet to come across a typical, modern audio or video file on the web that doesn't play better on Linux than it does on Windows. MPlayer is just too kickass.

    Audio on Linux is fantastic as well. The ALSA subsystem is professional-grade, allows for plugins and has nearly no latency in routing.

    Multimedia is becoming one of Linux's high points. It's no longer limited like it was a few years ago. The problem is that there are so many patented and closed-source codecs out there that don't have legitimate Linux versions. That's where it gets questionable, when you are required to install a hacked Windows DLL to get a format to play on Linux. Things like Ogg Theora will help to end that ridiculous concept, as Vorbis is slowly doing.

  15. false information? by ArcRiley · · Score: 4, Insightful
    The fact remains that DivX is MPEG-4, because it's patent encumbered it cannot be implemented with Free Software. Many people don't realise this. They think that because there's GPL'ed software available to encode/decode DivX/XviD that the format is free.

    In reality, the royalty requirements of these formats makes GPL'ed software undistributable by anyone but the copyright holder (since it's the copyright holder's responsibility to enforce the copyright they're not going to sue themselves).

    For both commercial and non-commercial uses, royalty-free codecs (such as VP3/Theora) will always top proprietary formats such as DivX.

You cannot trademark common words or phrases (modulo certain exceptions) so an effort is generally made to prevent brand names from becoming same by prosecuting uses of the trademark that don't refer specifically to the actual product.

    Copyrights belong to the author (or sponsor) automatically and can only be given up voluntarily or lost when the rights period expires, which is now some significant time after the author dies.

    Patents are granted on a first come, first served basis to whoever applies for one and provides a monopoly on the implementation of a particular method for a fixed term.

    Neither copyright nor patent rights are contingent on enforcement the way trademarks are. Holders of these two rights can and do choose which infringements to pursue.

    This is the problem with MPEG-4. We can avoid the copyright issue by writing an open source version from scratch, since the standard is at least published. We don't have to call it MPEG-4 so there are no trademark issues, although while the MPEG logo is trademarked in the US, one can refer to the specification because that itself is not a trademark and because there is no attempt at confusion.

    But there is no way around patents because they grant a monopoly on implementation rights. Just because you wrote your own doesn't mean you don't have to buy a license, or that you won't be forced to buy one sometime in the next 20 years.
