Theora I Bistream Format Frozen 329

Posted by timothy from the but-it's-a-dynamic-freeze dept.
p80 writes "The Xiph foundation announced today that the 'Theora I bistream format is now frozen,' even though Beta 1 is not out yet and encourage people to try it as 'there's no reason to delay adopting a free alternative any more!' Mplayer and Xine both support Theora. For Windows users, Directshow filters for Ogg Vorbis, Speex, Theora and FLAC are available here. You can get test cases here and transcode Quicktime movies to theora on that page." This freeze, as an anonymous reader puts it, "means that all future versions will support the format as it is now. It will be interesting to see if there is as much uptake for this as there was for the Vorbis sound format."

      The fact that you don't start the battle as a winner is no reason not to fight it.

      Many people create their own content. I consider it much more entertaining than just being a consumer of content, even if my content isn't as flashy as the Matrix or Britney Spears. Because of this, the ability to have free tools to work with is a big deal. I don't care if we never see a movieflix.com movie download site from the MPAA with exclusively Theora content. That isn't the point.

      As long as I have access to tools that aren't encumbered by patents, and I can do whatever the fuck I want with them. As long as Fraunhoffer or MS controls things, it means I can't be certain about what happens to my content tomarrow.

      Oh, and the guys who are interested in video compression have an interesting toy to hack. That's one step geekier than I currently am, but guys decided to make something cool, and they have done it. Isn't that enough? Why does it have to be a battle. Minix wasn't a battle. Fighting wasn't why it was written. But, because it was more open, and assorted Fins could gain access to the source code to see how things worked, they were able to make some sort of Leenoooks clone with help from the tooth fairy. It doesn't matter than minix didn't win!

      Producing a better product isn't good enough. You need a SIGNIFICANTLY better product. For me, ripping even a small ~50 CD collection to ogg isn't worth the marginal benefit, even if it is free. Perhaps if oggs were particularly small, say 10-20% the size of the standard mp3, you would probably see more people flocking to it.

      I realise that free (as in speech) sound and video formats are a good thing but it seems that certain formats, particularly mp3 are now more or less ubiqoutous (sp??).

      I'm not sure that's the case with video. As far as products (not technologies), there's Quicktime/Sorenson and WMV which definitely are not ubiquitous; both are proprietary and somewhat expensive to license. Then there's MPEG-4 which is even more absurd at licensing. Real's format does not really fall into the same category. If anything was "ubiquitous" I would say MPEG-2, but that does not count in the same category either as it does not serve the same purpose as MPEG-4 (MPEG-2 is nearly useless at low bitrates).

      Yes, there are free divx/xvid implementations but those are useless in commercial offerings as they are not properly licensed. So as late as Theora would be getting to the market, IMO, the field is still wide open. Not only has the consumer market not been saturated with any single low bitrate high quality video compression technology, but video "sharing" itself has not reached a maturity level of audio streams when Vorbis first beta was released and standard frozen.

      Actually, all of the file extensions people use are dumb. The file extension only really matters in any deep way to the user; the computer can determine trivially what's in it. The user never cares what container the file uses, and rarely cares what codec it uses. The user cares how the file behaves when played: Does it make noise? Does it look like anything? Does it have text? Does it change over time?

      In order to be sensible, .png, .gif, and .jpg should be .img; .mng and some .mpg and .wmv should be .vid; .wav, .ogg, and .mp3 should be .aud; and most .mpg and .wmv and now some .ogg should be .av; given that the situation is already hopeless, it doesn't really matter that they're using .ogg for both.

    I think the OGG video stuff will have an easier go of it than OGG the music format.

    OGG audio had a few problems - at the start, not as many people knew about it so it was slow to adopt to different players and rippers that people liked to use. The worse problem was that even now it's in almost no hardware, so it made little sense to encode to OGG if you might have wanted to use a portable.

    But with video the whole field is still wide open. Getting a Quicktime or Windows media file to my TV is equally hard, so I might as well store my video in OGG as anything - and I am more likley to be able to build a box I am happy hooking to my TV for video than I would have been trying to construct an audio device I would like. And I have a lot more motivation with every consumer video device being generally locked down in very annoying ways.

    The other thing that will help is that consumer device makers will have little reason not to adopt this video format since it can be another item on a checkbox and is free to implement. Also the processing power is going to be there in whatever device is created - with OGG audio, for a while there was no good example code for playing OGG files on devices without floating point support (as I remember it).

    So, good luck Ogg Theora! I plan to start using it as soon as I can and see how it fares.

Adding another into the mix, while giveing people more choices, probably won't sway one person over. Ogg just didn't do it for me. Theora may not, either.

          You seem to think that Ogg Vorbis and/or Theora must have massive mainstream success (like MP3) or it is worthless. They're not commercial products. As long as people are maintaining the code base and using the software, then it has "worth". I don't think we'll see mainstream success, at least not for a while. And we shouldn't depend on success in that one market, or the lack of it, to measure the general success of Ogg Vorbis or Theora.

          As others have pointed out, Ogg Vorbis is being used by a number of games for the packaged music. I think we'll see the Ogg codecs (Vorbis, Flac, Speex, and Theora) showing up in more embedded packages/devices. Really anywhere there is the need to handle audio and/or video in an application. The application is responsible for playing (and encoding too perhaps) the material. All the user does is install the application and uses it like any other app. It could be VOIP, a training/teaching program, a demo, cutscenes for a game, a TiVO/MythTV/Freevo-like set-top box, etc. You get the idea.

      I used ogg audio to encode my music collection because I didn't have an mp3 encoder and I consider it a lucky break. It was easier to use krecord, audacity and abcde in Debian Woody than it was to get any kind of mp3 encoder. The files turned out to be smaller but of comparable quality to downloaded mp3's. I did it mostly so I would not have to worry about my dying phonograph player and saved out wav files before encoding. abcde worked great for my CDs and the collection, as you know, is much more convenient on a hard drive.

      As for devices, having ogg forced me to get a Zaurus as a portable player. My handspring visor, though still useful, needed upgrading. Zaurus plays both ogg and mp3 from CF or MMC and does so without the annoying DRM problems most players have. So, my $250 investment in Zaurus served more than one function, though it might not be as nice and surely is not as rugged as dedicated players that now cater to ogg. Sharp promisses you can sync Zaurus to outlook as well as read Word Docs.

    They've refered to it as "bistream" in the title of the post on theora.org, and in the body of that post. But elsewhere they call it "bitstream", and that makes more sense to me at least. The term "bistream" is also not in their FAQ.

    Google returns Results 1 - 8 of about 17 for bistream theora [google.com] for me, which is few enough for me to consider it a typo. Is it a typo, or does it mean a dual stream of some kind ?

        Not too bad, thanks for asking. :)

        I wasn't sure if it was, hence asking. It could have been referring to a dual channel stream of some kind, which would be interesting to me, if that was the case. Since no one's said that's the case, I'm going with typo.

    Because it's better, it's free, and it's open.

    It's not ubiquitous, so what? Do you have to commit to using just one format, and no other?

    If you prefer better, free, and open, when you see an ogg in the list of downloads, choose it over the WMP/QuickTime/Real file. If you don't, then pick the one you prefer.

    If you're worried about the web becoming more complex, don't. MS, Apple and Real will just have to work to make things easier than ogg--they have to in order to keep the money flowing in.

    If you're bothered that there's some people out there whose idealism you find disconcerting, just remember, you made a pragmatic choice (you gave up a little money and control in exchange for ease-of-use), these ogg (vorbis, theora, flac, etc) people are working to make it so that you won't have to make that pragmatic choice. They're trying to make the world how you'd really like it to be if you had the choice (unless you are all about acquiring money by controlling access to technology, in which case they are your worst enemy, and you are right to fear them--they will ultimately win).
  • I would like to see Theora (or for that matter Dirac) used inside a matroska container, which to my untrained eye lookes more powerful. It should be possible, but has anyone done it?

    I hadn't a clue the Theora project was as far along as this. The example payed without fault on totem (xine engine) on my Fedora Core 2 installation and looks (ans sounds) really good!

    Keep up the great work!

    Read the FAQ [theora.org]:
    Q: Why the name 'Theora?' A: Like other Xiph.org Foundation codec projects such as Vorbis or Tarkin, Theora is named after a fictional character. Theora Jones was the name of Edison Carter's 'controller' on the television series Max Headroom. She was played by Amanda Pays.

    Now I don't wanna hear another fewl asking about it ;P

  • Tips on Theora usage... (Score:4, Informative)

    Okay, with any luck, everyone will go out, get their video players working with Theora, and start encoding content. So, I think I should throw-out some quick tips before people start complaining and/or getting frustrated...

    First, to get Theora playback for any players on Linux, you need to compile and install the alpha3 snapshot first, and to do that you need the CVS version of all the "vorbis-tools" as they are called. Once you've done that, you just have to re-compile your video playing programs (like MPlayer) with something like "--enable-theora" passed to configure...

    As for encoding, you're probably going to have sync problems... I don't want to waste my time getting in-to details, but suffice it to say you need a version of MPlayer newer than 1.0pre4 (CVS right now), and you need to use the "-vf softdup" option when you are dumping the video to the fifo (from which the Theora encoder is fetching the source video).

    Also, trying to have mplayer dump to video and audio fifos at the same time is guaranteed not to work... You need to either dump the audio to a real file (wastes space), or launch two instances of MPlayer, one dumping audio from the source file, one dumping video from the source file.

    If you don't know what I'm talking about, you haven't started encoding video with Theora, so just keep these tips at the back of your mind, because you'll need them when you do start.

    The only other tip I've got, is to wait until a better encoding program is written. The libraries are fine, but the wimpy example programs leaves a lot to be desired. When other media programs (mplayer, or transcode) start doing encoding via the Theora/Vorbis libs, we'll be a lot better off.

    Just hope that Theora/Vorbis encoding support finds it's way into MPlayer (or transcode I suppose), then you won't need to worry about all of these issues ('softdup' will likely still be needed though).
