Browser Vendors Force W3C To Scrap HTML 5 Codecs 640

snydeq writes "Major browser vendors have been unable to agree on an encoding format they will support in their products, forcing the W3C to drop audio and video codecs from HTML 5, the forthcoming W3C spec that has been viewed as a threat to Flash, Silverlight, and similar technologies. 'After an inordinate amount of discussions on the situation, I have reluctantly come to the conclusion that there is no suitable codec that all vendors are willing to implement and ship,' HTML 5 editor Ian Hickson wrote to the whatwg mailing list. Apple, for its part, won't support Ogg Theora in QuickTime, expressing concerns over patents despite the fact that the codec can be used royalty-free. Opera and Mozilla oppose using H.264 due to licensing and distribution issues. Google has similar reservations, despite already using H.264 and Ogg Theora in Chrome. Microsoft has made no commitment to support <video>."

    Perhaps it is a stupid question but why do the vendors have a say what goes into the spec and what doesn't? Isn't it up to them to choose to implement the spec fully or not? FFS just make it Ogg Vorbis/Theora and if Apple doesn't want to support it then Safari can just not support that part of the spec. It isn't like any of the browser are 100% complient anyway.

          The W3C is irrelevant. The WHATWG didn't start out as part of the W3C, and if the W3C tried to push it around it could just break off again. The contents of the HTML 5 spec are determined solely by Ian Hickson, currently employed by Google. His only oversight is a steering committee.

      The stated reason is that, if vendors will refuse to implement a portion of the spec, that part shouldn't be in the spec. The spec isn't supposed to force vendors to implement something, it's supposed to be a common set of rules that everyone can follow, and mandating Theora is counter to that goal.

        Sure, but there needs to be a way to distinguish between:

        • A) refusing to implement because there are sound engineering reasons not to do so
        • B) refusing to implement because doing so would make it harder for a company to lock people into proprietary formats

        No standards body worthy of the slightest respect should ever concern itself with that second category.

        I am not fond of putting it this way, but I think what really needs to happen is for the average user to grow a pair and realize why Item B is not in their interests and never will be. So long as the masses of users have no understanding of these things, it is always going to be an uphill battle to maintain an Internet that is as free and open as possible.

        Which professional tools are these? Most video editing software I've seen uses either QuickTime or Windows Media for exporting, and both of these have (free) plugins for encoding Theora (and Dirac). You wouldn't want to use Theora as an intermediate format - something like MJPEG or Pixlet with no inter-frame compression is better for that - but exporting from most tools is pretty trivial.

      No, if something being royalty-free were a downside they would not have included a BSD userspace with OS X. While Ogg Theora is royalty free, there are no -known- patent violations. As I recall back when Vorbis was getting off the ground, the implication was made that people with patents wouldn't care unless it got off the ground and then they would start looking for violations.

      Basically, Theora and Vorbis are huge unknowns with potential patent bombs in them, regardless of what the developers and /. thinks. And all it takes is someone with a patent and the muster to enforce it and everyone who implemented them in their browser suddenly has a huge problem.

        The exact same argument can be made for the BSD base Apple uses for OSX. It doesn't matter that BSD went through a long copyright case way back when; both because that case was about copyrights rather than patents, and because unknown patent violations can easily have crept into the code base since then. In fact, I can safely go out on a limb and guarantee that every non-trivial piece of software (including everything Apple has) is violating software patents. Software patents are handed out by the USPTO like Bibles are handed out in prison.

        Apple's argument that they won't use Theora because of potential patent problems rings completely hollow. I'm not going to speculate on their motives, but the one they gave is nonsense.

        Theora is a bit different from Ogg in this respect. Theora is based on VP3, which was both patented and commercially distributed for a number of years. If VP3 had been infringing someone else's patents, then they would likely have sued back when a company was making money from it. The patents that were required to VP3 were released by On2 under a free, irrevocable, license and then (I believe) allowed to lapse.

        Dirac is in a weaker position; it is believed to be patent free, but no one has done a patent search to make sure and it is not based on an existing codec.

        Absolutely - the notion of "submarine patents" rising up, should Theora take off, is not a new idea, and not specific to Apple. By mandating Theora in HTML5, you'd be risking the years of negotiations on the spec on the bet that there are no such patents - a bet I'd be surprised if any good Slashdot reader would take.

        As others have pointed out, HTML has never mandated a specific image format reference in an IMG tag; a type of plugin referenced in OBJECT or EMBED; or the type of resource referenced in an A tag; it's outside it's scope. Let the standard focus on its scope, and let the market hash out the rest - it's not the end of the world to not have a single, mandated codec - in fact, I'd argue that having such a thing would unnecessarily limit our options - Theora is, to be kind, not the most efficient codec on the market; and the situation will likely only get worse. Don't hamstring HTML5 by hitching it to any particular codec.

        Exactly. I hear 'royalty free' and I think of GIF, which was also royalty free... Until it wasn't. Which was an absolutely huge mess.

        Honestly, if I were Apple and the Theora foundation offered a $100-per-million-device license saying basically 'we swear we are the sole authority on Ogg Theora, and you have a license from us to implement it to the spec' I'd be much happier than without it. Because then I'd have a set contract, spelling out the cost, and that if someone then comes along and says 'wait, we own this part of the spec, and you owe us $Xbillion' I could turn around to the Theora foundation and say 'Your breach of contract just cost me $Xbillion, and I expect you to pay that.' Basically, at that point the risk is Theora's, and not Apple's.

        Apple is unwilling to take the risk that there are IP problems with the spec. It would take a lot of costly research and examinations for them to prove there aren't any, and there is no real benefit to them to spend the money and time. Translation: At free, it costs to much.

In other words, "BAWWWWW they din pik my pet codec BAWWWWW i wants every1 usin only my codec BAWWWWW BAWWWWW BAWWWWW!"

    Seriously, folks; QuickTime uses a plug-in architecture for a reason. If Apple were truly concerned about Theora and patents, all they'd need to do is implement it as a plug-in -something they should have absolutely no trouble doing, as it's their own architecture- which could then be trivially removed if the need ever arose.

    How about making the browser use system (DirectShow on Windows, whatever-it's-called on Linux) codecs, so everybody could be using whatever codec they want. Look, a lot of media players on Windows (like WMP and MPC) use DirectShow, so thew users can install additional codecs.

    Why they want to include the codecs in the browsers. This way is worse. If system codecs were used, then the sites could choose whether to use h.264, ogg or some other codec, like XviD.

    Also, this way all of the patent/license/whatever issues for the browser vendors would go away. And if the users are watching video files on their computers they most likely have codecs already installed.

      You're right on a technical level, you really are. But wouldn't that make playing video on the web more like it was in the web 1.0 era? People would have to stay on top of codecs and go surf for these sorts of things. I believe flash won out originally because it was a seamless solution for the end users-- one plugin to rule them all.

      Honestly, the solution you're suggesting is not unlike the way Silverlight/Moonlight handles media-- except that it does have a default/preferred codec.

      Why, you could circumvent the lack of a video tag on IE (or anything else) by using the pluggable codec support in Silverlight 3 to provide a Theora codec. ;) And that won't require any proprietary tools and very little code- just (if the browser is IE, load the following silverlight control, point it to the codec and your theora video)

      We might as well just keep using the object tag to embed media files and let the system figure out what's supposed to run it, if we're going to use system codecs. On Windows, WMP will do it, on Linux, mplayer (or gstreamer if the user is a sadomasochist), and on mac it will be Quicktime. I mean, it's progressive, in an absolutely regressive sort of way.

    What we really need in HTML standarization:

    • Valid XML, all the time. Require that the tags balance, as in XHTML. This will make the document tree well-defined, which, at the moment, it is not. So all software that works on the DOM will behave consistently.
    • Errors put the browser in "dumb rendering" mode. Rather than a "best effort" approach, browsers should, upon detecting a serious error in the input, drop to "dumb mode" - default font, default colors, etc., after displaying an error message. Much of the incompatibility between browsers comes from inconsistent handling of bad HTML. So there should be a penalty, but not a fatal one, for bad code.
    • No more upper code pages. The only valid character sets should be Unicode, or ASCII with HTML escapes. Chars above 127 in ASCII mode are to be rendered as a black dot or square. No more "Latin-1", or the pre-Unicode encodings of Han or Korean. So all pages will render in all browsers, provided only that they have some full Unicode font.
    • Downloadable fonts. Netscape used to have downloadable fonts. The font makers bitched. Bring that feature back, despite the whining. No more having to express fonts as images.
    • WebForms. Get the WebForms proposal back on track. Any needed processing for input should be do-able without Javascript.
    • 2D layout The "div"/"clear" model of layout was a flop. Horrors of Javascript are needed just to make columns balance. Absolute positioning is overused as a workaround for the limits of "div"/"clear". (Text on top of text happens all too often.) Tables were actually a better layout tool, because they're a 2D system. HTML needs a 2D layout model that can't accidentally result in overlaps. There are plenty of those around; most window managers have one. There's been a quiet move back to tables for layout, but people are embarrassed to admit it.
    • Better parallelism. Pages must do their initial render without "document.write()". Forcing sequentiality during initial page load should be considered an error. This will make pages load faster. Some ad code will have to be rewritten.

      You're wrong. The document tree is well-defined in HTML 5. You don't need XML, you just need to follow the HTML spec. Of course, we can't force people to follow the spec, and the Web is currently full of non-conforming pages that include half-assed attempts at using bits and pieces of XHTML mixed with HTML. XHTML doesn't make anything better.

      You're wrong. If your browser does this, users will use some other browser (regardless of whether it conforms to the HTML5 spec or not, because users don't care about that). You're right that broken code is a problem, but HTML5 addresses this by more clearly defining how broken code should be handled, so that all browsers can try to render even bad code in a consistent and compatible way.

      No more upper code pages. The only valid character sets should be Unicode, or ASCII with HTML escapes. Chars above 127 in ASCII mode are to be rendered as a black dot or square. No more "Latin-1", or the pre-Unicode encodings of Han or Korean. So all pages will render in all browsers, provided only that they have some full Unicode font.

      You're wrong. If you make a browser that doesn't support these other character sets, users will choose something else (see above). Of course everybody should be using UTF-8 these days, but we can't force them to.

      Downloadable fonts. Netscape used to have downloadable fonts. The font makers bitched. Bring that feature back, despite the whining. No more having to express fonts as images.

      It's back [alistapart.com], but in CSS, not HTML.

    Audio video codecs are outside the scope of HTML. Whatever it says in the HTML 5 spec about video codecs, that will not magically change the last 20 years of digital audio video away from MPEG to something else.

    The current audio video standard is ISO MPEG-4 (2001) and the codecs are H.264/AAC. Supporting this standard is not an academic issue because the world is full of content as well as hardware and software players and authoring tools that conform to this standard. It's also the video in Flash and in YouTube, which is considered the de facto standard in "Web video". When people talk about Web video they usually mean YouTube or something very like it. They are talking about MPEG-4.

    The MPEG-4 content that you find in the world and on the Web today includes:

    - every song ever offered for sale in or purchased from iTunes Store
    - every song ripped from a CD by iTunes since 2002
    - every video ever made on a cell phone (3GPP is part of MPEG-4) including the iPhone's recent shoot, edit, upload to YouTube feature which is H.264/AAC
    - every video on YouTube is stored as MPEG-4 (no matter what format you originally uploaded)
    - almost all of the video that runs in Adobe Flash, excluding 320x240 movies which may be the old codec
    - all of the consumer video shot on solid state storage, and most of it from a few years before that
    - all Podcast video is H.264 and most Podcast audio is AAC
    - Blu-Ray

    Nobody has explained how all of this content would be transcoded to Ogg or other non-standard format in order to be published on the Web. Where would the computing time come from? How would it be practically done? What are you going to tell someone who wants to upload a video from their camera or phone directly to the Web? That they should transcode it into a non-standard audio video codec first?

    The players are very important also, because they have H.264/AAC decoding HARDWARE, which enables them to work efficiently enough to run on batteries. You can't drop a new software codec into these, you have to drop in a replacement audio video decoder chip. These include:

    - every iPod and all of their competitors, except for the ones that only play MP3 which is part of MPEG-2
    - every PC with a recent NVIDIA GPU can decode H.264/AAC without breaking a sweat or busting its batteries because it happens in the GPU
    - Internet set-top boxes such as AppleTV and Netflix
    - PlayStation3 and other game boxes
    - even the Zune has MPEG-4 hardware in it, although somewhat underutilized from what I hear

    Even software players cannot so easily be modified to support a non-standard codec, because of the scope of the MPEG-4 support. We're talking about every Mac and every PC in the world, because they all have one or both of these:

    - every QuickTime/iTunes since 2002 is MPEG-4
    - every Adobe FlashPlayer version 9 or 10 is MPEG-4

    The reason those 2 match both each other and all the hardware players is because of the benefits of standardization, which took place almost a decade ago for MPEG-4 and goes back further to previous MPEG versions. If you, or Mozilla, or anyone, wants to make an audio video player, they only need to conform to the MPEG-4 standard to enable their player to play all of the content from QuickTime/iTunes and Flash. You can come along in 2009 and decide to get your feet wet in audio video players and simply by following a published ISO specification you can have instant equality with QuickTime and Flash and others. Again, the benefit of standardization.

    A very important consideration that is often completely ignored by Web-centric people as they talk about audio video is the authoring tools! People who make audio and video all day long also want to publish their work on the Web. MPEG-4 is standardized QuickTime, so there is not just 8 years of MPEG-4 authoring tools right now, there is almost 18 years of digital audio video practice realized in MPEG-4. A key feature here is that these tools must not make content that has a "content tax" on it, like

Life is a whim of several billion cells to be you for a while.
