Firefox, YouTube and WebM

Five important items of note today relating to Mozilla’s support for the VP8 codec:

1. Google will be releasing VP8 under an open source and royalty-free basis. VP8 is a high-quality video codec that Google acquired when they purchased the company On2. The VP8 codec represents a vast improvement in quality-per-bit over Theora and is comparable in quality to H.264.

2. The VP8 codec will be combined with the Vorbis audio codec and a subset of the Matroska container format to build a new standard for Open Video on the web called WebM. You can find out more about the project at its new site: http://www.webmproject.org/.

3. We will include support for WebM in Firefox. You can get super-early WebM builds of Firefox 4 pre-alpha today. WebM will also be included in Google Chrome and Opera.

4. Every video on YouTube will be transcoded into WebM. They have about 1.2 million videos available today and will be working through their back catalog over time. But they have committed to supporting everything.

5. This is something that is supported by many partners, not just Google and others. Content providers like Brightcove have signed up to support WebM as part of a full HTML5 video solution. Hardware companies, encoding providers and other parts of the video stack are all part of the list of companies backing WebM. Even Adobe will be supporting WebM in Flash. Firefox, with its market share and principled leadership and YouTube, with its video reach are the most important partners in this solution, but we are only a small part of the larger ecosystem of video.

We’re extremely excited to see Google joining us to support Open Video. They are making technology available on terms consistent with the Open Web and the W3C Royalty-Free licensing terms. And – most importantly – they are committing to support a full open video stack on the world’s largest video site. This changes the landscape for video and moves the baseline for what other sites have to do to maintain parity and keep up with upcoming advances in video technology, not to mention compatibility with the set of browsers that are growing their userbase and advancing technology on the web.

At Mozilla, we’ve wanted video on the web to move as fast as the rest of the web. That has required a baseline of open technology to build on. Theora was a good start, but VP8 is better. Expect us to start pushing on video innovation with vigor. We’ll innovate like the web has, moving from the edges in, with dozens of small revolutions that add up to something larger than the sum of those parts. VP8 is one of those pieces, HTML5 is another. If you watch this weblog, you can start to see those other pieces starting to emerge as well. The web is creeping into more and more technologies, with Firefox leading the way. We intend to keep leading the web beyond HTML5 to the next place it needs to be.

Today is a day of great change. Tomorrow will be another.

    This is amazing news. So glad to see Firefox get a solid codec upon which to build the future of web video.

    I think by “Matroksa” you mean Matroska. Which is still a strange transcription of the Russian word but that’s how the format is called…

    Yay! I can’t even describe my joy.

    Sadly though, I predict that Redmond and Cupertino will still find excuses for not supporting this.

    1. Tiago Sá

      Lol, that just means their browser will die sooner. I wouldn’t worry too much about them, because, after all, IE6-8 are the plight of today, not IE9. If IE9 doesn’t support HTML5 video, let’s all worry about that when IE6-8 are eradicated.

      May 19th, 2010 at 10:05

      1. Hans Wurest

        According to one of their latest blog posts they are going to support the HTML5 video tag but just with H.264 and MP3 or AAC for audio.

        May 19th, 2010 at 10:34

        1. Wim Leers

          In their defense, they could not have announced support for WebM, since it didn’t exist yet at the time they wrote that blog post…

          May 19th, 2010 at 10:41

          Looks like IE9 will support VP8 codec if installed: http://windowsteamblog.com/windows/b/bloggingwindows/archive/2010/05/19/another-follow-up-on-html5-video-in-ie9.aspx

    I’m so happy Google did it. This is a game changer. It’s going to help alleviate the problems Firefox was faced with in not supporting H.264 for the new HTML5 video tag. YouTube transcoding all videos into the new format is huge as well. Really well done to them. One can quite easily see open video becoming more ubiquitous on the web, I don’t think that’s too outlandish a statement anymore.

    the notorious guys missing are MS for native support in IE9, Apple for Safari desktop and mobile and … Adobe for the video flash player :) We’ll have to deal with browser not supporting video tag for still a long time and sites wont encode videos twice
    Any news from them at the moment ?

    Anyway, we got 5 years before h.264 really becomes a problem, this synchronized move of Mozilla, Google and hardware manufacturers is huge !

    @jpvincent:

    Adobe’s apparently on board. Last bullet point mentioned that they’ll be building WebM support into Flash Player.

    That should help with the IE and Safari problems, at least on the desktop. Safari mobile is still a problem – but it’s not as if it’s a new problem.

    Interesting. Microsoft will support VP8 video “when the user has installed a VP8 codec on Windows”.. I wonder if there is a reason to not install that codec when IE9 is installed? Seems a strange thing to defer to the user when they’re already bundling h264 with newer versions of Windows.

    May 19th, 2010 at 11:00

  20. Alexandre Plennevaux

    in the IE9 catchup announcement, I’m wandering about the main sentence:

    “IE9 will support playback of H.264 video as well as VP8 video when the user has installed a VP8 codec on Windows. ”

    What does that really mean? They won’t ship IE with an open licensed codec? Why is that? What’s the stake? Why the bias?

    Although I’ve heard rumors about this a few months ago, I didn’t believe this would really happen. But it has happened. Best news I’ve heard this year. :)

    Headline should read: Google Saves Firefox Video

    Now we can all admit that Theora wasn’t going anywhere?

    The open question is still whether IE will support this new format…

    May 19th, 2010 at 11:07

    1. gunn

      who cares? if IE or safari cannot/will not support it, they will be left to rot and die and then rot some more. It’s only matter of time before Firefox and Chrome, with help from Opera completely cannibalize the browser market.

      May 19th, 2010 at 12:11

  23. memai

    so, Mozilla has zero energy for Theora now?

    May 19th, 2010 at 11:34

  24. Jan Schejbal

    YES! Great work!

    Given that Chrome is using WebKit and Google probably is willing to share code, I think that Safari can implement it quite quickly and as Apple doesn’t like Flash, I think they will do it.

    The main question here is: WHEN? When will I be able to use a final (or at least RC) version of firefox to watch youtube videos without flash? (i.e. when will both Firefox and Youtube have support for the codec fully implemented?)

    May 19th, 2010 at 11:45

  25. Asa Dotzler

    Brendan, I think the headline should be “Mozilla changed the entire trajectory of this discussion with its insistence on open and unencumbered codecs for the Web”

    That’s not a home run, but an important double or triple during a critical juncture when everyone else was insisting the game was over. Google loaded the bases with WebM and YouTube transcoding. Adobe came in with a nice base hit giving video producers a nice fallback for legacy browsers without extra work. Microsoft has followed with another solid base hit saying they’ll utilize it in IE when available.

    That’s several points from a team effort and sets us up for a win for the Open Web if we can get more toolsmiths and better HTML video APIs over the next couple of years.

    May 19th, 2010 at 11:56

    1. David Smith

      Yay for marketing spin!

      From the actual technical analysis of the code and spec (as opposed to all the marketing hype) it looks like it’s going to take some serious work to bring the codebase and API up to snuff. Have to see if any decent encoders and general tools actually show up in the near future, as that will be the real litmus of its adoption.

      And yes, Asa, if the game was over without this then Brendan’s statements are spot on.

      May 19th, 2010 at 13:59

      1. David Smith

        Actually, I should amend that. There are plenty of crap h.264 encoders around that people use, so I guess a ‘decent’ encoder isn’t a strict requirement. Still need the ecosystem to support widespread use, though.

    unbelievable.

    May 19th, 2010 at 12:24

  29. Kenneth Pardue

    Other than an irrelevant statement on the part of Apple, I think Webm is a given.

    Everyone seems to be settling upon Microsoft pass-the-risk-to-the-user approach of “We’ll play it if the user has it installed” as support for the codec.

    Within weeks, there will be a Quicktime plugin for Webm (according to the project website), which means that Safari will be able to play back webm files via tag if the user has it installed, just as Theora is.

    If it works as support from Microsoft, it should also be considered support from Apple. Still terrified of the potential patent fight and still not too sure of the quality as compared to H.264, but the web ultimately looks to be in a brighter place.

      May 19th, 2010 at 14:36

  32. Chess

    Don’t expect Safari until Apple can fully test what ramifications this will have on its platforms. They have something that works so they are in no hurry to switch it out with something that hasn’t been fully tested and fleshed out. I’d say give them a year, once everyone else irons out whatever kinks it might have.

  35. Jonas

    Sorry, but the IE announcement reads “we’re NOT going to support VP8… but you’ll be able to install it as a 3rd party codec plugin (just like Theora or any other codec)”.

    I don’t understand why people desperately try to read that as they’re going to include VP8. Microsoft will continue to back (the soon irrelevant) H.264 in HTML5.

    Anyway, more power to Firefox!

      Wrong. IE will not use any and all system codecs. The only codec that IE was going to support in the video tag was h.264. Now they say they will support WebM in the video tag as well. Total change of stance.

    Well, expected but nice. Very nice.

    That said, I don’t expect to see MPEG-LA to just sit on this and let it happen. If they are going to toss up a road block, they will. And to be honest, I almost expect it to be quick and hard. The next few months will be interesting for HTML5 again.
    Going forward, I am not sure if this would mean that Firefox will drop Theora in favor of WebM. I would like to see something offical from Xiph on this matter, just to gauge where things go from here for Theora and the sudden appearence of VP8. But for now, will support and improvement continue with Theora in Gecko? That is my question.

    May 19th, 2010 at 13:51

    IIRC Matroska is LGPL license and Mozilla can’t use MPL-incompatible licenses in official binaries. I remembered about Mozilla and libart problem.

    Wow. How Christopher flaps in the breezes. Interesting that WRT the quality of Theora “most people can’t really tell the difference between a video encoded with a decent Theora encoder and a video encoded with H.264″^1 yet as stated above VP8 is comparable to h.264 and “a vast improvement” over Theora.

    Huzzah to Google for VP8 though.

    May 19th, 2010 at 15:26

  42. Brendan Miller

    @Asa Dotzle

    I agree this is a good thing. I don’t mean to rag on Mozilla so much. I do think that not finding some way to include h.264 was a pretty risky decision though, as the quality and popularity of Theora is something outside of Mozilla’s control.

    In the end it looks like it might work out for the best; however, if Google hadn’t swooped in, they would have been in a position where *from the users perspective* IE9 would have had better quality, higher performance built in video than Firefox.

    Keeping in mind that Firefox doesn’t come with Windows, it always has to fight an uphill battle by providing better features/speed/security to justify users going out and downloading it. IE can slip up, and fall behind for years and still maintain market share just because people who don’t know better will always use it, but a small gap on Firefox’s side in feature parity could be deadly.

    May 19th, 2010 at 15:47

  43. dude

    Here’s to hoping that 264 goes down in flames following this. Google is truly the “do no evil” company. I hope they convert all their youtube videos to this format as well :)

  44. Brett Zamir

    “How Christopher flaps in the breezes”….

    Something can be a “vast improvement” over something which is not noticeable to most people.

    I’m one of the people who found Theora just fine, though I’m willing to admit it could be improved vastly–kind of like HDTV was over regular TV. Or maybe more analogously, an audio amplifier which went from supporting 19,000 Mhz frequencies to 25,000. Most won’t notice the difference, but it settles the concerns, even if they were considered of less importance by open video advocates.

    I admire the people sticking up for principle here because if it had been a choice between HDTV controlled by a monopoly and regular TV under competition, I’d choose the latter. And having open video on the web where you get a greater choice of what to watch is even more important than for television.

    So hats off to those bumping up the technical quality beyond an already quite workable format, and hats off to those ensuring it was going to be an open format.

    Amazing how much struggle there has to be for something so obviously necessary as this…

    May 19th, 2010 at 19:22

    1. David Oliver

      Spot on Brett.

      I see this as first and foremost a big step to securing an open base for video on the web. Quality is secondary to freedom.

      Hopefully with Google’s weight behind it, it will be defended from patent litigation and we’ll be able to build on open and available-to-anyone video from here. But I’m not sure how it works – would Google be the target or would MPEG-LA pick its targets from users of VP8 who publish content using the codec?

      May 20th, 2010 at 00:45

    2. voracity

      Spot on, Brett.

      An immense amount of thanks to Mozilla for having the courage to act as the web’s conscience. And an equally immense amount of thanks to Google for doing something that most big companies would never have the principles or conviction to do.

      There will be no Firefox 3.7 – the next release has been renamed Firefox 4.

  48. Stifu

    Very good news.

    I’m a long-time Firefox user, but I’m abused by the fact Mozilla won’t admit problems until they’re solved. It was the same with memory issues with Firefox 1.5 and 2.0, for example: memory leak complaints were all denied until Firefox 3.0 fixed most of them. It starts like “There are no problems, it’s all in your head”, then “Hey, we fixed the bugs!!!”. Haha… It’s basically the same regarding Theora here: “It wasn’t so great after all”. That’s what it sounds like to me, at least.
    Still, I can understand. It’s never good publicity to disparage your own product(s). I just thought this was kind of funny. But hey, it’s the same with Microsoft and IE, now they’re like “Hey, we love web standards!”, while you didn’t see them say “Fuck web standards, we ARE the web!” before (at least not that openly).

    1. Ken Saunders

      Stifu, your last paragraph was hilarious. Truthful too.

      May 20th, 2010 at 23:32

  49. Ken Saunders

    I was/am disappointed by the fact there was never a strong and cohesive Mozillian majority or force behind really promoting the use of Theora.

    You’d be hard pressed to find anything negative that I’ve ever publicly posted about Mozilla, and I’m not trying to call out anyone in particular (that would be uncool), I’m talking about Mozillians collectively and this is a Mozillian site so I feel comfortable with speaking my mind about it without fears of being outed by anyone.

    I learned about Theora through Mozilla (Asa and Air Mozilla to be precise) when support for it in Fx was on the way. I do my best to support all that Mozilla does and so I did for their efforts to promote the use and adoption of the Theora format and open video in general. But time after time, then and even now, I come across sites and blogs where people still choose to post Flash videos and embed from sites that made the clear and obvious choice, and followed Google’s lead not to support Theora especially when converting to Theora is a piece of cake, and there are (albeit poor) open video hosting sites.
    I just never understood that. It has been a bit deflating too to be honest.

    Oddly enough, some of the videos were intended for Firefox users, and some of the content about those videos was about HTML5 and open technologies. It’s mind boggling.
    Mozillians who stuck to using and posted Theora videos should have been dogging other Mozillians about them using Flash and sites and services that don’t support Theora and smacked them in the head and said “What are you thinking?!”

    I’m happy that there may now be a good and agreeable open video format solution. That’s awesome, it’s great for everyone,.
    I just hope that something like what I experienced doesn’t happen again and everyone can get on the same page.
    Mozilla can’t expect us supporters/advocates/volunteers to get behind and believe in something if it’s something that official Mozillians won’t get behind themselves.

    Perhaps Theora would have been more successful and improved had the entire Mozilla ecosystem been behind it. Saying that we’re sticking with it, and actually promoting it and educating people about it are different.

    I feel as if I wasted my time and was fighting a losing battle and/or one that couldn’t be won.

      Keeping it:

      “We believe that it is in the public interest for HTML5 video to be backed by multiple, open and royalty-free codecs available in a way that is consistent with the W3C license standards. We would absolutely consider H.264 if MPEG LA would make it available under open web terms as defined by the W3C standards. We stand by our position on Theora.” (Mozilla press statement)

    YouTube’s WebM player is still buggy and switching from 360p quality to 720p sometimes doesn’t resume playback and I have to refresh the page several times. This has to be fixed. Works fine in Google Chrome.
    Don’t know if this is a bug with the video support in Firefox or if Google needs to add code that deals with Firefox differently. Best case would be if the same code worked the same in all browsers. but even with HTML5 this isn’t the case.

    When will the web be truly unified and universal?

    WebM is a giant step *backwards*. Vorbis is a lossy audio format, so guess what, folks? All of you who worked your ass off to set the mics, amps, monitors, cables, boards, software and hardware just right to achieve the best *lossless* sound for your YouTube video, are about to have your work transcoded to this crappy “WebM” thing. I offer my most sincere condolences.

      You have no idea how lossy works do you.

      Yes, a little data is lost. But what is lost is generally beyond human perception.

      And might I add, the other competing formats, H.264 and ogg are also lossy formats.
      Also, I might add that only on still images have a noticeable data loss. But as I said, it is not noticeable on ogg, webm, and h.264.

    If I remove “flash player in Firefox our chrome, i Can’t play video on ‘Youtube.

    I’ve changed my user agent in Safari browser to Ipad ios5 to force use html5 videos, it don’t support it. why can ipad play youtube videos without Flash player, but safari on windows need Flash Player. I DON’T UNDERSTAND THIS apple!

    Hi, Is there any good Firefox add-on which automatically switches to HTML5 on YouTube and sites alike, to avoid the manual steps to join the HTML5 “try something different” found on YouTube?

      Not to my knowledge.
