Theora 1.0 Released, Supported By Firefox

YA_Python_dev writes "The Xiph.Org Foundation announced Monday the release of Theora 1.0. Theora is a free/open source video codec with a small CPU footprint that offers easy portability and requires no patent royalties. Upcoming versions of Firefox and Opera will play natively Ogg/Theora videos with the new HTML5 element <video src="file.ogv"></video>, and ffmpeg2theora offers an easy way to create content. Theora developers are already working on a 1.1 encoder that offers better quality/bitrate ratio, while producing streams backward-compatible with the current decoder." Adds reader logfish: "Since its bit-stream freeze in June of 2004 there have been numerous speed-ups and bug-fixes. Although Nokia claimed it to be proprietary almost a year ago, nothing has been proven. So now it's time to help it take over the internet, and finally push for video sites filled with Theora encoded vlogs, blurts and idle nonsense."

    I really want to like Theora, but it's really, really hard to get around the quality issues. VP3, which Theora is based on, just isn't competitive these days. It was subpar back in 2001 when it was donated to Xiph, and the contrast has only gotten worse over time. H.264, VC-1/WMV9, MPEG-4 ASP, even Adobe Flash 8 (which added VP6) are clearly capable of outperforming it.

    If nothing else, free is good (both in terms of speech and beer) and a royalty free standard for video would be great, but it's too hard to ignore just how inferior this standard is. I'm a pragmatic person, I can't think of any reason why I'd want to use this over a better codec; free isn't all that enticing if the video quality sucks.

      With the billions of crappy flv video being used all over the web, are you claiming that cutting edge video technology is the key for broad acceptance ??

      But, those are issues that can be addressed, and with more attention like this it will get more help from "joe the programmer"

      Can it though? Certainly part of the issue is definitely the encoder, but you're still constrained by the inherent limitations of the codec (and more to the point, the decoder). Theora can't be overhauled without breaking the decoder, and even if it was overhauled as Theora 2.0, it couldn't implement any of a multitude of patented video compression technologies already used in MPEG or other standards. And unless someone wants to hire a team of engineers for Xiph, the odds of someone inventing a revolutionary, non-patent-infrining video codec on their own is pretty slim.

      From what I've seen with the work on 1.1, improving the encoder just isn't enough to nullify the deficiencies in the codec itself. It's like trying to improve Mac OS Classic when really you need to make a clean break and invent Mac OS X.

      Don't forget, lots of nightmarish IE specific stuff also "Just Works" for "The Majority", And ask any 64bit linux user exactly how much they love adobe for their support. (I think they have it now, after something like 4 years of waiting or running in emulation, or running a 32bit OS on their 64bit machines)

      The magical wonderland I think of is one where anyone on any system can easily watch video online, not just the majority.

      if anyone goes through with this, choose a video which contains:
      - noise
      - fire
      - rain or snow
      - smoke

      These are the frames which have the highest amount of entropy and are easiest to visually illustrate the quality of a coder.

  2. So you prefer Flash installed on every browser? by Lino+Mastrodomenico · · Score: 4, Insightful

    Sounds like feature creep and bloat to me.

    Why? Ins't going to affect you if you don't visit pages with videos and, unlike Flash there's a browser preference to start all videos in paused state. The Theora binary library is only 250 kB on AMD64, even smaller on x86. The Flash plugin, is much, much bigger.

    Video on the internet (think youtube, movie trailers, pr0n, etc.) isn't going away any time soon.

    The current state of the art is to have a proprietary Flash plugin installed in almost every browser. Switching to native support for an open format directly in the browsers seems like an improvement to me. In the good ol' days, people considered image support in browsers as bloat too..

    And Firefox isn't alone here: Opera and Safari will support it too (altough Safari will not support Theora out-of-the-box).

    Just like MKV hardly anything will play it, but unlike MKV it doesn't actually add anything useful.

    You've obviously never negotiated costs with MPEG-LA, or you wouldn't say that.

    Thats parents point. H264 etc are patent encumbered so Theora does add something very dam useful to the community just like MKV does. MPEG-LA is the group that runs the patent pool on mpeg/h264 etc while the OP was suggesting that Theora is without merit.

    If we want h264/mpeg4 support in FF you going need about $3M+ donated per year for the license fees.

    If you have ever needed to care about the licensing of things like codecs you would know the value of Theora and Dirac.

    As Wikipedia would say: "Citation needed".

    Care to show an example of *any* MPEG-2 codec out performing the current Theora encoder on a typical web-video 500kbit/sec stream? Forget the new enhanced theora encoder, MPEG-2 can't even match the old crap. Plus mpeg-2 is patented to hell and back, you even have to pay for mpeg-2 decoding in Windows to play DVDs!

    Can you cite a *single* example showing Vorbis to be glaringly inferior to AAC? At best the listening tests show AAC to edge out Vorbis only for speech samples at the lowest bitrates (where Xiph has Speex, which blows AAC away for those applications). And no multi-channel? wtf. Vorbis supports 255 channels.

    I shouldn't expect better from slashdot, but could you at least find lies that are a bit less obvious.

    Ogg high overhead? Okay, Ogg/Vorbis+Theora is something like 1% overhead vs a typical of 0.9% overhead for a movie in AVI. You win there. Then again, OGG provides frequent checksums so that a damaged OGG/Vorbis file will *never* break your speakers and damage your hearing. People who have had the misfortune of hitting a corrupted MP3 in their iPod playlist should be able to appreciate the advantage of this approach. What you consider a fault I consider a feature. Egads, room for design differences exists! who would have thought?

    Yes there are examples. Just ask the mplayer developers. Even in the EU its not as clear cut with software patents as /. will have you believe. Our lawyers said that your fine if you aren't selling it, probably, but don't push it with commercial (for profit) products and services. The idea of using codecs on the basis that "they won't do anything" is about as smart as claiming RIAA won't do anything for downloading music. Quite a few said that back in the napster days. You remember how that went.
