Theora 1.0 Released, Supported By Firefox 310

Posted by timothy from the funny-name-and-all dept.
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."

              Many posters here are confusing two things here: codecs and containers. Theora is the videocodec, OGG the container (which has the extension .ogv). OGG (as per .ogv) is also the standard container for Theora, which Firefox supports. But, MKV being really a superior container on pretty much all fronts, could contain Theora equally well as any containerformat (actually, better IMHO). Just making sure everyone is talking about the same thing.

            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.

    • ogv (aka ogg) and mkv (can be named mka for audio-only too) are containers. Theora is a codec. Like H.264 aka MPEG 4 AVC. Except that H.264 is an actual standard which compresses much better. (Theora is more "last generation".)
      Unfortunately, H.264 ist patented, so for some applications it's out of question.

      Oh, and in terms of containers, mkv kicks the shit out of ogg. ;)

    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.

IE will support WMV and Safari will support Quicktime, and both will support theora through 3rd party plugins which will only be installed by people who know well enough to use firefox anyways.

If Theora can catch up to MPEG-4 ASP codecs and perhaps even close in on H264, it would make for an excellent patentfree codec.

        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.

          The fact that the quality improvements for theora 1.1 put it on par with a base mpeg4 implementation while not on par with the most recent h264 encoders is not really relevant in the larger sense.

          Once a free codec becomes widely adopted the chance of some proprietary codec coming along afterwards is near zero. Its just like today we can't imagine someone coming out with a proprietary image format and expecting people to adopt it.

          Its relatively easy to add in support for Dirac or some future free codec once there is support for a free codec ecosystem. No one will pay h264 licensing costs when quality free alternatives are vibrant. The entrenched proprietary systems are being pushed aside for free alternatives. This 1.0 release is a step towards that direction, not as big of a step once firefox 3.1 ships but an important step ;)

      Think of Theora as a successor to MPEG-1 on the web. It works everywhere, is easy to support, and doesn't need much CPU to play back (so you can use it for mobile sites), and the quality is 'good enough' but not great. At the other end there's Dirac (which also went 1.0 recently), which provides amazing quality but at the cost of much higher CPU loads. If you're streaming films or HDTV episodes, you'd want to consider something like Dirac. If you're just showing little clips and you want them to just work, you'd use Theora (well, at the moment you'd use MPEG-1, but hopefully in the future you can use Theora).
    • Theora is not VP3. The format is *much* more flexible and the 1.0 decoder supports all of it. Which means that in the next years we will see many improvements in the quality, with the same bitrate and 100 backward binary compatibility, just enhancing the encoders.

      Theora quality is good enough. You may be able to see a difference under a microscope but not to the human eye.

      To get a good quality video, from A to Z must be quality, not just one step.

      Many convert a MPEG video into Theora and say Theora video is not good quality. MPEG means video is already compressed and data is dropped as part of the encoding process. You don't take a such a video and convert the format to Theora and drop data again as part of the Theora encoding process. Its of course not good quality then, because data is dropped twice.

      To get real quality video in Theora, you should get a raw video and convert to Theora. I have converted a raw video footage shot by a RED camera (http://www.red.com/) into Theora, I don't see any quality issue. Its crisp clear.

      In digital camcoders this is what is done inside, ie. it first shot in raw and then convert to MPEG. I have not come across a video camera that convert to Theora natively inside the camera. If it does, there should not be any quality difference compared to MPEG.

      • Starting from a decent bitrate MPEG-2 video (say, 2 GB/hour), there should be no problem creating good Theora encodes from them despite already being lossy. And if Theora can't do that without looking like crap, then it fails next to codecs like H.264 that can.

      They're aimed at different markets. Dirac is a very high-quality CODEC, but it is incredibly CPU intensive. Remember what MPEG-4 was like when it was introduced? A couple of days to encode a film, and you could only just decode it in realtime on a fast computer? Dirac is like that. It will be a few years before you start getting Dirac support in something like an iPhone. If you want to stream HD content, Dirac is a good choice.

      In contrast, Theora is very cheap in terms of CPU power. You can run it on very low-power devices. This makes it a good choice for Internet video, where the viewer might be using a massive desktop computer, a mobile phone, or anything in between. You wouldn't want to use Dirac here, because even fast laptops would struggle not to drop frames, and handhelds would just fail.

      That said, my mobile phone now has about as much CPU power as the PC I had when I first got an MPEG-4 video, so eventually it will be feasible to run Dirac in low-power devices (sooner if they have dedicated ICs), but in the short term it's not ideal.

    I admit I don't know what the situation with Theora's licensing history is but this comment strikes me as rather worrying. We're being told to use it because no one's proven it's not likely to end you up with licensing troubles later on. Personally I'd rather before something "takes over the internet" that the burden of proof was on it to demonstrate that it is completely open. This should be as easy as showing use of a relevant open license no?

    From what I can see it's under a BSD license and so should really be open. Is this the case? The way the article summary is written just really doesn't instil confidence in their intentions.

    Giving this codec the benefit of the doubt I think the summary is just a case of carried away fanboyism having an adverse effect towards the neutral observers view of the situation much as seeing a forum war between a PS3 and a 360 fanboy might put someone off the idea of online console gaming.

      The video encoding field is crowded with patents, so it's probably impossible to do something like Theora without needing a patent license. But Theora is based on some patented technology (VP3) whose patents have been donated for free use, irrevocably forever. And Theora is free, open source software with a BSD license. If you use the Ogg container format, Theora video, and Vorbis audio, you have a completely free media format.

    gst-launch-0.10 filesrc location="$1" ! decodebin name=decoder { oggmux name=muxer ! filesink location="$2" } { decoder. ! ffmpegcolorspace ! theoraenc ! queue ! muxer. } { decoder. ! queue ! audioconvert ! queue ! muxer. }

    Add the Fluendo codecs, and you have a properly patent-licensed, legal way to transcode most popular media to no-patent-royalties media types.

  • Now, if there are decent (freeware?) applications that can encode the format that would be great. You have to pay for Flash video encoding, and even if you can pay, asking about a Flash video encoder [swishzone.com] for Linux.. who cares about Linux. If you use MPEG4, some players are picky on the type of MPEG4 codecs you used to encode a video when you play it back. . Microsoft video format is just a pain in the backside.

    A video format without the security problems of Flash, bring it on.

      What's wrong with ffmpeg and ffserver ? I encode swf video on the fly from a mjpeg stream originating from an IP camera. It's currently quite choppy as I can't get much more than 6 fps to stream consistently over an ADSL connection without using all the available upstream bandwidth. That is not an issue for a local source file.

      So, it's not really like YouTube. Who's going to self-host their own videos? That is the whole point of YouTube!

    and ffmpeg2theora offers an easy way to create content.

    Only for certain definitions of easy. Let me know when you have a point and click version that my non technical friends can use.

      Easy. On Windows, create a shortcut to it on the Desktop, or just have the executable on the Desktop. User can just drag a video file onto it, a Window pops up telling them the time left, and when it's done an Ogg Theora video file is dropped in the same directory as the original video, and with the same name (but with .ogv). No need to break out the command line.
