Xiph Releases Ogg Theora Alpha-3

      Xiph is a group (I believe European or something to get the odd-to-my-USian-ear names) that puts out codecs.

      Ogg is a wrapper format that they put out. It serves much the same purpose as QuickTime, AVI, or ASF does. One wraps it around an encoded stream of audio or data. Currently, Ogg is mostly commonly used to contain audio data encoded with the Vorbis codec, which is notable for tending to sound better than MP3, being patent-free and having a completely free implementation for anyone to use.

      Theora is a video codec also put out by Xiph. It is based on an older, originally proprietary video codec that was donated to the Xiph project. I'm not sure how it measures up to existing video codecs.

      Alpha-3 is, I think, pretty self-explanatory to a developer. It's an alpha release, so the developers are leaving open the possibility that they will make large changes (unlike beta software, where the software should be considered ready, and only lacks feedback from a broad base of people). It is the third alpha release.

      Oh, yes. I love the Far Side strip about Ginger. Remember, though, that saying "awk", "sed", or "grep", which sound quite reasonable to people on Slashdot, sounds absolutely bizarre to most folks.

    I'm happy to announce at long last the release of theora alpha 3. This incorporates all the bitstream changes we wanted to make both for future encoder improvements and to permit lossless transcode of VP3 content. This is an important milestone for us on the road to a stable release.

    As this is an alpha release we are again providing sources only. See the files section of downloads. This version requires libogg 1.1 or later and libvorbis 1.0.1 or later.

    Also new in this release are a set of experimental tools in the win32 directory contributed by Mauricio Piacentini. This includes a transcoding tool for avi-encapsulated vp3 video which also works on linux.

    We hope to not make any further incompatible bitstream changes, but this is still alpha code. Don't use this for content you're not ready to re-encode!

    As for size, it's larger than an I-Pod, and probably too big for most people's shirt pockets, but it's not all that big, and is fine in a beltcase, purse, or in the car, etc. Depends on how you want use it, I suppose. I chose the Neuros over the Karma mostly because of apparent company support: Digital Innovations actually seems to care if it works with Linux or the Mac, while Rio's support is pretty haphazard.

    Samsung's patent

    Each stakeholder has patented a method or slight spin on the basic technique, and so certain claims in each patent could possibly be applied to your arithmetic coder if they wanted to go after you.

    You may need to wait 5-10 years before bundling an implementation in a package with high-visibility that isn't designed for educational or experimental use.

    What you describe is Trademark law, which is probably the sanest branch of north american IP at this point. You cannot trademark common words or phrases (modulo certain exceptions) so an effort is generally made to prevent brand names from becoming same by prosecuting uses of the trademark that don't refer specifically to the actual product.

    Copyrights belong to the author (or sponsor) automatically and can only be given up voluntarily or lost when the rights period expires, which is now some significant time after the author dies.

    Patents are granted on a first come, first served basis to whoever applies for one and provides a monopoly on the implementation of a particular method for a fixed term.

    Neither copyright nor patent rights are contingent on enforcement the way trademarks are. Holders of these two rights can and do choose which infringements to pursue.

    This is the problem with MPEG-4. We can avoid the copyright issue by writing an open source version from scratch, since the standard is at least published. We don't have to call it MPEG-4 so there are no trademark issues, although while the MPEG logo is trademarked in the US, one can refer to the specification because that itself is not a trademark and because there is no attempt at confusion.

    But there is no way around patents because they grant a monopoly on implementation rights. Just because you wrote your own doesn't mean you don't have to buy a license, or that you won't be forced to buy one sometime in the next 20 years. If you live in a jurisdiction that doesn't enforce patents, you're fine for now. If you just want to trade movies underground, you're probably fine because there's safety in numbers. But if you're like me, and want digital media to be as easy and ubiquitous as webpages; something anyone can do, something you don't need permission for, you need a something that's Free as in Freedom and Free as in Beer. Something like Theora.

    that said, I do take exception to one of your statements. If Linux can't do proper mixing, why do I need a better sound card to do it?


    Once again, I'll restate that *it can* do proper mixing. You are dealing with is a limitation of your hardware, not Linux. It just goes with the territory. It's almost like the people that say: "Linux doesn't do 3D because my obscure video chip isn't supported. X sucks!"

    DMIX is a mess. Unfortunately, that's the price you pay. It's not that Linux can't do the mixing that you ask. Maybe, given time, DMIX will improve. It's a relatively new component for ALSA though. You may want to consider paying for 4-Front's drivers that do it if DMIX doesn't float your boat.

    http://opensound.com/

    These drivers support softmixing reasonably well, but aren't free. They are not a proper alternative to hardware mixing, but they will work. They apparently have an ALSA emulation system, but it's just a "play project." I don't know if I would want an ALSA wrapper sitting on top of a sofware mixer though (their Virtual Mixer).

    Your sound chip is essentially like a Winmodem, built specifically for Windows. Even some chips that do hardware mixing on Windows don't mix on Linux because of lack of proper programming documentation. What can the programmers do about that? Again, Linux's multimedia capabilities are not to blame for a driver issue. A good amount of other users don't have the same problem that you do because they have well-supported hardware.

    It's not something that will change unless hardware developers take a different design approach, and a different approach to releasing their programming docs.

    I must tell you that I understand how you feel though. Really - I am sympathetic to the problems you are having. It's a very frustrating situation to have to deal with this sound issue. I've been through it before, as well. This was before the CS46xx drivers were as mature as they are today. I used the 4-Front drivers to hold me over until my hardware got better ALSA support, and it paid off. If the sound issue is giving you that much of a headache, the $20 may be money well spent. That isn't to say that the 4-Front drivers are without problems though, but it is worth testing them before you fork out $20 for a version that doesn't expire after a period of time.
  35. Theora / VP3 probably better than you think by bigberk · · Score: 2, Interesting

    I've got a bit of a surprise for y'all... have you tried the incredible 'Internet TV' (real-time video streaming) available in the Media Library feature in winamp? The quality is really good; the streams are relatively low bitrate, and they stream beautifully. Well, Nullsoft's NSV format is really just MP3 + VP3. So that's what VP3 looks like, and I think it's pretty damn good -- this is by far the best streaming video I have ever experienced. If Theora is an improvement on this, looks like they're heading in the right direction for streaming video.
