Theora Development Continues Apace, VP8 Now Open Source
SergeyKurdakov writes "Monty 'xiphmont' Montgomery of the Xiph Foundation says the latest action-packed, graph- and demo-clip-stuffed Theora project update page (demo 9) is now up for all and sundry! Catch up on what's gone into the new Theora encoder Ptalarbvorm over the last few months. It also instructs how to pronounce 'Ptalarbvorm.' Ptalarbvorm is not a finished release encoder yet, though I've personally been using it in production for a few months. Pace on improvements hasn't slowed down — the subjective psychovisual work being done by Tim Terriberry and Greg Maxwell has at least doubled-again on the improvements made by Thusnelda, and they're not anywhere near done yet. As a bonus Monty gathered all Xiph demo pages in one place."
Also on the video codec front, and also with a Xiph connection, atamido writes "Google has released On2's VP8 video codec to the world, royalty-free. It is packaging it with Vorbis audio, in a subset of the Matroska container, and calling it WebM. It's not branded as an exclusively Google project — Mozilla and Opera are also contributors. Builds of your favorite browsers with full support are available."
An anonymous reader points out this technical analysis of VP8.
Analysis can be found here. Comparison pictures to other codecs are included.
So if you want to see who is watching a given YouTube (or porn site) video, just watch it yourself, and then watch your network while the flash player is still active.
You, sir, obviously dont have a clue what you are talking about. For starters, flash isnt even a codec. You're comparing a container to a codec, that's not even apples and oranges, that's apples and boxes.

Well, if streaming media has proved *anything* over the years, it's that the general public doesn't care if the compression ruins the work as long as they can play it for free.
Reference the following:
* RealMedia
* Most Youtube videos, "fan reposts" aka re-encodes, and re-re-encodes
* Low bitrate MP3
* JPEG (ok, it's not streaming, but still - "needs more JPEG artifacts")
* Screeners, cams, and foreign translations from the DIVX Discount Theatre
* Webcams
* Most QuickTime videos
* Most AVIs
* Most streaming video on Flash today
* Cable and satellite delivered HD content
Really, the only thing you need to say is "free" and people will at least give it a try.
Most video codec patents revolve around implementations of the discrete cosine transform, Huffman coding, chroma sub-sampling, and bilinear interpolation. All of these techniques are older than the patent examiners who approved the patents and indeed the judges who will try the cases. It's all mathematics, every last bit. These patents are all essentially equivalent to patenting the tetrahedron.
There is nothing the USPTO will not give a patent for. As such, there is absolutely nothing in the universe past or present which can be declared patent free wherever the authority of the USPTO is recognised.
May the Maths Be with you!
Free Software projects are not likely to be a target in this particular patent battle. Patent lawsuits are expensive, and Free Software projects are unlikely to have the resources to make them workable targets. After all, how do you prove millions in damages from a project given away for free? More importantly, there are plenty of well-funded entities with an interest in protecting Free Software projects in general, and these codecs in particular, from patent attacks. My guess is that if you were sued by MPEG-LA (or whoever) for using of VP8 or Ogg Theora that there would be plenty of companies with deep pockets that would be willing to help pay for excellent legal representation.
You don't honestly think that Google will allow MPEG-LA (or Microsoft, or Apple) to get a precedent setting patent case against some piddly Free Software project that was merely using VP8 (or even Ogg Theora) without at least offering world class legal assistance? It doesn't matter who gets sued over these codecs. Google is going to make sure that whoever it is that gets sued has the best lawyers that money can buy. Suing a Free Software project just guarantees that the patent holders suing 1) look like horrible thugs in front of a jury 2) limit the amount of damages that they can ask for (because the Free Software guy is likely to be much poorer than Google).
In short, there is no upside to suing the little guy, only downside. So if there is a lawsuit it will be against Google, and MPEG-LA (or Apple or Microsoft) would have to be desperate to get to that point.
Talk, on the other hand is cheap. I fully expect a FUD-storm very reminiscent of the one that Microsoft leveled against Linux. Just because Microsoft, Apple, or MPEG-LA say that there are problems, however, does not mean that they are willing to risk a patent war with Google, and that's what it would take to actually back up any threats.
