There are literally billions of dollars at stake. They will pull out all the plugs to combat VP8.

"All video codecs are covered by patents".

What is much more an issue here are software patents altogether. Remember when 'Multimedia' was patented?

It's ridiculous and really U.S. centric. Every piece of software is based on another piece of software. To even go there and state anything based on DCT is patented is nonsense.

I hope they will make this a landmark lawsuit that will severely curtail software patents altogether.

Anyone going to try to make a vpxenc.exe with AviSynth support?

They will certainly try.

Yes.

No.

If you live in some places in Africa or Asia this may be true. But most places not only have binding treaties with the USA on patents, their governments are working directly with the USA to get even stronger ones that are more easily enforced internationally.

To violate a patent requires neither a existing product, existing software, or copying. You can come up with a idea 100% on your own, turn it into a product, and then get sued by a lawyer who never programmed a single line of code in his life and has no products that he sells. He just has to control a patent and you lose.

Don't hold your breath. The current administration is very pro-'intellectual property'. They think that they can use patents to curtail the activities of companies that are competitive with established USA firms.

Which is one of the major things that patents are used for... to stop the small guy from competing. That is why Microsoft, IBM, et al. support patents even though they are the ones that get sued the most. They just past the cost onto their customers and do not have to worry about smaller upstarts competing against them.


Hopefully the Vp8 will succeed and turn video into just another common format. Just a common and easy to use as jpeg, png, gifs, mp3s, and whatever else. That way we can progress and work on more impressive things.

.gifs had licensing issues and .mp3 playback still has to be licensed (why Firefox and Opera don't support it). The .mp3s you see online are in a flash wrapper just like most of the h.264 content.

It looks like psychovisual optimizations are next thing for VP8.

http://blog.webmproject.org/
Quote:
In the next release, we plan to further improve the compression rate at the low bitrate range, as well as focus on new features such as two-pass encoding and visual optimization using segmentation maps.

Also new version of Vorbis Aotuv was realesed with improved audio quality.

“Blueberry” VP8 Hardware Encoder IP Released

"Blueberry," the second release of the H1 VP8 hardware encoder.

Quote:
Technical Details of the Blueberry Release:

We reached the aforementioned +0.82 dB PSNR gains by adding the following features to the encoder:

Improved encoding decisions and added more coding options at macroblock level

Enabled multiple motion vectors per macroblock (Split MV mode)

Added preference of “nearest”, “near” and “zero” type macroblocks that are less expensive to code than others

Added support for up to two reference frames in motion search (immediately previous and Golden frame)

Added deblocking filter macroblock mode adaptivity support

Added ¼ pixel precision motion estimation at 1080p resolution (previously supported only up to 720p)

Increased the amount of token probability tracking counters (enables more efficient entropy coding)

In addition, we added support for a programmable segment map, which enables psychovisual quality optimizations and defining region-of-interests. This means we can for example code the foreground objects (i.e. people) with a better quality (smaller quantizer) than the static background. We also added new hooks to the hardware that allows us to improve the quality of the encoder by later firmware upgrades that optmize our cost function algorithms - even after the chip has been manufactured.

Why is PSNR still the main metrics?
It is well know that it has bad correlation with real visual quality.
Almost no improvement for SSIM.

More WebM Tools

Any Video Converter Version 3.23 (released on May 11, 2011 ), add WebM as supported input and output video format.

Then:

* Non-commercial WebM Tools (Windows): Miro Video Converter, XMedia Recode, Firefogg, MediaCoder.

* Commercial WebM Tools (No cloud soft.): Bigasoft Total Video Converter, Any Video Converter.

Do you know of others?




Sorry my english

From that description they do exactly the opposite of what adaptive quantization in x264 and other encoders does. I hope that's just a result of dumbing it down for the general audience and not something they actually want to do.

Yes, looks like a future VP8 segmentation + bitrate distribution is totally opposite to x264´s mbtree. Although mbtree does good job there are other approachs.
It is a possibility that more optimal way will be smart algorithm in the middle of both.

About optimality of mbtree

Yeah though i find it bad news that Microsoft bought Skype
Skype always drove the VPx for low latency Videoconferencing and im not sure if Microsoft will continue that (actually it would be pretty strange if they would) on the other side with websockets nowadays skypes videoconferencing doesn't matter that much anymore.

They'll probably just bundle Silverlight with Skype in the next version, arguing they can auto switch to various bitrate streams on the fly with it or some other crap....

@mariush
you shouldn't underestimate with what the guys from Beijing might come up with , they worked exactly on this with their Titanium Codec http://research.microsoft.com/en-us/people/yanlu/

I'm not saying multi-bitrate vc1 is bad.. it could be very good. What irks me is that pretty much all technologies end up getting shoved down people's throats, whether they want it or not.

Just today I got a message saying important update available - the only thing was Microsoft Malicious Software whatever it's called.... People have short memory but when Microsoft bought Gecad's IP (rav antivirus) antivirus software makers complained that they'll get out of business and Microsoft said the software will be optional to download from website so it's not a problem. Well, soon it turned to optional software components and now for a long time it's important software update and always checked even if I don't have it installed now.

Now a new thing there in the optional updates is Microsoft Live Essentials... how much time do I have until they'll push it to "important updates" and always checked...
Silverlight is also always checked each week in the optional updates and I have to uncheck it manually just to get the popup stop nagging me.

It's damn annoying and frustrating and makes me lose trust in MS's products so much I don't even care to try these nice technologies they may make.

Imho the technology behind video in skype will change 100% because they have the vc1/h264 hardware decoding in Xbox360 and they'll want to integrate Xbox360 with Skype... and for pc, what better way to implement it than silverlight, which they can just load as a plugin in an embedded html page or something like that. Microsoft is also having patents and is part of the h264/vc1 licensing group so they don't really care that much about royalties...

Microsoft pays VC-1 and H.264 royalties just like everyone else. In fact, it pays more than most since it ships quite a few decoders (i.e. Windows, Xbox, Zune, Silverlight, etc.).
