Google Enables VP9 Video Codec In Chromium
An anonymous reader writes "Last month, Google revealed that it was planning to finish defining its VP9 video codec on June 17 (today), after which it will start using the next-generation compression technology in Chrome and on YouTube. The company is wasting no time: it has already enabled the free video compression standard by default in the latest Chromium build."
A very positive development, to be able to get away from flash and that nasty proprietary plugin. With Adobe basically thumbing their nose at Linux users, getting away from flash is something that ought to be encouraged. So When will Firefox add this for those who prefer that browser?
It's not the disaster that VP8 was (which looked like a codec from 10+ years ago), but it seems to be at best in the same ballpark as x264. VP9 isn't really a viable replacement for h.265, but it might do better than their last attempt merely by not being a laughable joke like VP8.
Mind you, I'm not saying VP8 is bad in and of itself. I certainly couldn't do better. But Google promoted it as being superior to h.264, which was an absurd assertion, hence the derision.
VP8 is really slow. Unknown if reason is lack of hardware support or if codec is actually poorly designed. What are reasons VP9 is good versus H264? Yes I know VPx is not "patent-encumbered" --- well except it is except Google made some sort of "deal" with someone to license applicable patents or something.
Why is VP9 any good and why should people care? Is it poor man's H264 or is it H264's peer? Thanks to wise person who knows and answers this.

VP9 will be completely open. Just remember that creating video codecs is very complex process on its own, so adding things like encryption schemes will likely require a bunch of professional engineers.
I'm not sure what to take away from that statement about "professional engineers".
It seem like you implying that since VP9 didn't want/need "the community" (of presuably unprofessional folk) in its development that somehow the current developers of VP9 don't feel that "the community" can develop an encryption schemes (being the unprofessional folk we are)?
I gather that the Cathederal mechanism of development might be deemed necessary (by google) to avoid IP contamination of VP9, but as someone that does stuff in this area (video compression and encryption) professionally, what you seem to be implying is a bit condecending to "the community" of open source developers (many of whom are professional engineers in our day-jobs)...
In fact, I might argue that encryption schemes are best done in the community (e.g., like the AES and the SHA-3 process) because an open competitive environment is the best way to assure the actual difficulty of cirvumenting the scheme is known (rather than assuming that some experts have it figured out).
It may be a technically good codec (I have no strong opinion on that either way). But I see issues with the many devices (tablets, bluray players with usb input, set top boxes, phones...) available whose graphical processors are totally geared towards implementations of mp4 and h264. For example, I understand that an iphone would do battery-efficient hardware decoding of such files. I assume that dfor this new codec the processor will need to do all the work, with likely a much bigger impact on the battery.
VP9 is still a work in progress, so no hard numbers as yet. One of its goals is to achieve 50% better quality with the same bitrate compared to VP8. Another goal is to provide a better encoding efficiency than H.265 which has the same approach on achieving a better quality around 50% compared to H.264.
Google actually did a direct comparison between VP9 and H.264 on a sample file at its recent I/O event and showed off a 63% reduction in file size. As for the quality, see the pic for yourself.
As for the licensing issue, Google cut a deal with the MPEG-LA consortium that controls H.264 to licence their patents for VP8 and VP9. So there is low possibility of any user of VP9 of being bogged down by patent lawsuits.
Why should you care? Unlike H.265, VP9 is free for commercial use . If your use is non-profit, there is no difference between the two.
I don't disagree with you on the merits of the x264 encoder (open source, etc) but are you sure that x.264 is free? Because it seems from this webpage that you need to pay for a licence to use it.
Also, from the H.264 standard itself is not free. The party who makes the encoder and the party who distributes the encoded file to the end users for commercial use has to pay for licensing.
Although H.264 is an open standard, in that it was developed by a consortium of companies and anyone can make and sell an encoder or decoder, it's not free -- you've got to pay for a royalty fee to use it, and the rates are set by the MPEG-LA, which collects payments and distributes them to its members.
V8 and V9 are not the same. V8 itself may have a bad history and be a crap codec, performance wise. Is V9 a bad codec as well, performance wise? Has Google done anything that justifies the wholesale boycott of V9?
x264, the open-source H264 encoder, is the best video encoder on the planet. x264 gives the best quality for filesize. x264 gives the best quality for encoding speed. x264 gives the best quality for low latency streaming. x264 does it all, and does it fantastically well.
x264 is free. x264 does NOT come from the NSA R+D division we know as Google.
Aaaand all that is irrelevant. It doesn't matter if x264 is open-source, it's still patent-encumbered. In any country where the H.264 - patents are valid x264 is infringing on them.
h264 would be ideal, if not for the patent issue. That's a real deal-breaker for many. It's why Firefox doesn't have support for h264 video - even if they applied for a license, they wouldn't then be able to sub-license to developers who want to fork the project, which is incompatible with the open-source development model.
You underestimate just how much crappier MPEG2 is. That technology is very primative compared to modern codecs. To match the quality of h264 takes around ten times the bitrate, based on some rather unscientific estimates from my watching DVDs (mpeg2, 6GB) vs dvd rips (About the same quality, 600MB). That high a bitrate just isn't cost-effective, even today.
I was looking at the API. I couldn't figure out what this function did:
int streamCameraFeedToCIACommaNSACommaAndFBI();

Switch user agent to iPad, it works in 95% of the time.
And the other 5% of the time, it's either A. not a video but a vector animation (which Flash still does better than HTML5), B. available in H.264 (which the Free browsers don't support) and not VP8, or C. intentionally unavailable on iPad because the publisher is a...
