New code "competing with H.264/AAC to potentially replace MPEG-2" ?

[audyovydeo]

I was looking for info on 3GP when I stumbled upon this :

"Audio Video Standard

Audio Video Standard, or AVS, is a compression codec for digital audio and video, and is competing with H.264/AAC to potentially replace MPEG-2. Chinese companies own 90% of AVS patents. [1]"

http://en.wikipedia.org/wiki/Audio_Video_Standard

let's read on :

"The audio and video files have an .avs extension as a container format."

So I followed up the link : http://www.avs.org.cn/en/index.asp

"... AVS is China independent standard which based on homeland innovative technology and partial public technology. AVS coding efficiency is more than 2-3 time of MPEG-2, and similar with AVC. Moreover the AVS technical plan is succinct; chip is less complex. It also achieves the highest level of second generation. Moreover AVS solved the deadlock of AVC patent permission through the succinct one step permission policy. AVS is the opening national and international standard, easy to promote; In addition, AVC is only one video coding standard, but AVS is a set of integrity standard system which contains system, video, audio and media copyright management in the inside standard system also provides the more comprehensive solution for the digital video and audio industry. In summary, AVS may be one of the best choice of the second generation of source standard...."


Anyone else heard anything about this ... err ... "standard" ??

Jep it's almost entirely based on AVC patents it's actually i think you can call it a lower complex AVC :)

If all it is is a gimped AVC standard then we really don't want this to happen --;

The extension is stupid too. I'm sure at least one of them heard of Avisynth before...

^ The name by itself is stupid. "Audio Video Standard" is pretty dumb.

From what I've seen, yeah, it's like a low-complexity AVC. Kinda "strange" bitstream too, I've seen many people getting errors frequently with the results.

[Comatose]

I don't understand why somebody would go for a low complexity AVC anyway... hardware decoders don't have issues with AVC, so what's the point?
Oh, I get it. You're supposed to be able to read the bitstream and do the decoding in your head!

[CruNcher]

Comatose it has alot of advances going with a low complexity codec for example for mobile devices "longer battery life" less energy usage allready on the decoding side less production cost @ the decoder chip level (and all this doesn't in the end have to mean lower visual quality if it's correctly done) and i guess the chinese researched alot into this. It's harder to create such a balanced standard then to overoptimize something especialy as the field of digital video its perception and how much energy it needs is still a very young one i guess the chinese will bring us in the future alot of advancements out of their labs/universities on these matters and i guess they will be the ones that also bring us new metrics based on this research.
I wouldn't underestimate AVS yet lets wait and see how much Developer are interested in working on it (most probably we will se alot of chinese working on it) and a Advanced Encoder the same goes for Dirac tough i would prefer advaned process in Dirac Development more then AVS (as it's still patent crowded by alot of the AVC especialy Asia patents)

Wow, this is 1 year old news. See my post from last year (http://forum.doom9.org/showthread.php?p=1050219#post1050219) for links to the SDK and the codec. The site is on chinese and needs a registration to join the AVS group. From my tests the quality is very good and can nearly compete with AVC at high data rates (> 6.5 MB/s for 720p and > 9 MB/s for 1080p). For those of us who need to pay AVC royalties, AVS can be very interesting. Why rant on things you don't understand? BTW, some comments here on extensions and names are silly. You simply don't get it.

[CruNcher]

Yeah and also we had the first discussion about the Standard here (patents,royalities,complexity) i think http://forum.doom9.org/showthread.php?t=112792 and the OpenAVS SF.net project
tough crypto the .avs extension is a problem with their dshow parser as it tries to open avisynth files and crashes the player application (even creates a loop) :) maybe they fixed that by now tough.

What is there to get? The container extension is AVS, and so is Avisynth's. On a computer using both the codec and Avisynth, one will have to go.

Well, H.264 already has restricted profiles/levels, which are suitable for mobile devices. So there should be no need for a new "low complexity" standard...

Ok, I got that. Cruncher also pointed that out. But I am not sure, what is going wrong. DirectShow and DS filters decide on content, not on file extensions.
