- 5.  Notes
======================================================
NOW..... It's a Girl!! Congrats Blacksun!!

- 6.  Known or Possible issues
======================================================
- Haali's splitter has been reported to not install on Windows 7. We are looking into the issue.
- CUDA does not handle interlacing at this time and the decoder will fall back to software decoding.
- Non-compliant H.264/AVC Motion Vectors are not supported. Some HD video's are using mastering/encoding with 'out of spec' encoders.
It is not really a bug.... but more of an FYI if you find such encodings.

COREAVC 很好很强大！！

NV 网站也被某种水产了？

好事啊。。。。。。。

希望CUDA越来越普及。。。。。。。^_^

CUDA前途未卜
我看NV就是把The Way的钱拿出来拉拢一些厂商和媒体造势而已.
就像棒子那样NV把什么都误导成自己的CUDA,这势造起来了,NV就会越加努力.如果造不起来,那CUDA八成会突然死亡

CoreAVC is being recognized as being the world's fastest H.264 software video decoder. Now featuring NVIDIA CUDA Support!

呵呵不知道要搞什么把戏 coreavc本身定位是软解和CUDA扯上什么关系？如果是 ...

进coreavc论坛看。
那个GPU Support 说的是DxVA.

On DXVA..... we are not believers in DXVA and feel the technology must die now. Solutions like CUDA are based on a more universal approach and that allowing MS to create such enabling hooks like DXVA is dangerous (from a control perspective), and better created at the hardware level with simple driver hooks in software (the way it should be).

ATM CUDA is still maturing and we are working directly with the NVIDIA engineers on the issues that we are finding. However the biggest benefit for the first few releases will be 'one core' CPU users for sure. We are seeing a 30%+ increase in performance while dual core users are only getting single digit increases. This is mostly due to the current limitations in CUDA but they are being addressed as we speak and we hope to be able to spread over load even better across all CPU/GPU's.

We will be releasing the first NVIDIA CUDA enable versions in the CoreAVC 1.9.x releases. Then, we will release the 'final' CUDA versions in our 2.0 releases of CoreAVC.

其实就画质来讲，本身就不会因为解码器调用了CUDA而得到任何提升，也就是CPU解码负担减轻了。

但问题是，目前低端的E2系列或者E5系列，都能够轻松胜任软解高清工作。那么。。。这个技术也许只有老的P4用户能够得益了。

CUDA？只有N卡能跑，Computer Shader和openCL，N卡，A卡和今后的intel，S3的等卡都能跑，CUDA还会有前途吗？怎么和所有GPU包括NV自己都支持的通用GPGPU编程接口竞争？当年如日中天的3dfx的Glide干得过DirectX和OpenGL吗？更何况根本没有壮大的CUDA，同样Stream也没花头，但是AMD看得很明白，对stream只是敷衍了事，根本没投多大资源，注定没有希望的东西，AMD不会像NV这么蠢，想逆天而行，花了大量的资源，妄图让自己的独家标准和MS和很多厂商包括自己也支持的通用标准竞争。

NV如果像MS那样市场占有率95%以上，OK，他的标准就是市场标准，可是他不是微软，她的GPU占有率远远达不到windows这样的垄断性占有率，而他自己又支持Computer shader和OpenCL，软件公司只要用CS或OpenCl编程，就可以在N卡，A卡，Intel显卡，S3等显卡上跑GPGPU，如果用CUDA编程，只能在N卡上跑GPGPU，你是软件公司怎么做？难道不想让自己的软件产品在更广的平台上跑？吊死在N卡一家上？可能吗？

当前的GPGPU市场？当前有多少GPGPU市场，GPGPU市场真正有市场是在GPGPU工业标准真正确立推广后才会有像样的市场，这个标准windows平台上只能是DX11的CS，其他平台上的OpenCL，决不会是CUDA和Stream。

kvip 发表于 2009-2-10 21:45

是你在偷概念吧，我什么时候说过冲突了？
一个软件开发商，用CS和OPENCL就可以在所有GPU上跑，也包括NV的GPU，那他为什么还要用CUDA开发应用程序？不要A和Intel的GPU的市场了？或者再用CS和OpenCl为A和I的GPU再开发代码，而其实这些CS和OPENCL的代码N的GPU也能跑，这不是脱裤子放屁吗，软件企业吃饱了撑的，为你NV的GPU单独用CUDA开发代码？不计算工作量和成本了？独占的标准什么时候都打不赢通用的标准，除非是MS这种windows占95%以上平台的垄断企业，他的独占标准就是整个市场的标准，所以也就是事实上的市场工业标准。

标准是否有生命力取决于符合这个标准的产品是否能比竞争对手更好的符合用户的需要。cs和opencl编出来程序，在a和i上的硬件上跑，效能不如nv硬件+cuda的话，为什么不用nv的？nv如果能保持gpgpu的领先地位，cuda成为一个有生命力的gpgpu标准不成问题。和其他标准共存也属于正常。

tnt2/tnt不跑dx可以跑nv自己的图形接口标准，3dfx可以搞glide，nv自建标准有什么不可以？
westlee 发表于 2009-2-10 22:05

行业标准很多时候不一定是效能最好的标准，就像X86，windows，其实性能都不如竞争标准比如IBM的powerPC和unix/linux，再有当时的DX真的比Glide更好吗？，就算NV+CUDA比A+CS强，CUDA也没有希望，因为NV自己也支持CS，而有MS支持的CS，其SDK库和程序开发手册是NV根本无法匹敌的，这点微软有先天优势，他就是干软件这个活的，由此而使软件开发商在软件开发上可以节省大量的成本。再说了，NV+CUDA真的比A+CS好吗？谁也不敢确定。
tnt2/tnt如果不跑dx，而跑NV自己的图形接口标准，那么，3dfx的voodoo卡现在还将存在，凭当时的NV的实力，像自己搞个图形接口标准和3dfx的glide竞争，无异于异想天开

我什么时候说过CUDA和CS及OPENCL不能同时存在了？可以同时存在，就像当年glide和dx还有opengl可以同时在windows上存在阿，关键是，软件开发商会用什么接口去编程，用CS就可以全部搞定N卡A卡和I卡，那干吗多花工作时间再为N卡多用CUDA去编程？吃饱了撑的？当年游戏开发商只要用DX编程，就可以在N卡，3dfx和A卡，M卡，S3卡等所有卡上跑，而其实用Glide编程在voodoo上效率更高，画面更好（N卡当时就是啊傻快，跑极品飞车2SE和3，DX的画面和速度完全无法和glide下的voodoo卡比），但是却越来越少的游戏开发商用glide，道理就在这里。

软件开发商不会为了N卡就用CUDA，为了A卡就用stream，他们只会用CS和OPENCL，可以在N卡，A卡和I卡及所有的卡上跑，这样可以节省大量的编程时间，工业标准是用来干什么的，就是干这事的。同一标准，同一接口，同一编程，CUDA或stream还可以再存在一段时间，但是最终，企业标准如果不能成为行业标准，都免不了被淘汰。

你不要跟我说现今，当初还所有3D游戏全用Glide编程呢，最后呢？
就拿PS CS4来说，adobe如果要用N的GPU加速，就要用CUDA，要用A的GPU加速（Adobe不会放弃A的GPU的，A的GPU也是有相当市场占有率的），那就要用stream编程，下次I的拉拉比出来了，要用I的GPU加速，I好像没有提出自己GPGPU标准，肯定用CS或OPENCL了，那Adobe就要为每一家GPU厂家都编程？其实只要用CS或OPENCL，就可以搞定所有GPU了，一个企业从软件开发成本和维护成本上来说，adobe将来要使用GPU加速的时候会怎么选择？明摆着的事情。独有企业标准之所以干不过通用标准，就是这个道理，就算独有企业标准有着更高的效率，成不了行业标准，最终只会被淘汰。
