这次不是免费的，需要许可证激活。
DGAVCDecNV runs on Nvidia graphics cards that support CUDA video decoding. This program requires a license that you can obtain from me by donating $15.00 to become a registered supporter of neuron2.net. You may obtain your license by clicking on the donate button below. Note that you do not need to have a PayPal account; you can pay with a credit card account also. After your payment is verified, I will contact you by email to arrange delivery of your license file that activates DGAVCDecNV. Please be aware that until the system is automated I can process activations only twice a day, in the morning and evening, so be patient if your activation seems delayed. Your activation is tied to your system drive that carries the C: partition. So if you replace that drive, please email me for a new license file. Your activation includes all future versions of the program at no cost.

我败，还是Failed to create video decoder。这问题在作者的发布页和doom9都有人问到，可惜现在最的新版还是没能修正此BUG。

Version 1.0.6 changes:

1. Added support for double rate deinterlacing.

2. Released shared memory properly on termination.

3. Fix memory issue causing crash with latest Nvidia drivers.

4. Fix for streams with cropping on the right.

5. Server opens in the system tray.

6. Fix problem with transport streams that have a PES header split between transport packets.

别以为GPGPU就是一成不变的，现在GPU架构的变化比CPU快得多，在CPU频率提高受到工艺瓶颈限制的今天，通过使用高度并行化的处理器来协助CPU进行高密度计算是现在的趋势，否则Intel也不会去费心搞一个X86架构的Larrabee来和NV竞争。

时代是发展的，今天不行不代表未来就不行，几年前你会想到用CUDA去解H.264？

未来很多东西都不一样了，起码现在这东西还不能满足要求

部分算法更是扯淡
先不说在CUDA上的实现是多么困难，就算实现了，CPU和GPU之间的latency就能把所有的速度优势都化为乌有

起码DOOM9已经在讨论了，部分算法转到CUDA上效率要高许多的

Version 1.0.5 changes:

1. Broke out the GPU decoder into a server application. This allows MEGUI and other managed applications to work properly.

淚流滿面的更新啊。。

呵呵，慢慢等待完善吧

求教，喂dgavcdecn v1.04吃h264出现以下提示信息，请问这是什么问题？
