LAV CUVIA Decoder Config

LAV CUVID 是一款基于 NVIDIA 硬件加速的免费视频解码器，它使用了 N 卡独有的 CUDA 解码 API ("CUVID") 来实现高品质的硬件解码。

这个插件目前处于早期的开发阶段，但是已经在 NVIDIA 硬件能够支持的主要格式上通过了测试，包括 H264, VC-1, MPEG2 以及 MPEG4-ASP (DivX/Xvid)，逐行隔行扫描的格式都支持，并且可以很好的支持硬件反交错。

特点：

- 硬件解码 H264, VC-1, MPEG2 and MPEG4-ASP 等主流格式；
- 全硬件反交错，包括帧率倍增（Frame Doubling），在对 1080i/60fps 的影片播放中能取得极其流畅的效果；
- 可以与所有渲染器协同工作，包括 madVR ，madVR 是推荐的渲染器，使用它可以获得最好的播放画质

下载：

版本 0.4: 32位

下载后直接以管理员身份运行 install.bat 即可，其实就是注册一个 ax 滤镜。然后在你的播放器，例如 MPC-HD, KMP, PotPlayer 中启用这个解码器即可。

注意，需要 VC++2010 运行库支持。

实际使用效果相当不错，画质比起收费的 CoreAVC 来一点也不逊色，加载速度还稍微快了一点，强烈推荐赶紧装上体验一下！

使用中需要注意的几个问题：

- 请安装最新的显卡驱动，解码器基于 CUDA 3.2 编写，至少需要 260 系列的驱动支持；

- 建议在 Vista 或者 Windows7 下使用, 在 XP SP3 下必须关闭 "DXVA Interop" 选项；

Nvidia VDPAU Feature Sets

Nvidia VDPAU Feature Sets^[12] are different hardware generations of NVIDIA GPU's supporting different levels of hardware decoding capabilities. For all the current feature sets from NVIDIA, the maximum video width and height are 2048 pixels, minimum width and height 48 pixels, and all codecs are currently limited to a maximum of 8192 macroblocks (8190 for VC-1/WMV9). Partial acceleration means that VLD (bitstream) decoding is performed on the CPU" class="mw-redirect" title="CPU">CPU, with the GPU only performing IDCT, motion compensation and deblocking. Complete acceleration means that the GPU performs all of VLD, IDCT, motion compensation and deblocking.

Feature Set A: Complete acceleration for H.264; Partial acceleration for MPEG-1, MPEG-2, VC-1/WMV9
Feature Set B: Complete acceleration for MPEG-1, MPEG-2, VC-1/WMV9 and H.264.; All feature set B hardware cannot decode H.264 for the following widths: 769-784, 849-864, 929-944, 1009-1024, 1793-1808, 1873-1888, 1953-1968, 2033-2048 pixels.
Feature Set C: Complete acceleration for MPEG-1, MPEG-2, MPEG-4 Part 2 (a.k.a MPEG-4 ASP), VC-1/WMV9 and H.264.; Global motion compensation and Data Partitioning are not supported for MPEG-4 Part 2.
