# DXVA-HD sample

This sample demonstrates DirectX Video Acceleration High Definition (DXVA-HD). DXVA-HD is a low-level video processing API.

This sample is essentially a port of the DXVA2_VideoProc sample to use the DXVA-HD interfaces. It has the same basic functionality, and most of the keyboard commands are the same.

DXVA-HD has additional capabilities that make it more powerful for video processing than the original DXVA-VP APIs introduced in Windows Vista:

- Any stream can be either RGB or YUV.
- Any stream can be either progressive or interlaced.
- The background color can be RGB.
- Luma keying.
- The device can switch between blend, bob, and adaptive deinterlacing.
- Mandatory output formats: X8R8G8B8 and A8R8G8B8
- Mandatory input formats: X8R8G8B8, A8R8G8B8, YUY2 and AYUV

3. In the Build menu, select Build Solution. The application will be built in the default \Debug or \Release directory.

## To run the sample

1. Navigate to the directory that contains the new executable, using the command prompt or Windows Explorer.
2. Type DXVA_HD.exe at the command line, or double-click the icon for DXVA_HD.exe to launch it from Windows Explorer.

Command line options:

```cmd
-hh : Hardware Direct3D device and hardware DXVA-HD device.
-hs : Hardware Direct3D device and software DXVA-HD device.
-ss : Software Direct3D device and software DXVA-HD device.
```
