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
