DXVACompBufferInfo structure (dxva9typ.h)
Specifies the requirements for compressed surfaces for DirectX Video Acceleration (DXVA).
To get this information, call IDirect3DVideoDevice9::GetDXVACompressedBufferInfo. Each DXVACompBufferInfo structure gives the requirements for a specific DXVA surface type. The surface type is defined implicitly by the index of the array that is passed into the pBufferInfo parameter.
Syntax
typedef struct _DXVACompBufferInfo {
DWORD NumCompBuffers;
DWORD WidthToCreate;
DWORD HeightToCreate;
DWORD BytesToAllocate;
DWORD Usage;
D3DPOOL Pool;
D3DFORMAT Format;
} DXVACompBufferInfo;
Members
NumCompBuffers
The number of surfaces of this type to create.
WidthToCreate
The width of the surface, in pixels.
HeightToCreate
The height of the surface, in pixels.
BytesToAllocate
The size of the surface, in bytes.
Usage
A bitwise OR of one or more D3DUSAGE constants.
Pool
The memory pool in which to create the surface, specified as a D3DPOOL value.
Format
The pixel format, specified as a D3DFORMAT value.
Remarks
To create the compressed surfaces, call IDirect3DVideoDevice9::CreateSurface.
