Description

Specifies driver-specific data for the extended Microsoft DirectX Video Acceleration (DXVA) decoding function that is provided by a call to the VideoDecoderExtension function.

Members

`Function`

The function number. This number identifies the operation to perform. Currently no function numbers are defined.

`pPrivateInputData`

A pointer to a buffer that contains input data for the driver.

`PrivateInputDataSize`

The size of the buffer pointed to by pPrivateInputData, in bytes.

`pPrivateOutputData`

A pointer to a buffer that the driver can use to write output data.

`PrivateOutputDataSize`

The size of the buffer pointed to by pPrivateOutputData, in bytes.

`ResourceCount`

The number of elements in the pResourceList array. If pResourceList is NULL, set ResourceCount to zero.

`pResourceList`

A pointer to an array of resource handles. Use this member to pass Direct3D resources to the driver.

Remarks

The exact meaning of each structure member depends on the value of Function.
