Description

A client driver's PFND3D12DDI_CALCPRIVATEVIDEOENCODERHEAPSIZE_0080_2 callback function calculates the required amount of memory needed for the driver's object that represents the video encoder heap.

Parameters

hDrvDevice [in]

Handle for the D3D12 device.

pCreationArgs [in]

Pointer to a D3D12DDIARG_CREATE_VIDEO_ENCODER_HEAP_0080_2 structure that contains the video encoder heap creation parameters.

Return value

Returns the number of bytes needed to store the driver's object that represents the video encoder heap.

Remarks

On return, the D3D12 runtime will allocate the memory needed to store the driver's object and then call PFND3D12DDI_CREATEVIDEOENCODERHEAP_0080_2 to create the actual object.

See D3D12 video encoding for general information.
