PFND3D12DDI_CALCPRIVATEVIDEODECODERSIZE_0032 callback function

-description

Used to calculate the size of a video decoder. The D3D runtime allocates memory for storing the drivers CPU object representing the video decoder.

-parameters

-param hDrvDevice

The hardware device being processed.

-param pArgs [in]

The arguments used to create a video decoder.

-returns

Returns the size of the video decoder in bytes.

-remarks

The runtime allocates memory for storing the driver CPU object that represents the video decoder. This method is used to calculate the driver object size.
