PFND3DDDI_SETDECODERENDERTARGET callback function (d3dumddi.h)
The SetDecodeRenderTarget function sets the render target surface for decoding operations.
Syntax
PFND3DDDI_SETDECODERENDERTARGET Pfnd3dddiSetdecoderendertarget;
HRESULT Pfnd3dddiSetdecoderendertarget(
HANDLE hDevice,
const D3DDDIARG_SETDECODERENDERTARGET *unnamedParam2
)
{...}
Parameters
hDevice
A handle to the display device (graphics context).
unnamedParam2
pData [in]
A pointer to a D3DDDIARG_SETDECODERENDERTARGET structure that describes the decode render target surface.
Return value
SetDecodeRenderTarget returns one of the following values:
| Return code | Description |
|---|---|
| S_OK | The render target surface is successfully set. |
| E_OUTOFMEMORY | SetDecodeRenderTarget could not allocate the required memory for it to complete. |
Remarks
The SetDecodeRenderTarget function can be called only outside of a DecodeBeginFrame/DecodeEndFrame block.
Decode render targets are always created atomically through calls to the CreateResource function, where all of the decode buffers are indexes within a single resource. All decode render targets are created by setting the D3DDDI_RESOURCEFLAGS.DecodeRenderTarget bit-field flag in the Flags member of the D3DDDIARG_CREATERESOURCE structure.
