PFND3DWDDM2_0DDI_VIDEODECODERSUBMITBUFFERS1 callback function (d3d10umddi.h)
VideoDecoderSubmitBuffers1 submits one or more buffers for decoding.
Syntax
PFND3DWDDM2_0DDI_VIDEODECODERSUBMITBUFFERS1 Pfnd3dwddm20DdiVideodecodersubmitbuffers1;
HRESULT Pfnd3dwddm20DdiVideodecodersubmitbuffers1(
D3D10DDI_HDEVICE hDevice,
D3D11_1DDI_HDECODE hDecode,
UINT BufferCount,
const D3DWDDM2_0DDI_VIDEO_DECODER_BUFFER_DESC1 *pBufferDesc
)
{...}
Parameters
hDevice
A handle to the display device (graphics context). The Direct3D runtime passed the user-mode driver this handle as the hDevice member of the D3DDDIARG_CREATEDEVICE structure at device creation.
hDecode
A handle to the video decoder object that was created through a call to the CreateVideoDecoderDDI.
BufferCount
The number of buffers in the array that is referenced by the pBufferDesc member.
pBufferDesc
A pointer to an array of one or more D3DWDDM2_0DDI_VIDEO_DECODER_BUFFER_DESC1 structures.
Return value
Returns one of the following values:
| Return code | Description |
|---|---|
| S_OK | Private driver data was successfully returned. |
| E_OUTOFMEMORY | Memory was not available to complete the operation. |
Remarks
The pBufferDesc member points to an array of one or more D3DWDDM2_0DDI_VIDEO_DECODER_BUFFER_DESC1 structures. Each element in the array describes a compressed video frame buffer that is submitted for decoding.
