View the official Windows Driver Kit DDI referenceNo description available.
Performs a video processing operation on one or more input samples and writes the result to a Direct3D surface.
unnamedParam1hDevice [in]
A handle to the display device (graphics context).
unnamedParam2hVideoProcessor [in]
A handle to the video processor object that was created through a call to the CreateVideoProcessor function.
unnamedParam3hOutputView [in]
A handle to the resource for the output view of the video processor. This handle was created through a call to the CreateVideoProcessorOutputView function.
unnamedParam4OutputFrame [in]
The zero-based index of the output video frame.
unnamedParam5StreamCount [in]
The number of input streams to process in the array referenced by the pStream parameter.
Note The maximum value of this parameter is specified by the MaxStreamStates member of the D3D11_1DDI_VIDEO_PROCESSOR_CAPS structure. The maximum number of streams that can be enabled at one time is given in the MaxInputStreams member of that structure.
unnamedParam6pStream [in]
A pointer to an array of D3D11_1DDI_VIDEO_PROCESSOR_STREAM structures that contain information about the input streams.
VideoProcessorBlt returns one of the following values:
| Return code | Description |
|---|---|
| S_OK | The video processing operation completed successfully. |
| E_OUTOFMEMORY | Memory was not available to complete the operation. |
The VideoProcessorBlt performs all of the video processing based on the stream states and bit-block transfer (bitblt) states that have been previously set.
The Microsoft Direct3D runtime performs the following data validation before it calls the driver's VideoProcessorBlt function:
If the video processor has been enabled to produce stereo samples, the output view must contain a texture array of two elements. Also, at least one stereo stream must be specified.
If the video processor has been disabled from producing stereo samples, the output view must contain a single element. Also, the stereo format cannot be configured as D3D11_VIDEO_PROCESSOR_STEREO_FORMAT_MONO.
Note A video processor is enabled or disabled for the production of stereo samples through a call to VideoProcessorSetOutputStereoMode.
Each input stream is specified through a D3D11_1DDI_VIDEO_PROCESSOR_STREAM structure. If the stereo format of the input stream is configured to be D3D11_1DDI_VIDEO_PROCESSOR_STEREO_FORMAT_SEPARATE, the pInputSurfaceRight member must not be set to NULL. Otherwise, the pInputSurfaceRight must be set to NULL.
Note The stereo format for an input stream is configured through a call to VideoProcessorSetStreamStereoFormat.
If multiple input streams are enabled and the video processor is enabled to produce stereo output, it is possible that one of the input streams may be a mono sample.
Note This function does not honor a D3D11 predicate that may have been set.
