ID3D11VideoContext::VideoProcessorGetStreamOutputRate method

Gets the rate at which the video processor produces output frames for an input stream.

Syntax


void VideoProcessorGetStreamOutputRate(
  [in]   ID3D11VideoProcessor *pVideoProcessor,
  [in]   UINT StreamIndex,
  [out]  D3D11_VIDEO_PROCESSOR_OUTPUT_RATE *pOutputRate,
  [out]  BOOL *pRepeatFrame,
  [out]  DXGI_RATIONAL *pCustomRate
);

Parameters

pVideoProcessor [in]

A pointer to the ID3D11VideoProcessor interface. To get this pointer, call ID3D11VideoDevice::CreateVideoProcessor.

StreamIndex [in]

The zero-based index of the input stream. To get the maximum number of streams, call ID3D11VideoProcessorEnumerator::GetVideoProcessorCaps and check the MaxStreamStates structure member.

pOutputRate [out]

Receives a D3D11_VIDEO_PROCESSOR_OUTPUT_RATE value that specifies the output rate.

pRepeatFrame [out]

Receives a Boolean value that specifies how the driver performs frame-rate conversion, if required.

ValueMeaning
TRUE

Repeat frames.

FALSE

Interpolate frames.

 

pCustomRate [out]

A pointer to a DXGI_RATIONAL structure. If the output rate is D3D11_VIDEO_PROCESSOR_OUTPUT_RATE_CUSTOM, the method fills in this structure with the exact output rate. Otherwise, this parameter is ignored.

Return value

This method does not return a value.
