      Sets the pipeline for the webcam which can process the data stream coming in from the webcam.
      Parameters:
      pipeline - The pipeline to use to process data.

    • clearPipeline

      public void clearPipeline()
      Unsets the webcam pipeline; no data will be able to be processed since there is no pipeline active.

    • getPipeline

      public AbstractResultCvPipeline<?> getPipeline()
      Gets the current active pipeline of the webcam.
      Returns:
      The current active pipeline.

    • close

      public void close() throws Exception
