template<typename TOutputVideoStream>
class itk::VideoSource< TOutputVideoStream >
A TemporalProcessObject that produces a VideoStream.
VideoSource acts as the base class for all TemporalProcess objects that produce a VideoStream as their output. This class defines GetOutput() which returns a pointer to the VideoStream object on output port 0.
The other role that VideoSource plays is to implement the framework for spatial streaming to complement the temporal streaming implemented in TemporalProcessObject. This implementation mirrors the implementation in ImageSource except that each thread will be able to operate on a spatial region of each frame in the current temporal region that is being processed.

template<typename TOutputVideoStream >
ThreadedGenerateData here serves the same semantic purpose as ThreadedGenerateData in ProcessObjects that handle Images. This is to say that ThreadedGenerateData is in charge of performing a single algorithmic operation on a portion of the requested region. The difference will come in the implementation of each filter. Subclass implementations must access the passed spatial region across the desired number of frames in the buffered TemporalRegion of the input.
WARNING: subclasses may need to handle the case where different frames have different spatial dimensions and thus some frames may not be accessible at the requested spatial region.
Reimplemented in itk::FrameAverageVideoFilter< TInputVideoStream, TOutputVideoStream >, and itk::FrameDifferenceVideoFilter< TInputVideoStream, TOutputVideoStream >.
