CBasePin::Run

The Run method notifies the pin that the filter is now running.

Syntax

  HRESULT Run(
    REFERENCE_TIME tStart
);

Parameters

tStart

Start time as passed to the filter's IMediaFilter::Run method.

Return Value

Returns S_OK.

Remarks

When the filter goes from paused to running, the CBaseFilter class calls this method on all of the filter's pins.

This method does nothing in the base class. Derived classes can override this method. For example, a pin might start a worker thread that delivers samples.

The filter graph manager's internal state is not updated until after this member function returns, so do not test the state from this method.

Requirements

**  Header:** Declared in Amfilter.h; include Streams.h.

**  Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
