Syntax

  HRESULT get_VideoHeight(
    long *pVideoHeight
);

Parameters

pVideoHeight

Pointer to the height of the native video, in pixels.

Return Value

Returns NOERROR if successful or E_OUTOFMEMORY if there is not enough memory available.

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