CBaseFilter::StreamTime
The StreamTime method retrieves the current stream time.
Syntax
virtual HRESULT StreamTime( CRefTime& rtStream );
Parameters
rtStream
Reference to a CRefTime object that receives the current stream time.
Return Value
Returns an HRESULT value. Possible values include those listed in the following table.
Value | Description |
S_OK | Success. |
VFW_E_NO_CLOCK | No reference clock is available. |
Remarks
Stream time is defined as the current reference time (as given by the reference clock) minus the start time (specified by CBaseFilter::m_tStart). A media sample's time stamp specifies the stream time when it should be rendered. If a sample with a time stamp less than the current stream time has not yet been rendered, it is late.
Requirements
** Header:** Declared in Amfilter.h; include Streams.h.
** Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
