[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

Note This interface is deprecated. New applications should not use it.

The GetCurrentStreamTime method retrieves the current stream time.

HRESULT GetCurrentStreamTime(
  [out] REFERENCE_TIME *pCurrentStreamTime
);

Parameters

[out] pCurrentStreamTime

Pointer to a variable that receives the stream time, in 100-nanosecond units.

Return value

Returns an HRESULT value. Possible values include the following.

Return code	Description
E_POINTER	NULL pointer argument.
S_FALSE	The graph is not running, or there is no reference clock.
S_OK	Success.

Stream time is defined only when the graph is running and has a reference clock. Otherwise, *pCurrentStreamTime is set to zero and the method returns S_FALSE.
