[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]

The GetParseTime method retrieves the current stream parse time. For MPEG-2, this corresponds to the system clock time computed for the current stream position.

Syntax

HRESULT GetParseTime(
  [out] REFERENCE_TIME *prtCurrent
);

Parameters

[out] prtCurrent

Pointer to the current parse time.

Return value

Returns an HRESULT value. Possible values include the following.

Return code	Description
S_OK	Success.
VFW_E_NOT_CONNECTED	The parse time is not available, because the input pin is not connected

Remarks

The parse time for the MPEG-2 Splitter filter is the current stream position in system clock units. The initial value of the parse time is zero.
