IAMTimelineTrack::GetNextSrc method

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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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

[Deprecated. This API may be removed from future releases of Windows.]

 

The GetNextSrc method searches the track for the next source that appears at the specified time or later.

Syntax

HRESULT GetNextSrc(
  [out] IAMTimelineObj **ppSrc,
        REFERENCE_TIME *pInOut
);

Parameters

ppSrc [out]

Receives a pointer to the source object's IAMTimelineObj interface.

pInOut

Pointer to a variable that contains the start time for the search, in 100-nanosecond units. If the method retrieves a source, it sets the value to the stop time of the source. If the method does not retrieve a source, the value becomes invalid and the application should not use it.

Return value

Returns S_OK if the method retrieves a source, or S_FALSE otherwise.

Remarks

If the time specified by pInOut falls between the start and stop times of a source, the method retrieves that source.

If the method returns S_OK, the IAMTimelineObj interface that it returns has an outstanding reference count. Be sure to release the interface when you are finished using it.

Note

The header file Qedit.h is not compatible with Direct3D headers later than version 7.
