IAMTimelineTrack::SrcAdd 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SrcAdd method adds a source to the track.
Syntax
HRESULT SrcAdd(
IAMTimelineObj *pSrc
);
Parameters
-
pSrc
-
Pointer to the source object's IAMTimelineObj interface.
Return value
Returns S_OK if successful. Returns E_NOINTERFACE if the object is not a source object. Otherwise, returns an HRESULT value indicating the cause of the error.
Remarks
Set the source's start and stop times before calling this method. (Call IAMTimelineObj::SetStartStop.)
Currently, DES cannot simultaneously render more than 75 sources that were compressed with Video Compression Manager (VCM) codecs. Also, if the project as a whole contains more than 75 such sources, you must use dynamic reconnection or DES cannot preview the project. For more information, see IRenderEngine::SetDynamicReconnectLevel.
Note
The header file Qedit.h is not compatible with Direct3D headers later than version 7.
Note
To obtain Qedit.h, download the Microsoft Windows SDK Update for Windows Vista and .NET Framework 3.0. Qedit.h is not available in the Microsoft Windows SDK for Windows 7 and .NET Framework 3.5 Service Pack 1.
