IMediaSample::IsSyncPoint (Windows CE 5.0)
This method determines if the beginning of a sample is a synchronization point.
HRESULT IsSyncPoint(void);
Parameters
None.
Return Values
Returns S_OK if the sample is a synchronization point and S_FALSE if not; otherwise, returns an HRESULT error value.
Remarks
If the bTemporalCompression member of the AM_MEDIA_TYPE structure is FALSE, all samples are synchronization points. A filter can begin a stream at any synchronization point.
While calling SetSyncPoint with a value of TRUE (1) sets the synchronization point, calling IsSyncPoint on a synchronization point sample returns S_OK (0).
Requirements
DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.
