This method determines if the beginning of a sample is a synchronization point.

Syntax 

HRESULT IsSyncPoint(void);

Parameters

None.

Return Value

Returns S_OK if the sample is a synchronization point and S_FALSE if not; otherwise, returns an HRESULTerror value.

Remarks

If the bTemporalCompressionmember of the AM_MEDIA_TYPEstructure is FALSE, all samples are synchronization points. A filter can begin a stream at any synchronization point.

While calling SetSyncPointwith a value of TRUE (1) sets the synchronization point, calling IsSyncPointon a synchronization point sample returns S_OK (0).
