IMediaSample::IsSyncPoint (Compact 2013)

  • Article

3/26/2014

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 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).
