CMediaSample::IsSyncPoint

Determines if the beginning of a sample is a synchronization point.

HRESULT IsSyncPoint(void);

Return Values

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

Remarks

This member function implements the IMediaSample::IsSyncPoint method. It returns the value of the m_dwFlags Sample_SyncPoint property flag. 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.
