IMediaSample::IsSyncPoint method

The IsSyncPoint method determines if the beginning of this sample is a synchronization point.

Syntax


HRESULT IsSyncPoint();

Parameters

This method has no parameters.

Return value

Returns S_OK if the sample is a synchronization point. Otherwise, returns S_FALSE.

Remarks

A filter can begin a stream at any synchronization point. With some compression types, streaming can begin only at certain points in the stream; for example, on key frames. If the bTemporalCompression member of the AM_MEDIA_TYPE structure is FALSE, all samples are synchronization points.
