IMediaSample::IsSyncPoint (Windows Embedded CE 6.0)

1/6/2010

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).

Requirements

Windows Embedded CE Windows CE 2.12 and later
Note Microsoft DirectShow applications and DirectShow filters have different include file and Library requirements
For more information, see Setting Up the Build Environment, Version 2.12 requires DXPAK 1.0 or later
