This method determines if there is discontinuity in the data stream.

HRESULT IsDiscontinuity(void);



Return Values

Returns S_OK if the sample is a discontinuous sample, or S_FALSE if not; otherwise, returns an HRESULT error value.


Discontinuity occurs when a source filter seeks to a different place in the stream or when a filter drops samples for quality control.

While calling SetDiscontinuity with a value of TRUE (1) sets the discontinuity property, calling IsDiscontinuity on a discontinuous sample returns S_OK (0).


DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
