IMediaSample::IsDiscontinuity method (strmif.h)

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The IsDiscontinuity method determines if this sample represents a break in the data stream.

Syntax

HRESULT IsDiscontinuity();

Return value

Returns S_OK if the sample is a break in the data stream. Otherwise, returns S_FALSE.

Remarks

A discontinuity occurs when a filter seeks to a different place in the stream, or when a filter drops samples for quality control.
