Value Description
E_FAIL Failure.
E_POINTER Null pointer argument.
E_INVALIDARG Invalid argument.

S_OK or NOERROR Success.


Discontinuous samples occur when a source filter seeks to a different place in the media 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).
