Indicates a gap in an input stream.
- dwStreamIndex [in]
The zero-based index of the stream.
- llTimestamp [in]
The position in the stream where the gap in the data occurs. The value is given in 100-nanosecond units, relative to the start of the stream.
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
For video, call this method once for each missing frame. For audio, call this method at least once per second during a gap in the audio. Set the MFSampleExtension_Discontinuity attribute on the first media sample after the gap.
Internally, this method calls IMFStreamSink::PlaceMarker on the media sink.
