IMFSinkWriter::SendStreamTick method (mfreadwrite.h)

Indicates a gap in an input stream.

Syntax

HRESULT SendStreamTick(
  [in] DWORD    dwStreamIndex,
  [in] LONGLONG llTimestamp
);

Parameters

[in] dwStreamIndex

The zero-based index of the stream.

[in] llTimestamp

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.

Return value

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

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.

This interface is available on Windows Vista if Platform Update Supplement for Windows Vista is installed.
