IWMHeaderInfo::AddMarker

The AddMarker method adds a marker, consisting of a name and a specific time, to the header section of the Windows Media file.

Syntax

HRESULT AddMarker(
  WCHAR*  pwszMarkerName,
  QWORD  cnsMarkerTime
);

Parameters

pwszMarkerName

[in] Pointer to a wide-character NULL-terminated string containing the marker name.

cnsMarkerTime

[in] Specifies the marker time in 100-nanosecond increments.

Return Values

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.

Return code	Meaning
NS_E_INVALID_STATE	The writer cannot currently be configured.
E_UNEXPECTED	The method failed for an unspecified reason.

Remarks

For the reader, all of the Add, Set, and Remove calls always return E_NOTIMPL.

For the writer, Add, Set, and Remove can only be called before BeginWriting. The writer does not support markers, and all of the marker calls (including AddMarker) return E_NOTIMPL.

The metadata editor fully implements all of the methods.
