The CreateRecorder method creates a new Recording object. Recording objects are used to create permanent files from the stream buffer.


HRESULT CreateRecorder(
  LPCWSTR  pszFilename,
  DWORD  dwType,
  IUnknown**  pRecordingIUnknown



[in]  Pointer to a null-terminated wide-character string that contains the file name for the recording.


[in]  Indicates the type of recording to create, either a reference recording or a content recording. Specify one of the following values.

Value Description
RECORDING_TYPE_REFERENCE Reference recording. A reference recording is created from temporary backing files that have already been recorded. It uses a stub file to reference the existing files. Because a reference recording refers to existing content, the start time can be in the past.
RECORDING_TYPE_CONTENT Content recording. A content recording saves content into a new file. Because the content must be new, the start time cannot be in the past.


[out]  Address of a variable that receives a pointer to the Recording object's IUnknown interface.

Return Values

Returns an HRESULT. Possible values include those in the following table.

Value Description
S_OK The method succeeded.


The Stream Buffer Sink filter's profile must be locked, either explicitly or implicitly, before you call this method. For more information, see IStreamBufferSink::LockProfile.

The returned IUnknown interface has an outstanding reference count. The caller must release the interface.


Include Sbe.h.
