IStreamBufferSink::CreateRecorder

This topic applies only to Windows XP Service Pack 1 or later.

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

Syntax

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

Parameters

pszFilename

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

dwType

[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.

pRecordingIUnknown

[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.

Remarks

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.

Requirements

Header: Include Sbe.h.
