SetClosedCaptioningTargetFile Method

C++/CLI

'Declaration
 
Public Overridable Sub SetClosedCaptioningTargetFile( _
   ByVal FileName As String, _
   ByVal Flags As ClosedCaptioningFlags _
)

'Usage
 
Dim instance As ConvertCtrl
Dim FileName As String
Dim Flags As ClosedCaptioningFlags
 
instance.SetClosedCaptioningTargetFile(FileName, Flags)

public virtual void SetClosedCaptioningTargetFile( 
   string FileName,
   ClosedCaptioningFlags Flags
)

public:
virtual void SetClosedCaptioningTargetFile( 
   String^ FileName,
   ClosedCaptioningFlags Flags
)

Parameters

FileName: A character string that contains the filename to save the closed captioning data.
Flags: Value that represents the desired save options. For a list of possible values, refer to ClosedCaptioningFlags enumeration values.

Use this method to save the decoded closed captioning data coming from a LEAD MPEG2 decoder. Closed captioning data can be embedded inside MPEG2 Video Elementary stream. If so, then the convert object can decode this data and write it to SRT format using this method, where the closed captioning text and time are saved. For more information, refer to http://en.wikipedia.org/wiki/SubRip. Also, the convert object can save the closed captioning data as text.

By default this method saves the data as an SRT file; but if ClosedCaptioningFlags.Text is specified, the output will be a pure text file.
