SetClosedCaptioningTargetFile Method

Summary

Sets the filename and options to save closed captioning data as SRT or TEXT format files.

Syntax

C++/CLI

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.

Remarks

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 https://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.

Example

using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public bool _result = false; 
public ConvertCtrlForm _form = new ConvertCtrlForm(); 
 
public void ClosedCaptioningTargetFile() 
{ 
   // reference the convert control 
   ConvertCtrl convertctrl = _form.ConvertCtrl; 
 
   // target file 
   string targetFileCc = Path.Combine(LEAD_VARS.MediaDir, "ConvertCtrl_ClosedCaptioningTargetFile.srt"); 
   ClosedCaptioningFlags flags = ClosedCaptioningFlags.Default; 
   string testFile; 
   ClosedCaptioningFlags testFlags; 
 
   try 
   { 
      // set target file name and save options 
      convertctrl.SetClosedCaptioningTargetFile(targetFileCc, flags); 
 
      convertctrl.GetClosedCaptioningTargetFile(out testFile, out testFlags); 
 
      if (testFile == targetFileCc && testFlags == flags) 
         _result = true; 
      else 
         _result = false; 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
}
