Remarks

Gets value that indicates which streams the target format can have. The format to be used for the converted file. This includes the file format, any special settings used by that format, and which audio and/or video codec is to be used for the conversion, and any special settings used by the codecs.

Example

using Leadtools; 
using Leadtools.MediaFoundation; 
using LeadtoolsMediaFoundationExamples.Fixtures; 
 
 
public bool _result = false; 
public ConvertCtrlForm _form = new ConvertCtrlForm(); 
 
public void TargetFormatsExample() 
{ 
   // reference the convert control 
   ConvertCtrl convertctrl = _form.ConvertCtrl; 
 
   // input and output files 
   string inFile = Path.Combine(LEAD_VARS.MediaDir, "ConvertCtrl_Source.avi"); 
   string outFile = Path.Combine(LEAD_VARS.MediaDir, "ConvertCtrl_TargetFormatsExample.wmv"); 
 
   try 
   { 
      // set the video convert input file name 
      convertctrl.SourceFile = inFile; 
 
      // select video and audio target formats for the output 
      int index = -1; 
      TargetVideoFormats targetvideoformats = convertctrl.TargetFormats[convertctrl.TargetFormat].VideoFormats; 
      index = targetvideoformats.IndexOf("{33564D57-0000-0010-8000-00AA00389B71}/MP");// Windows Media Video 9 (WMV) Main Profile 
      targetvideoformats.Selection = index;

      targetaudioformats.Selection = index; 
 
      // select the WMV target format

      // set the result to what we expect 
      _result = (tft == TargetFormatType.WMV); 
 
      // set the target file 
      convertctrl.TargetFile = outFile; 
 
      // convert it now! 
      convertctrl.StartConvert(); 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
 
   // we'll loop on the state and pump messages for this example. 
   // but you should not need to if running from a Windows Forms application. 
   while (convertctrl.State == ConvertState.Running) 
      Application.DoEvents();
