Remarks

You can use this method to retrieve the source plug-ins when you are using HTML as a source (as shown in the following example), or when controlling a digital device. 

Example Code

using WMEncoderLib;

try
{
// Create a WMEncoder object.
  WMEncoder Encoder;
  Encoder = new WMEncoder();

// Retrieve the source group collection and add a source group.
  IWMEncSourceGroupCollection SrcGrpColl;
  IWMEncSourceGroup SrcGrp;
  SrcGrpColl = Encoder.SourceGroupCollection;
  SrcGrp = SrcGrpColl.Add("SG_1");

// Add an audio, video, and HTML source. 
  IWMEncSource SrcAud;
  IWMEncVideoSource SrcVid;
  IWMEncSource SrcHTML;
  SrcAud = SrcGrp.AddSource(WMENC_SOURCE_TYPE.WMENC_AUDIO);
  SrcVid = (IWMEncVideoSource)SrcGrp.AddSource(WMENC_SOURCE_TYPE.WMENC_VIDEO);
  SrcHTML = SrcGrp.AddSource(WMENC_SOURCE_TYPE.WMENC_FILETRANSFER);

// Use the default audio and video devices. 
  SrcAud.SetInput("Default_Audio_Device", "Device", "");
  SrcVid.SetInput("Default_Video_Device", "Device", "");

// The HTML scheme is FileTransfer, and the resource string is not used. 
  SrcHTML.SetInput("Placeholdertext", "FileTransfer", "");

// Set the HTML stream to repeat. 
  SrcHTML.Repeat = true;

// Continue configuring the encoding session, including the profile and
// and broadcast settings.

// Start encoding. 
  Encoder.Start();

// Retrieve the file transfer plug-in from the HTML source. 
  object pUnkFileSrcPlugin;
  pUnkFileSrcPlugin = SrcHTML.GetSourcePlugin();
  IWMEncFileTransferSource FileTransSrc;
  object FileTransSrc = (IWMEncFileTransferSource)pUnkFileSrcPlugin;;

// Create a file set, add HTML content, and then send it. 
  IWMEncFileSet FileSet;
  FileSet = FileTransSrc.Add();
  FileSet.Add("C:\\HTML\\image.jpg", "https://YourWebSite/image.jpg");
  FileTransSrc.Send(FileSet);
}
