Example
using Leadtools;
using Leadtools.Multimedia;
using LeadtoolsMultimediaExamples.Fixtures;
public bool _result = false;
public ConvertCtrlForm _form = new ConvertCtrlForm();
// input and output file names
public string _inFile = Path.Combine(LEAD_VARS.MediaDir, "ConvertCtrl_Source.mpeg");
public string _outFile = Path.Combine(LEAD_VARS.MediaDir, "ConvertCtrl_SourceStreamExample.avi");
public void SourceStreamExample()
{
// reference the convert control
ConvertCtrl convertctrl = _form.ConvertCtrl;
try
{
// set the source stream
convertctrl.SourceStream = new StreamReader(_inFile).BaseStream;
// select video and audio compressors
convertctrl.VideoCompressors.Mpeg2.Selected = true;
convertctrl.AudioCompressors.AC3.Selected = true;
// set the target file and format
convertctrl.TargetStream = new MemoryStream();
convertctrl.TargetFormat = TargetFormatType.AVI;
// subscribe to the complete event to check our result
convertctrl.Complete += new EventHandler(ConvertCtrl_Complete);
// set the allowed streams
convertctrl.AllowedStreams = StreamFormatType.AudioVideoCC;
// convert it!
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.
