jpeg to video(mpeg, avi) conversion

You can convert all your images to a video programatically by leveraging the ConvertCtrl class. Here is a snippet of code that highlights this based on the below tutorial:

static void Generate() 
{ 
    // Create sample source object 
    SampleSource smpsrc = new SampleSource(); 
 
    ConvertCtrl convertCtrl = new ConvertCtrl(true); 
 
    // Create a new media type wrapper 
    MediaType mt = new MediaType(); 
 
    string sourceDirectory = @"C:\LEADTOOLS22\Resources\Images"; 
    string outputFile = @"C:\LEADTOOLS22\Resources\Images\Video-Result.avi"; 
 
    double fps = 5.0; //frames per second 
    Bitmap bmp = new Bitmap(800, 600, PixelFormat.Format24bppRgb); 
    double AvgTimePerFrame = (10000000 / fps); 
 
    string[] files = Directory.GetFiles(sourceDirectory, "*.jpg"); 
 
    // Set the type to 24-bit RGB video 
    mt.Type = Constants.MEDIATYPE_Video; 
    mt.SubType = Constants.MEDIASUBTYPE_RGB24; 
 
    // Set the format 
    mt.FormatType = Constants.FORMAT_VideoInfo; 
 
    VideoInfoHeader vih = new VideoInfoHeader(); 
    int bmpSize = GetBitmapSize(bmp); 
 
    // Setup the video info header 
    vih.bmiHeader.biCompression = 0; // BI_RGB 
    vih.bmiHeader.biBitCount = 24; 
    vih.bmiHeader.biWidth = 800; 
    vih.bmiHeader.biHeight = 600; 
    vih.bmiHeader.biPlanes = 1; 
    vih.bmiHeader.biSizeImage = bmpSize; 
    vih.bmiHeader.biClrImportant = 0; 
    vih.AvgTimePerFrame.lowpart = (int)AvgTimePerFrame; 
    vih.dwBitRate = (int)(bmpSize * 8 * fps); 
 
    mt.SetVideoFormatData(vih, null, 0); 
 
    // Set fixed size samples matching the bitmap size 
    mt.SampleSize = bmpSize; 
    mt.FixedSizeSamples = true; 
 
    // Assign the source media type 
    smpsrc.SetMediaType(mt); 
 
    // Do NOT set a compressor convertCtrl.VideoCompressors.MCmpMJpeg.Selected = true; 
    // Assign the converter source 
    convertCtrl.SourceObject = smpsrc; 
    // Set the output file name 
    convertCtrl.TargetFile = outputFile; 
 
    convertCtrl.TargetFormat = TargetFormatType.AVI; 
 
    convertCtrl.StartConvert(); 
}
