Question

如何在C＃中从流图像（只有没有声音的图像）构建视频？

以下是我的应用程序的一些代码：

static int ii = 1;
public void drawBitmap(byte[] data)
{
    MemoryStream ms = new MemoryStream(data);
    try
    {
        Bitmap b = new Bitmap(ms);
        b.Save(@"c:\test\" + (ii++) + ".jpg");
        Image i = (Image)b;
        pictureBox1.Image = i;
        ii++;
    }
    catch (Exception e)
    {
    }
}

Answer 2

我使用了上面提到的包装器，如下所示：

private static void hejHopp()
{
    //http://www.codeproject.com/Articles/7388/A-Simple-C-Wrapper-for-the-AviFile-Library

    //myReadyNAS device, got files via FTP from my webcam
    var jpgFileList = Directory.EnumerateFiles(sourcePath,"*.jpg");

    //load the first image
    Bitmap bitmap = (Bitmap)Image.FromFile(jpgFileList.First());

    //create a new AVI file
    AviManager aviManager = new AviManager(sourcePath + "\\tada.avi", false);

    //add a new video stream and one frame to the new file
    //set IsCompressed = false
    VideoStream aviStream =  aviManager.AddVideoStream(false, 2, bitmap);

    jpgFileList.Skip(1).ToList().ForEach(file =>
    {
        bitmap = (Bitmap)Bitmap.FromFile(file);
        aviStream.AddFrame(bitmap);
        bitmap.Dispose();
    });

    aviManager.Close();
}
