如何将视频文件拆分为图像？

我正在尝试使用Aforge.Video.DirectShow从视频文件中捕获帧，但是当我到达此行时它无法正常工作

I am trying to capture frames from a video file using Aforge.Video.DirectShow but it doesn't work properly as when I reach on this line

filesource.NewFrame += filesource_NewFrame;

它给出了一个错误线程0x2094已退出代码259（0x103）。当我尝试stepinto

it gives me an error "The thread 0x2094 has exited with code 259 (0x103)." also when i try to stepinto

filesource_NewFrame 

时，它表示代码没有运行，而

it says code is not running whereas

filesource.IsRunning

为true且收到的帧数是$

is true and frames received are 0.

FileVideoSource filesource = new FileVideoSource();
filesource.Source = "C:\\Users\\Zam\\Videos\\akcent 1-cut.avi";
            Console.WriteLine("Start ");
            
            source.Start();
            int i=0;
            if (filesource.IsRunning)
            {
                Console.WriteLine("it is running and source is: "+source.Source);
                while (i <= filesource.FramesReceived)
                {
                    filesource.NewFrame += filesource_NewFrame;
                    Console.WriteLine("Start and execute ");
                    i++;
                }
            }
            else Console.WriteLine("File is not running");
        }

        void filesource_NewFrame(object sender, NewFrameEventArgs eventArgs)
        {
            mypic.Image = new Bitmap(eventArgs.Frame, 300, 300);
            Console.WriteLine("Working.....");
        }
