废话就不说了直接上手，展示图如下：
1.引用AForge组件,
nuget 方式 引用如下组件
视频写入引入
偷懒的话 可以将debug下的aforge组件复制过去引用，部分代码如下：
private void Form1_Load(object sender, EventArgs e) { GraphicsPath gp = new GraphicsPath(); Rectangle rectg = new Rectangle( new Point( this.GbxVideo.Location.X, this.GbxVideo.Location.Y), new Size(GbxVideo.Width-50, GbxVideo.Height-50)); gp.AddEllipse(rectg); GbxVideo.Region = new Region(gp);
videoDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice); if (videoDevices.Count == 0) { MessageBox.Show("请连接视频!","提示", MessageBoxButtons.OK, MessageBoxIcon.Warning); return; } if (videoDevices.Count > 0) {

}
private void btnexit_Click(object sender, EventArgs e) { if (videoSourcePlayer1.IsRunning) { MessageBox.Show("请先停止录制视频","提示", MessageBoxButtons.OK, MessageBoxIcon.Error); return; } this.Dispose();
