C#+AForge 实现视频录制

​ 在C#中，使用AForge 库实现视频录制功能是一个比较直接的过程。AForge 是一个开源的.NET框架，提供了许多用于处理图像和视频的类库。

开发步骤

安装AForge库

​ 首先，确保你的项目中已经安装了 AForge.Video和AForge.Video.FFMPEG.你可以通过NuGet包管理器来实现安装这些库：

1. 打开你的Visual Studio 项目
2. 转到工具->NuGet包管理器->管理解决方案的NuGet包
3. 搜索并安装 AForge 和 AForge.Video 以及 AForge.Video.FFMPEG

打开与关闭摄像头

/// <summary>
/// 打开摄像头
/// </summary>
private void OpenCamera()
{//设置视频源并启动this.videoCaptureDevice = new VideoCaptureDevice(filterInfoCollection[this.comboBox1.SelectedIndex].MonikerString);this.videoSourcePlayer1.VideoSource = this.videoCaptureDevice;this.videoSourcePlayer1.Start();isOpen = true;this.btnOpen.Text = "关闭";
}/// <summary>
/// 关闭摄像头
/// </summary>
private void CloseCamera()
{if (this.videoSourcePlayer1.VideoSource != null){this.videoSourcePlayer1.SignalToStop();this.videoSourcePlayer1.WaitForStop();this.videoSourcePlayer1.VideoSource = null;isOpen = false;this.btnOpen.Text = "打开";}
}

实现拍照

/// <summary>
/// 拍照
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button2_Click(object sender, EventArgs e)
{if (!this.isOpen){MessageBox.Show("请先打开摄像头!", "提示", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);return;}try{//拍照bmp = this.videoSourcePlayer1.GetCurrentVideoFrame();this.pictureBox1.Image = bmp;if (!Directory.Exists("images"))Directory.CreateDirectory("images");string fileName = string.Format("images/图片_{0}.jpg", DateTime.Now.ToString("yyyy-MM-dd hh-mm-ss"));bmp.Save(fileName);}catch (Exception ex){MessageBox.Show(ex.Message, "错误", MessageBoxButtons.OK, MessageBoxIcon.Error);}
}

实现录像

/// <summary>
/// 开始录像
/// </summary>
private void StartRecord()
{if (!Directory.Exists("videos"))Directory.CreateDirectory("videos");string fileName = string.Format("videos/录像_{0}.avi", DateTime.Now.ToString("yyyy-MM-dd hh-mm-ss"));this.videoFileName = fileName;// 创建视频文件写入器videoWriter = new VideoFileWriter();videoSourcePlayer1.NewFrame += VideoSourcePlayer1_NewFrame;videoWriter.Open(fileName, 1280, 960, 30, VideoCodec.MPEG4, 1000000); // 设置分辨率、帧率和比特率
}/// <summary>
/// 停止录像
/// </summary>
private void StopRecord()
{this.CloseCamera();if (videoWriter != null){videoWriter.Close();videoWriter = null;}this.FlushVideoPlayList();
}

实现录屏

/// <summary>
/// 开始录屏
/// </summary>
/// <param name="path"></param>
public void StartRecording(string path) //该方法需要有一个路径参数，前面我们设置过了
{var directory = Path.GetDirectoryName(path);if (!Directory.Exists(directory)) //检查路径是否存在，不存在就自动创建{Directory.CreateDirectory(directory);}try{FrmMain.videoWriter = new VideoFileWriter();//用于生成视频文件，参数分别为路径、视频的宽度、高度、帧数、编码格式以及视频码率FrmMain.videoWriter.Open(path, Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, 25, VideoCodec.MPEG4, 5000000);recordingThread = new Thread(RecordScreen);recordingThread.Start();}catch (Exception err){Console.WriteLine(err.ToString());MessageBox.Show("屏幕录制开启失败: " + err.Message, "提示！");}
}/// <summary>
/// 停止录屏
/// </summary>
public void StopRecording()
{try{recordingThread.Join();FrmMain.videoWriter.Close();}catch (Exception err){MessageBox.Show("屏幕录制停止失败: " + err.Message, "提示！");Console.WriteLine(err.ToString());}
}

视频播放

/// <summary>
/// 双击视频列表
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void listBox1_MouseDoubleClick(object sender, MouseEventArgs e)
{if (this.listBox1.SelectedItem == null) return;this.axWindowsMediaPlayer1.URL = string.Format("videos/{0}", this.listBox1.SelectedItem.ToString());
}

object sender, MouseEventArgs e)
{
if (this.listBox1.SelectedItem == null) return;

this.axWindowsMediaPlayer1.URL = string.Format("videos/{0}", this.listBox1.SelectedItem.ToString());

}
