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：
- 打开你的Visual Studio 项目
- 转到工具->NuGet包管理器->管理解决方案的NuGet包
- 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());
}
