c# 摄像头及保存视频记录

using System.IO;
        using ICameraDll.DirectX.Capture;
 
        Capture capture;    //摄像头录像操作
        Filters filters = new Filters();    //Filter集合
 
        // 函数
        int GetffshowIndex()
        {
            FilterCollection videoCompressors = this.filters.VideoCompressors;
            for (var i = 0; i < videoCompressors.Count; i++)
            {
                if ((videoCompressors[i] != null) && videoCompressors[i].Name.Equals("ffdshow video encoder"))
                {
                    return i;
                }
            }
            return -1;
        }
        void CreateFilepath(string FilePath)
        {
            var dir = FilePath.Remove(FilePath.LastIndexOf("\\"));
            if (!Directory.Exists(dir))
            {
                Directory.CreateDirectory(dir);
            }
        }
        
        private void button1_Click(object sender, EventArgs e)
        {
            Control videoControl = pictureBox1;
            string filePath = "d:\\Camera\\test\\Video\\";
            string fileName = "test.avi";
 
            // 检测摄像头是否被占用
            if (capture != null)
            {
                capture.Stop();
                capture.DisposeCapture();
            }
 
            //获取ffshow视频解码器索引
            var ffshowIndex = GetffshowIndex();
 
            if (ffshowIndex > 0)
            {
                var Flie = filePath + fileName;
                CreateFilepath(Flie);
                capture = new Capture(new Filters().VideoInputDevices[0], null);
 
                //设置承载控件
                capture.PreviewWindow = videoControl;
 
                //设置视频解码器
                capture.VideoCompressor = filters.VideoCompressors[ffshowIndex];
 
                //设置要保存的文件路径和文件名
                capture.Filename = Flie;
 
                //设置帧
                capture.FrameRate = 15;
 
                //设置视频分辨率
                capture.FrameSize = new Size(320, 240);
 
                //开启录制
                capture.Start();
            }
 
 
        }
 
        private void button2_Click(object sender, EventArgs e)
        {
            if (capture != null)
            {
                // 停止录制
                capture.Stop();
                capture.DisposeCapture();
                capture = null;
            }
        }

 另外运行这个代码可能需要给电脑安装视频解码器， 用的是 codecs_pack 这款软件。
