public class CMDRunHelper

     public static void RunCmdOnce(string batPath,string command)

Captura操作

需要准备以下文件(可参考上一节内容)

captura-cli.exe

ffmpeg.exe

public class CapturaHelper
 {
  private static string _basePath = $@"E:\Luncher\viedo";
  private static string _baseSavePath = @$"D:\Video\{DateTime.Now.ToString("yyyy-MM-dd")}";

 /// <summary>
    /// 开始录屏
    /// </summary>
    public static void StartCaptura()
    {
        //ShutdownCaptura();
        _fileName = Guid.NewGuid().ToString().Substring(0, 4);
        if (!Directory.Exists(_baseSavePath))
        { 
            Directory.CreateDirectory(_baseSavePath);
        }

        string baseFile = $"{Guid.NewGuid().ToString()}.mp4";
        string command = @$"captura-cli start  --cursor --keys --clicks  --delay=1000 --source screen:0 -f {_baseSavePath}\{baseFile} -y";
        CMDTools.CMDRunHelper.RunCmdOnce(_basePath,command);

    }
     /// <summary>
    /// 关闭录屏
    /// </summary>
    public static void ShutdownCaptura()
    {
        CMDTools.CMDRunHelper.InputCommand("q");
        CMDTools.CMDRunHelper.RunCmd("taskkill /f /t /im captura-cli.exe");
    }
     
 }
