C# 调用FFmpeg 根据图片合成视频

1.项目结构:

2.代码:

　　

using System;

using System.Collections.Generic;

using System.Diagnostics;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

namespace WebFFmpeg

{

    public partial class _Default : System.Web.UI.Page

    {

        protected void Page_Load(object sender, EventArgs e)

        {

        }

        protected void Button1_Click(object sender, EventArgs e)

        {

            string pathString = AppDomain.CurrentDomain.SetupInformation.ApplicationBase;

            Process p = new Process();

            p.StartInfo.FileName = pathString + "\\FFmpeg\\ffmpeg.exe";

            p.StartInfo.Arguments = @"-y -r 1 -i " +

                                    pathString + @"FFmpeg\pic\img%2d.jpg -i " +

                                    pathString + @"FFmpeg\music\02.mp3 -s 800x800 -vcodec mpeg4" +

                                    pathString + @"FFmpeg\vedio\out.mp4";

            p.StartInfo.UseShellExecute = false;

            p.StartInfo.RedirectStandardError = true;

            p.StartInfo.Crea teNoWindow = true;

            p.ErrorDataReceived += new DataReceivedEventHandler((s, message) => { Response.Write(message.Data); });//外部程序(这里是FFMPEG)输出流时候产生的事件,这里是把流的处理过程转移到下面的方法中,详细请查阅MSDN

            p.Start();//启动线程

            p.BeginErrorReadLine();//开始异步读取

            p.WaitForExit();//阻塞等待进程结束

            p.Close();//关闭进程

            p.Dispose();//释放资源

            Response.Write("<a href='FFmpeg/vedio/out.mp4'>下载</a>");

        }

    }

}
