在C＃中使用ffmpeg将两个mp4视频合并为单个视频不起作用

Question

For the last 4 hours I've been trying to combine 2 .mp4 files into one using ffmpeg in C#.

****My code is below:****

   public void MergeFiles(string strFile)
    {
        string strParam;

        string Path_FFMPEG = Server.MapPath("~/Video_Clips/ffmpeg.exe");

        //Merging two videos               
        String video1 = Server.MapPath("~/Videos/fast1.mp4");
        String video2 = Server.MapPath("~/Videos/fast2.mp4");
        String file = Server.MapPath("~/Videos/input.txt");
        String strResult =   Server.MapPath("~/Videos/ConvertedFiles/Output.mp4");

        strParam = " -f concat -i " + file + " -c copy " + strResult;

        process(Path_FFMPEG, strParam);
    }

   public void process(string Path_FFMPEG, string strParam)
    {
        try
        {
            Process ffmpeg = new Process();
            ProcessStartInfo ffmpeg_StartInfo = new ProcessStartInfo(Path_FFMPEG, strParam);
            ffmpeg_StartInfo.UseShellExecute = false;
            ffmpeg_StartInfo.RedirectStandardError = true;
            ffmpeg_StartInfo.RedirectStandardOutput = true;
            ffmpeg.StartInfo = ffmpeg_StartInfo;
            ffmpeg_StartInfo.CreateNoWindow = true;
            ffmpeg.EnableRaisingEvents = true;
            ffmpeg.Start();
            ffmpeg.WaitForExit(30000);
            //ffmpeg.WaitForExit();
            ffmpeg.Close();
            ffmpeg.Dispose();
            ffmpeg = null;
        }
        catch (Exception ex)
        {

        }
    }

My input.txt file is below:

file 'D:/Kapil_WorkSpace/ExtraProjectSource/VideoDemo/VideoDemo/Videos/fast1.mp4'

file 'D:/Kapil_WorkSpace/ExtraProjectSource/VideoDemo/VideoDemo/Videos/fast2.mp4'

Please help. Thanks in advance.

Answer 1

Finally, i found answer for my own question.

I have used ffmpeg.exe file and there is for 32 bit system and i am using 64 bit. So, problem is in ffmpeg build file. I have download new 64 bit build for that.

And another issue is path of videos in input.txt file are wrong.So, made it correctly and it's work completely. But it take too much time for some video and some video is work faster. I don't know what is reason for that.

Thanks all
