• Process stalls when launched in .NET (ffmpeg)

  13 octobre 2016, par Rhys Causey

  I’m trying to launch ffmpeg as a Process in .NET (C#), but in some cases, depending on the arguments (specifically, if I omit video arguments in order to create an audio file), it’s stalling. It launches, outputs some lines, but then just stalls (using 0% CPU). When the parent .NET process is killed, it continues, and if I let it continue, ffmpeg produces the file correctly. I thought it might be due to using Peek() to look at the stream, so I just simplified it to the following, which behaves the same :

  _process = new Process
  
  {
  
      StartInfo =
  
      {
  
          UseShellExecute = false,
  
          RedirectStandardOutput = false,
  
          RedirectStandardError = true,
  
          FileName = "c:\\ffmpeg.exe",
  
          Arguments = string.Format(
  
      "-i {0} {1} {2} {3} -y {4}", inputPath, videoArgs, audioArgs, options, outputPath)
  
      }
  
  };
  
  _process.Start();
  
  _process.WaitForExit();

  ffmpeg gets to the point where it outputs information about the input video/audio streams before stalling. Executing the command via the command prompt works as expected.

  Does anyone know what the problem could be ?

  Edit :

  Just to add, I tried UseShellExecute = true (and RedirectStandardError = false), and this works. I still need to read the output, however, so this doesn’t really help me.

• ffmpeg.exe freezes

  17 mars 2015, par Ayhan Dorman

  I’m using Asp.Net C# Framework 4 and currently developing a video conversion application. I’m also using ffmpeg to convert from all uploaded formats to flv. I’m first converting uploaded file to mpg and after to flv due to problems I encountered while trying conversion directly to flv from mp4 sometimes. But ffmpeg freezes as soon as it’s done with conversion process to mpg file. When I run task manager and check the processes list, it just stands there using no CPU resource. When I end the ffmpeg process directly from task manager, other process take place which converts from mpg to flv and preview file (jpg) and works smoothly. Due to freezing of first process, the second process cannot start when I try to upload from my web page’s file upload form. I appreciate any response from now. Here is my code :

          string duration = "00:00:00";
  
  
  
          //converting video
  
          Process ffmpeg;
  
          ffmpeg = new Process();
  
  
  
          // convert to mpg 1st
  
          ffmpeg.StartInfo.Arguments = " -i \"" + Server.MapPath("static/user/vid/") + videolink + "\" -f mpeg -b 300k -ac 2 -ab 128k -ar 44K \"" + Server.MapPath("static/user/vid/") + mpglink + "\"";
  
          ffmpeg.StartInfo.FileName = Page.MapPath("bin/ffmpeg.exe");
  
          ffmpeg.StartInfo.CreateNoWindow = true;
  
          ffmpeg.StartInfo.UseShellExecute = false;
  
          ffmpeg.StartInfo.RedirectStandardOutput = true;
  
          ffmpeg.StartInfo.RedirectStandardError = true;
  
          ffmpeg.Start();
  
  
  
          ffmpeg.WaitForExit();
  
          ffmpeg.Close();
  
  
  
  
  
          // mpg 2 flv
  
          ffmpeg = new Process();
  
          ffmpeg.StartInfo.Arguments = " -i \"" + Server.MapPath("static/user/vid/") + mpglink + "\" -f flv -s 624x352 \"" + Server.MapPath("static/user/vid/") + flvlink + "\"";
  
          ffmpeg.StartInfo.FileName = Page.MapPath("bin/ffmpeg.exe");
  
          ffmpeg.StartInfo.CreateNoWindow = true;
  
          ffmpeg.StartInfo.UseShellExecute = false;
  
          ffmpeg.StartInfo.RedirectStandardOutput = true;
  
          ffmpeg.StartInfo.RedirectStandardError = true;
  
          ffmpeg.Start();
  
  
  
          ffmpeg.BeginOutputReadLine();
  
          string error = ffmpeg.StandardError.ReadToEnd();
  
          ffmpeg.WaitForExit();
  
  
  
          try
  
          {
  
              duration = error.Substring(error.IndexOf("Duration: ") + 10, 8);
  
          }
  
          catch
  
          {
  
          }
  
  
  
          if (ffmpeg.ExitCode != 0)
  
          {
  
              ltrUpload.Text = "<div class="\&quot;resultbox-negative\&quot;">Problem occured during upload process. Error code: " + error + "<br />" + "</div>";
  
              return;
  
          }
  
          ffmpeg.Close();
  
  
  
  
  
          // generate preview image
  
          ffmpeg.StartInfo.Arguments = " -i \"" + Server.MapPath("static/user/vid/") + flvlink + "\" -s 624x352 -ss 00:00:03 -an -vframes 1 -f image2 -vcodec mjpeg \"" + Server.MapPath("static/user/vid/") + flvlink.Replace(".flv", ".jpg") + "\"";
  
          ffmpeg.StartInfo.FileName = Page.MapPath("bin/ffmpeg.exe");
  
          ffmpeg.StartInfo.CreateNoWindow = true;
  
          ffmpeg.StartInfo.UseShellExecute = false;
  
          ffmpeg.StartInfo.RedirectStandardOutput = true;
  
          ffmpeg.StartInfo.RedirectStandardError = true;
  
          ffmpeg.Start();
  
          ffmpeg.WaitForExit();
  
          ffmpeg.Close();
  
  
  
          // deleting original file and mpg
  
          FileInfo fi = new FileInfo(Server.MapPath("static/user/vid/") + videolink);
  
          if (fi.Exists) fi.Delete();
  
          fi = new FileInfo(Server.MapPath("static/user/vid/") + mpglink);
  
          if (fi.Exists) fi.Delete();
