• Calling external applications from windows service [duplicate]

  3 novembre 2016, par vvj

  This question already has an answer here :

  • How can I run an EXE program from a Windows Service using C# ?
    
    5 answers
    

  I have a windows service as part of my project which has to communicate with external applications to process the files. One of the external application I am using is FFMPEG.exe.

  My problem is when I call FFmpeg or other applications as the new process. After starting the process, it is getting idle. it will neither get execute successfully nor get an exit.

  I am facing this problem with multiple external exe’s and it happens only while calling from the windows service. When I tried the same block of code from a windows forms application, it works perfectly. Below is the sample code I used. Could anyone tell me whats wrong with this.?

  Process FFMPEGProcess = new Process();
  
  FFMPEGProcess.StartInfo.FileName =@"ffmpeg.exe";                                   
  
  string strArgument = @" -i  \\MachineName\video\file.mp4 -y -s 176x132 -r 0.2 \\MachineName\Image\File%4d.jpg";
  
  FFMPEGProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
  
  FFMPEGProcess.StartInfo.CreateNoWindow = true;
  
  FFMPEGProcess.StartInfo.UseShellExecute = true;
  
  FFMPEGProcess.StartInfo.Arguments = strArgument;
  
  FFMPEGProcess.Start();            
  
  FFMPEGProcess.WaitForExit();

• Systemd service (python loop -> ffmpeg stream)

  7 janvier 2019, par Kevitto

  I am currently running a stream with ffmpeg, through icecast2 through a python snippet (Fig1). I have created a systemd service to run said python script on boot (Fig2) and use a custom target (Fig3) to make sure it loads once every other service is loaded, mostly for icecast2.

  I’ve conducted multiple tests, and the stream works fine if launched either from the python code or if I restart the service attached to it.

  My problem is, on a (re)boot of the system, the service runs for approximately 15 seconds, then the stream dies. I’ve read so much on python and systemd, but I can’t for the life of me figure out where the problem lies. I’ve tried changing my python code, the unit load order and anything else I found online that could help, but found nothing.

  import time
  
  import subprocess
  
  
  
  def start():
  
      return subprocess.Popen(r’ffpmeg -re -f alsa -ac2 -i hw:1,0 -acodec mp3 -ab 320k -f mp3 icecast://sourcehackme@localhost:8000/stream', shell=True)
  
  
  
  testProcess = start()
  
  
  
  while True:
  
  
  
      res = testProcess.poll()
  
      if res is not None:
  
          testProcess = start()
  
      time.sleep(1)
