• How to stop ffmpeg process after it has finished processing in C# ?

  7 janvier 2018, par alan samuel

  I am trying to stop the ffmpeg process once it has finished doing what I want it do, but I am not able to find a way.

  Here is what I have done.

  //Process for running ffmpeg
  
  Process process = new Process();
  
  process.StartInfo.RedirectStandardOutput = true;
  
  process.StartInfo.RedirectStandardError = true;
  
  process.StartInfo.FileName = ffmpegfile;
  
  process.StartInfo.Arguments = commandtorun;
  
  process.StartInfo.UseShellExecute = false;
  
  process.StartInfo.CreateNoWindow = true;
  
  
  
  
  
  process.Start();
  
  process.WaitForExit();
  
  
  
  process.Close();

  The problem is ffmpeg does not tell the process to stop after it has finished executing, so I cant use WaitForExit() call.

  What i tried doing is

  commandtorun = commandtorun+ " && exit";

  to force ffmpeg to close after it finishes executing. Now this works when I try in cmd.

  But when I do the same thing in C#, ffmpeg closes down as soon as the command is executed.

  Is there any way to force ffmpeg or the process to close after the processing is done ?

• ffmpeg how to mix 2 RTP streams that individually start and stop randomly ?

  13 novembre 2020, par JMain

  I want to do this :

  


  ffmpeg listens to 2 incoming rtp streams, and continuously send those mixed together to a single outgoing rtp stream

  


  However, the 2 incoming streams are going to be starting and stopping randomly and independently of each other, as they have audio. They don't send audio silence, they stop sending when there is silence and then they start sending again when there is audio. ffmpeg seems to error on this situation.

  


  I have this :
ffmpeg -i rtp ://0.0.0.0:11000 -i rtp ://0.0.0.0:12000 -filter_complex amix -f rtp rtp ://10.10.10.10:13000

  


  This is what happens with ffmpeg :
It wait for the audio to start, and then it sends to the output. But, when the input stop sending, I get this error :
rtp ://0.0.0.0:11000 Unknown error
rtp ://0.0.0.0:12000 Unknown error

  


  and it crashes.

  


  How can I keep it active even when one or the other input isn't sending, and how can I prevent it from crashing ?

  


  If ffmpeg outputs silence all the time when it doesn't receive anything, that would be acceptable too.
