ffmpeg does not exit when pipe is closed ?
9 juin 2024, par ThomasIf this has already been brought up, I apologize. This is part of a software tuner package I am writing as a POC. It is used by Plex Media Server. For the most part, it works with good picture quality but leaves ffmpeg processes when the User clicks "Stop" or closes the browser, I assume plex is closing the socket and that ffmpeg is not erroring out, but I am not sure. this is part of a function where I pass in a TCP Client Network Stream.


TCPListener waits for a call, when it accepts one, it passes the network stream off to this function below. When the TCP Client disconnects, ffmpeg never exits, waitforexit never returns.


ffmpeg args :


-hide_banner -loglevel error -i {0} -c copy -f mpegts pipe:1



c#


string Arguments = string.Format(ffmpegStreamOptions, URL,Overlay);
 Process p = new Process();
 p.StartInfo.UseShellExecute = false;
 p.StartInfo.RedirectStandardOutput = true;
 p.StartInfo.RedirectStandardError = true;
 p.StartInfo.CreateNoWindow = true;
 p.StartInfo.FileName = "ffmpeg.exe"; // Replace with your executable path
 p.StartInfo.Arguments = Arguments;
 
 p.Start();
 var errorMemoryStream = new MemoryStream();
 var programTask = Task.WhenAny(
 p.StandardOutput.BaseStream.CopyToAsync(client_stream



),
p.StandardError.BaseStream.CopyToAsync(errorMemoryStream)
) ;


p.WaitForExit(); //stuck here after the connection is broken and never exits.



Any help would be appreciated
Thanks !
