• nginx-rtmp : reverse proxy multiple streams into 1 output stream with gstreamer/FFMPEG

  16 décembre 2016, par JGM.io

  I am building an application where end-users can switch between live camera feeds.
  The goal is for the end-user to be able to record his/her own experience at will (client sends ’record’/’switch to stream#’ message to server) without interrupting the output RTMP stream or fragmenting the recorded file.

  The client would access( and record) this stream (for simplicity I left out the fallback video source if the udp src is not streaming) :

  gst-launch-1.0 udp://127.0.0.1:10000 ! config ! rtmp://TARGET_IP

  The idea is to have multiple internal commands standing by, activated by a client message. When the user switches to a feed the current running command is killed and the new command is launched. Because they all point to the same receiving end-point the end-user should not have to reconnect etc...

  gst-launch-1.0  ! config! udp://127.0.0.1:10000
  
  gst-launch-1.0  ! config ! udp://127.0.0.1:10000
  
  gst-launch-1.0  ! config ! udp://127.0.0.1:10000

  Can this be done from within nginx / nginx-rtmp or do I need to have an additional back-end logic running to do this ?

  The bonus question is how to do this with multiple users concurrently.

  NOTE : You could replace gst-launch-1.0 with FFMPEG. It’s just that I use GStreamer for my project

• C# redirect ffmpeg output to textbox in realtime

  21 mars 2018, par adrifcastr

  So I’ve been reading a lot through stackoverflow, and I found a lot of questions trying to deal with a similar problem as mine, but none of the solutions worked for me. So here is what I have :

  I have a WPF GUI application which launches ffmpeg by the following code :

          private void convertbutton_Click(object sender, RoutedEventArgs e)
  
      {
  
          string resdir = AppDomain.CurrentDomain.BaseDirectory + "\\res";
  
          Extract("ADC", AppDomain.CurrentDomain.BaseDirectory + "\\res", "res", "ffmpeg.exe");
  
  
  
          string ffdir = AppDomain.CurrentDomain.BaseDirectory + "\\res\\ffmpeg.exe";
  
          string arg = @"-progress progresslog.txt -y -activation_bytes ";
  
          string arg1 = @" -i ";
  
          string arg2 = @" -ab 80k -vn ";
  
          string abytes = bytebox.Text;
  
          string arguments = arg + abytes + arg1 + openFileDialog1.FileName + arg2 + saveFileDialog1.FileName;
  
  
  
          Process ffm = new Process();
  
          ffm.StartInfo.FileName = ffdir;
  
          ffm.StartInfo.Arguments = arguments;
  
          ffm.StartInfo.CreateNoWindow = true;
  
          ffm.StartInfo.RedirectStandardOutput = true;
  
          ffm.StartInfo.RedirectStandardError = true;
  
          ffm.StartInfo.UseShellExecute = false;
  
          ffm.StartInfo.WorkingDirectory = Directory.GetCurrentDirectory();
  
          ffm.Start();
  
          ffm.WaitForExit();
  
  
  
          ffm.Close();
  
  
  
          MessageBox.Show("Conversion Complete!");
  
  
  
          File.Delete("progresslog.txt");
  
          Directory.Delete(resdir, true);
  
      }

  So on this application I do also have other processes, which display their output to the textbox after finishing what they are doing, so but since ffmpeg outputs it’s conversion progress in the cmd output, I need to get exactly that being displayed in the textbox in realtime.

  And I am pretty sure that ffmpeg outputs into stderr same w/ ffprobe.

  I’d appreciate any help, since days of googleing didn’t help me with anything so far.
  Thanks in advance.
