• Anomalie #4214 (Rejeté) : Notices sous easyphp et php 7.3 rc3

  2 novembre 2018, par Franck D

  Sous easyphp avec php 7.3rc3 avec un spip 24140 tout neuf, j’ai donc aussi le commit https://zone.spip.net/trac/spip-zone/changeset/112276/spip-zone (qui n’a sans doute rien avoir avec le problème)
  A savoir que pour les tests, je fais l’ajout d’un fichier mes_options contenant :

  Télécharger

  J’ai un warning qui s’affiche, mais pour le voir, j’ai installer manuellement le plugin https://plugins.spip.net/simplog.html dans le dossier "plugins"
  Puis après avoir fait l’ajout du dépôt de la zone, je vais à la page /ecrire/ ?exec=charger_plugin et je clique sur le bouton "Rechercher" de la boite "Rechercher et ajouter des plugins"

  Pour info, sinon, cela semble quand même fonctionner normalement :-)

• How Read .mp4 video and then put it in NamedPipeServerStream ?

  23 mars 2019, par Oleg Pi

  How I Might Put .mp4 readed with StreamReader and then put it into pipe ?
  I need to read the data and send it to the pipe. I read the .mpg4 file. Then I process it through ffmpeg. Am I trying to send the file to the pipe correctly ?

  public void getVideoFramesFromLocalPath(string fileName, string outputFileName, int period)
  
      {
  
          Thread th1 = new Thread(new ParameterizedThreadStart(PipeLine));
  
          th1.Start(fileName);            
  
  
  
          int bitrate = 5000;
  
          int fps = 10;
  
  
  
          string strTakeFrame = $"-f image2pipe -i pipe:videoPipe -qscale:v 4 -vf fps=1/{period} {outputFileName}_%04d.jpg";       
  
  
  
          ffProcessStart(strTakeFrame);
  
      }
  
  
  
      private async void PipeLine(object fileName)
  
      {
  
          StreamReader SR = new StreamReader((string)fileName);
  
          NamedPipeServerStream pipeServer = new NamedPipeServerStream("videoPipe", PipeDirection.Out);
  
          pipeServer.WaitForConnection();
  
          StreamWriter SW = new StreamWriter(pipeServer);
  
          SW.Write(SR.ReadToEnd());
  
          SW.Flush();
  
      }
  
      static void ffProcessStart(string commandLine)
  
      {
  
          ProcessStartInfo startInfo = new ProcessStartInfo();            
  
  
  
          startInfo.CreateNoWindow = false;                                
  
  
  
          startInfo.UseShellExecute = false;                              
  
  
  
          startInfo.FileName = @"ffmpeg.exe";                             
  
  
  
          startInfo.WindowStyle = ProcessWindowStyle.Hidden;              
  
  
  
          startInfo.Arguments = commandLine;                              
  
  
  
          try
  
          {
  
              using (Process exeProcess = Process.Start(startInfo))       
  
              {
  
                  exeProcess.WaitForExit();

• ffmpeg posting to nginx hangs after 90 minutes

  22 octobre 2018, par Harnek Gulati

  I’m using a very simple program to push an ffmpeg stream from my raspberry pi camera to a nginx server. However, it fails after 90 minutes, with almost every single Raspberry Pi I use (I have this code on 12 Raspberry Pis).
  Here is my ffmpeg command :

  raspivid -o - -t 0 -w 640 -h 480 -fps 25 | ffmpeg -re -i - -vcodec copy -hls_time 4 -f hls -hls_list_size 5 -hls_wrap 5 -threads 0  -timeout 5000 -max_reload 20000 -method PUT http://{}:{}/live/{}

  And here is my configuration for nginx.conf :

  #user nobody;
  
  load_module /usr/lib/nginx/modules/ndk_http_module.so;
  
  load_module /usr/lib/nginx/modules/ngx_http_lua_module.so;
  
  
  
  worker_processes auto;
  
  env CONTROL_SERVER_IP;
  
  
  
  
  
  #error_log /var/log/nginx/error.log;
  
  error_log /dev/stdout info;
  
  events {
  
      worker_connections 1024;
  
  }
  
  
  
  http {
  
      include     mime.types;
  
      default_type    application/octet-stream;
  
      access_log /dev/stdout;
  
      sendfile on;
  
      keepalive_requests 100000;
  
      keepalive_timeout 30;
  
  
  
    client_max_body_size 10M;
  
    server {
  
      listen 80;
  
      server_name localhost;
  
  
  
      location /live {
  
        root /var/static;
  
              client_body_temp_path   /var/static/client_temp;
  
  
  
              dav_methods PUT;
  
              create_full_put_path on;
  
              dav_access user:rw  group:r     all:r;
  
  
  
              types {
  
                  application/vnd.apple.mpegurl m3u8;
  
              }
  
  
  
              # Disable Cache
  
              add_header Cache-Control no-cache;
  
              include cors.conf;
  
    }
  
    }
  
  }
  
  
  
  daemon off;

  If anyone can help me, I would deeply appreciate it. I’ve been pulling my hair out trying to figure out this bug. On the raspberry pi, it hangs on this :

  And on the nginx logs, I get :

  192.168.10.242 - - [21/Oct/2018:22:34:01 +0000] "PUT /live/c35d8935-0a31-4d22-b71a-ad3f4f1d4763.m3u8 HTTP/1.1" 204 0 "-" "Lavf/57.83.100"

  I need to set up a way to either a) keep consistent connections longer than 90 minutes or b) detect when the 408 error happens and stop it from hanging.
