• prevent ffmpeg from opening console window

  10 février 2020, par Yesub

  I have a node/express server which is used to give streams from IP camera to a website. Everything is working well. I run that webserver with PM2 on a windows server.

  The problem : for each stream I have a windows console opening with just nothing logged in. The console reopen when I try to close it.

  Is there a way to prevent those console to open ?

  Here is the related node.js code :

  const { NodeMediaServer } = require('node-media-server');
  
  
  
  private _initiate_streams(): void{
  
      DatabaseProvider.instance.camerasDao.getCamerasList().pipe(
  
        take(1)
  
      ).subscribe(
  
          (databaseReadOperationResult: DatabaseReadOperationResult) => {
  
              if (databaseReadOperationResult.successful === true){
  
                const cameras = databaseReadOperationResult.result;
  
                const tasks = [];
  
                cameras.forEach( camera => {
  
                  tasks.push(
  
                    {
  
                      app : config.get('media_server.app_name'),
  
                      mode: 'static',
  
                      edge: camera.rtsp_url,
  
                      name: camera.stream_name,
  
                      rtsp_transport: 'tcp'
  
                    }
  
                  )
  
                });
  
  
  
                const configMediaServer = {
  
                  logType: 3, // 3 - Log everything (debug)
  
                  rtmp: {
  
                      port: 1935,
  
                      chunk_size: 60000,
  
                      gop_cache: true,
  
                      ping: 60,
  
                      ping_timeout: 30
  
                  },
  
                  http: {
  
                      port: config.get('media_server.port'),
  
                      allow_origin: '*'
  
                  },
  
                  auth: {
  
                      play: true,
  
                      api: true,
  
                      publish: true,
  
                      secret: config.get('salt'),
  
                      api_user: 'user',
  
                      api_pass: 'password',
  
                  },
  
                  relay: {
  
                      ffmpeg: 'C:\\FFmpeg\\bin\\ffmpeg.exe',
  
                      tasks: tasks
  
                  }
  
                };
  
  
  
                var nms = new NodeMediaServer(configMediaServer)
  
                nms.run();
  
              } else {
  
                  // catch exception
  
              }
  
          }
  
      );
  
    }

• Cannot access the file because it is being used by another process using ffmpeg

  17 avril 2015, par Andrew Simpson

  I am getting the error :

  Cannot access the file because it is being used by another process

  I have a C# desktop app.

  I am using the Process class to convert images to a video file by using FFMPEG.

  This is my code :

  using (Process serverBuild = new Process())
  
  {
  
      serverBuild.StartInfo.WorkingDirectory = Environment.CurrentDirectory;
  
      string args = " -f image2  -i " + {path} + "\\img%05d.jpg -s 352x288  -filter:v \"setpts=5.0*PTS\" -y " + {path}\\File.mp4;
  
  
  
      serverBuild.StartInfo.Arguments = args;
  
      serverBuild.StartInfo.FileName = "ffmpeg.exe";
  
      serverBuild.StartInfo.UseShellExecute = false;
  
      serverBuild.StartInfo.RedirectStandardOutput = true;
  
      serverBuild.StartInfo.RedirectStandardError = true;
  
      serverBuild.StartInfo.CreateNoWindow = true;
  
      serverBuild.Start();
  
      //  string output = serverBuild.StandardOutput.ReadToEnd();
  
      //Log.Instance.Debug(serverBuild.StandardError.ReadToEnd());
  
      serverBuild.WaitForExit();
  
      serverBuild.Close();
  
  
  
  }
  
  
  
   Directory.Delete(ExportRoute + FFMPEGPacket.LicenseKey + "\\" + FFMPEGPacket.Guid, true);
  
  
  
  //which raise the error..

  The images are all deleted but the File.Mp4 is not and that is the error. The error says that the newly created MP4 file cannot be deleted.

  NB
  This is partial code to illustrate the error
