• Console windows displayed during python script execution [closed]

  15 janvier 2020, par vivitare

  i’m trying to create a Youtube converter with python and Tkinter.
  The problem is during the conversion with ffmpeg encoder, a console appear. But I don’t want to display her.

  Windows console displayed during encoding with ffmpeg

  Is there a parameter or something like that to disable this console ?

  I’m using this code to launch dowlnoad and youtube-dl do the rest :

  ydl_opts = {
  
      'format': 'bestaudio/best',
  
      'postprocessors': [{
  
          'key': 'FFmpegExtractAudio',
  
          'preferredcodec': 'mp3',
  
          'preferredquality': '192',
  
      }],
  
      'logger': MyLogger(),
  
      'progress_hooks': [my_hook],
  
  }
  
  with youtube_dl.YoutubeDL(ydl_opts) as ydl:
  
      ydl.download(['https://www.youtube.com/watch?v=BaW_jenozKc'])

• 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: {

                      ping_timeout: 30
  
                  },
  
                  http: {
  
                      port: config.get('media_server.port'),

                      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
  
              }
