• Anomalie #3413 : Un script s’affiche lorsqu’on prévisualise un commentaire et que $filtrer_javascr...

  22 octobre 2015, par - Equipement

  Bonjour,
  Si dans le fichier plugins-dist/forum/formulaires/forum.html, dans la ligne
  

  (#ENV*erreurs|table_valeurprevisu)

  
  je remplace #ENV* par #ENV**, alors en mode parano ($filtrer_javascript = -1 ;) le script javascript, qui s’affichait en dessous du bloc de prévisualisation, ne s’affiche plus.

  Vu que inc-forum_previsu.html, qui alimente "previsu", semble gérer sa propre sécurité, est-il nécessaire de repasser une deuxième fois par le filtrage de sécurité, ce qui génère un échappement du script situé à la fin de inc-forum_previsu.html ?

• How to run bash script from NodeJS application correctly ?

  13 mars 2019, par z Eyeland

  I am running a node application that uses spawn child-process to start this script

  #!/bin/bash
  
  FILEPATH="$1"
  
  COMPRESSIONPATH="$2"
  
  ffmpeg -i $FILEPATH -vcodec h264 -acodec mp2 $COMPRESSIONPATH
  
  sudo rm $FILEPATH
  
  curl -H "Content-Type:application/json" -X GET 
  
  http://localhost:3000/clovis/api/led

  The script never finishes. If the ffmpeg compression command takes long then x amount of time then the process just stops and holds the process. I cant tell so by using the command ps-ef. Is there another way to start bash scripts from NodeJS other then spawn ? Does the NodeJS child-process have a time limit ?

• Download a part of youtube video using a powershell script

  26 octobre 2024, par Nguyễn Đức Minh

  I'm writing this Powershell script :

  


  $URL = "https://www.youtube.com/watch?v=KbuwueqEJL0"
$from = 00:06:15
$to = 00:09:17

$cmdOutput = (youtube-dl --get-url $URL) 

ffmpeg -ss $from -to $to -i  -ss $from -to $to -i  output.mkv


  


  This script's purpose is to download a part of a Youtube video. I've set the variable $URL to specify the Youtube URL, while $from and $to is the start and end time of the part I want to download.

  


  $cmdOutput is used to output the stream URL. The output would have two lines : the first one is the URL for the video stream, while the second one is the audio stream URL.

  


  Currently, I don't know how to use the output as a variable and specify the line number of $cmdOutput to put it into the correct stream. I guess and would be replaced by something like $cmdOutput[line 1], and $cmdOutput[line 2], though I know that those are incorrect.

  


  I've consulted this answer, and it is handy for me to write this script. I've also read Boris Lipschitz's answer on how to do the same thing with Python, but his answer does not work.

  


  In that script, the -ss flag inputs the seeking point, and the -t <duration></duration> flag tells FFmpeg to stop encoding after the specified duration. For example, if the start time is 00:02:00 and the duration is 00:03:00, FFmpeg would download from 00:02:00 to 00:05:00, which is not the expected outcome. For some reason, his Python script skips the first 5 seconds of output, even if I replace the -t flag with -to . I've tried to edit his script, but it does not work unless you explicitly specify the time for both video and audio stream, as well as their respective stream URL.
