• run ffmpeg from PHP web script

  18 février 2014, par it6

  I need to manage the recording/capture of a website mindwhile it is running a slide-show to get videos form these slides.

  My approach is :

  <?php 
  
  
  
  define('FFMPEG_LIBRARY', '/usr/bin/ffmpeg ');
  
  
  
  $ffmpegcmd = "ffmpeg -f x11grab -r 25 -s 800x600 -i :0.0 /tmp/output.mpg";
  
  
  
  shell_exec($ffmpegcmd);  
  
  
  
  ?>

  But i get this error from php error log :

  [x11grab @ 0x81e8aa0] device: :0.0 -> display: :0.0 x: 0 y: 0 width: 800 height: 600
  
  No protocol specified
  
  No protocol specified
  
  [x11grab @ 0x81e8aa0] Could not open X display.
  
  :0.0: Input/output error

  Similar command from console run good.

  Please, any help to get display and be able to control ffmpeg from browser php script ?

  Thanks in advance.

  thanks for your time.

  I got rid the X display error, but not I still haven't got the capture.

  Using xvfb I get an unknown file at /tmp written by www-data user :
   rw-r—r— 1 www-data www-data 11252 Sep 12 09:49 server-B20D7FC79C7F597315E3E501AEF10E0D866E8E92.xkm

  Running startx I got also an unknown file at /tmp
   rw------- 1 www-data www-data 59 Sep 12 09:53 serverauth.oLcFlG7tXC

  any of both grow in size so it is not capturing anything. The content is some binary thing.
  What are those files about ?

  What I am trying is to write a script in which I can control the time ffmpeg is capturing the desktop to create a video from a jquery slide displayed on a website.

  My try from console is closer, but if I can do it by browser I will be able to know when to stop sending an AJAX request once the slide is finished.

  This is my try from console :

  #!/bin/bash
  
  
  
  # start the slide website: I will need to change it to control by querystring the language and course level
  
  firefox http://www.languagecourse.net/vocabulary-trainer.php &
  
  # start recording: I will need to adjust the frame to capture
  
  ffmpeg -f x11grab -r 25 -s 800x600 -i :0.0 /tmp/output2.mpg &
  
  # since I can't control the time a course takes I pause an arbitrary time
  
  sleep 5
  
  # look for the capture PID and close it
  
  for i in $(ps aux | grep ffmpeg | sed "s/  */#/g" | cut -f2 -d#)
  
  do
  
    echo "proceso $i killed"
  
    kill -9 $i
  
  done

  I wonder once the website is opened I can continue doing the control from AJAX, but not know if I will be able to get the ffmpeg PID to stop the command.

  I will appreciate any kind of comments.

• Anomalie #4831 (Nouveau) : URLs arbo non mise à jour au changement de rubrique

  23 juin 2021, par Julien Tessier

  Etapes pour reproduire :¶

  • Utiliser les URL arbos
  • Créer un article "Lorem ipsum" dans la rubrique 1
  • Publier l’article, son URL est /rubrique-1/lorem-ipsum
  • Créer un article "Lorem ipsum" dans la rubrique 2
  • Proposer l’article à la publication, son URL est /rubrique-2/lorem-ipsum
  • Déplacer l’article dans la rubrique 1
  • SPIP génère une erreur dans les logs :
    

    2021-06-23 11:32:54 127.0.0.1 (pid 498) :Pri:ERREUR : Erreur 1062 de mysql : Duplicate entry ’1-lorem-ipsum’ for key ’PRIMARY’

  • Publier l’article
  • L’URL du nouvel article est inchangée donc il est inaccessible (= son URL a déjà été "prise" par un autre)

  Comportement attendu¶

  Au changement de rubrique, URL arbos regénère une URL unique (avec l’ID donc).
