• Anomalie #3664 : Insertion de formulaire dans l’editeur et champ obligatoire en HTML5

  25 juin 2017, par b b

  Donc, quand HTML5 est actif , il faudrait tenter d’ajouter en js un attribut novalidate aux formulaires présents dans la prévisu afin de voir si ça permet de contourner le bug.

• Reverse video using many commands in a script

  19 août 2021, par Sam

  I am trying to make a script with FFmpeg using Reverse mode, i am not able to make it work correctly, unfortunately is some weeks i am using Linux and FFmpeg, my intention is ;

  


  

  • put the original video in Reverse directory

  


  • start the script
the script make this job ;

  


  • create the directory mkdir 01-Elaborazione

  


  • FFMPEG separate the video in small clips of 5 sec and put in 01-Elaborazione
after that

  


  • create the directory mkdir 01

  


  • FFMPEG make the Reverse of the clips and put in the directory 01

  


  • create a list Originale.txt of the Reversed clips in directory 01

  


  • change the list Inversa to invert the lines (so that the FFmpeg is making the concat correctly)

  


  • FFMPEG concat all the Reversed clips using the list Inversa.txt and put the output Pronto.mp4 in the directory Reverse
after that

  


  • delete the directory 01- Elaborazione with all the files

  


  


  at the end i have to put also many done before it start, but also doing this is not doing the job i want

  


  i have to make this, because this way i do not have problem with the Ram and Swap

  


  the script is this ;

  


  # !/bin/bash

  


  cd /srv/dev-sataa24/Lavori/Z-Modifiche/Reverse

  


  mkdir 01-Elaborazione

  


  for i in *.mp4 ; do ffmpeg -i "$i" -f segment -segment_time 5 -c copy -reset_timestamps 1 01-Elaborazione/sample_%03d.mp4 -hide_banner && rm "$i"

  


  done

  


  for i in *.MP4 ; do ffmpeg -i "$i" -f segment -segment_time 5 -c copy -reset_timestamps 1 01-Elaborazione/sample_%03d.mp4 -hide_banner && rm "$i"

  


  Wait for the processes to finish

  


  wait

  


  done && cd

  


  cd /srv/dev-sataa24/Lavori/Z-Modifiche/Reverse/01-Elaborazione

  


  mkdir 01

  


  for i in .MP4 ; do ffmpeg -i "$i" -threads 1 -vf reverse -af areverse 01/"$i%..mp4"

  


  cd /srv/dev-sataa24/Lavori/Z-Modifiche/Reverse/01-Elaborazione

  


  for i in .mp4 ; do ffmpeg -i "$i" -threads 1 -vf reverse -af areverse 01/"$i%..mp4"

  


  Wait for the processes to finish

  


  wait

  


  done && cd

  


  cd /srv/dev-sataa24/Lavori/Z-Modifiche/Reverse/01-Elaborazione/01

  


  for f in *.mp4 ; do echo file '$f' >> originale.txt

  


  tac originale.txt > inversa.txt

  


  ffmpeg -f concat -safe 0 -i inversa.txt -c copy /srv/dev-sataa24/Lavori/Z-Modifiche/Reverse/Pronto.mp4

  


  Wait for the processes to finish

  


  wait

  


  cd /srv/dev-sataa24/Lavori/Z-Modifiche/Reverse

  


  rm -r 01-Elaborazione/

  


  cd

  


  done
