  Spipmotion ne doit pas être cassé si il manque le script de vignettes, on peut s’en passer
  On utilise document_modifier et non plus revision_document
  On utilise passthru plutot que shell_exec car shell_exec ne marche pas avec safe_mode d’activé
  On force l’exécution de l’encodage direct dans le public sinon ça ne marche pas
  On ajoute dans ffmpeg_infos les infos du script d’encodage et de génération de vignettes

• ffmpeg getting syntax error when run inside shell script only.. Why ? [duplicate]

  • Unexpected ’(’ in bash [duplicate]

  OS : Raspbian

  I’m currently working on a bash script that will merge all .AVI videos in the current directory, to one .AVI file. I’ve found the following to work perfectly for me, when run directly in the terminal :

  ffmpeg -f concat -safe 0 -i <(find . -name '*.avi' -printf "file '$PWD/%p'\n") -c copy "$(date -d '-1 day' +'%F')".avi

  This works perfectly, and I find a new .AVI file listed in the current directory (with a date name from yesterday).

  Now, when I add this same command to my script (merge.sh), I get the following output :

  /home/pi/Documents/MotionScripts/merge.sh: 11: 
  
  /home/pi/Documents/MotionScripts/merge.sh: Syntax error: "(" unexpected

  This is beyond frustrating. And yes, ffmpeg command from earlier is on line 11. The script navigates to the correct directory where the multiple .avi files are stored.

  Here is the entire script :

  #!/bin/bash
  
  
  
  #This script combines multiple AVI files within the current directory, into one long video
  
  
  
  cd /media/myBook/Security/yesterday
  
  
  
  sudo mv * /home/pi/Videos/tempconversion
  
  
  
  cd /home/pi/Videos/tempconversion
  
  
  
  ffmpeg -f concat -safe 0 -i <(find . -name '*.avi' -printf "file '$PWD/%p'\n") -c copy "$(date -d '-1 day' +'%F')".avi
  
  
  
  sudo mv "$(date -d '-1 day' +'%F')".avi /media/myBook/Security/yesterday
  
  
  
  sudo rm -f *

  Why am I getting the syntax error only when the same command is being issued within an executable script ?

  RESOLVED ! Shouldn’t have used ’sh’ to run the script. Make sure the script is executable (sudo chmod +x merge.sh) and run by entering the full path.

• Time issues in ffmpeg script (MP4 to MP3 conversion)

  16 février 2018, par Alex

  I use the code below as script on my Debian PC to create MP3 files from MP4 video files for adding to podcast app on android phone.

  But each time I click pause/forward time position (not indication) is set up in random way after resuming. Please help improve the code below to solve this problem.

  for f in *.mp4; do
  
    ffmpeg -i "$f" -map 0:a -codec:a libmp3lame -b:a 96k "${f%.mp4}.mp3"
  
  done
  
  for f in *.mp3; do
  
    vbrfix -always -makevbr -lameinfo "$f" "${f%.mp3}.mp3"
  
    rm -rf vbrfix.log vbrfix.tmp
  
  done
