  apetag : Fix APE tag size check
  The size variable is (correctly) unsigned, but is passed to several functions
  
  which take signed parameters, such as avio_read, sometimes after having
  
  numbers added to it. So ensure that size remains within the bounds that
  
  these functions can handle.

• How to rename and move files in a subdirectory with an index and the folder name ... better ?

  29 octobre 2014, par krismajean

  I’m putting together a script to take .mp4 files organized into folders that described the video (eg. cat) and I’d like to do the following :

  1. rename them with the folder name and a number ;
  2. move the video into a folder named and numbered in the same manner
  3. parse the video into frames using ffmpeg

  I’m posting this here to be a reference for others and to ask about how this could be done better. It works well but I’m wondering how to make it better.

  for dir in /path/to/parent/directory/*; do
  
  cd "$dir" && result=${PWD##*/} 
  
  cd video
  
  echo $result
  
  a=1
  
      for i in *.mp4; do
  
          dafile="$(printf "_%02d.mp4" ${a})" 
  
          dafolder="$(printf "_%02d" ${a})"
  
          newfolder=$result$dafolder
  
          newfile=$result$dafile
  
          mkdir ${newfolder}
  
          mv ${i} ${newfolder}/${newfile}
  
  
  
          cd ${newfolder}
  
              ffmpeg -i ${newfile} -r 30 -f image2 ${newfolder}-\%04d.png
  
          cd ..
  
          let a=a+1
  
      done
  
  
  
  done

  I used the following links to figure out a bunch of ideas for the code :

• Get current directory name (without full path) in Bash Script
• Renaming files in a folder to sequential numbers
