FFMPEG converter script

1. !/bin/bash # Define the source and destination directories

source_dir="/media/nextcloud/msgcnx/walt/files/Teacher/Math/Algebra 1/Lesson Videos" destination_dir="/media/nextcloud/msgcnx/walt/files/Teacher/Math/Algebra 1/PUBLIC Lesson Videos"

1. Check if the source directory exists

if [ ! -d "$source_dir" ]; then

   echo "Source directory not found: $source_dir"
   exit 1 

fi

1. Check if the destination directory exists

if [ ! -d "$destination_dir" ]; then

   echo "Destination directory not found: $destination_dir"
   exit 1

fi

1. Function to convert MOV files to MP4

convert_mov_to_mp4() {

   local source_file="$1"
   local destination_file="$2"
   echo "Converting $source_file"
   
   # Perform the conversion
   ffmpeg -i "$source_file" -c:v libx264 -c:a aac "$destination_file" -nostdin 2>/dev/null
   chown www-data:www-data "$destination_file"

}

1. Initialize the converted variable outside of the loop

converted=0

1. Find and convert MOV files in subdirectories

while IFS= read -r -d source_file; do

   # Get the relative path of the source file
   relative_path="${source_file#$source_dir/}"
   # Determine the destination file path
   destination_file="$destination_dir/${relative_path%.*}.mp4"
   # Check if the corresponding MP4 file already exists in the destination
   if [ ! -e "$destination_file" ]; then
       # Ensure the destination directory exists
       mkdir -p "$(dirname "$destination_file")"
       # Convert MOV to MP4 and increment the counter
       convert_mov_to_mp4 "$source_file" "$destination_file"
       converted=1
   fi

done < <(find "$source_dir" -type f -name "*.mov" -print0)

1. Remove any converted mp4 files that do not have a corresponding mov file

echo "Removing any extra files"

1. Clean the destination directory

while IFS= read -r -d mp4_file; do

   other_dir="$source_dir/${mp4_file#${destination_dir}/}"
   mov_file="${other_dir%.*}.mov"
   if [ ! -e "$mov_file" ]; then
       rm "$mp4_file"
       converted=1
       # Set the variable if any files are removed
       echo "A file was removed"
       echo "$mp4_file"
   fi

done < <(find "$destination_dir" -type f -name "*.mp4" -print0)

1. Check if any files were converted

if [ "$converted" -eq 1 ]; then

   echo "Files converted successfully."
   # sudo -u www-data php /var/www/html/next.msgcnx/occ files:scan --path=/walt/files/Teacher/Math/Algebra\ 1/Lesson\ Videos/
   sudo -u www-data php /var/www/html/next.msgcnx/occ files:scan --path="${destination_dir#/media/nextcloud/msgcnx}"
   chown -R www-data:www-data "$destination_dir"
   echo "Nextcloud scan complete."

else

   echo "No files were converted."

fi exit 0
