anthony / CUE-sheet generator for youtube-dl

#!/bin/bash # CUE-sheet generator for youtube-dl # Usage: # 0. Install 'jq' utility # 1. Download any audio file with metadata from YouTube or Youtube Music, e.g. # $ youtube-dl \ # --extract-audio \ # --audio-format flac \ # --audio-quality 0 \ # --format bestaudio \ # --write-info-json \ # --output "/tmp/ytm/%(playlist_title)s/%(channel)s - %(title)s.%(ext)s" \ # https://www.youtube.com/watch?v=lVpDQnXz34M # # If audio file is already downloaded earlier then just fetch only its metadata: # $ youtube-dl \ # --write-info-json \ # --skip-download \ # --output "/tmp/ytm/%(playlist_title)s/%(channel)s - %(title)s.%(ext)s" \ # https://www.youtube.com/watch?v=lVpDQnXz34M # # 2. Audio and metadata files MUST be named exactly similar (except extenstion), # but it is not necessary to keep original names. Also they MUST be placed in # the same directory. Example: # /tmp/ytm/ABGT496.flac # /tmp/ytm/ABGT496.info.json # # 3. To create CUE file run ytdlcue with a path to audio file: # $ ytdlcue.sh /tmp/ytm/ABGT496.flac # # A new file will be created in the same directory: # /tmp/ytm/ABGT496.cue installed() { command -v "$1" >/dev/null 2>&1 } ! installed 'jq' && { echo "ERROR: you need to install jq!" exit 1 } audio_path="$1" # path to audiofile audio_file=`basename "$audio_path"` # audiofile name with extension audio_name=${audio_file%.*} # audiofile name without extension audio_ext=${audio_file##*.} # audiofile name extension path="`dirname "$audio_path"`/$audio_name" # path to audiofile and its name without ext json_path="$path.info.json" # path to json file with metadata created by youtube-dl cue_path="$path.cue" # path to cue sheet to be generated # echo -e "audio_path:\t$audio_path" # echo -e "audio_file:\t$audio_file" # echo -e "audio_name:\t$audio_name" # echo -e "audio_ext:\t$audio_ext" # echo -e "path:\t\t$path" # echo -e "json_path:\t$json_path" # echo -e "cue_path:\t$cue_path" [ ! -f "$audio_path" ] && { echo "ERROR: File not found: $audio_path" exit 2 } [ ! -f "$json_path" ] && { echo "ERROR: File not found: $json_path" exit 3 } echo "PERFORMER `cat "$json_path" | jq -Mc '.channel'`" > "$cue_path" echo "TITLE `cat "$json_path" | jq -Mc '.title'`" >> "$cue_path" echo "FILE \"$audio_file\" ${audio_ext^^}" >> "$cue_path" counter=1 # track counter (works only inside loop!) cat "$json_path" | jq -Mc '.chapters[]' \ | while read chapter; do number=`printf %0.2d $counter` # pad current counter with zeros time=`echo "$chapter" | jq -Mc '.start_time'` # get initial start time in seconds time=`printf '%0.2d:%0.2d:00' $((time/60)) $((time%60))` # convert start time to minutes:seconds title=`echo "$chapter" | jq -Mc '.title' | sed -r "s#[\"]##g"` # get initial chapter title performer=`echo "$title" | cut -d "-" -f 1 | sed 's#^[[:space:]]*##g' | sed 's# *$##g'` # get and trim chapter's performer (before '-') title2=`echo "$title" | cut -d "-" -f 2 | sed 's#^[[:space:]]*##g' | sed 's# *$##g'` # get and trim chapter's title (after '-') #TODO: what if dash is not delimiter between performer and title? #TODO: take $title2 if $performer and (or?) $title2 are empty printf "%-2sTRACK $number AUDIO\n" >> "$cue_path" printf "%-4sPERFORMER \"$performer\"\n" >> "$cue_path" printf "%-4sTITLE \"$title2\"\n" >> "$cue_path" printf "%-4sINDEX 01 $time\n" >> "$cue_path" counter=`expr $counter + 1` # increase counter done echo "Done!
