# 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
|
||
