# CUE-sheet generator for youtube-dl

3

+

4

+

# Usage:

5

+

# 0. Install 'jq' utility

6

+

# 1. Download any audio file with metadata from YouTube or Youtube Music, e.g.

7

+

# $ youtube-dl \

8

+

# --extract-audio \

9

+

# --audio-format flac \

10

+

# --audio-quality 0 \

11

+

# --format bestaudio \

12

+

# --write-info-json \

13

+

# --output "/tmp/ytm/%(playlist_title)s/%(channel)s - %(title)s.%(ext)s" \

14

+

# https://www.youtube.com/watch?v=lVpDQnXz34M

15

+

#

16

+

# If audio file is already downloaded earlier then just fetch only its metadata:

17

+

# $ youtube-dl \

18

+

# --write-info-json \

19

+

# --skip-download \

20

+

# --output "/tmp/ytm/%(playlist_title)s/%(channel)s - %(title)s.%(ext)s" \

21

+

# https://www.youtube.com/watch?v=lVpDQnXz34M

22

+

#

23

+

# 2. Audio and metadata files MUST be named exactly similar (except extenstion),

24

+

# but it is not necessary to keep original names. Also they MUST be placed in

25

+

# the same directory. Example:

26

+

# /tmp/ytm/ABGT496.flac

27

+

# /tmp/ytm/ABGT496.info.json

28

+

#

29

+

# 3. To create CUE file run ytdlcue with a path to audio file:

30

+

# $ ytdlcue.sh /tmp/ytm/ABGT496.flac

31

+

#

32

+

# A new file will be created in the same directory:

33

+

# /tmp/ytm/ABGT496.cue
