A wise philosopher once told me: "the future is autotainment".
Manage and curate large media libraries. An index for your archive. Primary usage is local filesystem but also supports some virtual constructs like tracking online video playlists (eg. YouTube subscriptions) and scheduling browser tabs.
Linux recommended but Windows setup instructions available.
pip install xklb
Should also work on Mac OS.
Required: ffmpeg
Some features work better with: mpv, fd-find, fish
Local media
For thirty terabytes of video the initial scan takes about four hours to complete.
After that, subsequent scans of the path (or any subpaths) are much quicker--only
new files will be read by ffprobe.
library fsadd tv.db ./video/folder/
library watch tv.db # the default post-action is to do nothing
library watch tv.db --post-action delete # delete file after playing
library listen finalists.db -k ask_keep # ask whether to keep file after playing
To stop playing press Ctrl+C in either the terminal or mpv
Online media
Download playlist and channel metadata. Break free of the YouTube algo~
library tubeadd educational.db https://www.youtube.com/c/BranchEducation/videos
And you can always add more later--even from different websites.
library tubeadd maker.db https://vimeo.com/terburg
To prevent mistakes the default configuration is to download metadata for only the most recent 20,000 videos per playlist/channel.
library tubeadd maker.db --extractor-config playlistend=1000
Be aware that there are some YouTube Channels which have many items--for example the TEDx channel has about 180,000 videos. Some channels even have upwards of two million videos. More than you could likely watch in one sitting--maybe even one lifetime. On a high-speed connection (>500 Mbps), it can take up to five hours to download the metadata for 180,000 videos.
TIP! If you often copy and paste many URLs you can paste line-delimited text as arguments via a subshell. For example, in fish shell with cb:
library tubeadd my.db (cb)
Or in BASH:
library tubeadd my.db $(xclip -selection c)
Tubeupdate will go through the list of added playlists and fetch metadata for any videos not previously seen.
library tube-update tube.db
library watch maker.db
To stop playing press Ctrl+C in either the terminal or mpv

Visit websites on a schedule
tabs is a way to organize your visits to URLs that you want to remember every once in a while.
The main benefit of tabs is that you can have a large amount of tabs saved (say 500 monthly tabs) and only the smallest amount of tabs to satisfy that goal (500/30) tabs will open each day. 17 tabs per day seems manageable--500 all at once does not.
The use-case of tabs are websites that you know are going to change: subreddits, games, or tools that you want to use for a few minutes daily, weekly, monthly, quarterly, or yearly.
library tabsadd tabs.db --frequency monthly --category fun \
https://old.reddit.com/r/Showerthoughts/top/?sort=top&t=month \
https://old.reddit.com/r/RedditDayOf/top/?sort=top&t=month
library tabs is meant to run once per day. Here is how you would configure it with crontab:
45 9 * * * DISPLAY=:0 library tabs /home/my/tabs.db
Or with systemd:
tee ~/.config/systemd/user/tabs.service
[Unit]
Description=xklb daily browser tabs
[Service]
Type=simple
RemainAfterExit=no
Environment="DISPLAY=:0"
ExecStart=library tabs /home/my/tabs.db
tee ~/.config/systemd/user/tabs.timer
[Unit]
Description=xklb daily browser tabs timer
[Timer]
Persistent=yes
OnCalendar=*-*-* 9:58
[Install]
WantedBy=timers.target
systemctl --user daemon-reload
systemctl --user enable --now tabs.service
You can also invoke tabs manually:
library tabs tabs.db -L 1 # open one tab
Incremental surfing. 📈🏄 totally rad!
Curate with library big-dirs
If you are looking for candidate folders for curation (ie. you need space but don't want to buy another hard drive). The big-dirs subcommand was written for that purpose:
$ library big-dirs fs/d.db
You may filter by folder depth (similar to QDirStat or WizTree)
$ library big-dirs --depth=3 audio.db
There is also an flag to prioritize folders which have many files which have been deleted (for example you delete songs you don't like--now you can see who wrote those songs and delete all their other songs...)
$ library big-dirs --sort-groups-by deleted audio.db
Recently, this functionality has also been integrated into watch/listen subcommands so you could just do this:
$ library watch --big-dirs ./my.db
$ lb wt -B # shorthand equivalent

BTW, for some cols like time_deleted you'll need to specify a where clause so they aren't filtered out:
$ library watch -p f -col time_deleted -w time_deleted'>'0 | lowcharts timehist -w 80
Add local media
$ library fs-add -h
usage: library fs-add [(--video) | --audio | --image | --text | --filesystem] DATABASE PATH ...
The default database type is video
library fsadd tv.db ./tv/
library fsadd --video tv.db ./tv/ # equivalent
You can also create audio databases. Both audio and video use ffmpeg to read metadata
library fsadd --audio audio.db ./music/
Image uses ExifTool
library fsadd --image image.db ./photos/
Text will try to read files and save the contents into a searchable database
library fsadd --text text.db ./documents_and_books/
Create a text database and scan with OCR and speech-recognition
library fsadd --text --ocr --speech-recognition ocr.db ./receipts_and_messages/
Create a video database and read internal/external subtitle files into a searchable database
library fsadd --scan-subtitles tv.search.db ./tv/ ./movies/
Decode media to check for corruption (slow)
library fsadd --check-corrupt
# See media-check command for full options
Normally only relevant filetypes are included. You can scan all files with this flag
library fsadd --scan-all-files mixed.db ./tv-and-maybe-audio-only-files/
# I use that with this to keep my folders organized
library watch -w 'video_count=0 and audio_count>=1' -pf mixed.db | parallel mv {} ~/d/82_Audiobooks/
Remove path roots with --force
library fsadd audio.db /mnt/d/Youtube/
[/mnt/d/Youtube] Path does not exist
library fsadd --force audio.db /mnt/d/Youtube/
[/mnt/d/Youtube] Path does not exist
[/mnt/d/Youtube] Building file list...
[/mnt/d/Youtube] Marking 28932 orphaned metadata records as deleted
If you run out of RAM, for example scanning large VR videos, you can lower the number of threads via --threads
library fsadd vr.db --delete-unplayable --check-corrupt --full-scan-if-corrupt 15% --delete-corrupt 20% ./vr/ --threads 3
Move files on import
library fsadd audio.db --move ~/library/ ./added_folder/
This will run destination paths through `library christen` and move files relative to the added folder root
Add online video media (yt-dlp)
$ library tube-add -h
usage: library tube-add [--safe] [--extra] [--subs] [--auto-subs] DATABASE URL ...
Create a dl database / add links to an existing database
library tubeadd dl.db https://www.youdl.com/c/BranchEducation/videos
Add links from a line-delimited file
cat ./my_yt_subscriptions.txt | library tubeadd reddit.db -
Add metadata to links already in a database table
library tubeadd --force reddit.db (sqlite-utils --raw-lines reddit.db 'select path from media')
Fetch extra metadata
By default tubeadd will quickly add media at the expense of less metadata.
If you plan on using `library download` then it doesn't make sense to use `--extra`.
Downloading will add the extra metadata automatically to the database.
You can always fetch more metadata later via tubeupdate
library tube-update tw.db --extra
Add open-directory media
$ library web-add -h
usage: library web-add [(--filesystem) | --video | --audio | --image | --text] DATABASE URL ...
Scan open directories
library web-add open_dir.db --video http://1.1.1.1/
Check download size of all videos matching some criteria
library download --fs open_dir.db --prefix ~/d/dump/video/ -w 'height<720' -E preview -pa
path count download_duration size avg_size
--------- ------- ---------------------------- --------- ----------
Aggregate 5694 2 years, 7 months and 5 days 724.4 GiB 130.3 MiB
Download all videos matching some criteria
library download --fs open_dir.db --prefix ~/d/dump/video/ -w 'height<720' -E preview
Stream directly to mpv
library watch open_dir.db
Add online gallery media (gallery-dl)
$ library gallery-add -h
usage: library gallery-add DATABASE URL ...
Add gallery_dl URLs to download later or periodically update
If you have many URLs use stdin
cat ./my-favorite-manhwa.txt | library galleryadd your.db --insert-only -
Create a tabs database; Add URLs
$ library tabs-add -h
usage: library tabs-add [--frequency daily weekly (monthly) quarterly yearly] [--no-sanitize] DATABASE URL ...
Adding one URL
library tabsadd -f daily tabs.db https://wiby.me/surprise/
Depending on your shell you may need to escape the URL (add quotes)
If you use Fish shell know that you can enable features to make pasting easier
set -U fish_features stderr-nocaret qmark-noglob regex-easyesc ampersand-nobg-in-token
Also I recommend turning Ctrl+Backspace into a super-backspace for repeating similar commands with long args
echo 'bind \b backward-kill-bigword' >> ~/.config/fish/config.fish
Importing from a line-delimitated file
library tabsadd -f yearly -c reddit tabs.db (cat ~/mc/yearly-subreddit.cron)
Create a link-scraping database
$ library links-add -h
usage: library links-add DATABASE PATH ... [--case-sensitive] [--cookies-from-browser BROWSER[+KEYRING][:PROFILE][::CONTAINER]] [--selenium] [--manual] [--scroll] [--auto-pager] [--poke] [--chrome] [--local-html] [--file FILE]
Database version of extract-links
You can fine-tune what links get saved with --path/text/before/after-include/exclude.
library links-add --path-include /video/
Import links from args
library links-add --no-extract links.db (cb)

Create a reddit database; Add subreddits
$ library reddit-add -h
usage: library reddit-add [--lookback N_DAYS] [--praw-site bot1] DATABASE URL ...
Fetch data for redditors and reddits
library redditadd interesting.db https://old.reddit.com/r/coolgithubprojects/ https://old.reddit.com/user/Diastro
If you have a file with a list of subreddits you can do this
library redditadd 96_Weird_History.db --subreddits (cat ~/mc/96_Weird_History-reddit.txt)
Likewise for redditors
library redditadd shadow_banned.db --redditors (cat ~/mc/shadow_banned.txt)
To remove entries (for example when you get 404s)
library search-db reddit.db playlists --or --exact subreddit1 subreddit2 --soft-delete
Note that reddit's API is limited to 1000 posts and it usually doesn't go back very far historically.
Also, it may be the case that reddit's API (praw) will stop working in the near future. For both of these problems
my suggestion is to use pushshift data.

This tool is intended for local use. If transferring many small files across the network something like
[fpart](https://github.com/martymac/fpart) or [fpsync](https://www.fpart.org/fpsync/) will be better.
Find specific folders to move to different disks
$ library mv-list -h
usage: library mv-list [--limit LIMIT] [--lower LOWER] [--upper UPPER] MOUNT_POINT DATABASE
Free up space on a specific disk. Find candidates for moving data to a different mount point
The program takes a mount point and a xklb database file. If you don't have a database file you can create one like this
library fsadd --filesystem d.db ~/d/
But this should definitely also work with xklb audio and video databases
library mv-list /mnt/d/ video.db
The program will print a table with a sorted list of folders which are good candidates for moving.
Candidates are determined by how many files are in the folder (so you don't spend hours waiting for folders with millions of tiny files to copy over).
The default is 4 to 4000--but it can be adjusted via the --lower and --upper flags.

Diff large table-like files in chunks
$ library incremental-diff -h
usage: library incremental-diff PATH1 PATH2 [--join-keys JOIN_KEYS] [--table1 TABLE1] [--table2 TABLE2] [--table1-index TABLE1_INDEX] [--table2-index TABLE2_INDEX] [--start-row START_ROW] [--batch-size BATCH_SIZE]
See data differences in an incremental way to quickly see how two different files differ.
Data (PATH1, PATH2) can be two different files of different file formats (CSV, Excel) or it could even be the same file with different tables.
If files are unsorted you may need to use `--join-keys id,name` to specify ID columns. Rows that have the same ID will then be compared.
If you are comparing SQLITE files you may be able to use `--sort id,name` to achieve the same effect.
To diff everything at once run with `--batch-size inf`
Check video and audio files for corruption via ffmpeg
$ library media-check -h
usage: library media-check [--chunk-size SECONDS] [--gap SECONDS OR 0.0-1.0*DURATION] [--delete-corrupt >0-100] [--full-scan] [--audio-scan] PATH ...
Defaults to decode 0.5 second per 10% of each file
library media-check ./video.mp4
Decode all the frames of each file to evaluate how corrupt it is
(scantime is very slow; about 150 seconds for an hour-long file)
library media-check --full-scan ./video.mp4
Decode all the packets of each file to evaluate how corrupt it is
(scantime is about one second of each file but only accurate for formats where 1 packet == 1 frame)
library media-check --full-scan --gap 0 ./video.mp4
Decode all audio of each file to evaluate how corrupt it is
(scantime is about four seconds per file)
library media-check --full-scan --audio ./video.mp4
Decode at least one frame at the start and end of each file to evaluate how corrupt it is
(scantime is about one second per file)
library media-check --chunk-size 5% --gap 99.9% ./video.mp4
Decode 3s every 5% of a file to evaluate how corrupt it is
(scantime is about three seconds per file)
library media-check --chunk-size 3 --gap 5% ./video.mp4
Delete the file if 20 percent or more of checks fail
library media-check --delete-corrupt 20% ./video.mp4
To scan a large folder use `fsadd`. I recommend something like this two-stage approach
library fsadd --delete-unplayable --check-corrupt --chunk-size 5% tmp.db ./video/ ./folders/
library media-check (library fs tmp.db -w 'corruption>15' -pf) --full-scan --delete-corrupt 25%
The above can now be done in one command via `--full-scan-if-corrupt`
library fsadd --delete-unplayable --check-corrupt --chunk-size 5% tmp.db ./video/ ./folders/ --full-scan-if-corrupt 15% --delete-corrupt 25%

Merge SQLITE databases
$ library merge-dbs -h
usage: library merge-dbs SOURCE_DB ... DEST_DB [--only-target-columns] [--only-new-rows] [--upsert] [--pk PK ...] [--table TABLE ...]
Merge-DBs will insert new rows from source dbs to target db, table by table. If primary key(s) are provided,
and there is an existing row with the same PK, the default action is to delete the existing row and insert the new row
replacing all existing fields.
Upsert mode will update each matching PK row such that if a source row has a NULL field and
the destination row has a value then the value will be preserved instead of changed to the source row's NULL value.
Ignore mode (--only-new-rows) will insert only rows which don't already exist in the destination db
Test first by using temp databases as the destination db.
Try out different modes / flags until you are satisfied with the behavior of the program
library merge-dbs --pk path tv.db movies.db (mktemp --suffix .db)
Merge database data and tables
library merge-dbs --upsert --pk path tv.db movies.db video.db

library merge-dbs --only-new-rows --pk subreddit,path --only-tables reddit_posts audio.db reddit/81_New_Music.db -v
To skip copying primary-keys from the source table(s) use --business-keys instead of --primary-keys

Check videos before downloading
library watch open_dir.db --online-media-only --loop --exit-code-confirm -i --action ask-keep -m 4 --start 35% --volume=0 -w 'height<720' -E preview
Assuming you have bound in mpv input.conf a key to 'quit' and another key to 'quit 4',
using the ask-keep action will mark a video as deleted when you 'quit 4' and it will mark a video as watched when you 'quit'.
For example, here I bind "'" to "KEEP" and "j" to "DELETE"
' quit
j quit 4
This is pretty intuitive after you use it a few times but another option is to
define your own post-actions
`--cmd5 'echo {} >> keep.txt' --cmd6 'echo {} >> rejected.txt'`
But you will still bind keys in mpv input.conf
k quit 5 # goes to keep.txt
r quit 6 # goes to rejected.txt

library download --fs open_dir.db --prefix ~/d/dump/video/ -w 'id in (select media_id from history)'

Show what is currently playing
$ library now -h
usage: library now
Print now playing
Play next file and optionally delete current file
$ library next -h
usage: library next
Go to the next track in the playqueue, optionally delete the currently playing media
Set playback to a certain time, fast-forward or rewind
$ library seek -h
usage: library seek
Seek to an exact time
library seek 5:30 # 5 minutes, 30 seconds
library seek 5:30:00 # 5 hours, 30 minutes
Seek forward or backward a relative duration
library seek +5:00 # 5 minutes forward
library seek +5: # 5 minutes forward
library seek +5 # 5 seconds forward
library seek 5 # 5 seconds forward
library seek -5 # 5 seconds backward
Stop all playback
$ library stop -h
usage: library stop
Stop playback (close mpv, turn off chromecast, etc)

$ library pause -h
usage: library pause
Pause playback (pause mpv, pause chromecast, etc)
Open your tabs for the day
$ library tabs-open -h
usage: library tabs-open DATABASE
Tabs is meant to run **once per day**. Here is how you would configure it with `crontab`
45 9 * * * DISPLAY=:0 library tabs /home/my/tabs.db
If things aren't working you can use `at` to simulate a similar environment as `cron`
echo 'fish -c "export DISPLAY=:0 && library tabs /full/path/to/tabs.db"' | at NOW
Also, if you're just testing things out be aware that `tabs-add` assumes that you visited the
website right before adding it; eg. if you use `tabs-add --frequency yearly` today the tab won't
open until one year from now (at most). You can override this default
library tabs-add --allow-immediate ...
To re-"play" some tabs, delete some history
library history ~/lb/tabs.db --played-within '1 day' -L inf -p --delete-rows
library tabs ~/lb/tabs.db
You can also invoke tabs manually
library tabs -L 1 # open one tab
Print URLs
library tabs -w "frequency='yearly'" -p
View how many yearly tabs you have
library tabs -w "frequency='yearly'" -p a
Delete URLs
library tabs -p -s cyber

Dedupe SQLITE tables
$ library dedupe-db -h
usage: library dedupe-dbs DATABASE TABLE --bk BUSINESS_KEYS [--pk PRIMARY_KEYS] [--only-columns COLUMNS]

It should not need to be said but *backup* your database before trying this tool!
Dedupe-DB will help remove duplicate rows based on non-primary-key business keys
library dedupe-db ./video.db media --bk path
By default all non-primary and non-business key columns will be upserted unless --only-columns is provided
If --primary-keys is not provided table metadata primary keys will be used
If your duplicate rows contain exactly the same data in all the columns you can run with --skip-upsert to save a lot of time

library dedupe-media --fs video.db
Dedupe based on duration and file basename or dirname similarity
library dedupe-media video.db --duration --basename -s release_group # pre-filter with a specific text substring
library dedupe-media video.db --duration --basename -u m1.size # sort such that small files are treated as originals and larger files are deleted
library dedupe-media video.db --duration --basename -u 'm1.size desc' # sort such that large files are treated as originals and smaller files are deleted
Dedupe online against local media
library dedupe-media --compare-dirs video.db / http
Merge online and local data
$ library merge-online-local -h
usage: library merge-online-local DATABASE
