xk library
Project description
library (media toolkit)
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.
Install
Linux recommended but Windows setup instructions available.
pip install xklb
Should also work on Mac OS.
External dependencies
Required: ffmpeg
Some features work better with: mpv, firefox, fish
Getting started
Local media
1. Extract Metadata
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/
2. Watch / Listen from local files
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
1. Download Metadata
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)
1a. Get new videos for saved playlists
Tubeupdate will go through the list of added playlists and fetch metadata for any videos not previously seen.
library tubeupdate tube.db
2. Watch / Listen from websites
library watch maker.db
To stop playing press Ctrl+C in either the terminal or mpv

Browser Tabs
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.
1. Add your websites
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
2. Add library tabs to cron
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="/usr/bin/fish" "-c" "lb tabs /home/xk/lb/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!
Find large folders
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
Backfill data
Backfill missing YouTube videos from the Internet Archive
for base in https://youtu.be/ http://youtu.be/ http://youtube.com/watch?v= https://youtube.com/watch?v= https://m.youtube.com/watch?v= http://www.youtube.com/watch?v= https://www.youtube.com/watch?v=
sqlite3 video.db "
update or ignore media
set path = replace(path, '$base', 'https://web.archive.org/web/2oe_/http://wayback-fakeurl.archive.org/yt/')
, time_deleted = 0
where time_deleted > 0
and (path = webpath or path not in (select webpath from media))
and path like '$base%'
"
end
Backfill reddit databases with pushshift data
https://github.com/chapmanjacobd/reddit_mining/
for reddit_db in ~/lb/reddit/*.db
set subreddits (sqlite-utils $reddit_db 'select path from playlists' --tsv --no-headers | grep old.reddit.com | sed 's|https://old.reddit.com/r/\(.*\)/|\1|' | sed 's|https://old.reddit.com/user/\(.*\)/|u_\1|' | tr -d "\r")
~/github/xk/reddit_mining/links/
for subreddit in $subreddits
if not test -e "$subreddit.csv"
echo "octosql -o csv \"select path,score,'https://old.reddit.com/r/$subreddit/' as playlist_path from `../reddit_links.parquet` where lower(playlist_path) = '$subreddit' order by score desc \" > $subreddit.csv"
end
end | parallel -j8
for subreddit in $subreddits
sqlite-utils upsert --pk path --alter --csv --detect-types $reddit_db media $subreddit.csv
end
library tubeadd --safe --ignore-errors --force $reddit_db (sqlite-utils --raw-lines $reddit_db 'select path from media')

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
Usage
Create database subcommands
Add local media (fsadd)
$ library fsadd -h
usage: library fsadd [(--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 --io-multiplier
library fsadd vr.db --delete-unplayable --check-corrupt --full-scan-if-corrupt 15% --delete-corrupt 20% ./vr/ --io-multiplier 0.2
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) (tubeadd)
$ library tubeadd -h
usage: library tubeadd [--safe] [--extra] [--subs] [--auto-subs] DATABASE URLS ...
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 tubeupdate tw.db --extra
Add online gallery media (gallery-dl) (galleryadd)
$ library galleryadd -h
usage: library galleryadd DATABASE URLS
Add gallery_dl URLs to download later or periodically update
If you have many URLs use stdin
cat ./my-favorite-manhwa.txt | library galleryadd my.db --insert-only -
Create a tabs database; Add URLs (tabsadd)
$ library tabsadd -h
usage: library tabsadd [--frequency daily weekly (monthly) quarterly yearly] [--no-sanitize] DATABASE URLS ...
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 (links-add)
$ 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/
Defaults to stop fetching
After encountering ten known links:
library links-add --stop-known 10
library links-add --stop-link https://special.fish/specific_pacific
Some websites don't give an error when you try to access pages which don't exist.
To compensate for this the script will only continue fetching pages until there are both no new nor known links for one-hundred pages:
library links-add --stop-pages-no-match 100
Backfill fixed number of pages
You can disable automatic stopping by any of the following:
1. Set `--fixed-pages` to the desired number of pages
2. Set `--stop-link` to an unlikely URL
3. Set `--stop-known` to an absurdly high number
If the website is supported by --auto-pager data is fetched twice when using page iteration.
As such, page iteration (--max-pages, --fixed-pages, etc) is disabled when using `--auto-pager`.
To use "&p=1" instead of "&page=1"
library links-add --page-key p
By default the script will attempt to modify each given URL with "&page=1".
Single page
If `--fixed-pages` is 1 and --start-page is not set then the URL will not be modified.
library links-add --fixed-pages=1
Loading page https://site/path
library links-add --fixed-pages=1 --page-start 99
Loading page https://site/path?page=99
Reverse chronological paging
library links-add --max-pages 10
library links-add --fixed-pages (overrides --max-pages and --stop-known but you can still stop early via --stop-link ie. 429 page)
Chronological paging
library links-add --page-start 100 --page-step 1
library links-add --page-start 100 --page-step=-1 --fixed-pages=5 # go backwards
# TODO: store previous page id (max of sliding window)
Jump pages
Some pages don't count page numbers but instead count items like messages or forum posts. You can iterate through like this:
library links-add --page-key start --page-start 0 --page-step 50
which translates to
&start=0 first page
&start=50 second page
&start=100 third page
Page folders
Some websites use paths instead of query parameters. In this case make sure the URL provided includes that information with a matching --page-key
library links-add --page-key page https://website/page/1/
library links-add --page-key article https://website/article/1/
Import media paths directly
library links-add --no-extract links.db
Examples
library links-add links.db https://video/site/ --path-include /video/
library links-add links.db https://loginsite/ --path-include /article/ --cookies-from-browser firefox
library links-add links.db https://loginsite/ --path-include /article/ --cookies-from-browser chrome
library links-add --path-include viewtopic.php --cookies-from-browser firefox \
--page-key start --page-start 0 --page-step 50 --fixed-pages 14 --stop-pages-no-match 1 \

Auto-scrape website data to SQLITE (siteadd)
$ library siteadd -h
usage: library site-add DATABASE PATH ... [--auto-pager] [--poke] [--local-html] [--file FILE]
Extract data from website requests to a database
library siteadd jobs.st.db --poke https://hk.jobsdb.com/hk/search-jobs/python/
Run with `-vv` to see and interact with the browser
Create a reddit database; Add subreddits (redditadd)
$ library redditadd -h
usage: library redditadd [--lookback N_DAYS] [--praw-site bot1] DATABASE URLS ...
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)
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.
You can find more info here: https://github.com/chapmanjacobd/reddit_mining#how-was-this-made
Convert pushshift data to reddit.db format (stdin)
$ library pushshift -h
usage: library pushshift DATABASE < stdin
Download data (about 600GB jsonl.zst; 6TB uncompressed)
wget -e robots=off -r -k -A zst https://files.pushshift.io/reddit/submissions/
Load data from files via unzstd
unzstd --memory=2048MB --stdout RS_2005-07.zst | library pushshift pushshift.db
Or multiple (output is about 1.5TB SQLITE fts-searchable):
for f in psaw/files.pushshift.io/reddit/submissions/*.zst
echo "unzstd --memory=2048MB --stdout $f | library pushshift (basename $f).db"
library optimize (basename $f).db
end | parallel -j5

Playback subcommands
Watch / Listen
$ library watch -h
usage: library watch DATABASE [optional args]
Control playback:
To stop playback press Ctrl-C in either the terminal or mpv
Create global shortcuts in your desktop environment by sending commands to mpv_socket:
echo 'playlist-next force' | socat - /tmp/mpv_socket
Override the default player (mpv):
library does a lot of things to try to automatically use your preferred media player
but if it doesn't guess right you can make it explicit:
library watch --player "vlc --vlc-opts"
Cast to chromecast groups:
library watch --cast --cast-to "Office pair"
library watch -ct "Office pair" # equivalent
If you don't know the exact name of your chromecast group run `catt scan`
Play media in order (similarly named episodes):
library watch --play-in-order
library watch -O # equivalent
The default sort value is 'natural_ps' which means media will be sorted by parent path
and then stem in a natural way (using the integer values within the path). But there are many other options:
Options:
- reverse: reverse the sort order
- compat: treat characters like '⑦' as '7'
Algorithms:
- natural: parse numbers as integers
- os: sort similar to the OS File Explorer sorts. To improve non-alphanumeric sorting on Mac OS X and Linux it is necessary to install pyicu (perhaps via python3-icu -- https://gitlab.pyicu.org/main/pyicu#installing-pyicu)
- path: use natsort "path" algorithm (https://natsort.readthedocs.io/en/stable/api.html#the-ns-enum)
- human: use system locale
- ignorecase: treat all case as equal
- lowercase: sort lowercase first
- signed: sort with an understanding of negative numbers
- python: sort like default python
Values:
- path
- parent
- stem
- title (or any other column value)
- ps: parent, stem
- pts: parent, title, stem
Use this format: algorithm, value, algorithm_value, or option_algorithm_value.
For example:
- library watch -O human
- library watch -O title
- library watch -O human_title
- library watch -O reverse_compat_human_title
- library watch -O path # path algorithm and parent, stem values (path_ps)
- library watch -O path_path # path algorithm and path values
Also, if you are using --random you need to fetch sibling media to play the media in order:
- library watch --random --fetch-siblings each -O # get the first result per directory
- library watch --random --fetch-siblings if-audiobook -O # get the first result per directory if 'audiobook' is in the path
- library watch --random --fetch-siblings always -O # get 2,000 results per directory
If searching by a specific subpath it may be preferable to just sort by path instead
library watch d/planet.earth.2024/ -u path
library watch --related # Similar to -O but uses fts to find similar content
library watch -R # equivalent
library watch -RR # above, plus ignores most filters
library watch --cluster # cluster-sort to put similar-named paths closer together
library watch -C # equivalent
library watch --big-dirs # Recommended to use with --duration or --depth filters; see `lb big-dirs -h` for more info
library watch -B # equivalent
All of these options can be used together but it will be a bit slow and the results might be mid-tier
as multiple different algorithms create a muddied signal (too many cooks in the kitchen):
library watch -RRCO
You can even sort the items within each cluster by auto-MCDA ~LOL~
library watch -B --sort-groups-by 'mcda median_size,-deleted'
library watch -C --sort-groups-by 'mcda median_size,-deleted'
Filter media by file siblings of parent directory:
library watch --sibling # only include files which have more than or equal to one sibling
library watch --solo # only include files which are alone by themselves
`--sibling` is just a shortcut for `--lower 2`; `--solo` is `--upper 1`
library watch --sibling --solo # you will always get zero records here
library watch --lower 2 --upper 1 # equivalent
You can be more specific via the `--upper` and `--lower` flags
library watch --lower 3 # only include files which have three or more siblings
library watch --upper 3 # only include files which have fewer than three siblings
library watch --lower 3 --upper 3 # only include files which are three siblings inclusive
library watch --lower 12 --upper 25 -O # on my machine this launches My Mister 2018
Play recent partially-watched videos (requires mpv history):
library watch --partial # play newest first
library watch --partial old # play oldest first
library watch -P o # equivalent
library watch -P p # sort by percent remaining
library watch -P t # sort by time remaining
library watch -P s # skip partially watched (only show unseen)
The default time used is "last-viewed" (ie. the most recent time you closed the video)
If you want to use the "first-viewed" time (ie. the very first time you opened the video)
library watch -P f # use watch_later file creation time instead of modified time
You can combine most of these options, though some will be overridden by others.
library watch -P fo # this means "show the oldest videos using the time I first opened them"
library watch -P pt # weighted remaining (percent * time remaining)
Print instead of play:
library watch --print --limit 10 # print the next 10 files
library watch -p -L 10 # print the next 10 files
library watch -p # this will print _all_ the media. be cautious about `-p` on an unfiltered set
Printing modes
library watch -p # print as a table
library watch -p a # print an aggregate report
library watch -p b # print a big-dirs report (see library bigdirs -h for more info)
library watch -p f # print fields (defaults to path; use --cols to change)
# -- useful for piping paths to utilities like xargs or GNU Parallel
library watch -p d # mark deleted
library watch -p w # mark watched
Some printing modes can be combined
library watch -p df # print files for piping into another program and mark them as deleted within the db
library watch -p bf # print fields from big-dirs report
Check if you have downloaded something before
library watch -u duration -p -s 'title'
Print an aggregate report of deleted media
library watch -w time_deleted!=0 -p=a

Set the play queue size:
By default the play queue is 120--long enough that you likely have not noticed
but short enough that the program is snappy.
If you want everything in your play queue you can use the aid of infinity.
Pick your poison (these all do effectively the same thing):
library watch -L inf
library watch -l inf
library watch --queue inf
library watch -L 999999999999
You may also want to restrict the play queue.
For example, when you only want 1000 random files:
library watch -u random -L 1000
Offset the play queue:
You can also offset the queue. For example if you want to skip one or ten media:
library watch --skip 10 # offset ten from the top of an ordered query
Repeat
library watch # listen to 120 random songs (DEFAULT_PLAY_QUEUE)
library watch --limit 5 # listen to FIVE songs
library watch -l inf -u random # listen to random songs indefinitely
library watch -s infinite # listen to songs from the band infinite
Constrain media by search:
Audio files have many tags to readily search through so metadata like artist,
album, and even mood are included in search.
Video files have less consistent metadata and so only paths are included in search.
library watch --include happy # only matches will be included
library watch -s happy # equivalent
library watch --exclude sad # matches will be excluded
library watch -E sad # equivalent
Search only the path column
library watch -O -s 'path : mad max'
library watch -O -s 'path : "mad max"' # add "quotes" to be more strict
Double spaces are parsed as one space
library watch -s ' ost' # will match OST and not ghost
library watch -s toy story # will match '/folder/toy/something/story.mp3'
library watch -s 'toy story' # will match more strictly '/folder/toy story.mp3'
You can search without -s but it must directly follow the database due to how argparse works
library watch my.db searching for something
Constrain media by arbitrary SQL expressions:
library watch --where audio_count = 2 # media which have two audio tracks
library watch -w "language = 'eng'" # media which have an English language tag
(this could be audio _or_ subtitle)
library watch -w subtitle_count=0 # media that doesn't have subtitles
Constrain media to duration (in minutes):
library watch --duration 20
library watch -d 6 # 6 mins ±10 percent (ie. between 5 and 7 mins)
library watch -d-6 # less than 6 mins
library watch -d+6 # more than 6 mins
Duration can be specified multiple times:
library watch -d+5 -d-7 # should be similar to -d 6
If you want exact time use `where`
library watch --where 'duration=6*60'
Constrain media to file size (in megabytes):
library watch --size 20
library watch -S 6 # 6 MB ±10 percent (ie. between 5 and 7 MB)
library watch -S-6 # less than 6 MB
library watch -S+6 # more than 6 MB
Constrain media by time_created / time_last_played / time_deleted / time_modified:
library watch --created-within '3 days'
library watch --created-before '3 years'
Constrain media by throughput:
Bitrate information is not explicitly saved.
You can use file size and duration as a proxy for throughput:
library watch -w 'size/duration<50000'
Constrain media to portrait orientation video:
library watch --portrait
library watch -w 'width<height' # equivalent
Constrain media to duration of videos which match any size constraints:
library watch --duration-from-size +700 -u 'duration desc, size desc'
Constrain media to online-media or local-media:
Not to be confused with only local-media which is not "offline" (ie. one HDD disconnected)
library watch --online-media-only
library watch --online-media-only -i # and ignore playback errors (ie. YouTube video deleted)
library watch --local-media-only
Specify media play order:
library watch --sort duration # play shortest media first
library watch -u duration desc # play longest media first
You can use multiple SQL ORDER BY expressions
library watch -u 'subtitle_count > 0 desc' # play media that has at least one subtitle first
Prioritize large-sized media
library watch --sort 'ntile(10000) over (order by size/duration) desc'
library watch -u 'ntile(100) over (order by size) desc'
Sort by count of media with the same-X column (default DESC: most common to least common value)
library watch -u same-duration
library watch -u same-title
library watch -u same-size
library watch -u same-width, same-height ASC, same-fps
library watch -u same-time_uploaded same-view_count same-upvote_ratio
No media found when using --random
In addition to -u/--sort random, there is also the -r/--random flag.
If you have a large database it should be faster than -u random but it comes with a caveat:
This flag randomizes via rowid at an earlier stage to boost performance.
It is possible that you see "No media found" or a smaller amount of media than correct.
You can bypass this by setting --limit. For example:
library watch -B --folder-size=+12GiB --folder-size=-100GiB -r -pa
path count size duration avg_duration avg_size
--------- ------- -------- ------------------------------ -------------- ----------
Aggregate 10000 752.5 GB 4 months, 15 days and 10 hours 20 minutes 75.3 MB
(17 seconds)
library watch -B --folder-size=+12GiB --folder-size=-100GiB -r -pa -l inf
path count size duration avg_duration avg_size
--------- ------- ------- --------------------------------------- -------------- ----------
Aggregate 140868 10.6 TB 5 years, 2 months, 28 days and 14 hours 20 minutes 75.3 MB
(30 seconds)
Post-actions -- choose what to do after playing:
library watch --post-action keep # do nothing after playing (default)
library watch -k delete # delete file after playing
library watch -k softdelete # mark deleted after playing
library watch -k ask_keep # ask whether to keep after playing
library watch -k ask_delete # ask whether to delete after playing
library watch -k move # move to "keep" dir after playing
library watch -k ask_move # ask whether to move to "keep" folder
The default location of the keep folder is ./keep/ (relative to the played media file)
You can change this by explicitly setting an *absolute* `keep-dir` path:
library watch -k ask_move --keep-dir /home/my/music/keep/
library watch -k ask_move_or_delete # ask after each whether to move to "keep" folder or delete
You can also bind keys in mpv to different exit codes. For example in input.conf:
; quit 5
And if you run something like:
library watch --cmd5 ~/bin/process_audio.py
library watch --cmd5 echo # this will effectively do nothing except skip the normal post-actions via mpv shortcut
When semicolon is pressed in mpv (it will exit with error code 5) then the applicable player-exit-code command
will start with the media file as the first argument; in this case `~/bin/process_audio.py $path`.
The command will be daemonized if library exits before it completes.
To prevent confusion, normal post-actions will be skipped if the exit-code is greater than 4.
Exit-codes 0, 1, 2, 3, and 4: the external post-action will run after normal post-actions. Be careful of conflicting player-exit-code command and post-action behavior when using these!
Experimental options:
Duration to play (in seconds) while changing the channel
library watch --interdimensional-cable 40
library watch -4dtv 40
Playback multiple files at once
library watch --multiple-playback # one per display; or two if only one display detected
library watch --multiple-playback 4 # play four media at once, divide by available screens
library watch -m 4 --screen-name eDP # play four media at once on specific screen
library watch -m 4 --loop --crop # play four cropped videos on a loop
library watch -m 4 --hstack # use hstack style

Open your tabs for the day
$ library tabs -h
usage: library tabs 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
You can also invoke tabs manually:
library tabs -L 1 # open one tab

Diff large table-like files in chunks (incremental-diff)
$ 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 (media-check)
$ 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 (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 (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 (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 (takes 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 (takes 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%

Calculate a hash based on small file segments (sample-hash)
$ library sample-hash -h

Calculate hashes for large files by reading only small segments of each file
library sample-hash ./my_file.mkv
The threads flag seems to be faster for rotational media but slower on SSDs
Compare files using sample-hash and other shortcuts (sample-compare)
$ library sample-compare -h
usage: library sample-hash [--threads 10] [--chunk-size BYTES] [--gap BYTES OR 0.0-1.0*FILESIZE] PATH ...
Convenience subcommand to compare multiple files using sample-hash
Folder subcommands
Merge two or more file trees (merge-folders)
$ library merge-folders -h
usage: library merge-folders [--replace] [--skip] [--simulate] SOURCES ... DESTINATION
Merge multiple folders with the same file tree into a single folder.
https://github.com/chapmanjacobd/journal/blob/main/programming/linux/misconceptions.md#mv-src-vs-mv-src
Trumps are new or replaced files from an earlier source which now conflict with a later source.
If you only have one source then the count of trumps will always be zero.
The count of conflicts also includes trumps.
Move files preserving parent folder hierarchy (relmv)
$ library relmv -h
usage: library relmv [--dry-run] SOURCE ... DEST
Move files/folders without losing hierarchy metadata
Move fresh music to your phone every Sunday:
# move last week music back to their source folders
library relmv /mnt/d/80_Now_Listening/ /mnt/d/
# move new music for this week
library relmv (
library listen audio.db --local-media-only --where 'play_count=0' --random -L 600 -p f
) /mnt/d/80_Now_Listening/
Find specific folders to move to different disks (mv-list)
$ 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.

Type "done" when finished
Type "more" to see more files
Paste a folder (and press enter) to toggle selection
Type "*" to select all files in the most recently printed table
Then it will give you a prompt:
Paste a path:
Wherein you can copy and paste paths you want to move from the table and the program will keep track for you.
Paste a path: /mnt/d/75_MovieQueue/720p/s11/
26 selected paths: 162.1 GB ; future free space: 486.9 GB
You can also press the up arrow or paste it again to remove it from the list:
Paste a path: /mnt/d/75_MovieQueue/720p/s11/
25 selected paths: 159.9 GB ; future free space: 484.7 GB
After you are done selecting folders you can press ctrl-d and it will save the list to a tmp file:
Paste a path: done
Folder list saved to /tmp/tmp7x_75l8. You may want to use the following command to move files to an EMPTY folder target:
rsync -a --info=progress2 --no-inc-recursive --remove-source-files --files-from=/tmp/tmp7x_75l8 -r --relative -vv --dry-run / jim:/free/real/estate/
Scatter files between folders or disks
$ library scatter -h
usage: library scatter [--limit LIMIT] [--policy POLICY] [--sort SORT] --targets TARGETS DATABASE RELATIVE_PATH ...
Balance files across filesystem folder trees or multiple devices (mostly useful for mergerfs)
Scatter filesystem folder trees (without mountpoints; limited functionality; good for balancing fs inodes)
library scatter scatter.db /test/{0,1,2,3,4,5,6,7,8,9}
Reduce number of files per folder (creates more folders)
library scatter scatter.db --max-files-per-folder 16000 /test/{0,1,2,3,4,5,6,7,8,9}
Multi-device re-bin: balance by size
library scatter -m /mnt/d1:/mnt/d2:/mnt/d3:/mnt/d4/:/mnt/d5:/mnt/d6:/mnt/d7 fs.db subfolder/of/mergerfs/mnt

Multi-database subcommands
Merge SQLITE databases (merge-dbs)
$ library merge-dbs -h
usage: library merge-dbs DEST_DB SOURCE_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 (mktemp --suffix .db) tv.db movies.db
Merge database data and tables
library merge-dbs --upsert --pk path video.db tv.db movies.db
library merge-dbs --only-target-columns --only-new-rows --table media,playlists --pk path --skip-column id audio-fts.db audio.db

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
