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

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 tube-update tube.db

2. Watch / Listen from websites

library watch maker.db

To stop playing press Ctrl+C in either the terminal or mpv

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=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!

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

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

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")

        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

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

$ 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

$ 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

$ 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

IRIs vs URLs

    XKLB should:
        - print paths as unquoted UTF-8 IRIs (by default)
        - accept either IRIs or URLs as input with optional flags to make parsing/searching explicitly use one or the other
        - save paths to the database "AS-IS"

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.

$ library regex-sort -h
usage: library regex-sort [input_path | stdin] [output_path | stdout]

regex-sort is effectively a text-processing pipeline with the following steps:

line_splitter -- split lines into "words" (--regex)
word_sorter -- sort words within each line (--word-sort)
line_sorter -- sort lines (--line-sort)

Examples:

    If your data has a lot of repeating rows it will help to sort by dup count:
        --line-sort dup,natsort

    You can use any matching regex to produce sorting words:
        --regex \b\w\w+\b  # word boundaries (default)
        --regex \b\d+\b    # digits
        --regex '.{3}'     # char counts

        --regex '.{3}' --line-sort dup,natsort -v
        (0, ((' Ja',), ('Sva',), ('aye',), ('lba',), ('n M',), ('rd ',)))  # Svalbard and Jan Mayen
        (0, ((' La',), ('Sri',), ('nka',)))  # Sri Lanka
        (0, ((' Ma',), ('San',), ('rin',)))  # San Marino
        (0, ((' Ri',), ('Pue',), ('rto',)))  # Puerto Rico
        (0, (('And',), ('orr',)))  # Andorra
        (0, (('Arm',), ('eni',)))  # Armenia

    You can use 'mcda' as a strategy for ranking multiple sort score criteria:
        --word-sorts '-dup, mcda, count, -len, -lastindex, alpha' \\  # count, -len, -lastindex, alpha are weighted by entropy
        --line-sorts '-allunique, alpha, mcda, alldup, dupmode, line'  # alldup, dupmode, line are weighted by entropy

$ library extract-links -h

[fpart](https://github.com/martymac/fpart) or [fpsync](https://www.fpart.org/fpsync/) will be better.

$ 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/

$ library columns -h
usage: library columns PATH ... [--table STR] [--start-row INT]

Print columns from table-like files

Only print column names

$ 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`

$ 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%

$ library process-ffmpeg -h
usage: library process-ffmpeg PATH ... [--always-split] [--split-longer-than DURATION] [--min-split-segment SECONDS] [--simulate]

Resize videos to max 1440x960px AV1 and/or Opus to save space

Convert audio to Opus. Optionally split up long tracks into multiple files.

    fd -tf -eDTS -eAAC -eWAV -eAIF -eAIFF -eFLAC -eAIFF -eM4A -eMP3 -eOGG -eMP4 -eWMA -j4 -x library process --audio

Use --always-split to _always_ split files if silence is detected

    library process-audio --always-split audiobook.m4a

Use --split-longer-than to _only_ detect silence for files in excess of a specific duration

    library process-audio --split-longer-than 36mins audiobook.m4b audiobook2.mp3

Calculate how much space you could save via process-ffmpeg by running something like this:

    numfmt --to=iec (sqlite-utils --no-headers --raw-lines ~/lb/video.db "select sum(size)-sum(duration*100000) from media where time_deleted=0 and video_count>=1 and video_codecs != 'av1' and size/duration > 100000")

$ library process-image -h
usage: library process-image PATH ...

Resize images to max 2400x2400px and format AVIF to save space

Calculate how much space you could save via process-image by running something like this:

$ 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-target-columns --only-new-rows --table media,playlists --pk path --skip-column id audio-fts.db audio.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

 Split DBs using --where

     library merge-dbs --pk path big.db specific-site.db -v --only-new-rows -t media,playlists -w 'path like "https://specific-site%"'

$ library copy-play-counts -h

$ library download -h
usage: library download DATABASE [--prefix /mnt/d/] --video [--subs] [--auto-subs] [--small] | --audio | --photos [--safe]

Files will be saved to //. The default prefix is the current working directory.

By default things will download in a random order

    library download dl.db --prefix ~/output/path/root/

But you can sort; eg. oldest first

    library download dl.db -u m.time_modified,m.time_created

Limit downloads to a specified playlist URLs

    library fs video.db --to-json --playlists https://www.youtube.com/c/BlenderFoundation/videos | library download --video video.db --from-json -

Limit downloads to a specified video URLs or substring

Print list of queued up downloads

    library download --print

Print list of saved playlists

    library playlists dl.db -p a

Print download queue groups

    library download-status audio.db

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 watch -h
usage: library watch DATABASE [optional args]

Control playback

    To stop playback press Ctrl-C in either the terminal or mpv

    Or use `lb next` or `lb stop`

    Or create global shortcuts in your desktop environment by sending commands to mpv_socket
    echo 'playlist-next force' | socat - /run/user/1000/mpv_socket  # library listen default
    echo 'playlist-next force' | socat - /home/xk/.config/mpv/socket  # library watch default

    If you prefer you can also send mpv the playlist, but this is incompatible with post-actions
    mpv --playlist=(lb wt videos.db --ext mp4 -l 50 -p fw | psub)  # fish shell, mark 50 videos as watched
    mpv --playlist=<(lb wt videos.db --ext mp4 -p f)  # BASH, all videos

$ 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

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 -h

Exact file matches

    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

$ library merge-online-local -h
