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 library

Should also work on Mac OS.

External dependencies

Required: ffmpeg

Some features work better with: mpv, fd-find, 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 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

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=library 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=library 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')
end

Usage

Create database subcommands

fs-add

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

tube-add

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

web-add

Add open-directory media

$ library web-add -h
usage: library web-add [--filesystem | --video | --audio | --image | --text] DATABASE URL ...

Scan open directories (multiple profiles can be selected or none at all)

    library web-add open_dir.db http://1.1.1.1/  # simple spider
    library web-add open_dir.db --filesystem http://1.1.1.1/
    library web-add open_dir.db --video http://1.1.1.1/
    library web-add open_dir.db --filesystem --video http://1.1.1.1/

Re-scan using a different profile

    library media v.db -w 'size is null' --ext wmv,3gp,mp4 -pf | library web-add --media --force --video v.db -

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

gallery-add

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 -

tabs-add

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)

links-add

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 with pagination

By default it will add the URL param "?page=2" and so on...

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)

Import lines from stdin

    cb | library linksdb example_dbs/links.db --skip-extract -

IRIs vs URLs

    Library 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"

How I use it

    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

site-add

Auto-scrape website data to SQLite

$ library site-add -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/

tables-add

Add table-like data to SQLite

$ library tables-add -h
usage: library tables-add DATABASE PATH ... [--table STR] [--end-row INT]

Insert data from one or more files into a SQLite database

reddit-add

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.
You can find more info here: https://github.com/chapmanjacobd/reddit_mining#how-was-this-made

regex-sort

Sort text by regex split and corpus comparison

$ 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

extract-links

Folder subcommands

merge-mv

Move files and merge folders in BSD/rsync style, rename if possible

$ library merge-mv -h
usage: library merge-mv SOURCE ... DEST [--simulate] [--ext EXT]

merging-move: combine file trees

The destination is ALWAYS a folder by default (`--dest-folder`).
Use `--dest-bsd` to mimick BSD/GNU default `mv` behavior
Use `--dest-file` to mimick BSD/GNU `mv --no-target-directory`

By default it won't matter if source folders end with a path separator or not

    library merge-mv folder1  folder2/  # folder1 will be merged with folder2/
    library merge-mv folder1/ folder2/  # folder1 will be merged with folder2/

--bsd mode: an ending path separator determines if each source is to be placed within or merged with the destination

    library merge-mv --bsd folder1/ folder2/  # folder1 will be merged with folder2/
    library merge-mv --bsd folder1  folder2/  # folder1 will be moved to folder2/folder1/

--parent mode: always include the parent folder name when merging

    library merge-mv --parent folder1  folder2/  # folder1 will be moved to folder2/folder1/
    library merge-mv --parent folder1/ folder2/  # folder1 will be moved to folder2/folder1/
    library merge-mv --parent file1.txt folder2/ # file1 will be moved to folder2/file1_parent_folder/file1.txt

nb. This tool, like other library subcommands, only works on files. Empty folders will not be moved to the destination

Move files/folders without losing hierarchy metadata with --relative or relmv

    Move fresh music to your phone every Sunday

merge-folders

Merge two or more file trees, check for conflicts before merging

$ library merge-folders -h
usage: library merge-folders [--replace] [--no-replace] [--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.

mergerfs-cp

cp files with reflink on mergerfs

$ library mergerfs-cp -h
usage: library mergerfs-cp SOURCE ... DEST [--simulate] [--ext EXT]

This command mirrors the behavior of BSD with regard to destination files and folders.
To force the destination to always be a folder, similar to `library mv`, use `--destination-folder`

Copy files with reflink and handle mergerfs mounts

    library mergerfs-cp --dry-run d/files* d/folder2/
    cp --interactive --reflink=always /mnt/d9/files1.txt /mnt/d9/folder2/files1.txt
    ...

    btrfs fi du /mnt/d3/files1.txt /mnt/d3/folder2/files1.txt
        Total   Exclusive  Set shared  Filename
    12.57GiB       0.00B    12.57GiB  /mnt/d3/files1.txt
    12.57GiB       0.00B    12.57GiB  /mnt/d3/folder2/files1.txt

scatter

Scatter files between folders or disks

$ library scatter -h
usage: library scatter [--limit LIMIT] [--policy POLICY] [--sort SORT] --targets TARGETS DATABASE RELATIVE_PATH ...

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}

Balance files across filesystem folder trees or multiple devices (mostly useful for mergerfs)

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-device re-bin: balance device inodes for specific subfolder

    library scatter -m /mnt/d1:/mnt/d2 fs.db subfolder --group count --sort 'size desc'

Multi-device re-bin: only consider the most recent 100 files

    library scatter -m /mnt/d1:/mnt/d2 -l 100 -s 'time_modified desc' fs.db /

Multi-device re-bin: empty out a disk (/mnt/d2) into many other disks (/mnt/d1, /mnt/d3, and /mnt/d4)

    library scatter fs.db -m /mnt/d1:/mnt/d3:/mnt/d4 /mnt/d2

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.

mv-list

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 library 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 library 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/

incremental-diff

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`

Media File subcommands

media-check

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%

process-media

Estimate and execute potential disk space savings

$ library process-media -h
usage: library process-media DATABASE_OR_PATH

Running fsadd first to create a video database will be faster because it runs many files in parallel

    library fsadd --video video.db ~/Videos/
    library process-media video.db

But using media folder/file paths directly is also supported

    library process-media ~/Videos/

Find invalid media to attempt to transcode or delete

    library process-media --invalid --no-valid --delete-unplayable video.db

If not installed, related file extensions will be skipped during scan:

    - FFmpeg is required for shrinking video and audio
    - ImageMagick is required for shrinking images
    - Calibre is required for shrinking eBooks

Inspired somewhat by https://nikkhokkho.sourceforge.io/?page=FileOptimizer

process-ffmpeg

Shrink video/audio to AV1/Opus format (.mkv, .mka)

$ 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")
    numfmt --to=iec (sqlite-utils --no-headers --raw-lines ~/lb/audio.db "select sum(size)-sum(duration*18000) from media where time_deleted=0 and video_count=0 and audio_count>=1 and audio_codecs != 'opus' and size/duration > 18000")

Multi-database subcommands

merge-dbs

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

    library merge-dbs --pk id --only-tables subreddits audio.db reddit/81_New_Music.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%"'

copy-play-counts

download

Download media

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

Files will be saved to <prefix>/<extractor>/. 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

    library download dl.db --include https://www.youtube.com/watch?v=YE7VzlLtp-4
    library download dl.db -s https://www.youtube.com/watch?v=YE7VzlLtp-4  # equivalent

Maximizing the variety of subdomains

    library download photos.db --photos --image --sort "ROW_NUMBER() OVER ( PARTITION BY SUBSTR(m.path, INSTR(m.path, '//') + 2, INSTR( SUBSTR(m.path, INSTR(m.path, '//') + 2), '/') - 1) )"

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

Download checked videos

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

download-status

Show download status

$ library download-status -h
usage: library download-status DATABASE

redownload

Re-download deleted/lost media

$ library redownload -h
usage: library redownload DATABASE

If you have previously downloaded YouTube or other online media, but your
hard drive failed or you accidentally deleted something, and if that media
is still accessible from the same URL, this script can help to redownload
everything that was scanned-as-deleted between two timestamps.

$ 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

tabs-open

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
