xk library

Project description

lb: xk media library

A wise philosopher once told me, "The future is autotainment".

Manage large media libraries. Similar to Plex but more minimalist. Primary usage is local filesystem but also supports some virtual constructs like tracking video playlists (eg. YouTube subscriptions) or daily browser tabs.

Required: ffmpeg

Recommended: mpv, fish, firefox

Install

Linux recommended but Windows setup instructions available.

pip install xklb

$ library
xk media library [lb]

local media subcommands:
  fsadd [extract, xr]                Create a local media database; Add folders

  listen [lt]                        Listen to local media
  watch [wt]                         Watch local media
  filesystem [fs]                    Browse files
  bigdirs [largefolders]             View folders which take up much room

online media subcommands:
  tubeadd [ta]                       Create a tube database; Add playlists
  tubelist [playlist, playlists]     List added playlists
  tubeupdate [tu]                    Get new videos for your saved playlists
  tubewatch [tw, tube, entries]      Watch the tube
  tubelisten [tl]                    Listen to the tube

browser tabs subcommands:
  tabsadd                            Create a tabs database; Add URLs
  tabs [tb]                          Open your tabs for the day

Quick Start -- watch online media on your PC

wget https://github.com/chapmanjacobd/lb/raw/main/examples/mealtime.tw.db
library tubewatch mealtime.tw.db

Quick Start -- listen to online media on a chromecast group

wget https://github.com/chapmanjacobd/lb/raw/main/examples/music.tl.db
lb tubelisten music.tl.db -ct "House speakers"

Start -- 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.

lb fsadd tv.db ./video/folder/

termtosvg

2. Watch / Listen from local files

lb wt tv.db                          # the default post-action is to do nothing
lb wt tv.db --post-action delete     # delete file after playing
lb lt finalists.db --post-action=ask # ask whether to delete after playing

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

Start -- online media

1. Download Metadata

Download playlist and channel metadata. Break free of the YouTube algo~

lb tubeadd educational.db https://www.youtube.com/c/BranchEducation/videos

termtosvg

And you can always add more later--even from different websites.

lb 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.

lb tubeadd maker.db --yt-dlp-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. On a high-speed connection (>500 Mbps), it can take up to five hours to download the metadata for 180,000 videos.

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.

lb tubeupdate

2. Watch / Listen from websites

lb tubewatch maker.db

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

Start -- tabs (visit websites on a schedule)

tabs is a way to organize your visits to URLs that you want to visit every once in a while.

If you want to track changes to websites over time there are better tools out there, like huginn, urlwatch, or changedetection.io.

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

lb tabsadd --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 lb tabs to cron

lb tabs is meant to run once per day. Here is how you would configure it with crontab:

45 9 * * * DISPLAY=:0 lb tabs /home/my/tabs.db

You can also invoke tabs manually:

lb tabs -L 1  # open one tab

Things to know.db

When the database file path is not specified, video.db will be created / used.

library fsadd ./tv/

The same for audio: audio.db will be created / used.

library fsadd --audio ./music/

Likewise, fs.db from:

library fsadd --filesystem /any/path/

If you want to specify more than one directory you need to mention the db file explicitly.

library fsadd --filesystem one/
library fsadd --filesystem fs.db one/ two/

Organize via separate databases.

library fsadd --audio both.db ./audiobooks/ ./podcasts/
library fsadd --audio audiobooks.db ./audiobooks/
library fsadd --audio podcasts.db ./podcasts/ ./another/more/secret/podcasts_folder/

Usage

$ library watch -h
usage: lb 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

If not specified, watch will try to read video.db in the working directory:
    lb watch
    lb watch ./my/other/database/is-a/db.db

Override the default player (mpv):
    lb 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:
    lb watch --player "vlc --vlc-opts"

Cast to chromecast groups:
    lb watch --cast --cast-to "Office pair"
    lb watch -ct "Office pair"  # equivalent
    If you don't know the exact name of your chromecast group run `catt scan`

Print instead of play:
    lb watch --print --limit 10  # print the next 10 files
    lb watch -p -L 10  # print the next 10 files
    lb watch -p  # this will print _all_ the media. be cautious about `-p` on an unfiltered set

    Printing modes
    lb watch -p    # print in a table
    lb watch -p p  # equivalent
    lb watch -p a  # print an aggregate report
    lb watch -p f  # print fields -- useful for piping paths to utilities like xargs or GNU Parallel

    Check if you have downloaded something before
    lb watch -u duration -p -s 'title'

    Print an aggregate report of deleted media
    lb watch -w is_deleted=1 -p a

    Open ipython with all of your media
    lb watch -vv -p --cols '*'

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):
    lb watch -L inf
    lb watch -l inf
    lb watch --queue inf
    lb watch -L 99999999999999999999999

    You may also want to restrict the play queue.
    For example, when you only want 1000 random files:
    lb 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:
    lb watch -S 10  # offset ten from the top of an ordered query

Repeat
    lb watch                  # listen to 120 random songs (DEFAULT_PLAY_QUEUE)
    lb watch --limit 5        # listen to FIVE songs
    lb watch -l inf -u random # listen to random songs indefinitely
    lb 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.
    lb watch --include happy  # only matches will be included
    lb watch -s happy         # equivalent
    lb watch --exclude sad   # matches will be excluded
    lb watch -E sad          # equivalent

    Search only the path column
    lb watch -O -s 'path : mad max'

    Double spaces are parsed as one space
    -s '  ost'        # will match OST and not ghost
    -s toy story      # will match '/folder/toy/something/story.mp3'
    -s 'toy  story'    # will match more strictly '/folder/toy story.mp3'

Constrain media by arbitrary SQL expressions:
    lb watch --where audio_count = 2  # media which have two audio tracks
    lb watch -w "language = 'eng'"    # media which have an English language tag
                                           (this could be audio _or_ subtitle)
    lb watch -w subtitle_count=0      # media that doesn't have subtitles

Constrain media to duration (in minutes):
    lb watch --duration 20
    lb watch -d 6  # 6 mins ±10 percent (ie. between 5 and 7 mins)
    lb watch -d-6  # less than 6 mins
    lb watch -d+6  # more than 6 mins

    Duration can be specified multiple times:
    lb watch -d+5 -d-7  # should be similar to -d 6

    If you want exact time use `where`
    lb watch --where 'duration=6*60'

Constrain media to file size (in megabytes):
    lb watch --size 20
    lb watch -z 6  # 6 MB ±10 percent (ie. between 5 and 7 MB)
    lb watch -z-6  # less than 6 MB
    lb watch -z+6  # more than 6 MB

Constrain media by throughput:
    Bitrate information is not explicitly saved.
    You can use file size and duration as a proxy for throughput:
    lb watch -w 'size/duration<50000'

Constrain media to portrait orientation video:
    lb watch --portrait
    lb watch -w 'width<height' # equivalent

Specify media play order:
    lb watch --sort duration   # play shortest media first
    lb watch -u duration desc  # play longest media first
    You can use multiple SQL ORDER BY expressions
    lb watch -u subtitle_count > 0 desc # play media that has at least one subtitle first

Play media in order (similarly named episodes):
    lb watch --play-in-order
    There are multiple strictness levels of --play-in-order.
    If things aren't playing in order try adding more `O`s:
    lb watch -O    # normal
    lb watch -OO   # slower, more complex algorithm
    lb watch -OOO  # strict

Post-actions -- choose what to do after playing:
    lb watch --post-action delete  # delete file after playing
    lb watch -k ask  # ask after each whether to keep or delete

    lb watch -k askkeep  # ask after each whether to move to a keep folder or delete
    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:
    lb watch -k askkeep --keep-dir /home/my/music/keep/

Experimental options:
    Duration to play (in seconds) while changing the channel
    lb watch --interdimensional-cable 40
    lb watch -4dtv 40

rsync

I use rsync to move files instead of copy-on-write duplication because I want deletions to stick. When I press the next button in the car I delete the song from my curated universe.

function mrmusic
    rsync -a --remove-source-files --files-from=(
        lb lt ~/lb/audio.db -s /mnt/d/80_Now_Listening/ -p f             --moved /mnt/d/80_Now_Listening/ /mnt/d/ | psub
    ) /mnt/d/80_Now_Listening/ /mnt/d/

    rsync -a --remove-source-files --files-from=(
        lb lt ~/lb/audio.db -w play_count=0 -u random -L 1200 -p f             --moved /mnt/d/ /mnt/d/80_Now_Listening/ | psub
    ) /mnt/d/ /mnt/d/80_Now_Listening/
end
