Usage

IMPORTANT

SubMiner requires the bundled Yomitan instance to have at least one dictionary imported for lookups to work. See Yomitan setup for details.

Just finished first-run setup?

If you want Anki card enrichment (sentence, audio, screenshot), the only config you need is ankiConnect with your deck name and field names. Here is a minimal working example:

{
  "ankiConnect": {
    "enabled": true,
    "deck": "Mining",
    "fields": {
      "sentence": "Sentence",
      "audio": "SentenceAudio",
      "image": "Picture",
    },
  },
}

Field names must match your Anki note type exactly (case-sensitive). See Anki Integration for the full reference.

How It Works

1. SubMiner starts the overlay app in the background
2. MPV runs with an IPC socket at /tmp/subminer-socket
3. The overlay connects and subscribes to subtitle changes
4. Subtitles are tokenized with Yomitan's internal parser
5. Words are displayed as interactive spans in the overlay
6. Hover a word, then trigger Yomitan lookup with your configured lookup key/modifier to open the Yomitan popup
7. Optional subtitle annotations (N+1, character-name, frequency, JLPT) highlight useful cues in real time

There are several ways to use SubMiner:

TIP

New users: start with the subminer wrapper script (or the SubMiner mpv shortcut on Windows). It handles mpv launch, IPC socket setup, and overlay lifecycle automatically so you don't need to configure anything in mpv.conf.

Approach	Use when	How
subminer script	You want SubMiner to handle everything — launch mpv, set up the socket, start the overlay. The simplest path and recommended starting point.	subminer video.mkv
SubMiner mpv shortcut (Windows)	The recommended Windows entry point. Created during first-run setup, launches mpv with SubMiner's defaults directly.	Double-click, drag a file onto it, or run SubMiner.exe --launch-mpv
MPV plugin (all platforms)	You launch mpv yourself or from another tool (file manager, Jellyfin, etc.). Requires --input-ipc-server=/tmp/subminer-socket in your mpv config.	Use y chord keybindings inside mpv

You can use both — the plugin provides in-player controls, while the subminer script (or the Windows shortcut) is convenient for direct playback. The subminer script runs directly via shebang on Linux and macOS (no bun run needed); on Windows it must be invoked with bun run subminer since the shebang is not supported.

Live Config Reload

While SubMiner is running, it watches your active config file and applies safe updates automatically.

Live-updated settings:

• subtitleStyle
• keybindings
• shortcuts
• secondarySub.defaultMode
• ankiConnect.ai

Invalid config edits are rejected; SubMiner keeps the previous valid runtime config and shows an error notification. For restart-required sections, SubMiner shows a restart-needed notification.

Commands

On Windows, replace SubMiner.AppImage with SubMiner.exe in the direct packaged-app examples below.

Logging and App Mode

• --log-level controls logger verbosity.
• --dev and --debug are app/dev-mode switches; they are not log-level aliases.
• --background defaults to quieter logging (warn) unless --log-level is set.
• --background launched from a terminal detaches and returns the prompt; stop it with tray Quit or SubMiner.AppImage --stop (SubMiner.exe --stop on Windows).
• Linux desktop launcher starts SubMiner with --background by default (via electron-builder linux.executableArgs).
• On Linux, the app now defaults safeStorage to gnome-libsecret for encrypted token persistence. Launcher pass-through commands also support --password-store=<backend> and forward it to the app when present. Override with e.g. --password-store=basic_text.
• Use both when needed, for example SubMiner.AppImage --start --dev --log-level debug (or SubMiner.exe --start --dev --log-level debug on Windows).

Windows mpv Shortcut

First-run setup creates the config file, then requires the mpv plugin and Yomitan dictionaries before it can finish.

If you enabled the optional Windows shortcut during install, SubMiner creates a SubMiner mpv shortcut in the Start menu and/or on the desktop. On Windows, that shortcut is the recommended way to launch local files with SubMiner because it starts mpv.exe with the right defaults directly. After setup completes, the shortcut is the normal Windows playback entry point.

You can use it three ways:

• Double-click SubMiner mpv to open mpv with SubMiner's default socket/subtitle args.
• Drag a video file onto SubMiner mpv to launch that file with the same defaults.
• Run it directly from Command Prompt or PowerShell with --launch-mpv.

& "C:\Program Files\SubMiner\SubMiner.exe" --launch-mpv
& "C:\Program Files\SubMiner\SubMiner.exe" --launch-mpv "C:\Videos\episode 01.mkv"

This flow requires mpv.exe to be discoverable. Leave mpv.executablePath blank to auto-discover from PATH, or set it to the full mpv.exe path if mpv is installed elsewhere. SUBMINER_MPV_PATH is still honored as a fallback.

Launcher Subcommands

• subminer jellyfin / subminer jf: Jellyfin-focused workflow aliases.
• subminer doctor: health checks for core dependencies and runtime paths.
• subminer config: config helpers (path, show).
• subminer mpv: mpv helpers (status, socket, idle).
• subminer dictionary <path>: generates a Yomitan-importable character dictionary ZIP from a file/directory target.
• subminer texthooker: texthooker-only shortcut (same behavior as --texthooker).
• subminer app / subminer bin: direct passthrough to the SubMiner binary/AppImage.
• Subcommand help pages are available (for example subminer jellyfin -h).

First-Run Setup

Setup popup appears on first launch, or when setup has not been completed.

You can also open it manually:

subminer --setup
SubMiner.AppImage --setup

Setup flow:

• config file: create the default config directory and prefer config.jsonc
• plugin status: install the bundled mpv plugin before finishing setup
• Yomitan shortcut: open bundled Yomitan settings directly from the setup window
• dictionary check: ensure at least one bundled Yomitan dictionary is available, unless an external Yomitan profile is configured
• Windows: optionally create or remove SubMiner mpv Start Menu/Desktop shortcuts (SubMiner.exe --launch-mpv)
• Windows: optionally set mpv.executablePath if mpv.exe is not on PATH
• refresh: re-check plugin + dictionary state without restarting
• Finish setup stays disabled until the config, plugin, and dictionary gates are satisfied
• finish action writes setup completion state and suppresses future auto-open prompts

AniList character dictionary auto-sync (optional):

• Enable with anilist.characterDictionary.enabled=true in config.
• SubMiner syncs the currently watched AniList media into a per-media snapshot, then rebuilds one merged SubMiner Character Dictionary from the most recently used snapshots.
• Rotation limit defaults to 3 recent media snapshots in that merged dictionary (maxLoaded).

Use subcommands for Jellyfin workflows (subminer jellyfin ...). Top-level launcher flags like --jellyfin-* are intentionally rejected.

MPV Profile Example (mpv.conf)

subminer passes the following MPV options directly on launch by default:

• --input-ipc-server=/tmp/subminer-socket (or your configured socket path)
• --alang=ja,jp,jpn,japanese,en,eng,english,enus,en-us
• --slang=ja,jp,jpn,japanese,en,eng,english,enus,en-us
• --sub-auto=fuzzy
• --sub-file-paths=.;subs;subtitles
• --sid=auto
• --secondary-sid=auto
• --secondary-sub-visibility=no

You can append additional MPV arguments with launcher -a/--args, for example --args "--ao=alsa --volume=80".

You can define a matching profile in ~/.config/mpv/mpv.conf for consistency when launching mpv manually or from other tools. The Windows SubMiner.exe --launch-mpv shortcut path uses equivalent args directly, but skips the extra current-directory subtitle scan to avoid duplicate sidecar detection when you drag a video onto the shortcut; the optional profile remains useful for manual mpv launches and the subminer wrapper defaults to --profile=subminer (or override with subminer -p <profile> ...):

[subminer]
# IPC socket (must match SubMiner config)
input-ipc-server=/tmp/subminer-socket

# Prefer JP/EN audio + subtitle language variants
alang=ja,jp,jpn,japanese,en,eng,english,enus,en-us
slang=ja,jp,jpn,japanese,en,eng,english,enus,en-us

# Auto-load external subtitles
sub-auto=fuzzy
sub-file-paths=.;subs;subtitles

# Select primary + secondary subtitle tracks automatically
sid=auto
secondary-sid=auto
secondary-sub-visibility=no

Yomitan setup

SubMiner includes a bundled Yomitan extension for overlay word lookup. This bundled extension is separate from any Yomitan browser extension you may have installed.

For SubMiner overlay lookups to work, open Yomitan settings (subminer app --settings or SubMiner.AppImage --settings) and import at least one dictionary in the bundled Yomitan instance.

If you also use Yomitan in a browser, configure that browser profile separately; it does not inherit dictionaries or settings from the bundled instance.

YouTube Playback

subminer accepts direct URLs (for example, YouTube links) and ytsearch: targets. For YouTube playback, SubMiner resolves subtitle selection during startup while mpv is paused: it auto-selects the default primary subtitle track plus a best-effort secondary track, then resumes when primary subtitles are ready.

Notes:

• Install yt-dlp so mpv can resolve YouTube streams and subtitle tracks reliably.
• For YouTube URLs, startup no longer requires opening the picker first; SubMiner loads subtitles and keeps the overlay available for retries.
• Press Ctrl+Alt+C during active YouTube playback to open the manual YouTube subtitle picker and retry track selection.
• For YouTube URLs, subminer probes available YouTube subtitle tracks, reuses existing authoritative tracks when available, and downloads only missing sides.
• Native mpv secondary subtitle rendering stays hidden so the overlay remains the visible secondary subtitle surface.
• Primary subtitle target languages come from youtube.primarySubLanguages (defaults to ["ja","jpn"]).
• Secondary target languages come from secondarySub.secondarySubLanguages (defaults to English if unset).
• Configure defaults in $XDG_CONFIG_HOME/SubMiner/config.jsonc (or ~/.config/SubMiner/config.jsonc) under youtube and secondarySub.

For local video files, SubMiner uses the same config-driven language priorities to auto-select the primary and secondary subtitle tracks from internal and external subtitle sources.

Controller Support

SubMiner supports gamepad/controller input for couch-friendly usage via the Chrome Gamepad API. Controller input drives the overlay while keyboard-only mode is enabled.

Getting Started

1. Connect a controller before or after launching SubMiner.
2. Enable keyboard-only mode — press Y on the controller (default binding) or use the overlay keybinding.
3. Press Alt+C in the overlay by default to pick the controller you want to save and remap any action inline.
4. Click Learn on the overlay action you want, then press the matching button, trigger, or stick direction on the controller.
5. Use the left stick to navigate subtitle tokens and scroll the popup; use the right stick vertically for popup page jumps.
6. Press A to look up the selected word, X to mine a card, B to close the popup.

By default SubMiner uses the first connected controller. Alt+C opens the controller config modal, where you can save the preferred controller and remap bindings inline, and Alt+Shift+C opens the live debug modal with raw axes/button values for non-standard pads. Both shortcuts can be changed through shortcuts.openControllerSelect and shortcuts.openControllerDebug.

Default Button Mapping

Button	Action
A (South)	Toggle lookup
B (East)	Close lookup
Y (North)	Toggle keyboard-only mode
X (West)	Mine card
L1	Play current Yomitan audio
R1	Next Yomitan audio track
L3 (left stick press)	Toggle mpv pause
Select / Minus	Quit mpv
L2 / R2	Unbound (available for custom bindings)

Analog Controls

Input	Action
Left stick horizontal	Move token selection left/right
Left stick vertical	Scroll Yomitan popup
Right stick vertical	Jump through Yomitan popup
D-pad	Fallback for stick navigation when configured

Learn mode ignores already-held inputs and waits for the next fresh button press or axis direction, which avoids accidental captures when you open the modal mid-input.

All button and axis mappings are configurable under the controller config block. See Configuration — Controller Support for the full options.

Keybindings

See Keyboard Shortcuts for the full reference, including mining shortcuts, overlay controls, and customization.

Global shortcuts (work system-wide):

Keybind	Action
Alt+Shift+O	Toggle visible overlay
Alt+Shift+Y	Open Yomitan settings

Alt+Shift+Y is fixed and not configurable. All other shortcuts can be changed under shortcuts in your config.

Useful overlay-local default keybinding: Ctrl+Alt+P opens the playlist browser for the current video's parent directory and the live mpv queue so you can append, reorder, remove, or jump between episodes without leaving playback.

Ctrl/Cmd+Shift+H opens the session help modal with the current overlay and mpv keybindings. If you use the mpv plugin, the same help view is also available through the y-h chord.

Hovering over subtitle text pauses mpv by default; leaving resumes it. Yomitan popups also pause playback by default. Set subtitleStyle.autoPauseVideoOnHover: false or subtitleStyle.autoPauseVideoOnYomitanPopup: false to disable either behavior.

Drag-and-Drop

• Drop video files onto the overlay to replace current playback.
• Hold Shift while dropping to append to the playlist instead.
