SubMiner

An all-in-one sentence mining overlay for MPV with AnkiConnect and dictionary (Yomitan) integration.

Features

• Real-time subtitle display from MPV via IPC socket
• Yomitan integration for fast, on-screen lookups
• Japanese text tokenization using MeCab with smart word boundary detection
• Integrated texthooker-ui server for use with Yomitan
• Integrated WebSocket server (if mpv_websocket is not found) to send lines to the texthooker
• AnkiConnect integration for automatic card creation with media (audio/image)
• Invisible subtitle position edit mode (Ctrl/Cmd+Shift+P, arrow keys to adjust, Enter/Ctrl+S save, Esc cancel)

Demo

Requirements

• mpv with IPC socket support
• mecab and mecab-ipadic (recommended for Japanese tokenization)
• Linux: Hyprland (hyprctl) or X11 (xdotool + xwininfo)
• macOS: Accessibility permission for window tracking

Optional but recommended: yt-dlp, fzf, rofi, chafa, ffmpegthumbnailer.

Install

Linux (AppImage)

Download the latest release from GitHub Releases:

wget https://github.com/ksyasuda/SubMiner/releases/download/v0.1.0/SubMiner-0.1.0.AppImage -O ~/.local/bin/SubMiner.AppImage
chmod +x ~/.local/bin/SubMiner.AppImage
wget https://github.com/ksyasuda/SubMiner/releases/download/v0.1.0/subminer -O ~/.local/bin/subminer
chmod +x ~/.local/bin/subminer

The subminer wrapper uses a Bun shebang, so bun must be on PATH.

From Source

git clone --recurse-submodules https://github.com/ksyasuda/SubMiner.git
cd SubMiner
make build
make install

If you already cloned without submodules:

cd SubMiner
git submodule update --init --recursive

For macOS builds, signing, and platform-specific details, see docs/installation.md.

Quick Start

1. Copy and customize config.example.jsonc to $XDG_CONFIG_HOME/SubMiner/config.jsonc (or ~/.config/SubMiner/config.jsonc).
2. Start mpv with IPC enabled:

mpv --input-ipc-server=/tmp/subminer-socket video.mkv

3. Launch SubMiner:

subminer video.mkv
# or
subminer https://youtu.be/...

Common Commands

subminer                          # pick video from current dir (fzf)
subminer -R                       # use rofi picker
subminer -d ~/Videos              # set source directory
subminer -r -d ~/Anime            # recursive search
subminer video.mkv                # launch with default mpv profile (subminer)
subminer -p gpu-hq video.mkv      # override mpv profile
subminer -T video.mkv             # disable texthooker

MPV Plugin (Optional)

cp plugin/subminer.lua ~/.config/mpv/scripts/
cp plugin/subminer.conf ~/.config/mpv/script-opts/
# or: make install-plugin

Requires mpv IPC: --input-ipc-server=/tmp/subminer-socket

Default chord prefix: y (y-y menu, y-s start, y-S stop, y-t toggle visible layer). Overlay Jimaku shortcut default: Ctrl+Shift+J (shortcuts.openJimaku).
