Interactive subtitles for mpv, that was made to help study languages.
Easily tweaked and customizable.

If Qt version doesn't work for you - use Tk. It was abandoned(2017), but maybe still works.

Requirements

mpv 0.27 (I don't know if it will work with mpv front-ends.)
Xorg (ignore for Mac users)
composite manager; xcompmgr or sth. (ignore for Mac users)
python => 3.6
python-pyqt5
python-numpy
python-beautifulsoup4
python-requests
python-lxml
python-httpx
lua
socat
pkill
xdotool (for hiding subtitles when minimizing mpv or switching window)
optional: chromium (for external translation, other browser can be specified)
optional: wget (for listening to pronunciation)

Installation

mv interSubs.py interSubs.lua interSubs_config.py ~/.config/mpv/scripts/;
Edit configuration file interSubs_config.py
Edit interSubs.lua to add option where interSubs will start automatically.
For Mac also edit configuration at interSubs.lua
On KDE(kwin) go to Compositor and uncheck "Allow applications to block compositing". Screenshot.
For Windows - port it yourself. (It does NOT work on Windows. reason) and a possible way to do it). Consider installing VirtualBox and Ubuntu or some other user-friendly distro.

Usage

Start video with mpv & select subtitles.
F5 to start/stop interSubs.
- Starts automatically with files/paths specified in interSubs.lua
Point cursor over the word to get popup with translation.
F6 to hide/show without exiting.

Buttons bellow may be reassigned in config

Left-click - show translation in your browser.
Right-click - listen to pronunciation.
Wheel - scroll through transitions in popup.
Wheel+Ctrl - resize subtitles.
Wheel+Shift - change subtitles' vertical position.
Wheel-click - cycle through auto_pause options.
Wheel-click-left/right - +/- auto_pause_min_words. (fancy mouses)
Back-click - translate whole sentence. (fancy mouses)

Troubleshooting

Does not work at all - launch mpv in a console, then start interSubs and see if there are any errors that might indicate on missing packages and install them.
Background and subtitles are shown as solid black bars - install/launch a compositor.
May have issues working in a multi-monitor system. See the solution.
On KDE subtitles might sometimes be invisible. See the solution.
On KDE subtitles fade instead of appearing immediately. See the solution
Instead of changing system settings you may change --x11-bypass-compositor
Stuttering video during subtitles change might be solved by changing mpv's video output mpv --vo gpu.
On MacOS subtitles are not rendered on top of mpv. See a possible solution
On MacOS subtitles are not rendered on top of mpv only in fullscreen mode. See the solution
Xfce4 - subtitles do not show - https://github.com/oltodosel/interSubs/issues/54
