mpv-open-imdb-page | https://github.com/ctlaltdefeat/mpv-open-imdb-page

This mpv script opens the IMDb page that corresponds to the currently playing media file,
whether a film or a specific TV episode.

This script requires open-imdb-page.py to be in the same directory.
The directory should be placed inside the script folder of mpv's configuration.

Requires Python 3 and the following pip packages:
guessit
cinemagoer

Assigns the script-binding launch-imdb as Ctrl+i
