LLEAP

stands for Language LEArning Player. It's basically a clone of Language Reactor aka Language Learning with Netflix, but it is designed to play HTTP streams or local files from your computer. Implemented using Relm4 (gtk4+libadwaita), gstreamer and ffmpeg.

Currently this is alpha-quality software with probably a good number of bugs.

Features

• can display multiple subtitle tracks concurrently
• can extract subtitles from audio using whisper-cpp
• can auto-translate subtitles using the DeepL api

Known bugs

• sometimes the file won't start playing after pressing "play"
• the program will probably behave weirdly when opening several files after each other
• something goes wrong with the URL printing/parsing when opening files with mildly funny characters (whitespace?)

TODOs

• make whisper model path, maybe also other arguments configurable
• implement key bindings
• specify source language in deepl api calls
• make target language for machine translation configurable
• implement dictionary lookup for single words
• allow specifying file/url on the conmmand line

Wishlist

• LLM integration for grammar explanations etc
