LLPlayer provides a media player for language learners with dual subtitles and playback tools.
About LLPlayer
LLPlayer is an open-source media player built for language learners, distributed as a GitHub repository. It can show two subtitles at once, generate subtitles from any video or audio with OpenAI Whisper (through the whisper.cpp or faster-whisper engines), translate subtitle text in real time using engines such as Google, DeepL, Ollama, LM Studio or OpenAI, and convert bitmap subtitles into text with Tesseract or Microsoft OCR. Context-aware translation uses an LLM to judge subtitle context, and online videos can be played back through yt-dlp integration.
The application runs on Windows 10 x64 (version 1903 or later) and Windows 11 x64, and requires the .NET Desktop Runtime 10. Microsoft Visual C++ Redistributable 2022 or later is needed for Whisper ASR and Tesseract OCR; without it the app still launches but can crash when ASR or OCR is enabled. Subtitle generation and translation depend on downloaded models and third-party engines, and Nvidia RTX users may install the CUDA Toolkit for faster subtitle generation. Pricing is not stated in the source.

LLPlayer FAQ
What operating systems does LLPlayer support?
Windows 10 x64 version 1903 or later and Windows 11 x64.
Do I need to install anything besides LLPlayer?
Yes. The .NET Desktop Runtime 10 is required, and Microsoft Visual C++ Redistributable 2022 or later is needed for Whisper ASR and Tesseract OCR. Without the redistributable, the app launches but can crash when ASR or OCR is enabled.
Can LLPlayer create subtitles for videos that have none?
Yes. It generates subtitles in real time from any video or audio using OpenAI Whisper, with the whisper.cpp and faster-whisper engines supported. Whisper models are downloaded from the Subtitles > ASR section of the settings, and larger models mean higher load and accuracy.
