Premium Live Caption Player
Realtime,completely offline video subtitle generatorfor VLC.
Generate highly accurate, real-time subtitles for VLC and MPV completely offline. Powered by PySide6 and a local Vosk API acoustic engine. No internet required, zero bandwidth usage, and 100% data privacy. Calibration sliders included for perfect audio sync.
Hello hunters! 👋
I built Premium Live Caption Player because I wanted an accessible, privacy-first way to watch videos with subtitles without relying on cloud-based APIs that harvest audio data.
It pairs a native hardware-accelerated PySide6 (Qt6 Python) desktop GUI with a local Vosk neural network language model (~45MB English acoustic matrix). It listens to your system audio pipe, hooks into VLC/MPV playhead timestamps via a local websocket, and generates captions on-the-fly directly on your CPU.
Key Features:
🔒 100% Offline Privacy: Your audio never leaves your machine. No APIs or internet required.
🎛️ Manual Calibration Sliders: Easily fine-tune timing offsets to perfectly align text with voice.
⚙️ Lightweight IPC Host: Runs seamlessly in the background on Windows, Mac, and Linux.
I would love to hear your feedback on the interface, performance, and accuracy!
