Watch a video (URL, local path, or SMB/UNC share) fully locally. Downloads with yt-dlp, extracts auto-scaled frames with ffmpeg, ALWAYS transcribes with faster-whisper locally and compares against creator-provided captions when present. Auto-detects an NVIDIA GPU (NVDEC decode + CUDA whisper) and falls back to CPU-only mode without one. All tools run natively from a self-provisioned portable runtime -- no Docker, no system installs. No cloud API keys.
