Merged
Conversation
- Add paddle_ocr.py wrapper for PaddleOCR - Add ocr.rs with ocr_recognize and ocr_get_languages commands - Update mod.rs to include ocr module - Update lib.rs to register OCR commands - Update system.rs to check PaddleOCR dependency Refs: Task 1.1 of optimization plan
- Add GPU detection in paddle_ocr.py (auto-enable CUDA when available) - Create Rust gpu.rs command to check GPU capability via PaddlePaddle - Register check_gpu_capability in Tauri invoke handler - Create useGPU.ts Vue composable for frontend GPU detection - Add GPU info section to Settings.vue (shows only when GPU available) - Update ocr.rs to handle new JSON response format with GPU info
- Add Translator class supporting Google Translate, DeepL, and OpenAI - Add useBilingual composable for translation workflow - Add translatedText field to SubtitleItem type - Add exportBilingualSRT and exportBilingualVTT functions - Add translation UI to Export tab with provider/language settings
P0: Replace Python dependencies with Rust native implementations: - scene.rs: PySceneDetect → FFmpeg 'select' filter (4.4-5.3x faster) - auto_roi.rs: OpenCV → Rust 'image' crate Sobel edge detection (8.4x faster) - Deleted scene_detect.py and auto_detect_roi.py - Added standalone_tests.rs (18 pure-logic tests) - Added BENCHMARKS.md with performance comparison - Fixed deduplicate_timestamps boundary condition ('<' → '<=') P1: Store refactoring: - Split project.ts → video.ts + extraction.ts - project.ts kept as deprecated backward-compat facade - All 410 JS tests pass, 19 test files green
