* feat: add YouTube design concept extractor tool Extracts transcript, metadata, and keyframes from YouTube videos into a structured markdown reference document for agent consumption. Supports interval-based frame capture, scene-change detection, and chapter-aware transcript grouping. https://claude.ai/code/session_01KZxeSK9A2F2oZUoHgxUUBV * feat: add OCR and color palette extraction to yt-design-extractor - Add --ocr flag with Tesseract (fast) or EasyOCR (stylized text) engines - Add --colors flag for dominant color palette extraction via ColorThief - Add --full convenience flag to enable all extraction features - Include OCR text alongside each frame in markdown output - Add Visual Text Index section for searchable on-screen text - Export ocr-results.json and color-palette.json for reuse - Run OCR in parallel with ThreadPoolExecutor for performance https://claude.ai/code/session_01KZxeSK9A2F2oZUoHgxUUBV * feat: add requirements.txt and Makefile for yt-design-extractor - requirements.txt with core and optional dependencies - Makefile with install, deps check, and run targets - Support for make run-full, run-ocr, run-transcript variants - Cross-platform install-ocr target (apt/brew/dnf) https://claude.ai/code/session_01KZxeSK9A2F2oZUoHgxUUBV * chore: move Makefile to project root for easier access Now `make install-full` works from anywhere in the project. https://claude.ai/code/session_01KZxeSK9A2F2oZUoHgxUUBV * fix: make easyocr truly optional, fix install targets - Remove easyocr from install-full (requires PyTorch, causes conflicts) - Add separate install-easyocr target with CPU PyTorch from official index - Update requirements.txt with clear instructions for optional easyocr - Improve make deps output with clearer status messages https://claude.ai/code/session_01KZxeSK9A2F2oZUoHgxUUBV * fix: harden error handling and fix silent failures in yt-design-extractor - Check ffmpeg return codes instead of silently producing 0 frames - Add upfront shutil.which() checks for yt-dlp and ffmpeg - Narrow broad except Exception catches (transcript, OCR, color) - Log OCR errors instead of embedding error strings in output data - Handle subprocess.TimeoutExpired on all subprocess calls - Wrap video processing in try/finally for reliable cleanup - Error on missing easyocr when explicitly requested (no silent fallback) - Fix docstrings: 720p fallback, parallel OCR, chunk duration, deps - Split pytesseract/Pillow imports for clearer missing-dep messages - Add run-transcript to Makefile .PHONY and help target - Fix variable shadowing in round_color (step -> bucket_size) - Handle json.JSONDecodeError from yt-dlp metadata - Format with ruff --------- Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: Seth Hobson <wshobson@gmail.com>
