The Genesis of a Universal Video Transcoder
summary
A distributed pipeline that converts proprietary surveillance files to H.264 for forensic use, built by combining screen capture automation with blind reverse engineering of hex file structures and direct decoding via FFmpeg APIs. Uses Tesseract OCR for burned-in timestamps, pixel‑color probing and click verification when automation IDs are absent, and reinstantiates decoders per chunk to survive corrupt frames. Export buttons speed up work when available; encryption or undocumented four‑byte boxes block direct transcoding.
