Field notes

MediaOnDeck parses ISOBMFF structures from MP4-family files in the browser, then exposes both frame-level metadata and lower-level encoding details. Its documented views include ftyp/moov/trak/stbl box hierarchies, sample byte offsets, PTS and DTS values, I/P/B classification, QP heatmaps, motion-vector overlays, and hexadecimal bitstream navigation. The stated codec coverage is H.264/AVC and H.265/HEVC, with audio tracks listed for basic information.
