okay bestie so you found the mp4file page 💖 it lives in the MP4v2 Utilities fam, section 1, and it's the manual page for mp4file trunk-r507. sit down, grab a strawberry 🍓, we're doing this.

✨ SYNOPSIS ✨

mp4file [OPTION]... ACTION file...

💅 DESCRIPTION 💅

For each mp4 file you name, it performs the ACTION you picked. An action must be specified — like, non-negotiable, the program will simply not know what you want from it. Also, some options are just not applicable to some actions. it's giving picky, and honestly? valid.

🎀 ACTIONS 🎀

  • --list — list, i.e. summary information. the lil overview moment ✨
  • --optimize — optimize mp4 structure. glow-up for your file's layout 💖
  • --dump — dump mp4 structure in human-readable format. everything, laid bare, no secrets 🙈

👑 OPTIONS 👑

  • -y, --dryrun — do not actually create or modify any files. pure vibes, zero consequences 🦋
  • -k, --keepgoing — continue batch processing even after errors. she does not stop for drama 💅
  • -q, --quiet — equivalent to --verbose 0. shhh mode 🤫
  • -d, --debug NUM — increase debug, or as a long-option, set NUM directly. 👀
  • -v, --verbose NUM — increase verbosity, or as a long-option, set NUM directly. she's chatty fr fr
  • -h, --help — print brief help, or as a long-option, get extended help. the classic 🫶
  • --version — print version information and exit. bye bestie 👋

🧚 DEBUG LEVELS (for raw mp4 file I/O) 🧚

  • 0 — supressed 🙈 (yes that's how they spelled it, we respect the lore)
  • 1 — add warnings and errors (default)
  • 2 — add table details
  • 3 — add implicits
  • 4 — everything 🔥

🌈 VERBOSE LEVELS 🌈

  • 0 — warnings and errors
  • 1 — normal informative messages (default) ✨
  • 2 — more informative messages
  • 3 — everything 💀
lowkey the whole point: pick an ACTION, feed her some files, and let the options set the vibe check. no cap.
