85 battle-tested ffmpeg commands devs actually Google at 2am — conversion, compression, GIFs, trimming, screen capture, streaming, subtitles, debugging. Every recipe has a plain-English note. Search it, copy it, ship it.
The same treatment as this page, applied to everything else you run at 2am: kubectl, Docker, systemd, iptables/nftables, SSH, git surgery, disk & network triage, curl, tmux — 150+ verified commands in one dense, copy-paste document (≈40 pages), organized by incident type ("pod won't start", "disk full", "port open but unreachable").
