ffmpeg

I have never met anyone who truly understands ffmpeg's options. I certainly don't.

You search Stack Overflow for what you need. You copy the command. It works. You don't dig deeper. Every engineer on earth does this. And still the thing runs. Transcoding video, converting audio, extracting thumbnails. One command handles nearly everything multimedia can throw at it.

Fabrice Bellard started the project in 2000. He also wrote QEMU. One person built two pieces of internet infrastructure. I have to wonder what kind of brain that takes.

The history of codecs tracks with ffmpeg. H.264 became the standard. Google countered with VP8, then VP9. H.265 got mired in licensing disputes. AV1 raised the royalty-free flag. No matter which faction won, ffmpeg quietly absorbed the new decoder. Swiss neutrality.

Licensing is a mess. ffmpeg itself is LGPL. Link in x264 and it becomes GPL. Ship it commercially and you'd better choose your build flags with care. Companies distributing GPL binaries without knowing it — they're still out there.

YouTube. Netflix. Spotify. Finding a major service that doesn't run ffmpeg somewhere underneath is harder than finding one that does. Yet nobody knows the name. That's what infrastructure means. But once in a while, I want to say its name.
