I love software that just does what it’s supposed to do and is so good at it that it’s an underpinning for other projects.

FFmpeg, curl, nmap, et., al.

What's the story with VAAPI AV1 encoding? Does it exist anywhere or not yet?

Fun fact of the day: ffmpeg is written by Fabrice Bellard, who among other impressive things, wrote the JS PC emulator capable of running windows 2000 in a browser over 10 years ago that got me fascinated with emulators in general.

It is such a swiss knife kind of tool, there's just almost nothing it can't do when it comes to video, audio and image modifications.

I wonder how many big companies uses it "in secret" that we don't know off, or distributes it with mentions buried deep underneath usage agreement.

Google must be using it for Youtube. Wikimedia is using it as well.

He also wrote QEMU, which is probably far more impressive.

I believe it is embedded in Chromium as well.
