@wolf480pl Yeah, because those beasts are more related to OS or video players.
It makes sense to just reuse existing code for this because it's huge.

But there's sustainability to take into question. If ffmpeg didn't exists (or wasn't as good) and you'd have to fork a full blown video player, then it would be an horrible task.

And this is why to me Mozilla throwing reusability of Firefox's engine is so disgusting. (And to me Chromium forks by small teams is just a way to burn developers)
