Detect and Use FFmpeg's QSV/NVENC/AMF Encoders

[jpyper]

I am reposting my Discussion post as an Issue now with some slight modifications. I utilized the Discussion tab. My post, #645 has gone ignored for over 2 months. Nobody reads the Discussion tab on GitHub projects. That's where posts go to pasture. :-/

I use rigaya's QSVEncC encoder only with FastFlix. I figured it might be a useful to keep everything in one place and make available FFmpeg's hardware encoders, if they are compiled in and detected. One command line for everything to simplify all encoding needs. Keep the option to use rigaya's encoders in the Settings menu if the user wants to use them as well. More is better, right? Just food for thought.

This is on a fresh install of vanilla Arch Linux as of about 2 hours ago. I don't have a Debian/Ubuntu system or any other system to test against, but Arch is well known where when you build it, it MIGHT run. Well, I guess they are off to a pretty good start by compiling in to their release of FFmpeg the basics for utilizing hardware encoding.

So, do you think you can add all available FFmpeg hardware encoders? It does show FFmpeg NVENC HEVC, which I think is forced for some reason, in the menu of available encoders, even though I do not use or own an Nvidia GPU card.

Windows counterpart commandline: ffmpeg -hide_banner -encoders | findstr /i "<argument>"

Anyway I always prefer to use @rigaya's *Encs for hardware encodings instead.
