Experimental ffmpeg-vaapi plugin

[scurrvy2020]

GloriousEggroll, thanks so much for this. I compiled the latest release with your patch and it works great on my intel machine. However, I'm having problems with my HD7770 (AMD southern islands) GPU. I have many dropped frames and it takes about 2 minutes to stop recording a 10 second screen capture.

I'd be grateful if you have any tips.

edit: I forgot to mention that I am on ubuntu 18.04 with 4.15 kernel, oibaf xorg updates, standard repo ffmpeg (ffmpeg -hwaccels lists vaapi).

Dear GloriousEggroll,
thank you very much for your work! I'll try out tonight if Intel GPU and my RX 480 will succeed.

In addition: Can we expect this to be merged to mainline OBS any time soon? Is there already a pull request you could link here?
