Requirements, SBLive, gtx 600, 700 or 900 series, FFmpeg compiled with nvenc [x264 works as well, but needs more power], Twitch account. [to be done later]

(other cards than sblive works, but sblive can record from hw:0 and record sound from output and hw:0,2 is a special mic device for mumble/discord [note: u don't need it if you use TeamSpeak])

        playback.pcm {
                type plug
                slave.pcm "hw:0,0"

Bugs: ezquake 3 will get 125hz mice when recording.
