cause silent errors. Anytime you alter these settings, watch the output of: 
`obs | grep -i failed`
 ** background notes: man ffmpeg-codecs says -g is group of picture size, but 
online sources call it the "keyframe interval."  In vp9, at roughly > 2 seconds 
worth of frames, it starts to increase latency at a corresponding rate. If cpu 
struggles, adjust cpu-used upward, max is 8 which uses the lowest cpu.
 * Audio Bitrate: `96 Kbps`
 * Audio Track: check mark on 1.
