[Cin] random console ffmpeg prog

I was looking for this mess of hw encoders on ARM singleborad computers and randomly hit this blog: https://www.willusher.io/general/2020/11/15/hw-accel-encoding-rpi4 so apparently default 'OS' on Pi4 uses v4ĺ2 encoder, should be easy to create profile for (just copy vaapi one and edit ) and as bonus you can find python + ffmpeg encoding manager .... another random project is wayland capture program, might not work on intel due to fb modifiers (?) https://trac.ffmpeg.org/ticket/8542 https://github.com/cyanreg/txproto and all this because adventurious user 'goat' reported he had better luck with cin-gg on arm single-board computer under Wayland/Xwayland - namely timeline scrolling performance.
