`libglvnd (which provides libgl and libegl), ffmpeg (libavcodec, libavformat, libavutil, libswresample, libavfilter), libx11, libxcomposite, libxrandr, libpulse, cuda (libnvidia-compute), nvenc (libnvidia-encode)`. Additionally, you need to have `nvfbc (libnvidia-fbc1)` installed when using nvfbc and `xnvctrl (libxnvctrl0)` when using the `-oc` option.
# How to use
Run `scripts/interactive.sh` or run gpu-screen-recorder directly, for example: `gpu-screen-recorder -w $(xdotool selectwindow) -c mp4 -f 60 -a "$(pactl get-default-sink).monitor" -o test_video.mp4` then stop the screen recorder with Ctrl+C, which will also save the recording. You can change -w to -w screen if you want to record all monitors or if you want to record a specific monitor then you can use -w monitor-name, for example -w HDMI-0 (use xrandr command to find the name of your monitor. The name can also be found in your desktop environments display settings).\

fix yuv444 for hevc.

Re-enable yuv444.
Support 10 bit output because of better gradients. May even be smaller file size. Better supported on hevc (not supported at all on h264 on my gpu).
Add nvidia/(amd/intel) specific install script for ubuntu. User should run install_ubuntu.sh but it should run different install dep script depending on if /proc/driver/nvidia/version exists or not. But what about switchable graphics setup?
Test different combinations of switchable graphics. Intel hybrid mode (running intel but possible to run specific applications with prime-run), running pure intel. Detect switchable graphics.
