If you are running an Arch Linux based distro, then you can find gpu screen recorder on aur under the name gpu-screen-recorder-git (`yay -S gpu-screen-recorder-git`).\
If you are running an Ubuntu based distro then run `install_ubuntu.sh` as root: `sudo ./install_ubuntu.sh`.\
On other distros you need to install dependencies manually and run `build.sh`. Dependencies: `glew glfw3 ffmpeg libx11 libxcomposite libpulse-simple`. You need to additionally have `cuda` installed when you run `gpu-screen-recorder`.\
On other distros you need to install dependencies manually and run `build.sh`. Dependencies: `libgl (libglvnd), ffmpeg, libx11, libxcomposite, libpulse`. You need to additionally have `cuda` installed when you run `gpu-screen-recorder`.\
If you use a distro that isn't friendly to nvidia, such as fedora, then you can also install gpu-screen-recorder-gtk with flatpak here: [gpu-screen-recorder-flatpak](https://git.dec05eba.com/gpu-screen-recorder-flatpak/about/).\
Recording monitors requires a gpu with NvFBC support (note: this is not required when recording a single window!). Normally only tesla and quadro gpus support this, but by using [nvidia-patch](https://github.com/keylase/nvidia-patch) or [nvlax](https://github.com/illnyang/nvlax) you can do this on all gpus that support nvenc as well (gpus as old as the nvidia 600 series), provided you are not using outdated gpu drivers.

@ -2,7 +2,6 @@ Check for reparent.
Only add window to list if its the window is a topmost window.
Track window damages and only update then. That is better for output file size.
Getting the texture of a window when using a compositor is an nvidia specific limitation. When gpu-screen-recorder supports other gpus then this can be ignored.
Remove dependency on glfw (and glew?).
Quickly changing workspace and back while recording under i3 breaks the screen recorder. i3 probably unmaps windows in other workspaces.
Nvidia 515.57 supports nvfbc direct capture with mouse capture. Check if driver is equal or newer than this and use mouse capture in such situations (with direct capture) supports nvfbc direct capture with mouse capture.
See https://trac.ffmpeg.org/wiki/EncodingForStreamingSites for optimizing streaming.
