# Installation
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`.\
If you are running an Ubuntu based distro then run `install_ubuntu.sh` as root: `sudo ./install_ubuntu.sh`. You also need to install the `libnvidia-compute` version that fits your nvidia driver to install libcuda.so to run gpu-screen-recorder.\
If you are running another distro then you can run `install.sh` as root: `sudo ./install.sh`, but you need to manually install the dependencies, as described below.\
You can also install gpu screen recorder ([the gtk gui version](https://git.dec05eba.com/gpu-screen-recorder-gtk/)) from [flathub](https://flathub.org/apps/details/com.dec05eba.gpu_screen_recorder).
# Dependencies
`libgl (libglvnd), ffmpeg, libx11, libxcomposite, libpulse`. You need to additionally have `cuda` installed when you run `gpu-screen-recorder`.\

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can do this on all gpus that support nvenc as well (gpus as old as the nvidia 600 series), provided you are not using outdated gpu drivers.

@ -13,3 +13,4 @@ Allow recording a region by recording the compositor proxy window / nvfbc window
Resizing the target window to be smaller than the initial size is buggy. The window texture ends up duplicated in the video.
Handle frames (especially for applications with rounded client-side decorations, such as gnome applications. They are huge).
Use nvenc directly, which allows removing the use of cuda.
Fallback to nvfbc and window tracking if window capture fails.
