gtk frontend for [gpu-screen-recorder](https://git.dec05eba.com/gpu-screen-recorder/about/).

This is a screen recorder that has minimal impact on system performance by recording a window using the GPU only,
similar to shadowplay on windows. This is the fastest screen recording tool for Linux.

This screen recorder can be used for recording your desktop offline, for live streaming and for nvidia shadowplay-like instant replay,
where only the last few seconds are saved.

## Note
This software works with x11 and wayland, but when using wayland only monitors can be recorded and root access is needed.
### TEMPORARY ISSUES
1) Recording the monitor on steam deck might fail sometimes. This happens even when using ffmpeg directly. This might be a steam deck driver bug. Recording a single window doesn't have this issue.
2) Videos created on AMD/Intel are in variable framerate format. Use MPV to play such videos, otherwise you might experience stuttering in the video if you are using a buggy video player. Try saving the video into a .mkv file instead when using AMD/Intel, as some software may have better support for .mkv files (such as kdenlive).
# Performance
On a system with a i5 4690k CPU and a GTX 1080 GPU:\
When recording Legend of Zelda Breath of the Wild at 4k, fps drops from 30 to 7 when using OBS Studio + nvenc, however when using this screen recorder the fps remains at 30.\
When recording GTA V at 4k on highest settings, fps drops from 60 to 23 when using obs-nvfbc + nvenc, however when using this screen recorder the fps only drops to 58. The quality is also much better when using gpu-screen-recorder.\
It is recommended to save the video to a SSD because of the large file size, which a slow HDD might not be fast enough to handle.\
Note that if you have a very powerful CPU and a not so powerful GPU and play a game that is bottlenecked by your GPU and barely uses your CPU then a CPU based screen recording (such as OBS with libx264 instead of nvenc) might perform slightly better than GPU Screen Recorder. At least on NVIDIA.
## Note about optimal performance on NVIDIA
NVIDIA driver has a "feature" (read: bug) where it will downclock memory transfer rate when a program uses cuda (or nvenc, which uses cuda), such as GPU Screen Recorder. See https://git.dec05eba.com/gpu-screen-recorder/about/ for more information and how to overcome this.
## Note about optimal performance on AMD/Intel
Performance is the same when recording a single window or the monitor, however in some cases, such as when gpu usage is 100%, the video capture rate might be slower than the games fps when recording a single window instead of a monitor. Recording the monitor instead is recommended in such cases.

## Installation
This program depends on [gpu-screen-recorder](https://git.dec05eba.com/gpu-screen-recorder/) which needs to be installed first.\
Run `sudo ./install.sh` or if you are running Arch Linux, then you can find gpu screen recorder gtk on aur under the name gpu-screen-recorder-gtk-git (`yay -S gpu-screen-recorder-gtk-git`).\
Dependencies needed when building using `build.sh` or `install.sh`: `gtk3 libx11 libxrandr libpulse libdrm wayland-client`.\
You can also install gpu screen recorder (the gtk gui version) from [flathub](https://flathub.org/apps/details/com.dec05eba.gpu_screen_recorder). This flatpak includes gpu-screen-recorder so no need to install that first.\
Note that if you use the flatpak version then you wont be able to use overclocking unless you set "Coolbits" NVIDIA X setting. See https://git.dec05eba.com/gpu-screen-recorder/about/ for more information and how to overcome this.
