# gpu screen recorder
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.
The output is an h264 encoded video with aac audio.
This project is still early in development.
# Performance
When recording a 4k game, fps drops from 30 to 7 when using OBS Studio, however when using this screen recorder
the fps remains at 30.
# Installation
gpu screen recorder can be built using [sibs](https://github.com/DEC05EBA/sibs) or if you are running Arch Linux, then you can find it on aur under the name gpu-screen-recorder-git (`yay -S gpu-screen-recorder-git`).
# Example
Run `interactive.sh` or run `gpu-screen-recorder -w 0x1c00001 -c mp4 -f 60 -a bluez_sink.00_18_09_8A_07_93.a2dp_sink.monitor > test_video.mp4`
# Demo
[](https://www.youtube.com/watch?v=n5tm0g01n6A)
# Requirements
X11, Nvidia (cuda), alsa or pulseaudio
# TODO
* Scale video when the window is rescaled.
* Support AMD and Intel, using VAAPI. cuda and vaapi should be loaded at runtime using dlopen instead of linking to those
libraries at compile-time.
* Clean up the code!
