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 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

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!
