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.

Example

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!
