# 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.
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 0x1c00001 mp4 60 > test_video.mp4`
# Requirements
X11, Nvidia (cuda)
# TODO
* Scale video when the window is rescaled.
* Use the sound source in src/sound.cpp to record audio and mux it with ffmpeg to the final video.
* 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!
