# 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!
