Dependencies needed include gtk3, libx11, libxrandr, and libpulse (which, I believe, is in addition to the dependencies needed for the CLI version: glew, glfw3, cuda, ffmpeg, libxcomposite, libpulse-simple). Otherwise you’ll have to clone the repo and run the build.sh script.
Interested in trying it out? On Arch you can get it from the AUR (this is for the GUI version). recording the entire desktop requires a GPU with NvFBC support (Tesla and Quadro GPUs support this, others can be patched with nvidia-patch or nvlax).this only works on NVIDIA GPUs (Intel and AMD support are planned later down the road).Keep in mind the following caveats, at least for the time being: You could run this, for example: gpu-screen-recorder -w $(xdotool selectwindow) -c mp4 -f 60 -a "$(pactl get-default-sink).monitor" -o test_video.mp4
If you prefer a CLI-based version instead, you can do that. From here you can stream to YouTube or Twitch, record, or save a “replay” at a default duration of 30 seconds. On the GTK frontend, all you have to do is select a window (or record the entire desktop), adjust the resolution, framerate, and quality, and if you want to include audio as well just select your audio playback device from the dropdown menu. What I appreciate about this screen recorder besides the reduced CPU usage is how dead simple it is to use. The result came out pretty good! File size was fairly large at 1.5 GB (about 16 minutes of footage, so roughly 1 GB for every 10 minutes) at High quality, but I didn’t notice any slowdowns playing the game while recording. I recorded some footage of the Metroid Prime remastered mod with this. GamingOnLinux had also recently touched on this. The developer of this project claims this significantly reduces CPU usage, “at around 0%” due to keeping the window image on the GPU and sending it directly to the video encoding unit with CUDA. Introducing a new, open-source screen recorder: gpu screen recorder. But you might have noticed something while trying to record gameplay on Linux: the CPU gets taxed quite a bit, even when using the NVENC encoder on NVIDIA GPUs.
Don’t get me wrong OBS is a great tool to record your screen, regardless of what operating system your using.
