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 is the fastest screen recording tool for Linux. This screen recorder only works on X11 (Wayland with Xwayland is NOT supported).
This screen recorder can be used for recording your desktop offline, for live streaming and for nvidia-like instant replay, where only the last few seconds are saved.
There are some restrictions when recording on AMD/Intel. Videos created on AMD/Intel are in variable framerate format. Very out of date video players might have an issue playing such videos. I recommend using MPV or a browser to play such videos, otherwise you might experience stuttering in the video. Recording a monitor requires (restricted) root access which means that you have to install GPU Screen Recorder system-wide: flatpak install flathub --system com.dec05eba.gpu_screen_recorder and pkexec needs to be installed on the system. Some distros such as manjaro disable hardware accelerated H264/HEVC which means GPU Screen Recorder wont work on AMD/Intel and you have to either switch to another distro or install mesa from source (or install mesa-git for example).
Attempt to fix possible issue on some systems with amd/intel where capture region is incorrect when multiple monitors are connected.
Attempt to fix possible audio/video sync on NVIDIA after recording for a long time. Temporary disable opus/flac because it breaks when recording multiple audio inputs.
AMD/Intel: Add support for capturing cursor when recording a monitor. Fix some cases of capture being glitched when using multiple monitors.
Enable AMD/Intel monitor capture. Requires the flatpak to be installed system-wide and it requires restricted root access. Record a single window if you dont like these restrictions. Videos created on AMD/Intel should be played with MPV otherwise it might have issues such as stuttering.
Add experimental support for AMD/Intel. Quality might not be well tuned yet and the video is in variable framerate mode, which might cause issues with some out of date video editing software or video players. Recording on AMD/intel is currently limited to a window (monitor capture is not possible yet).
Show error when using wayland (because wayland is not supported)
Add option to workaround a NVIDIA driver "bug" that causes framerate to drop a bit when recording (overclock memory transfer rate back to normal)
Make it clear when graphics card is not supported
Fix broken replay when recording with audio (possibly broken in normal recording as well)
Allow choosing between mp4, flv and mkv for record/replay. mkv survives system crashes
Re-enable screen-direct, disable h264 forced fallback and use p6 again
Attempt to fix stuttering in video that can happen sometimes (especially when vsync is enabled)
Properly fallback to h264 if hevc is not supported by the gpu
Fix livestreaming: flv does not properly fallback to h264
Use lower preset on older gpus (kepler) and switch to h264 if h265 is not supported
Tune options to try and reduce file size
Better tune quality options for different resolutions
Fix crash caused by invalid memory write when recording audio
Fix possible pulseaudio crash
Fixes some streaming issues (mostly metadata missing)
