# Installation
If you are running an Arch Linux based distro then you can find gpu screen recorder on aur under the name gpu-screen-recorder (`yay -S gpu-screen-recorder`).\
If you are running another distro then you can run `sudo ./install.sh`, but you need to manually install the dependencies, as described below.\
You can also install gpu screen recorder ([the gtk gui version](https://git.dec05eba.com/gpu-screen-recorder-gtk/)) from [flathub](https://flathub.org/apps/details/com.dec05eba.gpu_screen_recorder), which is the easiest method

to install GPU Screen Recorder on non-arch based distros.\
If you install GPU Screen Recorder flatpak, which is the gtk gui version then you can still run GPU Screen Recorder command line by using the flatpak command option, for example `flatpak run --command=gpu-screen-recorder com.dec05eba.gpu_screen_recorder -w screen -f 60 -o video.mp4`. Note that if you want to record your monitor on AMD/Intel then you need to install the flatpak system-wide (like so: `flatpak install flathub --system com.dec05eba.gpu_screen_recorder`).
If you install GPU Screen Recorder flatpak, which is the gtk gui version then you can still run GPU Screen Recorder command line by using the flatpak command option, for example `flatpak run --command=gpu-screen-recorder com.dec05eba.gpu_screen_recorder -w screen -f 60 -o video.mp4`.

You can use the `-replay-storage disk` option to store the replay buffer on disk instead of ram (in the same location as the output video).\
By default videos are recorded with constant quality, but with replay mode you might want to record in constant bitrate mode instead for consistent ram/disk usage in high motion scenes. You can do that by using the `-bm cbr` option (along with `-q` option, for example `-bm cbr -q 20000`).

# Issues
## NVIDIA
Nvidia drivers have an issue where CUDA breaks if CUDA is running when suspend/hibernation happens, and it remains broken until you reload the nvidia driver. `extra/gsr-nvidia.conf` will be installed by default when you install GPU Screen Recorder and that should fix this issue. If this doesn't fix the issue for you then your distro may use a different path for modprobe files. In that case you have to install that `extra/gsr-nvidia.conf` yourself into that location.
You have to reboot your computer after installing GPU Screen Recorder for the first time for the fix to have any effect.
# Examples
Look at the [scripts](https://git.dec05eba.com/gpu-screen-recorder/tree/scripts) directory for script examples. For example if you want to automatically save a recording/replay into a folder with the same name as the game you are recording.
# AMD/Intel/Wayland root permission
When recording a window or when using the `-w portal` option no special user permission is required,
however when recording a monitor the program needs root permission (to access KMS).\
This is safe in GPU Screen Recorder as the part that needs root access has been moved to its own small program that only does one thing.\
For you as a user this only means that if you installed GPU Screen Recorder as a flatpak then a prompt asking for root password will show up once when you start recording.

On a system with an AMD Ryzen 9 5900X CPU and an RX 7800XT GPU I dont see any fps drop at all, even when recording at 4k 60fps with AV1 codec with 10-bit colors.\
GPU Screen Recorder also produces much smoother videos than OBS when GPU utilization is close to 100%, see comparison here: [https://www.youtube.com/watch?v=zfj4sNVLLLg](https://www.youtube.com/watch?v=zfj4sNVLLLg) and [https://www.youtube.com/watch?v=aK67RSZw2ZQ](https://www.youtube.com/watch?v=aK67RSZw2ZQ).\

It is recommended to save the video to a SSD because of the large file size, which a slow HDD might not be fast enough to handle. Using variable framerate mode (-fm vfr) which is the default is also recommended as this reduces encoding load. Ultra quality is also overkill most of the time, very high (the default) or lower quality is usually enough.\

You can automatically add this option if you run `sudo nvidia-xconfig --cool-bits=12` and then reboot your computer.\
Note that this only works when Xorg server is running as root, and using this option will only give you a performance boost if the game you are recording is bottlenecked by your GPU.\

## TEMPORARY ISSUES
1) Videos are in variable framerate format. Use MPV to play such videos, otherwise you might experience stuttering in the video if you are using a buggy video player. You can try saving the video into a .mkv file instead as some software may have better support for .mkv files (such as kdenlive). You can use the "-fm cfr" option to to use constant framerate mode.
2) FLAC audio codec is disabled at the moment because of temporary issues.

# FAQ
## It tells me that my AMD/Intel GPU is not supported or that my GPU doesn't support h264/hevc, but that's not true!
Some linux distros (such as manjaro and fedora) disable hardware accelerated h264/hevc on AMD/Intel because of "patent license issues". If you are using an arch-based distro then you can install mesa-git instead of mesa and if you are using another distro then you may have to switch to a better distro. On fedora based distros you can follow this: [Hardware Accelerated Codec](https://rpmfusion.org/Howto/Multimedia).\
@@ -202,7 +208,9 @@ Browsers and discord don't support hevc video codec at the moment. Choose h264 v
Note that websites such as youtube support hevc so there is no need to choose h264 video codec if you intend to upload the video to youtube or if you want to play the video locally or if you intend to
edit the video with a video editor. Hevc allows for better video quality (especially at lower file sizes) so hevc (or av1) is recommended for source videos.
## I get a black bar/distorted colors on the sides in the video
This is mostly an issue on AMD. For av1 it's a hardware issue, see: https://gitlab.freedesktop.org/mesa/mesa/-/issues/9185. For hevc it's a software issue in the AMD driver that hasn't been fixed yet. This issue happens at certain video resolutions. If you get this issue then a workaround is to record with h264 video codec instead (using the -k h264 option).
This is mostly an issue on AMD. For av1 it's a hardware issue, see: https://gitlab.freedesktop.org/mesa/mesa/-/issues/9185. For hevc it's a software issue in ffmpeg that was fixed in ffmpeg version 8.\
If your ffmpeg version is older than 8 then you can use the flatpak version of GPU Screen Recorder which comes with ffmpeg version >= 8.\
Alternatively you can record with h264 codec (-k h264, which is also the default codec) to workaround this issue.

and on Wayland the external GPU will display the graphics for that monitor.

Alternatively you can capture with the desktop portal option (`-w portal`), which should allow you to capture any monitor.\
However if you really want to change which GPU you want to record and encode with with then you can instead configure your display server (Xorg or Wayland compositor) to run with that GPU,
then GPU Screen Recorder will automatically use that same GPU for recording and encoding.
## The rotation of the video is incorrect when the monitor is rotated when using desktop portal capture
This is a bug in kde plasma wayland. When using desktop portal capture and the monitor is rotated and a window is made fullscreen kde plasma wayland will give incorrect rotation to GPU Screen Recorder.
This also affects other screen recording software such as obs studio.\
Capture a monitor directly instead to workaround this issue until kde plasma devs fix it, or use another wayland compositor that doesn't have this issue.

Some desktop environments such as KDE Plasma turn off notifications when you record the screen with the desktop portal option. You can disable this by going into KDE Plasma settings -> search for notifications and then under "Do Not Disturb mode" untick "During screen sharing".

Monitor capture on steam deck is slightly below the game fps, but only when capturing on the steam deck screen. If capturing on another monitor, there is no issue.
Is this related to the dma buf rotation issue? different modifier being slow? does this always happen?
Fallback to vaapi copy in kms if opengl version fails. This can happen on steam deck for some reason (driver bug?). Also vaapi copy uses less gpu since it uses video codec unit to copy.
Test if vaapi copy version uses less memory than opengl version.
Intel is a bit weird with monitor capture and multiple monitors. If one of the monitors is rotated then all the kms will be rotated as well.
Is that only the case when the primary monitor is rotated? Also the primary monitor becomes position 0, 0 so crtc (x11 randr) position doesn't match the drm pos. Maybe get monitor position and size from drm instead.
How about if multiple monitors are rotated?

Investigate if there is a way to do gpu->gpu copy directly without touching system ram to enable video encoding on a different gpu. On nvidia this is possible with cudaMemcpyPeer, but how about from an intel/amd gpu to an nvidia gpu or the other way around or any combination of iGPU and dedicated GPU?
Maybe something with clEnqueueMigrateMemObjects? on AMD something with DirectGMA maybe?
Go back to using pure vaapi without opengl for video encoding? rotation (transpose) can be done if its done after (rgb to yuv) color conversion.

Use opengl compute shader instead of graphics shader. This might allow for better performance when games are using 100% of graphics unit which might fix issue with 100% gpu usage causing gpu screen recorder to run slow when not using vaapi to convert rgb to nv12(?).

Check if region capture works properly with fractional scaling on wayland.
Add option to specify medium/high/very high/ultra for -bm cbr as well, which should automatically pick bitrate based on resolution and framerate.
This should also be reflected in gsr ui.

Implement webcam support by using mjpeg with v4l2 and use ffmpeg mjpeg decoder.
After adding rpc, making recording while in replay/streaming work differently. Start recording should take audio as an argument, to optionally specify different audio for recording than replay/stream.
After adding rpc, make it possible to add/remove audio and video. The same number of audio tracks should remain, but the audio devices/app should be possible to configure. You should be able to configure the capture sources however you want.
It takes a while to shutdown gpu screen recorder when using replay with a long replay time (when the replay buffer is for example 6gb). Maybe this has to do with cleaning up so much memory. Try if _exit(0) is faster, ignoring cleanup of anything (assuming the gpu driver is happy with that, nvidia doesn't like such things. GPU drivers are often buggy when it comes to automatic cleanup).
Support desktop portal hdr capture when this gets merged: https://invent.kde.org/plasma/kwin/-/merge_requests/8293 note that it only works with pipewire >= 1.5.81. If codec is set to non-hdr codec when use desktop portal without hdr (convert to sdr, remove the code that forces non-hdr equivalent of the codec). Update gsr-gtk and gsr-ui accordingly.
Add option to save screenshot as .qoi. Use that then in gsr-ui for the background for the window (capture the monitor that the ui is going to show on). Do that on cosmic and hyprland, which are unable to display things behind the fullscreen window.
Support pausing recording when recording while replay/streaming.
Maybe use VK_VALVE_video_encode_rgb_conversion with vulkan encoding for shader-less rgb to yuv conversion. That would allow screen capture with no gpu processing.
Cursor sometimes doesn't have color when capturing region scaled (on kde plasma wayland at least).
Remove drm_monitor_get_display_server_data and do that work in the drm monitor query.
In gpu screen recorder --info output codec max resolutions. This allows for better error messages in ui frontends and easier and better error handling.
Set minimum fps for live stream or piping or always.
Support youtube sso.
Remove -fm content (support it but remove it from documentation and output deprecation notice when its used) and use it when using -fm vbr (which is the default option).
But first -fm content needs to be support on wayland as well, by checking if there is a difference between frames (checksum the frame content).
-fm content also needs to have a minimum fps to prevent live stream from timing out when nothing changes on the screen.
