# 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-git (`yay -S gpu-screen-recorder-git`).\
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.\
The only official ways to install GPU Screen Recorder is either from source, AUR or flathub. If you install GPU Screen Recorder from somewhere else and have an issue then try installing it
from one of the official sources before reporting it as an issue.
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`).
## Unofficial install methods
The only official ways to install GPU Screen Recorder is either from source, AUR or flathub. Other sources may be out of date and missing features or may not work correctly.\
If you install GPU Screen Recorder from somewhere else and have an issue then try installing it from one of the official sources before reporting it as an issue.\
If you still prefer to install GPU Screen Recorder with a package manager instead of from source or as a flatpak then you may be able to find a package for your distro.\
Here are some known unofficial packages:
* Debian/Ubuntu: [Pacstall](https://pacstall.dev/packages/gpu-screen-recorder)
* Nix: [NixOS wiki](https://wiki.nixos.org/wiki/Gpu-screen-recorder)

There is also a new alternative UI for GPU Screen Recorder in the style of ShadowPlay called [GPU Screen Recorder UI](https://git.dec05eba.com/gpu-screen-recorder-ui/).
## Recording
Here is an example of how to record your monitor and the default audio output: `gpu-screen-recorder -w screen -f 60 -a default_output -o ~/Videos/test_video.mp4`.
Yyou can stop and save the recording with `Ctrl+C` or by running `killall -SIGINT gpu-screen-recorder`.
You can see a list of monitor names to record if you use an invalid monitor name, for example: `gpu-screen-recorder -w invalid -f 60 -o video.mp4`.
You can see a list of capture options to record if you run `gpu-screen-recorder --list-capture-options`. This will list possible capture options and monitor names, for example:\
```
window
DP-1|1920x1080
```
in this case you could record a window or a monitor with the name `DP-1`.
## Streaming
Streaming works the same as recording, but the `-o` argument should be path to the live streaming service you want to use (including your live streaming key). Take a look at `scripts/twitch-stream.sh` to see an example of how to stream to twitch.
## Replay mode

To save a video in replay mode, you need to send signal SIGUSR1 to gpu screen recorder. You can do this by running `killall -SIGUSR1 gpu-screen-recorder`.\
To stop recording send SIGINT to gpu screen recorder. You can do this by running `killall -SIGINT gpu-screen-recorder` or pressing `Ctrl-C` in the terminal that runs gpu screen recorder. When recording a regular non-replay video this will also save the video.\
To pause/unpause recording send SIGUSR2 to gpu screen recorder. You can do this by running `killall -SIGUSR2 gpu-screen-recorder`. This is only applicable and useful when recording (not streaming nor replay).\
## Finding audio device name
You can find the default output audio device (headset, speakers (in other words, desktop audio)) with the command `pactl get-default-sink`. Add `monitor` to the end of that to use that as an audio input in gpu screen recorder.\
You can find the default input audio device (microphone) with the command `pactl get-default-source`. This input should not have `monitor` added to the end when used in gpu screen recorder.\
Example of recording both desktop audio and microphone: `gpu-screen-recorder -w screen -f 60 -a "$(pactl get-default-sink).monitor" -a "$(pactl get-default-source)" -o ~/Videos/test_video.mp4`.\
A name (that is visible to pipewire) can be given to an audio input device by prefixing the audio input with `<name>/`, for example `dummy/$(pactl get-default-sink).monitor`.\
Note that if you use multiple audio inputs then they are each recorded into separate audio tracks in the video file. If you want to merge multiple audio inputs into one audio track then separate the audio inputs by "|" in one -a argument,
for example `-a "$(pactl get-default-sink).monitor|$(pactl get-default-source)"`.
There is also a gui for the gpu screen recorder called [gpu-screen-recorder-gtk](https://git.dec05eba.com/gpu-screen-recorder-gtk/).
## Simple way to run replay without gui
Run the script `scripts/start-replay.sh` to start replay and then `scripts/save-replay.sh` to save a replay and `scripts/stop-replay.sh` to stop the replay. The videos are saved to `$HOME/Videos`.

Add 10-bit capture option. This is good because it reduces banding and quality in very dark areas while reducing the file size compared to doing the same thing with 8-bits.
Enable b-frames.
Support vfr matching games exact fps all the time. On x11 use damage tracking, on wayland? maybe there is drm plane damage tracking. But that may not be accurate as the compositor may update it every monitor hz anyways. On wayland maybe only support it for desktop portal + pipewire capture.
@@ -178,4 +174,24 @@ Support ROI (AV_FRAME_DATA_REGIONS_OF_INTEREST).
Default to hevc if capture size is larger than 4096 in width or height.
Set low latency mode on vulkan encoding.
Set low latency mode on vulkan encoding.
Support recording/replay/livestreaming at the same time by allowing commands to be run on an existing gpu screen recorder instance.
Test if `xrandr --output DP-1 --scale 1.5` captures correct size on nvidia.
Fix cursor position and scale when scaling x11 display.
Support surround audio in application audio recording. Right now only stereo sound is supported.
Support application audio recording without pulseaudio combined sink.
Support transposing (rotating) with vaapi. This isn't supported on many devices with rgb buffer, but its supported with nv12 buffer (on intel at least).
Cleanup pipewire_audio.c (proper error handling and memory cleanup of proxies).
Hide application audio module-null-sink by using sink_properties=media.class="Audio/Sink/Internal".
Improve software encoding performance.
Add option to record audio from the recorded window only.
