let gsr choose video codec automatically for us when using auto (prefer h264, then hevc and then av1),
fallback to software encoding in gsr ui if none of them are available.

 A fullscreen overlay UI for [GPU Screen Recorder](https://git.dec05eba.com/gpu-screen-recorder/about/) in the style of ShadowPlay.\
 The application is currently primarly designed for X11 but it can run on Wayland as well through XWayland, with some caveats because of Wayland limitations.
 
-# Usage
-You can start the overlay UI and make it start automatically on system startup by running `systemctl enable --now --user gpu-screen-recorder-ui`.
-Alternatively you can run `gsr-ui` and go into settings and enable start on system startup setting.\
-Press `Left Alt+Z` to show/hide the UI. Go into settings to view all of the different hotkeys configured.\
-If you use a non-systemd distro and want to start the UI on system startup then you have to manually add `gsr-ui` to your system startup script.\
-A program called `gsr-ui-cli` is also installed when installing this software. This can be used to remotely control the UI. Run `gsr-ui-cli --help` to list the available commands.

 # Installation
 If you are using an Arch Linux based distro then you can find gpu screen recorder ui on aur under the name gpu-screen-recorder-ui (`yay -S gpu-screen-recorder-ui`).\
 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 from [flathub](https://flathub.org/apps/details/com.dec05eba.gpu_screen_recorder). This flatpak includes both this UI and gpu-screen-recorder so no need to install that first.
+You can also install gpu screen recorder from [flathub](https://flathub.org/apps/details/com.dec05eba.gpu_screen_recorder) which includes this UI.

+This might cause issues for you if you use keyboard remapping software. To workaround this you can go into settings and select "Yes, but only grab virtual devices" or "Yes, but don't grab devices".\
 If you use keyboard remapping software such as keyd then make sure to make it ignore "gsr-ui virtual keyboard" (dec0:5eba device id), otherwise your keyboard can get locked
 as gpu screen recorder tries to grab keys and keyd grabs gpu screen recorder, leading to a lock.\
 If you are stuck in such a lock where you cant press and keyboard keys you can press (left) ctrl+shift+alt+esc to close gpu screen recorder and remove it from system startup.

 # FAQ
 ## I get an error when trying to start the gpu-screen-recorder-ui.service systemd service
 If you have previously used the flatpak version of GPU Screen Recorder with the new UI then the non-flatpak version of the systemd service will conflict with that. Run `gsr-ui` to fix that.
+## I use a non-qwerty keyboard layout and I have an issue with incorrect keys registered in the software
+This is a KDE Plasma Wayland issue. Use `setxkbmap <language>` command, for example `setxkbmap se` to make sure X11 applications (such as this one) gets updated to use your languages keyboard layout.
+## "Save to clipboard" option doesn't work for screenshots
+Some Wayland compositors don't support copying images on the clipboard between X11 and Wayland applications. GPU Screen Recorder UI is an X11 application. It can't be done properly on Wayland
+since Wayland doesn't support a non-focused application from setting the clipboard, so it can't work with GPU Screen Recorder hotkey usage. Use X11 if you want a functioning desktop.
+## The controller hotkey and steam overlap (home button brings up steam overlay)
+You can either disable the steam overlay or in steam click Steam->Settings->Controller and then click "Begin Test" under "Test Device Inputs". Click on "Setup Device Inputs" and configure controller buttons there and when you get to the home button press X to unbind it from steam.

+    show a tooltip that says that those buttons cant be used because the replay duration in replay settings is set to a lower value than that (and display the replay duration there).
+
+The UI is unusable on a vertical monitor.
+
+Steam overlay interfers with controller input in gsr ui. Maybe move controller handling the gsr-global-hotkeys to do a grab on the controller, to only give the key input to gsr ui.
+
+For joysticks (gamepads) create a virtual device for each one (/dev/uinput) that has the same vendor, product and name. This is to make sure that it behaves the same way in applications since applications
+    access joysticks directly through /dev/input/eventN or /dev/input/jsN. It needs the same number of buttons and pretend to be a controller of the same time, for example a ps4 controller
+    so that games automatically display ps4 buttons if supported.
+    This also allows us to copy event bits and other data from the device instead of saying we support everything.
+    This should fix the issue of not being able to write to /dev/uinput with ABS_X event bit set.
+    Maybe do this for regular keyboard inputs as well?
+
+Use generic icons for controller input in settings and allow configuring them.
+
+Add option to include game name in file name (video and screenshot). Replace / with space.
+
+Check if the focused window is on top on x11 when choosing to take screenshot or show the window as the background of the overlay.
+
+Convert clipboard image to requested type (from jpg to png for example).
+
+Save clipboard image with wayland on wayland. Some wayland compositors (such as hyprland, budgie and maybe more (wlroots based ones?)) don't support copying clipboard image data from x11 applications to wayland applications.
+    This can be done because retarded wayland only supports setting clipboard when the application has focus. This doesn't work with hotkey screenshot use.
+    This is specifically an issue when using wl_data_device_manager, which is a standard protocol. It can be done when using wlr specific protocol.
+
+When gsr supports pausing recording done in replay/streaming session then add support for that in gsr-ui as well.
+
+Add recording timer when recording to show for how long we have been recording for. Maybe the same for live streaming and replay.
+
+Add option to trim video in the ui. Show a list of all videos recorded so you dont have to navigate to them (maybe add option to manually navigate to a video as well). Maybe use mpv to view it (embedded) in the ui and trim regions (multiple) and ffmpeg command to trim it.
+
+Show the currently recorded capture in the ui, to preview if everything looks ok. This is also good for webcam overlay. Do this when gsr supports rpc, which would also include an option to get a fd to the capture texture.
+
+Show a question mark beside options. When hovering the question mark show a tooltip that explains the options.
+
+Remove all mgl::Clock usage in Overlay. We only need to get the time once per update in Overlay::handle_events. Also get time in other places outside handle_events.
+
+Handle stopping replay/stream when recording is running (show notification that the video is saved and move the video to folder with game name).
+
+Support translations.

+# Conflict with other keyboard software
+Some keyboard remapping software such as keyd may conflict with gsr-global-hotkeys if configured incorrect (if it's configured to grab all devices, including gsr-ui virtual keyboard).
+If that happens it may grab gsr-ui-virtual keyboard while gsr-global-hotkeys will grab the keyboard remapping software virtual device, leading to a circular lock, making it not possible
+to use your keyboard. gsr-global-hotkeys detects this and outputs `gsr-ui-virtual-keyboard-grabbed` to stdout. You can listen to this and stop gsr-global-hotkeys or restart it with `--no-grab`
+option to only listen to devices, not grabbing them.
