Elegantly record your screen

Capture your screen in a intuitive and straightforward way without distractions.

Kooha is a simple screen recorder with a minimal interface. You can simply click the record button without having to configure a bunch of settings.

The main features of Kooha include the following:

• 🎥 Capture your screen without any hassle.
• 🎙️ Record your microphone, computer sounds, or both at the same time.
• 📼 Support for WebM, MP4, GIF, and MKV formats.
• 🗔 Multiple sources selection.
• 🚀 Optional hardware accelerated encoding
• 🖥️ Select a monitor or window to record.
• 🔲 Create a selection to capture certain area from your screen.
• ⏲️ Set delay to prepare before you start recording.
• 🖱️ Hide or show mouse pointer.
• 💾 Choose a saving location for your recording.
• ⌨️ Utilize helpful keyboard shortcuts.

There are many possibilities on why it may not be working. You may not have the runtime requirements mentioned below installed, or your distro doesn't support it. For troubleshooting purposes the screen cast compatibility page of xdg-desktop-portal-wlr wiki may be helpful in determining if your distro has support for it out of the box. If it does, but it still doesn't work, you can also check for the troubleshooting checklist.

Enabling hardware accelerated encoding allows the encoder to utilize GPU for more efficient or perhaps faster encoding. It is not guaranteed to work on all devices, so it may give errors such as no element vaapivp8enc depending on the features and capability of your hardware.

To enable all the supported drivers and force Kooha to use VAAPI elements, set GST_VAAPI_ALL_DRIVERS and KOOHA_VAAPI both to 1 respectively. These environment variables are needed for hardware accelerated encoding.

To run Kooha with both set, run the following command:

GST_VAAPI_ALL_DRIVERS=1 KOOHA_VAAPI=1 flatpak run io.github.seadve.Kooha

or if installed locally, run

GST_VAAPI_ALL_DRIVERS=1 KOOHA_VAAPI=1 kooha

Take note that using other frames per second may cause flickering, depending on the performance of your device.

You can copy and paste this to the terminal if you installed Kooha as a flatpak:

flatpak run --command=gsettings io.github.seadve.Kooha set io.github.seadve.Kooha video-frames 60

or if installed locally, run

gsettings set io.github.seadve.Kooha video-frames 60

• gstreamer-plugin-pipewire
• xdg-desktop-portal
• xdg-desktop-portal-(e.g., gtk, kde, wlr)

GNOME Builder is the environment used for developing this application. It can use Flatpak manifests to create a consistent building and running environment cross-distro. Thus, it is highly recommended you use it.

1. Download GNOME Builder.
2. In Builder, click the "Clone Repository" button at the bottom, using https://github.com/SeaDve/Kooha.git as the URL.
3. Click the build button at the top once the project is loaded.

The following packages are required to build Kooha:

• meson
• ninja
• appstream-glib
• python3
• python3-gobject
• gstreamer
• gtk4
• libadwaita

git clone https://github.com/SeaDve/Kooha.git
cd Kooha
meson _build --prefix=/usr/local
ninja -C _build install

Kooha is free and will always be for everyone to use. If you like the project and would like to support and fund it, you may donate through Liberapay.

RecApp greatly inspired the creation of Kooha. And also, a warm thank you to all the contributors and translators from Weblate.
