Capture your screen in an 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:

• 🎙️ Record microphone, desktop audio, or both at the same time
• 📼 Support for WebM, MP4, GIF, and Matroska formats
• 🖥️ Select a monitor or a portion of the screen to record
• 🛠️ Configurable saving location, pointer visibility, frame rate, and delay
• 🚀 Experimental hardware-accelerated encoding

😕 It Doesn't Work

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 screencast compatibility page of xdg-desktop-portal-wlr wiki may help determine 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.

⚙️ Experimental Features

These features are disabled by default due to stability issues and possible performance degradation. However, they can be enabled manually by running Kooha with KOOHA_EXPERIMENTAL env var set to all (e.g., KOOHA_EXPERIMENTAL=all flatpak run io.github.seadve.Kooha), or individually, by setting KOOHA_EXPERIMENTAL to the following keys (e.g., KOOHA_EXPERIMENTAL=experimental-formats,window-recording):

| Feature | Description | Issues | | ------------------------ | ----------------------------------------------------------------------- | ------------------------- | | all | Enables all experimental features | - | | experimental-formats | Enables other codecs (e.g., hardware-accelerate encoders, VP9, and AV1) | Stability | | multiple-video-sources | Enables recording multiple monitor or windows | Stability and performance | | window-recording | Enables recording a specific window | Flickering |

📋 Runtime Requirements

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

🏗️ Building from source

GNOME Builder

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.

Meson

Prerequisites

The following packages are required to build Kooha:

• meson
• ninja
• appstreamcli (for checks)
• cargo
• x264 (for MP4)
• gstreamer
• gstreamer-plugins-base
• gstreamer-plugins-ugly (for MP4)
• gstreamer-plugins-bad (for VA encoders)
• glib2
• gtk4
• libadwaita

Build Instruction

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

💝 Acknowledgment

I would like to express my gratitude to the contributors and translators of the project.

I would also like to thank the open-source software projects, libraries, and APIs that were used in developing this app, such as GStreamer, GTK, LibAdwaita, and many others, for making Kooha possible.

I would also like to acknowledge RecApp, which greatly inspired the creation of Kooha, as well as GNOME Screenshot, which served as a reference for Kooha's icon design.
