Blue Recorder – simple screen recorder written in Rust

A screencast is a digital recording of computer screen output, typically carrying audio narration. Screencasting software takes a series of screenshots of a running application, recording the user’s actions, and creating a video file. The movies can be output in a variety of different formats.

Screencasts have a wide variety of uses. This type of software is also often used to demonstrate operating systems, software actions, website features, troubleshooting, and evaluating technical skills.

Blue Recorder is billed as a simple desktop recorder for Linux systems. It’s built using GTK4 and FFmpeg.


Blue Recorder is open source software. We did try to build the software without success.

We tested on Ubuntu 23.10. First, we installed the dependencies with the command:

$ sudo apt install build-essential clang cargo libappindicator3-1 x11-utils gettext pulseaudio ffmpeg

Clone the project’s GitHub repository.

$ git clone

Change into the newly created directory.

$ cd blue-recorder

Build the software.

$ cargo build --release

Failed to build

Oh dear, it didn’t build 🙁 Sometimes life is just too short to be faffing around working out why a build fails.

If it had built successfully on our Ubuntu test system there is a final step needed.

$ cp -a data interfaces po target/release

Rather than investigate why the build was unsuccessful, we took the easy way out. There’s a Flatpak (and a Snap) available. We used bauh to install the Flatpak.
