Installation

Windows

Download and run the installer from the latest release.

MacOS

Download the app bundle for your processor architecture from the latest release and drag it to your Applications folder.

Instructions for running the first time

The MacOS binaries provided by this project are not signed with a "Developer ID Certificate". When you try to run the app for the first time you may get a warning from MacOS that it may be malicious software, the developer cannot be verified, it may be damaged, etc. Close the warning, go to System Settings -> Privacy & Security and click "Open Anyway". This should only be required the first time you open the app.

If you think this is annoying you can donate some money here so I can pay Apple for a developer account.

Linux

The project builds on Ubuntu in CI but I don't know enough about packaging for Linux to make release binaries. For now you need to build from source.

Building from source

  1. Install the Rust toolchain.
  2. Run cargo install --git https://github.com/avsaase/walksnail-osd-tool.git. The executable will be installed in $HOME/.cargo/bin/ and added to your path.
  3. To run the app you need the ffmpeg and ffprobe binaries in your path or placed next to the executable you just build.
  4. Run the app with walksnail-osd-tool.
