How to Build?

• Install Rust, Cargo, and qt6
• Run make debug to debug the desktop platform application
• Run make build-release to build a release version desktop application for Wayland wlr. E.g.: Sway and Hyprland.
• Run make build-release features=wayland-portal to build a release version desktop application for Wayland XDG Desktop Portal. E.g.: Ubuntu and KDE.
• Run make build-release features=windows to build a release version desktop application for Windows.
• Run make cursor-release to build the program for fetching the cursor position. This program needs to be used together with the portal version of wayshot.
• Refer to Makefile for more information

Slint Version Upgrade

Dynamic z support patches are applied to the components in the vendor directory. The patches live in ./patches/slint-dynamic-z/patches, so do not upgrade the Slint version casually. The Slint version is also pinned in Cargo. If you need a newer Slint version, you can use AI to regenerate suitable patches. Then run ./patches/slint-dynamic-z/patches/vendor.sh wayshot to apply the updated patches to the Slint dependencies in the vendor directory.

Alternatively, if you upgrade to the latest Slint and do not need dynamic z support, comment out the patched libraries in the [patch.crates-io] section of Cargo.toml:

i-slint-core = { path = "vendor/i-slint-core" }
i-slint-compiler = { path = "vendor/i-slint-compiler" }
i-slint-backend-qt = { path = "vendor/i-slint-backend-qt" }

Troubleshooting

• Using the Qt backend can resolve the issue of fuzzy fonts on the Windows platform. It is also recommended to prioritize the Qt backend to maintain a consistent build environment with the developers.

• Check program output log information: RUST_LOG=debug wayshot. Available log levels: debug, info, warn, error

• To use the cursor tracking feature with the Wayland xdg portal version, it needs to be used together with the wayshot-cursor program. The program can be downloaded from the Github page. The program must be run with administrator privileges: sudo -E wayshot-cursor. If you need to view logs, you can use: RUST_LOG=debug sudo -E wayshot-cursor. Available log levels: debug, info, warn, error

• Program version selection:

  • portal version: Ubuntu and KDE, etc.
  • wlr version: Sway and Hyprland, etc.

• Install build dependencies on Ubuntu:

  sudo apt install \
    libxcb-composite0-dev imagemagick libasound2-dev libpipewire-0.3-dev libx11-dev pkg-config \
    libxi-dev libxtst-dev libevdev-dev libfontconfig-dev libavcodec-dev libavformat-dev libavutil-dev \
    libswscale-dev libavfilter-dev libavdevice-dev libssl-dev clang libclang-dev libx264-dev libx265-dev \
    libfdk-aac-dev libmp3lame-dev libopus-dev libvpx-dev libvorbis-dev qt6-base-dev qt6-tools-dev qt6-tools-dev-tools
  

• Windows build dependencies:

  • Windows compiles ffmpeg-next

    • Install LLVM (through official installer, Visual Studio, Chocolatey, or any other means), and add LLVM's bin path to PATH, or set LIBCLANG_PATH to that (see clang-sys documentation for additional info).
    • Download ffmpeg and x264.dll
    • Install FFmpeg (complete with headers) through any means, e.g. downloading a pre-built "full_build-shared" version from https://ffmpeg.org/download.html. Set FFMPEG_DIR to the directory containing include and lib.
    • Add FFmpeg's bin path to the PATH environment variable.
    • git bash example:

    export FFMPEG_DIR=C:/ffmpeg-8.0.1-full_build-shared
    export LIBCLANG_PATH="C:/Program Files/Microsoft Visual Studio/2022/Community/VC/Tools/Llvm/x64/bin"
    export PATH=$PATH:"C:/ffmpeg-8.0.1-full_build-shared/bin":"/path/to/x264.dll"
    make build-release features=windows
    

  • Set up Qt dependencies

    • How to find Qt
    • Install Qt6, and add the directory containing qmake to PATH: export PATH=$PATH:"C:/Qt/6.11.1/msvc2022_64/bin"

How to Configure STUN and TURN Servers

• Download and install coturn

• Generate certificate and key: openssl req -x509 -newkey rsa:1024 -keyout /tmp/turn_key.pem -out /tmp/turn_cert.pem -days 9999 -nodes

• Edit the configuration.

  • Default location: /etc/turnserver.conf or /etc/coturn/turnserver.conf

  • Example configuration:

  listening-ip=0.0.0.0
  listening-port=3478
  relay-ip=192.168.10.8
  external-ip=192.168.10.8
  
  tls-listening-port=5349
  cert=/tmp/turn_cert.pem
  pkey=/tmp/turn_key.pem
  
  realm=example.com
  
  lt-cred-mech
  user=foo:123456
  
  # no-auth
  no-cli
  verbose
  

• Testing

  • turnserver -c /etc/turnserver.conf
  • Test using Trickle ICE
  • TURN server address format: turn:192.168.10.1:3478
