  • Hardware accelerated video decoding on Windows, Mac, and Linux
  • H.264, HEVC, and AV1 codec support (AV1 requires Sunshine and a supported host GPU)
  • HDR streaming support
  • 7.1 surround sound audio support
  • 10-point multitouch support (Sunshine only)
  • Gamepad support with force feedback and motion controls for up to 16 players
  • Support for both pointer capture (for games) and direct mouse control (for remote desktop)

Windows Build Requirements

  • Qt 5.15 SDK or later. Qt 6 is also supported for x64 and ARM64 builds.
  • Visual Studio 2022 (Community edition is fine)
  • Select MSVC option during Qt installation. MinGW is not supported.
  • 7-Zip (only if building installers for non-development PCs)

macOS Build Requirements

  • Qt 6.4 SDK or later
  • Xcode 13 or later
  • create-dmg (only if building DMGs for use on non-development Macs)

Linux/Unix Build Requirements

  • Qt 5.9 SDK or later. Qt 6 is also supported.
  • GCC or Clang
  • Install the required packages:
    • Debian/Ubuntu: libegl1-mesa-dev libgl1-mesa-dev libopus-dev libqt5svg5-dev libsdl2-dev libsdl2-ttf-dev libssl-dev libavcodec-dev libavformat-dev libva-dev libvdpau-dev libxkbcommon-dev qtwayland5 qt5-qmake qtbase5-dev qtdeclarative5-dev qtquickcontrols2-5-dev wayland-protocols qml-module-qtquick-controls2 qml-module-qtquick-layouts qml-module-qtquick-window2 qml-module-qtquick2
    • RedHat/Fedora: openssl-devel SDL2-devel SDL2_ttf-devel ffmpeg-devel qt5-qtsvg-devel qt5-qtquickcontrols2-devel libva-devel libvdpau-devel opus-devel pulseaudio-libs-devel alsa-lib-devel
  • FFmpeg 4.0 or later is required to build. If your distro doesn't package FFmpeg 4.0 or later, you can build and install it from source on
  • Building the Vulkan HDR renderer requires a libplacebo-dev/libplacebo-devel version of at least v338.0 and FFmpeg 6.1 or later.

Steam Link Build Requirements

  • Steam Link SDK cloned on your build system
  • STEAMLINK_SDK_PATH environment variable set to the Steam Link SDK path

Build Setup Steps

  1. Install the latest Qt SDK (and optionally, the Qt Creator IDE) from
    • You can install Qt via Homebrew on macOS, but you will need to use brew install qt --with-debug to be able to create debug builds of Moonlight.
    • You may also use your Linux distro's package manager for the Qt SDK as long as the packages are Qt 5.9 or later.
    • This step is not required for building on Steam Link, because the Steam Link SDK includes Qt 5.14.
  2. Run git submodule update --init --recursive from within moonlight-qt/
  3. Open the project in Qt Creator or build from qmake on the command line.
    • To build a binary for use on non-development machines, use the scripts in the scripts folder.
      • For Windows builds, use scripts\build-arch.bat and scripts\generate-bundle.bat. Execute these scripts from the root of the repository within a Qt command prompt. Ensure 7-Zip binary directory is on your %PATH%.
      • For macOS builds, use scripts/ Execute this script from the root of the repository and ensure Qt's bin folder is in your $PATH.
      • For Steam Link builds, run scripts/ from the root of the repository.
    • To build from the command line for development use on macOS or Linux, run qmake then make debug or make release
    • To create an embedded build for a single-purpose device, use qmake "CONFIG+=embedded" and build normally.
      • This build will lack windowed mode, Discord/Help links, and other features that don't make sense on an embedded device.
      • For platforms with poor GPU performance, add "CONFIG+=gpuslow" to prefer direct KMSDRM rendering over GL/Vulkan renderers. Direct KMSDRM rendering can use dedicated YUV/RGB conversion and scaling hardware rather than slower GPU shaders for these operations.
