Cerbero is a cross-platform build aggregator for Open Source projects that builds and creates native packages for different platforms, architectures and distributions. It supports both native compilation and cross compilation and can run on macOS, Linux, and Windows.
Projects are defined using recipe files (.recipe), which provide a description of the project being built such as name, version, licenses, sources and the way it's built. It also provide listing of files, which is later used for the packaging.
Packages are defined using package files (.package), describing the package name, version, license, maintainer and other fields used to create the packages. A package wraps a list of recipes, from which the list of files belonging to the package will be extracted.
Cerbero provides bootstrapping facilities for all platforms, but it still needs a minimum base to bootstrap on top of.
On Linux, you will only need a distribution with python >= 3.5. Cerbero will use your package manager to install all other required packages during bootstrap.
On macOS you will need to have install the following software:
- Python 3.5+ https://www.python.org/downloads/
Cerbero will build all other required packages during bootstrap.
The initial setup on Windows is somewhat longer since the required packages must be installed manually. Detailed steps on what you need to install are at the bottom of the page.
Despite the presence of
setup.py this tool does not need installation. It is invoked via the
cerbero-uninstalled script, which should be invoked as
./cerbero-uninstalled, or you can add
the cerbero directory in your path and invoke it as
Before using cerbero for the first time, you will need to run the bootstrap command. This command installs the missing parts of the build system using the packages manager when available, and also downloads the necessary toolchains when building for Windows or Android.
Note that this will take a while (a couple hours or even more on Windows).
$ ./cerbero-uninstalled bootstrap
# Help $ ./cerbero-uninstalled --help # Command-specific help $ ./cerbero-uninstalled <command> --help # List available recipes $ ./cerbero-uninstalled list # Build a recipe $ ./cerbero-uninstalled build glib # Force-rebuild a single recipe $ ./cerbero-uninstalled buildone glib # Create a package (this automatically builds all recipes in the package) $ ./cerbero-uninstalled package gstreamer-1.0
If you're using Cerbero to cross-compile to iOS, Android, or Cross-MinGW, you must select the appropriate config file and pass it to all steps: bootstrap, build, package, etc.
For example if you're on Linux and you want to build for Android Universal, you must run:
# Bootstrap for Android Universal on Linux $ ./cerbero-uninstalled -c config/cross-android-universal.cbc bootstrap # Build everything and package for Android Universal $ ./cerbero-uninstalled -c config/cross-android-universal.cbc package gstreamer-1.0
Here's a list of config files for each target machine:
|macOS System Framework||
On Windows, config files are used to select the architecture and variants are used to select the toolchain (MinGW, MSVC, UWP):
|UWP Universal||`cross-uwp-universal.cbc||(implicitly uwp)|
# Target MinGW 32-bit $ ./cerbero-uninstalled -c config/win32.cbc package gstreamer-1.0 # Target MSVC 64-bit $ ./cerbero-uninstalled -c config/win64.cbc -v visualstudio package gstreamer-1.0 # Target UWP, x86_64 $ ./cerbero-uninstalled -c config/win64.cbc -v uwp package gstreamer-1.0 # Target UWP, Cross ARM64 $ ./cerbero-uninstalled -c config/cross-win-arm64.cbc -v uwp package gstreamer-1.0 # Target UWP, All Supported Arches $ ./cerbero-uninstalled -c config/cross-uwp-universal.cbc package gstreamer-1.0
Enabling Optional Features with Variants
Cerbero controls optional and platform-specific features with
can see a full list of available variants by running:
$ ./cerbero-uninstalled --list-variants
Some variants are enabled by default while others are not. You can enable a particular variant by doing one of the following:
- Either invoke
-vargument, for example:
$ ./cerbero-uninstalled -v variantname [-c ...] package gstreamer-1.0
- Or, edit
variants = ['variantname']at the bottom. Create the file if it doesn't exist.
Multiple variants can either be separated by a comma or with multiple
arguments, for example the following are equivalent:
$ ./cerbero-uninstalled -v variantname1,variantname2 [-c ...] package gstreamer-1.0 $ ./cerbero-uninstalled -v variantname1 -v variantname2 [-c ...] package gstreamer-1.0
To explicitly disable a variant, use
In the case of multiple enabling/disable of the same variant, then the last condition on the command line will take effect. e.g. if novariantname is last then variantname is disabled.
Enabling Qt5 Support
Starting with version 1.15.2, Cerbero has built-in support for building the Qt5
QML GStreamer plugin. You can toggle that on by
You must also tell Cerbero where your Qt5 installation prefix is. You can do it
by setting the
QMAKE environment variable to point to the
qmake that you
want to use, f.ex.
When building for Android Universal with Qt < 5.14, instead of
must set the
QT5_PREFIX environment variable pointed to the directory
inside your prefix which contains all the android targets, f.ex.
$ export QMAKE='/path/to/Qt5.12.0/5.12.0/<target>/bin/qmake' $ ./cerbero-uninstalled -v qt5 [-c ...] package gstreamer-1.0
This will try to build the Qt5 QML plugin and error out if Qt5 could not be found or if the plugin could not be built. The plugin will be automatically added to the package outputted.
NOTE: The package outputted will not contain a copy of the Qt5 libraries in it. You must link to them while building your app yourself.
Enabling Hardware Codec Support
Starting with version 1.15.2, Cerbero has built-in support for building and packaging hardware codecs for Intel and Nvidia. If the appropriate variant is enabled, the plugin will either be built or Cerbero will error out if that's not possible.
Intel Hardware Codecs
For Intel, the variant to enable
intelmsdk which will build the
You must set the
INTELMEDIASDKROOT env var to point to your Intel Media
SDK prefix, or you must have the
SDK's pkgconfig prefix in
INTELMEDIASDKROOT automatically set by the installer. On Linux,
if you need to set this, you must set it to point to the directory that
contains the mediasdk
For VA-API, the variant to enable
vaapi which will build the gstreamer-vaapi plugins with all
options enabled if possible.
Nvidia Hardware Codecs
Since 1.17.1, the
nvcodec plugin does not need access to the Nvidia Video SDK
or the CUDA SDK. It now loads everything at runtime. Hence, it is now enabled
by default on all platforms.
Enabling Visual Studio Support
Starting with version 1.15.2, Cerbero supports building all GStreamer recipes,
all mandatory dependencies (such as glib, libffi, zlib, etc), and some external
dependencies with Visual Studio. You must explicitly opt-in to this by enabling
$ python ./cerbero-uninstalled -v visualstudio package gstreamer-1.0
If you already have a Cerbero build, it is highly recommended to run the
command before switching to building with Visual Studio.
Some plugins that require external dependencies will be automatically disabled when running in this mode.
Currently, most recipes that use Meson (
btype = BuildType.MESON) and those
that have the
can_msvc recipe property set to
True are built with Visual
Installing Minimum Requirements on Windows
IMPORTANT: Using cerbero on Windows with the GCC/MinGW toolchain requires a 64-bit operating system. The toolchain is only available for 64-bit and it can produce 32-bit or 64-bit binaries.
These steps are necessary for using Cerbero on Windows.
Install Python 3.5 or newer (either 32-bit or 64-bit)
Download the Windows executable installer and run it.
- On the first page of the installer, select the following:
On the second page, the defaults are fine
Third page, you must select the following options:
Enabled or Install .NET 3.5.1 Framework
On Windows 10, remove the Windows Store path entry from the PATH variable in the system settings. Otherwise, Cerbero will try to use the dummy Windows Store version of Python
Install Git for Windows
Download the Git for Windows installer and run it.
First page is the license
Next page is
Select Components, the defaults are fine, enable whatever else you prefer
Choosing the default editor used by Git, select whatever you prefer
Adjusting your PATH environment, you must select as shown in the screenshot
Choosing HTTPS transport backend, default is fine
Configuring the line ending conversions, you must select as shown in the screenshot
Configuring the terminal emulator, default is fine
Configuring extra options, defaults are fine
Git will be installed at
mingw-get-setup executable installer and run it.
First page, keep all the options as-is
Second page will download the latest package catalogue and base packages
Once done, the MinGW Installation Manager will open, select the following packages under Basic Setup:
Then, click on the
Installation menu and select
Apply Changes. MSYS will be
IMPORTANT: After installation, you must create a shortcut on the desktop to
C:\MinGW\msys\1.0\msys.bat which will run the MinGW shell. You must run
Cerbero from inside that.
NOTE: Cerbero does not use the MinGW compiler toolchain shipped with MSYS. We download our own custom GCC toolchain during bootstrap.
NOTE: MSYS is not the same as MSYS2, and the GStreamer project does not support running Cerbero inside the MSYS2 environment. Things may work or they may break, and you get to keep the pieces.
Install Visual Studio 2015 or newer
This is needed for correctly generating import libraries for recipes built with MinGW. Both the Community build and the Professional build are supported.
You must install the latest Windows 10 SDK when installing Visual Studio as shown below. You do not need any older Windows SDKs.
If you want to build for UWP (aka Universal Windows Platform), you have to use VS 2017 or newer, and you must also select the Universal Windows Platform workload:
You can find all versions of Visual Studio at: https://visualstudio.microsoft.com/vs/older-downloads/

Important Windows-specific Notes
You should add the cerbero git directory to the list of excluded folders in your anti-virus, or you will get random build failures when Autotools does file operations such as renames and deletions. It will also slow your build by about 3-4x.
Cerbero must be run in the MingGW shell, which is accessible from the main menu
or desktop. If it is not, create a shortcut on the desktop to
The path to your
$HOME must not contain spaces. If your Windows username
contains spaces, you can create a new directory in
/home and execute:
If you are using Windows 10, it is also highly recommended to enable "Developer Mode" in Windows Settings as shown below.
$ echo 'export HOME=/home/newdir' > ~/.profile
Then restart your shell and type
cd to go to the new home directory.
Note that inside the shell,
/ is mapped to
