OpenRV uses submodules to pull some dependencies. When cloning the repository, make sure to do it recursively by using the following command:
git clone --recursive https://github.com/AcademySoftwareFoundation/OpenRV.gitIf you cloned the repo without setting the --recursive flag, you can initialize the submodule in another step with the
following command:
git submodule update --init --recursiveOpen RV is currently supported on the following operating systems:
Support for other operating systems is on a best effort basis.
You can use source rvcmds.sh to add common build aliases into your shell. After the first download following the
installation of the required dependencies, use rvbootstrap to set up, configure, and build Open RV with the default
options.
After the setup, you can use rvmk (the common build alias) to configure and build Open RV. You can also use rvmkd to
configure and build in Debug.
On macOS, if you want to build for a different deployment target than your current operating system, make sure to define the MACOSX_DEPLOYMENT_TARGET environment variable.
This repository uses a pre-commit to execute formatting before a commit. To install the pre-commit hooks:
pre-commit installTo clean your build directory and restart from a clean slate, use the rvclean common build alias, or delete
the _build folder.
Open RV automatically sets up a Python virtual environment when the user bootstraps (rvbootstrap), builds (rvbuild) or configures (rvcfg) their project. After each of these commands, you should see that the executing instance of the terminal is using a virtual environment with the name .venv.
If this is not the case or if you would like to set up your virtual environment directly, you can run the command rvenv.
Before first your first Open RV build, you must install some python dependencies.
Use the rvsetup common build alias to run the bootstrap step.
Please ensure that a virtual environment is running before this command is executed.
python3 -m pip install -r requirements.txtNote that on Windows, use the following command instead from an MSYS2-MinGW64 shell:
SETUPTOOLS_USE_DISTUTILS=stdlib python3 -m pip install --user --upgrade -r requirements.txtDownload the Blackmagicdesign® SDK to add Blackmagicdesign® output capability to Open RV (optional): https://www.blackmagicdesign.com/desktopvideo_sdk
Then set RV_DEPS_BMD_DECKLINK_SDK_ZIP_PATH to the path of the downloaded zip file on the rvcfg line.
Example:
rvcfg -DRV_DEPS_BMD_DECKLINK_SDK_ZIP_PATH='<downloads_path>/Blackmagic_DeckLink_SDK_14.1.zip'Download and install the NDI® SDK to add NDI® output capability to Open RV (optional): https://ndi.video/
This must be done before the configure step.
The project uses CMake and requires a configure step before building. It is during the configure step that you provide
your Qt package.
From the root of the repository, execute cmake and specify the path to an arbitrary build folder and the path to your
QT5 package.
Use the rvcfg (the common build alias) to run the configuration step. You can also use rvcfgd to configure in Debug.
Legal Notice: Non free FFmpeg codecs are disabled by default. Please check with your legal department whether you have the proper licenses and rights to use these codecs. ASWF is not responsible for any unlicensed use of these codecs.
The RV_FFMPEG_NON_FREE_DECODERS_TO_ENABLE and RV_FFMPEG_NON_FREE_ENCODERS_TO_ENABLE can optionally be specified at configure time to enable non free FFmpeg decoders and encoders respectively.
Example:
rvcfg -DRV_FFMPEG_NON_FREE_DECODERS_TO_ENABLE="aac;hevc" -DRV_FFMPEG_NON_FREE_ENCODERS_TO_ENABLE="aac"On Windows, you must specify the path to Strawberry perl for the OpenSSL build.
cmake -B _build -G "Visual Studio 16 2019" -A x64 -DCMAKE_BUILD_TYPE=Release -DRV_DEPS_WIN_PERL_ROOT=/c/Strawberry/perl/bin -DRV_DEPS_QT5_LOCATION=/c/path/to/your/Qt/Rootcmake -B _build -DCMAKE_BUILD_TYPE=Release -DRV_DEPS_QT5_LOCATION=/Path/To/Your/Qt5/RootTo keep your third-party builds between build cleanups, set -DRV_DEPS_BASE_DIR=/path/to/third/party.
Invoke the previously specified generator tool using cmake to run the build step (recommended).
Use the rvbuild (the common build alias) to run the build step. You can also use rvbuildd to build in Debug.
cmake --build _build --config Release -v --parallel=8 --target main_executableInvoke the tests using ctest.
Use the rvtest common build alias to start the tests.
ctest --test-dir _buildYou can run the test in parallel by specifying --parallel X, where X is the number of tests to run in parallel.
You can apply a filter with the -R flag to specify a regex.
You can run the tests with extra verbosity with the flag --extra-verbose.
Important: You cannot use
--extra-verbosewith--parallel. It's one or the other, not both.
Once the build ends, you can execute (or debug!) Open RV from the _build directory.
The path to the build is _build/stage/app. It contains everything required to have the proper debug symbols.
Invoke the install step using cmake. The install step prepares Open RV for packaging by building a copy of Open RV in
the _install folder.
The build system allows you to prepackage Open RV using cmake's install command. It will strip debug symbols if
required.
Then, it's up to you to either sign or package the result, or to do both. It should contain the minimum required to have a functional Open RV.
Use the rvinst common build alias to install OpenRV.
cmake --install _build --prefix _installSee THIRD-PARTY.md for license information about portions of Open RV that have been imported from other projects.
