Video over DDS Application (VoDA)
The Video over DDS Application (VoDA) is a software which allows real-time video data from a webcam to be transmitted using GStreamer and the Data Distribution Services (DDS) middleware. Using DDS as a communication mechanism, allows the video data to be transmitted in a data-centric manner with all the functionalities and advantages of the DDS Quality of Service (QoS) specifications. A demonstration video and detailed technical description is available on our website at http://www.s2e-systems.com/our-projects/videooverdds/
The project is developed using Qt Creator and this is the recommended IDE to build the software. To be able to build and run the software the following packages must be available on your system:
- GStreamer development and runtime https://gstreamer.freedesktop.org (v 1.16.0)
- ADLINK OpenSplice Community edition https://github.com/ADLINK-IST/opensplice/releases (v 6.9.19)
- Qt https://www.qt.io/ (v 5.12)
While other version of these components might work, these are the ones used for development.
To build the software the CMakeLists.txt files use the following environment variables to search for the dependent libraries:
- OSPL_HOME pointing to the folder where OpenSplice is installed
- GSTREAMER_1_0_ROOT_X86_64 to the folder where GStreamer is installed
For run the software the shared library binaries must be added to the PATH environment variable in Windows and to the ldconfig search directories in Linux. E.g.:
If you have problems building start by checking that these variables exist and are correctly configured. The software should also build on Linux and cross-compile for other platforms (e.g Linux on ARM computers), though the build steps are dependent on your own configuration.
