Video over the Data Distribution Service (DDS) using GStreamer

The Data Distribution Service is an emerging middleware that is used more and more in industry. An advantage is that for example multiple receivers can subscribe to one sender letting the middleware take care of the data distribution. The communication can be configured in so called Quality of Service settings to allow the adaption of the system to the network structure to where the application is deployed without recompiling. It is for example also possible to have multiple senders of video where one these is the preferred publisher and others are redundant and take over in case the preferred one fails. Multiple implementations of the DDS standard from various vendors exists thereunder also community editions that are open source.

We developed a demonstration application that showcases the usage of GStreamer with DDS in a cross-platform fashion. This allows the development and deployment of the application for Windows and embedded Linux from host-system. As such a redundant pair of camera devices can distribute the video of a wireless network to multiple receivers using different operating systems.

Stefan was working with the European Space Agency (ESA) where he used GStreamer to develop the transport of video from earth to space. Meanwhile he founded his own company S2E Software, Systems and Control together with a colleague also from ESA.
