Description:	Many use cases today require synchronised multimedia handling between several, independent devices, possibly in different rooms. These requirements arise in consumer use cases, like multi-room playback of videos on TVs, mobile devices and other parts of a home entertainment system, to allow the user to switch between rooms without interrupting his multimedia experience. Similar requirements also arise in industrial and professional use cases, for example for building video walls as used for digital signage or control rooms, or for distributed live media processing and mixing in professional media production and editing scenarios. In this talk we will discuss how the flexibility of the GStreamer multimedia framework allows to implement these use cases, and which features are already provided to make it very simple to develop such applications. We will briefly introduce what GStreamer is and how data flow handling and synchronisation works. After this we will discuss how various open standards like RTP/RTSP and PTP or NTP can be leveraged to implement these use cases, while providing interoperability with other solutions. We will discuss how these are integrated into GStreamer and which challenges exist. GStreamer is a Free Software multimedia framework, based on the concept of media processing pipelines. Pipelines in GStreamer are built from small, composable components, like codecs, filters, sources (inputs) and sinks (outputs). These components are combined to bigger, more complex building blocks doing more high-level tasks. GStreamer is nowadays used in many areas, from phones and desktop applications to TVs and airplanes. markdown
