Live channels are often carried as transport stream over UDP or RTP multicast. Often such a stream must be handed over to a 3rd party for further processing or distribution, via a dedicated L2 Ethernet link. In practice, to ensure network isolation, this requires copying the multicast stream between two VLANs (with optional processing), an operation performed by expensive and proprietary hardware equipments such as DCMs. This presentation will explore the options using standard PCs and OSS such as DVBlast. For even better isolation, the speaker will also explore software virtualization using Linux/KVM and the SR-IOV feature of some network cards. The use of these technologies with multicast has proven difficult, as this case study will show.

Upipe developers annual meeting.

The Open Media devroom addresses the topics as found in broadcast (radio/TV) and Web media technologies such as video/audio encoding, playout, streaming, broadcasting, metadata. Information of related activities to this topic. This session is a discussion with attendees on ideas for future events.

Upipe is a flexible dataflow framework with multiple structural innovations which have been discussed in previous FOSDEM talks. In this talk, the speaker will give an overview of the available modules, with real-life use cases from television broadcast professionals.

Presentation of the talks of the schedule of this year.

Upipe is primarily designed to be the core of a multimedia player, transcoder or streamer. The framework organizes the processing of incoming data buffer inside a pipeline of modules. It exposes core types for buffers and modules (called “pipes”), and the API of communication between pipes and between the application and pipes.

The meetup is for everyone interested in our project and community, to discuss the future orientations and problems.

Upipe is a recent project, designed to build custom multimedia players, transcoders or streamers. The presenter will explain how the use of Upipe in OpenHeadend products enabled them with advanced video processing capabilities, and will highlight the features that make Upipe so adapted to these use cases.

Upipe is a flexible dataflow framework. The framework organizes the processing of incoming data in buffers inside a pipeline of modules. It exposes core types for buffers and modules (called "pipes"), and the API for communication between pipes and between the application and pipes. This presentation will include examples of complex pipelines performing video processing, and detail the unique features of Upipe that make the lives of developers easier.

The presenter will explain Automatic Multicast Tunneling, a draft RFC allowing to extend multicast content distribution to unicast-only connected receivers, and its implementation in the flexible multimedia framework Upipe. He will also show how it is possible to take advantage of AMT in web browser, using the Native Client plug-in of Upipe.

Upipe is a brand new flexible dataflow framework. It is primarily designed to be the core of a multimedia player, transcoder or streamer. The framework organizes the processing of incoming data in buffers inside a pipeline of modules. It exposes core types for buffers and modules (called "pipes"), and the API for communication between pipes and between the application and pipes. This presentation will show how developers can take advantage of Upipe to build complex processing pipelines.
