Membrane framework - bringing BEAM into world of multimedia and streaming

Media processing has never been a piece of cake - a large amount of data, tons of different formats, protocols and standards, growing latency and quality requirements. In this talk, Marcin will introduce you to the world of media streaming via Membrane Framework - his solution for dealing with multimedia without pain. The framework provides a set of so-called elements, which are composable blocks implementing different multimedia processing operations.


You’ll learn how to combine these blocks together to create reliable and scalable streaming pipelines.

Marcin will also show you how to develop your own element and integrate it with existing pipeline.


  • Anyone with interest in audio/video solutions or streaming
  • People interested in architecting frameworks or abstraction layers
  • Developers dealing with a lot of native code integrated with BEAM
