Description

This talk will cover the use of the explicit DMA Fence in multimedia pipelines and how these fences can be used to improve smoothness and reduce latency in your streaming application. We will also outline how we plan to integrate these new kernel object in GStreamer framework.

Nicolas Dufresne is a Principal Multimedia Engineer at Collabora. Based in Montréal, he was initially a generalist developer with background in STB development. Nicolas started in 2011 contributing to GStreamer Multimedia Framework adding infrastructure and primitives to support accelerated upload of buffers to GL textures. Today, Nicolas is implicated in both GStreamer and Linux Media communities to help create a solid support for CODEC on Linux.
