GStreamer 1.0 introduced a new architecture that makes memory management easier. In particular, handling non-system memory and sharing it between elements is made easier.
While building a video sink for cairogles, Guillaume wanted to explore the possibility of sharing GPU memory (in his case, GL or GLES textures) between elements of a pipeline. In this talk, Guillaume will explain how he made the various parts fit together, and discuss the challenges that he has met and how he has worked on them.
