With the wide variety of hardware and their various restrictions, implementing zero-copy in GStreamer can be difficult. In this talk, I would like revisit the mechanisms in place to help implement such pipeline and explain how this is being used in various context. I will also try to explain some of the well known and recently found traps that can lead to difficult to debug issues. This talk is addressed to plugin developers interested in enabling zero-copy while keeping GStreamer flexibility.
