GStreamer is a highly versatile, cross-platform, plugin-based multimedia framework that caters to the whole range of multimedia needs. It can be used basically everywhere, from embedded devices like phones, TVs or drones to desktop applications or on huge server farms. In this talk we will discuss how Rust is the perfect match for GStreamer to evolve from its C roots and safely enter the future. Be it for application development on top of GStreamer or for the development of plugins, where the a

GObject subclassing in Rust for extending GTK+ & GStreamer

FOSDEM

Many commonly used libraries from other languages, especially GUI toolkits, make use of Object Oriented Programming (OOP). While Rust has support for many of the OOP concepts in one way or another, there is no easy way for implementing subclassing or inheritance. The topic of this talk will be how to implement subclassing and inheritance in safe Rust, based on the GObject C library. The GObject library is providing Java/ObjectiveC-style OOP features to C. It is used by the GTK+ UI toolkit, the GStreamer multimedia framework and various GNOME libraries. Apart from reasons why you would want to do this in Rust, this talk will cover the new implementation for subclassing that was recently integrated into the existing GLib/GObject, GTK+ and GStreamer bindings. These bindings allowed usage of existing GObject types before, but didn't provide any features to create new GObject types. In addition to usage of the subclassing implementation, a couple of details about the implementation will also be explained. Last but not least, an outlook in the future will be given for how one can take this even one step further with procedural macros to allow writing code that looks very close to Java or C#. This talk will not only be interesting for those who want to make use of GTK+ or GStreamer and extend those libraries, but will also cover various aspects about safely interfacing with C libraries from Rust and all kinds of type tricks to teach the Rust type-system about subclassing and making use of the type-system for enforcing various invariants at compile-time.

GStreamer & Rust

FOSDEM

GStreamer is a highly versatile, cross-platform, plugin-based multimedia framework that caters to the whole range of multimedia needs. It can be used basically everywhere, from embedded devices like phones, TVs or drones to desktop applications or on huge server farms. This talk will focus on how and why Rust looks like the perfect programming language for evolving GStreamer and provide a safer but still performant and even more productive development environment than C. Both GStreamer application development in Rust, and GStreamer plugin development will be covered. What is possible today already, for which applications can Rust be perfectly used already and which parts are still missing? How does it feel like to write an application in Rust compared to doing it in C? And how and why would one write GStreamer plugins in Rust to extend the framework and all applications with support for new codecs, filters or anything else? Afterwards there will be a short outlook into the future of Rust in the GStreamer project itself and for GStreamer application and plugin development.
