40. A GStreamer-Based Performance Evaluation Tool for End-to-End Visual AI Pipelines

Dr Jan Gorecki (Intel)

Evaluating the performance of GStreamer-based visual AI pipelines on heterogeneous hardware is a complex systems engineering challenge. Simple metrics like raw TOPS are insufficient for understanding real-world performance, which is heavily impacted by codec complexity, model architecture, and concurrent system resource contention across the CPU, GPU, and NPU.
This presentation will...

24. A new Media Source Extensions implementation in GStreamer for cross-platform apps

Sebastian Dröge (Centricular Ltd)

Lightning talks

GStreamer has had a Media Source Extensions (MSE) implementation for 3 years now but has seen basically no adoption. For a project we recently needed an API that allowed more control than just "play this file", and ideally would be able to share one implementation of a custom streaming protocol across platforms: iOS and tvOS, Android, and the web. MSE appeared as an ideal candidate for...

28. A new MPEG-TS demuxer in Rust

Edward Hervey (Centricular Ltd)

A follow up to last year's mpeg-ts talk, explaining the investigation and implementation of writing a mpeg-ts crate and demuxer in rust

32. Building a Ringbuffer - Going in circles with V4L2 and PipeWire

Simon Himmelbauer

We implemented a ringbuffer element to keep hundreds of video frames in a GStreamer pipeline and only emit buffers to the sink when requested. While its implementation was straightforward, we found out that other components, such as Video4Linux2 and PipeWire, are not primarily designed for keeping large amount of frames in memory for extended periods.
Specifically, we extended PipeWire to...

17. Color, tracing and WebAssembly: a year of GStreamer for video editing

Thibault Saunier (Igalia)

This talk will give an update on the work done over the last year in GStreamer and GStreamer Editing Services (GES), most of it now upstream or on its way there.

We'll start with the work done to give GStreamer a proper color correction story: the new float video formats, what is needed to composite and grade in scene linear, and the OpenColorIO integration we are working on.

This talk...

30. Digitally Signed Content & C2PA

Diego Nieto Munoz (Fluendo)

This talk presents the implementation of Digitally Signed Content (DSC) within GStreamer to ensure trustworthy video authenticity. We'll demonstrate our new dscsigner element, which generates cryptographic signatures for coded bitstreams, alongside dscverifier, which verifies video authenticity in real-time. The presentation covers the integration of JVET supplemental enhancement information...

31. Dolby/AC-4: The plan to support the Dolby ecosystem in GStreamer

Finally, the session will conclude with an outlook on the future,...

5. Embedded Reality: GStreamer Versioning strategy on SoC Products

Kye Yeon Ko

Lightning talks

While GStreamer is evolving rapidly, SoC-based embedded products rely on versions supported by the SoC manufacturer.

For this reason, it is impossible to immediately adopt the latest version; this is a reality faced by all teams developing embedded products, such as TVs, set-top boxes, and mobile devices.

In this reality where using older versions is unavoidable, we introduce three...

22. Every Camera Is a Snowflake: Building a VMS That Works With Thousands of Device Models

James Nickerson

IP cameras nominally share common protocols, but in practice every manufacturer and model deviates in its own way. Drawing on our experience building the Orchid VMS, this talk covers what a video management system must tolerate to work with the broadest possible range of devices, and the per-manufacturer and per-model workarounds we manage through a quirks system when tolerance alone isn't...

41. Exploring GStreamer as a media backend for game engines

Dominique Leroux

Game engines serve a broad community of creators, but multimedia needs can outgrow the capabilities and extensibility of their built-in players. As part of an independent exploration of how GStreamer could help, and following earlier community efforts in this area, I have been developing experimental plugins for Unity, Godot, and Unreal Engine to explore both the opportunities and the...

36. Fluster over the course of 2026

Rubén Gonzalez

• New decoders & test suites
• The new sample comparison method that allows tolerance with the audio reference decoder.

Common design patterns in WebKit will be introduced, as a basis to understand the design of the modules to be presented next: Regular and Media Source Extensions video playback, Encrypted Media Extensions using the Thunder/OpenCDM...

2. Ingesting thousands of streams over SRT on the same endpoint

Jonas Danielsson (Spiideo)

At Spiideo, we work with sports clubs and leagues to help them analyze and broadcast games. We install cameras at their venues and process the video to add object detection and autofollow capabilities, ingesting 4K H.264/H.265 video over SRT.

We do not control the network infrastructure at these sites, and we're not going to ask sports clubs to open all "ephemeral outgoing UDP ports" on...

46. Latency is bad, isn't it?

Jan Schmidt (Centricular Ltd)

The goal of real-time media processing is to minimise latency. It's the enemy, and hides in many places.

Where? Well, let's investigate, and see what tools we have to fight it with. We'll kill it with fire, or just maybe... learn to be friends?

42. Let's (re) negotiate!

Mathieu Duponchelle (Centricular)

GStreamer's negotiation system is a powerful and unique mechanism, with some shortcomings that have been identified over the years.

In this talk I will present various experiments I have been implementing for testing new, non-backwards compatible design ideas, with the goal of retaining the capabilities of the existing system and addressing its shortcomings.

18. Let's solve our long standing issues: time for GStreamer 2.0 ?

Thibault Saunier (Igalia)

GStreamer 1.0 is 14 years old now. It has served us well, but it carries a lot of historical baggage, and even though we have always managed to move forward, that has a cost: the default threading model uses far more threads than necessary, and the threadshare plugin has shown we can do much better, caps negotiation is left to each element, with base classes helping only so much, and is hard...

19. librice: challenges with sans-io

Matthew Waters (Centricular)

ICE (Internet Connectivity Establishment) is a widely used standard for NAT (Network Address Translation) hole punching used extensively within the realm of WebRTC and in some cases SIP.

librice is a sans-IO library that handles the intricacies of ICE and has some new tricks up its sleeve. We will discuss the current state of librice, the work in progress and design decisions that have been...

25. Local transcription and translation with GStreamer: whisper.cpp + llama.cpp

Sebastian Dröge (Centricular Ltd)

Lightning talks

GStreamer already has all kinds of elements to use proprietary, cloud-based services for transcription and translation. Cloud services are not always an option for privacy and cost reasons.

In the last months, Mathieu and I have been working on adding a local option for this: a whisper.cpp-based speech-to-text element and a llama.cpp-based LLM text transformation and translation...

15. Making GStreamer Feel Native in Zig

Mr Per Andersen (TV 2)

Lightning talks

gstreamer-zig is an effort to create GStreamer bindings that feel native to Zig rather than a thin wrapper around the C API. The project aims to preserve GStreamer's concepts and flexibility while embracing Zig's modern language features and style. This lightning talk will briefly introduce the project, highlight some of the design choices and challenges involved, and show how GStreamer...

8. Multithreading in GStreamer: how do flushes work

Alicia Boya García (Igalia)

This talk gives an overview of the synchronization primitives used in GStreamer 1.0 pipelines: pad tasks, refcounting, push and pull call chains, serialized flow...

Then it uses these basic concepts to explain the special case of flushes: how they're supposed to work and why.

34. Outsourcing the boring work: setting up LLM agents for fixing bugs in legacy software

Kim Schmider (A&R TECH)

Lightning talks

Analyzing and fixing certain bugs in complex legacy software can be a time-draining endeavour: a fix of one or two lines of code can take many rounds of formulating and testing hypotheses. When such a round is costly due to a heavy build process and resource-constrained targets, this cost is exacerbated.

This talk is about how we have set up LLM agents to work autonomously taking over this...

44. Per pipeline logs tracer

Mathieu Duponchelle (Centricular)

Lightning talks

Many applications using GStreamer opt for spawning multiple pipelines, potentially inter-connected . Using large log levels to investigate an issue that happens in a single pipeline has unwelcome consequences (performance, disk usage when stored).

In this talk I will present a new tracer that sorts logs per pipeline, and can be configured with varying, per-pipeline log levels.

10. Permissions, Isolation and Streams: Redesigning WirePlumber's Core

Julian Bouzas (Collabora)

WirePlumber is the default session and policy manager for PipeWire, responsible for deciding which audio and video streams get connected to which devices or applications, and under what rules. In 2026 its internals got a significant update, and this talk will cover the biggest changes.

First, a new permission manager lets WirePlumber grant or restrict what each client is allowed to see and...

3. Real-time offshore crane teleoperations powered by GStreamer

Adam Blonsky

Abstract:

Offshore crane operations have traditionally required operators to work directly on platform cabins in hazardous environments—involving complex offshore logistics, high infrastructure costs, and extended periods away from home. Palfinger, in partnership with Aker BP, is transitioning these operations from physical cabins to onshore Integrated Operations Centers.

While remote...

13. Restream and GStreamer, a success story.

Loïc Le Page (Igalia)

29. Rock, paper, scissors

Xabier Rodríguez Calvar calvaris (Igalia)

Lightning talks

Let's play!

38. Secure Video Path Done the Right Way

Nicolas Dufresne (Collabora)

Many devices today ship with hardware-protected Digital Rights Management (DRM) pipelines built on GStreamer. Too often, developers assume that DRM is destined to remain proprietary and that the only way forward is with hacks and downstream workarounds. In practice, this leads to heavily diverging forks, making upgrades difficult, pinning products to ancient GStreamer versions, and exposing...

37. SIL 2 Video Streaming - Functional Safety from Lens to Glass

Rainhard Driessler (A&R TECH)

Abstract:
Live video streaming has become part of our daily lives. Apart from entertainment and surveillance, it is used across industries as part of perception systems for both human and non-human operators. Most commercial camera products are not designed for safety critical environments and may pose hazards that make them unfit for use in railway. We present our way to the world's first...

9. That F#$%ing AI Talk - Debugging GStreamer With AI Tools

Ray Tiley (Tightrope Media Systems)

In this talk we'll go over the struggles of maintaining a "complicated" GStreamer application and dealing with the hangs and crashes that come with large deployments. This year we built an automated pipeline that captures crash and hang dumps from our clients' machines, resolves them against the exact GStreamer build they were running, and uses commercially available AI models to point our...

35. The Quest for Python Analytics

Mr Aaron Boxer (Collabora Inc.)

At GStreamer Conference 2024 I proposed GStreamer as the ideal nervous system for feeding AI brains with data. As Python is the dominant language in AI, a new Python framework, gst-python-ml, was introduced to easily connect PyTorch models with GStreamer pipelines, with support for object detection, tracking, local speech to text and local text to speech.

This talk covers the many new...

11. Unifying GstAnalytics Metadata: Achieving Cross-Vendor Interoperability in Video Analytics

Mr Oskar Fiedot (Intel) , Pep Cots (Milestone Systems) , Daniel Morin (Collabora)

As the GStreamer framework continues to be a leading tool for building complex video analytic pipelines, the need for seamless interoperability across vendor components is more critical than ever. While the GstAnalytics library, introduced in GStreamer 1.24, provides a flexible foundation for representing AI-driven metadata, its very flexibility has resulted in slight differences between...

16. WebRTC in the Wild: It Works on My Network

Jake Foytik

IPConfigure has shipped GStreamer WebRTC in production video management products since 2018. This talk will outline the evolution of our WebRTC implementation, from hand-rolled pipelines that predate webrtcbin to our full migration onto it in 2022. It will also cover what actually breaks when you stream from on-premise recorders to browsers across networks you don't control: ICE and STUN...

20. WebRTC take 2, a decade later

Matthew Waters (Centricular)

The webrtcbin element was first proposed upstream a little less than a decode ago and presented 9 years ago at the GStreamer conference. In that past decade, every* web browser has grown support for WebRTC and thus has the functionality for real-time audio/video streaming.

We will look at some of the existing challenges the current webrtcbin design has faced and discuss some potential...

23. When the robots came for our parsers: GStreamer security in the age of LLMs

Sebastian Dröge (Centricular Ltd)

In the last months, there has been a lot of reporting on LLM-based tooling easily finding dozens of security vulnerabilities in open source software. Projects like the Linux kernel or curl are well known to have been hit by this heavily, with many discussions about the usefulness and validity of these reports and how this flood of reports can be handled. As GStreamer is used in many safety...

43. Whisper transcriber

Mathieu Duponchelle (Centricular)

Lightning talks

I will briefly present the new whisper transcriber, GStreamer's first transcriber that does not rely on a third party service.

39. Whither GStreamer 2.0 ? - Overview and Panel Discussion

Tim-Philipp Müller (Centricular)

A short high-level overview of what we know and don't know about the shape of GStreamer 2.0 and how we might get there.

Plus a panel discussion to bounce around ideas and identify priorities, and also collect input from the audience.

48. Why is MPEG-TS so hard?

Jan Schmidt (Centricular Ltd)

GStreamer has been able to produce MPEG-TS for decades, but the MPEG-TS it produces isn't always great. Why is that? What would it take to fix?

27. Write once, run anywhere inference with GStreamer

Sebastian Dröge (Centricular Ltd)

Modern devices come with multiple different hardware components that can be used for inference workflows: CPU, NPU, iGPU, dGPU, etc. The APIs to access them differ not only between the individual components and hardware vendors, but also between different platforms. To complicate the situation further, multiple hardware vendors provide extension libraries on top of GStreamer for accessing...
