17. Audio source separation using snakes, crabs and torches

Sebastian Dröge (Centricular Ltd)

Audio source separation is the process of separating the individual sources from a mixed audio stream. This can be used, for example, to remove the vocals from a song in a karaoke application, to extract voice from a movie to allow for better transcription without background noise, or to remove one specific instrument from your favorite song and playing that instrument yourself.

20. burn: a little case study on using GstAnalytics from Rust

Sebastian Dröge (Centricular Ltd)

Almost all existing code using the GstAnalytics API is in C or Python: inference elements, tensor decoders and all kinds of infrastructure elements.

In this lightning talk I will talk about my experience writing an inference element around the Rust burn deep-learning / machine-learning framework, writing a tensor decoder for YOLOX in Rust, and how it integrates with the remaining...

29. Fallback Streaming for RTSP Server

Axel Tobieson (Spiideo)

We wanted to serve content immediately while waiting for the primary source to arrive.
To solve this, we implemented a fallback mechanism using the fallbackswitch element combined with a custom parsebinloop element that continuously loops a seekable file source with seamless timestamps, making it appear as a live stream.

The system maintains two sources: the incoming primary stream...

38. Fast and dirty: vibe coding use case plugging the NVIDIA kernel into GStreamer streams

jesus luque

The talk introduces the idea of vibe coding and how it fits within GStreamer’s plugin architecture. It shows how a minimal GPU-accelerated plugin can load and run CUDA (.cu) code on the fly, making GPU integration faster and more intuitive. It also covers how quick QA checks can be added during development to test stability and performance. This approach opens a new world for technical...

24. GstVA and GStreamer-VAAPI updates

Victor Manuel Jáquez Leal (Igalia)

We have removed GStreamer-VAAPI subproject. It's mostly replaced by GstVA in gst-plugins-bad. We will talk about what's missing and how does the roadmap look.

44. pexLGPL bundle

Mr Tulio Beloqui (Pexip)

A story of how we pushed the limits of LGPL compliance and created a monster dynamic library to rule them all.

51. Reading v4l2 data from MR813 devices in a way that doesn't suck

Vivia Nikolaidou

When your device's v4l2 implementation is so particular that it turns out to be easier to write a new element than to patch v4l2src

3. Showing the invisible: Analysing buffer flow with tracers

François Laignel (Centricular ltd)

This talk will show how the buffer lateness, queue levels & pad push timings tracers can assist GStreamer developers in analysing buffer flows.

23. soothe: a proposal for encoder testing

Victor Manuel Jáquez Leal (Igalia)

https://github.com/Igalia/soothe

Soothe is a testing framework written in Python for encoder quality. It's a command line interface application that runs a number of test suites with the supported encoders. Its purpose is to compare different encoder implementations and configurations. It uses VMAF binary to measure the transcoded videos.

9. Video Frame Scheduler Plugin for Improving WebRTC Playback Quality

HAEJUNG HWANG (LG Electronics)

In WebRTC-based applications, video frames are often delivered at irregular intervals due to the nature of real-time communication. This irregularity can cause issues in waylandsink, which commits frames based on the arrival of frame_redraw_cb signals.

As a result, even when all frames are correctly delivered—for example, in a 60fps video where all 60 frames reach waylandsink—frames may...

26. Vulkan Video: pipeline update

Stéphane Cerveau (Igalia)

State of the art of the present and coming Vulkan video elements. We'll talk about architecture, codecs and challenges to achieve vulkan support ...

40. What's up with Video4Linux support

Nicolas Dufresne (Collabora)

Nicolas will share the latest updates on Video4Linux support in GStreamer, highlighting recent changes, ongoing integration work, and developments from the broader Linux Media community. This lightning talk continues the annual tradition of keeping the GStreamer community up to date with the fast-moving V4L2 ecosystem.
