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

Sebastian Dröge (Centricular Ltd)

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...

5. Embedded Reality: GStreamer Versioning strategy on SoC Products

Kye Yeon Ko

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...

12. GStreamer highlights in Servo

Xabier Rodríguez Calvar calvaris (Igalia)

Servo is a web browser engine that uses GStreamer for playback. In this lightning talk we'll quickly go through the current status and plans for the near future.

47. GStreamer in and out of the box

Jan Schmidt (Centricular Ltd)

Did you know GStreamer now has an official Python wheel?

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

Sebastian Dröge (Centricular Ltd)

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)

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...

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

Kim Schmider (A&R TECH)

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)

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.

29. Rock, paper, scissors

Xabier Rodríguez Calvar calvaris (Igalia)

Let's play!

43. Whisper transcriber

Mathieu Duponchelle (Centricular)

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