Since GStreamer is O pen Source\, anyone can build that expertise\, provided they can break pro blems down and trace them to their origin.\n\nIn this talk\, Nicolas will describe the methods he uses in practice such as: splitting bitstreams int o smaller parts\, applying advanced tracing to uncover what is really happ ening\, and defining clear expectations of correct behaviour to guide debu gging. The goal is not only to fix the immediate bug\, but to improve the code so that the same area does not need to be revisited later. This talk is intended for application and plugin developers\, and the approaches dis cussed will be useful both to newcomers and to very experienced developers .\n\nhttps://indico.freedesktop.org/event/11/contributions/505/ LOCATION:Barbican Centre URL:https://indico.freedesktop.org/event/11/contributions/505/ END:VEVENT BEGIN:VEVENT SUMMARY:Rebuilding Our Video Server Engine on GStreamer DTSTART;VALUE=DATE-TIME:20251024T132000Z DTEND;VALUE=DATE-TIME:20251024T135000Z DTSTAMP;VALUE=DATE-TIME:20260913T085842Z UID:indico-contribution-58-473@indico.freedesktop.org DESCRIPTION:Speakers: Ray Tiley (Tightrope Media Systems)\nStarting in the spring of 2018\, our company has rebuilt the core technology of our video server platform on top of GStreamer. What started as a proof-of-concept t o solve a cost of goods problem grew into a complete re-architecture of ou r application\, enabling new products and solutions we never thought possi ble before.\n\nIn this talk\, I’ll share our journey with GStreamer: how we first discovered it\, what made it stand out from other frameworks\, a nd how it gradually became the foundation of our business.

Time remapping enables powerful video effects like slow motion\, fast for ward\, and reverse playback by manipulating the relationship between input and output timestamps. We'll explore how this feature has been implemente d at the GStreamer and NLE level. The presentation will cover the core GSt reamer elements involved\, the challenges we faced\, and how these capabil ities are exposed through GES for video editing applications. We'll also d iscuss the roadmap ahead\, including exploring future work on dynamic spee d changes during playback (smoothly transitioning from normal to slow moti on while playing) and other improvements to the GES stack.\n\nhttps://indi co.freedesktop.org/event/11/contributions/472/ LOCATION:Barbican Centre URL:https://indico.freedesktop.org/event/11/contributions/472/ END:VEVENT BEGIN:VEVENT SUMMARY:Auxiliary Stream Wrangling in playbin3 DTSTART;VALUE=DATE-TIME:20251024T111500Z DTEND;VALUE=DATE-TIME:20251024T114500Z DTSTAMP;VALUE=DATE-TIME:20260913T085842Z UID:indico-contribution-58-510@indico.freedesktop.org DESCRIPTION:Speakers: Jan Schmidt (Centricular Ltd)\nGStreamer’s playbin 3 element provides a convenient and simple interface for basic media playb ack. Like earlier playbin elements\, it has some support for external subt itles\, but with some limitations. Extending it to handle multiple auxilia ry streams - such as multiple audio or subtitle tracks - reveals a surpris ing number of complexities.\n\nThis talk delves into the challenges faced when adding robust auxiliary stream support to playbin3\, covering bugs fo und\, pipeline negotiation intricacies\, state management issues\, and the corner cases that arose.\n\nhttps://indico.freedesktop.org/event/11/contr ibutions/510/ LOCATION:Barbican Centre URL:https://indico.freedesktop.org/event/11/contributions/510/ END:VEVENT BEGIN:VEVENT SUMMARY:GStreamer at Scale: Recent Lessons from Real-World Video Conferenc ing DTSTART;VALUE=DATE-TIME:20251024T084500Z DTEND;VALUE=DATE-TIME:20251024T092500Z DTSTAMP;VALUE=DATE-TIME:20260913T085842Z UID:indico-contribution-58-512@indico.freedesktop.org DESCRIPTION:Speakers: Håvard Graff (Pexip)\nAt Pexip\, GStreamer powers o ur global video conferencing platform\, processing real-time media for mil lions of users. Since the last GStreamer Conference\, we’ve continued to evolve our use of the framework\, focusing on interoperability\, scaling\ , and performance in production.\n\nIn this talk\, we’ll share highlight s from the past couple of years: TWCC statistics\, device monitoring and s inks\, GstBin teardown optimizations\, RTP session SSRC handling\, pipelin e auto-removal\, and more\; covering both the challenges faced and the imp rovements contributed back to the community.\n\nhttps://indico.freedesktop .org/event/11/contributions/512/ LOCATION:Barbican Centre URL:https://indico.freedesktop.org/event/11/contributions/512/ END:VEVENT BEGIN:VEVENT SUMMARY:A new era for GStreamer C++ bindings DTSTART;VALUE=DATE-TIME:20251023T110000Z DTEND;VALUE=DATE-TIME:20251023T113000Z DTSTAMP;VALUE=DATE-TIME:20260913T085842Z UID:indico-contribution-58-477@indico.freedesktop.org DESCRIPTION:Speakers: Sebastian Dröge (Centricular Ltd)\nA common questio n from people who are interested in using GStreamer and who are planning t o use C++ is\, which C++ bindings to use. Most of the available choices so far are essentially unmaintained or not widely used\, so the recommendati on was usually to use the C API directly. I hope to change this recommenda tion now.\n\nThis year a new C++ bindings generator for GObject-based libr aries was announced and gained some traction in GNOME: peel. Unlike altern atives\, it is providing headers-only\, dependency-less and zero-cost bind ings while making use of modern C++ features.\n\nIn this talk I will give an overview of peel: how to use it\, the kind of bindings API it provides and why I believe you should really consider it for any future C++ project making use of GStreamer\, no matter if application\, library or GStreamer plugin.\n\nhttps://indico.freedesktop.org/event/11/contributions/477/ LOCATION:Barbican Centre URL:https://indico.freedesktop.org/event/11/contributions/477/ END:VEVENT BEGIN:VEVENT SUMMARY:Rusty Pipes and Oxidized Wires DTSTART;VALUE=DATE-TIME:20251024T153000Z DTEND;VALUE=DATE-TIME:20251024T155000Z DTSTAMP;VALUE=DATE-TIME:20260913T085842Z UID:indico-contribution-58-515@indico.freedesktop.org DESCRIPTION:Speakers: Arun Raghavan (Valve Corporation)\nEarlier this year \, I began writing a native PipeWire client library in Rust. The aim is to provide a safer alternative to the bindings around the C library\, while also reducing the amount of boilerplate in both the library implementation and the user-facing API.\n\nAchieving parity with the C API is no small t ask. In this talk\, I will go over the overall approach to solving the pro blem\, review the current state of the library (basic clients are already possible!)\, and chart a course to a complete native Rust API for PipeWire .\n\nI will also take a detour into the challenges of using Rust for a low -level system library\, such as reconciling the PipeWire API's object life cycle with Rust's ownership and lifetime system.\n\nhttps://indico.freedes ktop.org/event/11/contributions/515/ LOCATION:Barbican Centre URL:https://indico.freedesktop.org/event/11/contributions/515/ END:VEVENT END:VCALENDAR
