UID:indico-contribution-11-478@indico.freedesktop.org
DESCRIPTION:Speakers: Sebastian Dröge (Centricular Ltd)\nAudio source sep
 aration is the process of separating the individual sources from a mixed a
 udio 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.\
 n\nIn this lightning talk I will present the GStreamer "demucs" plugin. Th
 e plugin uses a PyTorch music source separation model\, that is available 
 as an easily installable Python package\, from a GStreamer plugin written 
 in Rust. This mix of technologies provides some interesting technical puzz
 les.\n\nhttps://indico.freedesktop.org/event/11/contributions/478/

UID:indico-contribution-11-463@indico.freedesktop.org
DESCRIPTION:Speakers: George Kiagiadakis (Collabora)\nIn GStreamer\, the m
 edia pipeline operation is defined by threads that are continuously pushin
 g or pulling data through the pads of the linked elements. This is an eleg
 ant and very flexible way of operating the pipeline\, but there are certai
 n drawbacks.\n\nPipeWire follows a different approach\, using a single thr
 ead that wakes up elements in a dependency-based sequence to consume and p
 roduce data that is placed in shared memory. With that approach\, it can s
 chedule pipelines with a predictable processing latency that span across m
 ultiple processes\, quite efficiently. How does that work exactly and are 
 there drawbacks to that as well?\n\nThis talk aims to explain in depth and
  discuss pipeline operation and how to get the most out of different syste
 ms.\n\nhttps://indico.freedesktop.org/event/11/contributions/463/

DESCRIPTION:Speakers: Albert Sjölund (Axis Communications)\nThis talk wil
 l discuss the methods used to reduce latency in a bidirectional WebRTC pip
 eline\, i.e.\, video but primarily audio in both directions. The primary t
 opics are\n\n - Splitting the pipeline using intersrc/intersink\, discussi
 ng the global pipeline latency and how to do avoid unnecessary clock synci
 ng. This discusses pipeline latency and what is needed to allow media stre
 aming in two directions.\n - Investigating different audio sinks\, mainly 
 pipewire and alsa and its effect on overall latency\, both pipeline latenc
 y as well as perceived/measured latency.\n - Possible further improvements
 . Jitterbuffer\, external properties (pipewire properties like quantum)\, 
 mentioning webrtcbin2 from GStreamer that should potentially solve the fir
 st issue on its own. \n\nThe end result reduced latency from 650-700ms to 
 roughly 230ms\, with as low as 180ms depending on the setup\, making real-
 time communication possible\, with a goal of 150ms.\n\nhttps://indico.free

 e it provided a generic `addroi` filter for attaching ROI metadata that we
  could use for multiple encoders\, but GStreamer currently lacks a simple 
 way to define regions and pass them to encoders downstream\, and I wanted 
 to change this.  \n\nTo prototype this\, I built a small Rust plugin that 
 works similar to `addroi` to append `GstVideoRegionOfInterestMeta` to fram
 es and extended `x264enc` to consume it. In this lightning talk\, I will d
 emo the prototype and show some results of using it\, highlighting how a g

 g software that relies on GStreamer often comes down to experience and the
  ability to pinpoint where problems really come from. 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

DESCRIPTION:Speakers: HAEJUNG HWANG (LG Electronics)\nIn WebRTC-based appl
 ications\, 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.\n\nAs a result\, even when all frames are correctly delivered
 —for example\, in a 60fps video where all 60 frames reach waylandsink—
 frames may still be dropped in the gst_wayland_sink_show_frame function if
  the redraw callback is not received in time.\n\nOn webOS devices develope
 d by LGE\, we tested 60fps video playback using cloud gaming and observed 
 a frame drop rate of over 35% in waylandsink. In contrast\, when using non
 -WebRTC streaming methods with more consistent frame intervals\, playback 
 was smooth with almost no frame drops under the same conditions.\n\nTo add
 ress this issue\, we developed a GStreamer plugin called Video Frame Sched
 uler\, which sits between the video decoder and sink. It schedules frame d
 elivery at regular intervals\, simulating consistent frame timing. This re
 duced the frame drop rate to below 10%\, significantly improving playback 
 smoothness and reliability.\n\nIn this Lightning Talk\, we would like to s
 hare the challenges we encountered\, the design of our solution\, and enga
 ge with the GStreamer community to explore alternative or complementary ap
 proaches. We look forward to exchanging ideas and insights with fellow dev
 elopers and multimedia experts.\n\nhttps://indico.freedesktop.org/event/11

DESCRIPTION:Speakers: Axel Tobieson (Spiideo)\nWe wanted to serve content 
 immediately while waiting for the primary source to arrive. \nTo solve thi
 s\, we implemented a fallback mechanism using the `fallbackswitch` element
  combined with a custom `parsebinloop` element that continuously loops a s
 eekable file source with seamless timestamps\, making it appear as a live 
 stream.\n\nThe system maintains two sources: the incoming primary stream a
 nd the looping fallback. When clients connect\, they immediately receive t
 he fallback content. Once the primary source arrives\, we automatically sw
 itch to it and cleanly destroy the fallback pipeline. This ensures a stabl
 e RTSP server that always serves video\, eliminating the "waiting for stre
 am" experience.\n\nIn this lightning talk\, I'll quickly go over the chall
 enges of implementing seamless looping with continuous timestamps\, lesson
 s learned about building it\, and demo the system in action showing the sm

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

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

SUMMARY:A new era for GStreamer C++ bindings

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/

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

DESCRIPTION:Speakers: BUMİN KAAN AYDIN (HAVELSAN A.Ş.)\nIn our journey t
 o modernize and optimize our Video Management System (VMS)\, which current
 ly manages more than 100000 cameras from various manufacturers\, we've tra
 nsitioned the foundation of our live RTSP camera streaming from a custom F
 Fmpeg-based solution to GStreamer pipelines. Additionally\, we have reengi
 neered our offline video player\, replacing its FFmpeg-based framework wit
 h GStreamer to unify and enhance our media processing workflow.\nOur appli
 cation runs on Windows\, where we’ve leveraged GStreamer’s rapidly evo
 lving capabilities\, particularly the Direct3D 11 (d3d11) plugins\, to ach
 ieve efficient hardware-accelerated decoding and rendering. While the newe
 r Direct3D 12 (d3d12) plugins have gained maturity since we began\, our ne
 xt step is to investigate and integrate them into our application to furth
 er improve performance and scalability.\nIn this talk\, we will share our 
 experiences with migrating to GStreamer\, the challenges involved in adapt
 ing a complex VMS system\, our insights on using the d3d11 plugin suite on
  Windows\, and the lessons we've learned along the way. We believe our sto
 ry will resonate with others modernizing legacy systems and highlight the 
 versatility of GStreamer in developing high-performance multimedia applica
 tions.\n\nhttps://indico.freedesktop.org/event/11/contributions/462/
