DESCRIPTION:Speakers: Jacob Johnsson (Axis Communications)\nThe GStreamer 
 rtsp-server has provided configurations that ensured a low\nconnection fre
 quency but it was not possible to also receive up to date\ndecodable data.
 \n\nBy keeping an RTSP pipeline in the playing state after the initial DES
 CRIBE\nrequest\, the connection latency can be reduced. By conditionally f
 orcing\nkeyframes\, decodable frames are possible. This can be achieved by
  \nmanipulating the pipeline with pad probes\, a useful skill to master.\n

DESCRIPTION:Speakers: Michael Grzeschik ()\nUSB cameras are commonly used 
 in desktops and laptops for streaming video or\nparticipating in video con
 ferences. Thus\, USB is more or less the standard for\nconnecting a camera
  to a PC.\n\nLinux allows to turn hardware that has a USB device controlle
 r (UDC)\, for example the\nRapsberry Pi 4\, into a USB peripheral. The ker
 nel provides a number of \ndifferent USB gadgets to implement various USB 
 device classes. One of them is\nthe UVC (USB Video Class) gadget to implem
 ent an USB camera.\n\nHowever\, correctly configuring such a system and pa
 ssing a video stream to the\nUSB gadget is not that easy. Fortunately\, th
 e new uvcsink element allows you to\neasily stream an arbitrary GStreamer 
 video  pipelines into the UVC gadget and\,\nthus\, to any USB host system.
 \n\nMichael will show you how to prepare a system as a UVC gadget and stre
 am video\ndata to an UVC host using a simple GStreamer pipeline like "gst-
 launch-1.0\nvideotestsrc ! uvcsink". He will also give some insight into t
 he implementation\ndetails of the uvcsink element.\n\nhttps://indico.freed

DESCRIPTION:Speakers: Michalis Dimopoulos ()\nFlumes is an open-source ser
 vice we developed at Fluendo with the purpose of improving our QA process.
  It was designed with our multimedia playback/decoding products in mind. T
 he main goals of the service are\, to provide easy access to multimedia fi
 les of concrete specifications and a feeding mechanism to reproduction too
 ls or test automation frameworks. As such\, it becomes the connecting link
  between multimedia test collections and testing tools.\n\nIt consists of 
 diverse technologies that allow managing\, editing\, viewing and searching
  metadata information of multimedia content. It is developed in Python 3\,
  uses Glib and the gst-discoverer tool and stores metadata in an SQLite da
 tabase. The service runs as a daeamon on Linux\, constantly monitoring you
 r collection's path\, ensuring that the metadata database stays up-to-date

DESCRIPTION:Speakers: Rubén Gonzalez ()\nModern computers tend to have mu
 ltiple GPUs or a single GPU with several encoding cores\, but encoders can
  only use one of these cores. Parallelizing the encoding across multiple c
 ores can theoretically increase transcoding speeds linearly\, resulting in
  a 2x transcoding speed for VoD in a GPU with two encoding cores.\n\nThis 
 talk will present HyPE\, an Open Source GStreamer meta-encoder written in 
 Rust that can parallelize the encoding process across several encoding cor
 es to take advantage of all the available hardware resources.\n\nIts codec
 -agnostic design allows for seamless integration with a diverse range of c
 odecs\, making it a versatile choice for a wide variety of applications. I
 t is also hardware-agnostic to get compatibility with various systems\, in
 cluding NVIDIA\, AMD\, Intel\, and ARM architectures.  \n\nWe will showcas
 e the design of this plugin\, present the achieved results\, and examine t
 he limitations of this element\, along with potential areas for enhancemen
 t in future iterations.\n\nhttps://indico.freedesktop.org/event/5/contribu

 as Video Telephony\, Live Audio/Video streaming\, Video Conferencing e.t.c
 \, by supporting plugins which utilize both hardware accelerated media com
 ponents present in SoC and also supporting software based processing entit
 ies.\n\nTo ensure good overall user experience on such streaming media app
 lications\, there are various quality factors to ensure both at user-space
  and kernel-space level such as those related to maintaining Audio/Video S
 ync\, Latency optimization & Performance fine-tuning\, Detecting and avoid
 ing Video Frame Skip\, Audio distortion & Clipping\, maintaining Audio/Vid
 eo Quality and Error recovery e.t.c to ensure good overall user experience
 . The talk will go through above design considerations and also cover how 
 to prototype\, debug and optimize such low latency audio/video streaming a
 pplication.\n\nTaking a TI K3 based SoC as a reference example for prototy
 ping the video telephony use-case\, the talk will go through the basic bui
 lding blocks of the video telephony use-case covering relevant concepts in
 volved for each component from GStreamer and underlying Linux kernel frame

 out one interesting side of the GObject\, that allows us to use in runtime
  an already registered gstreamer element as a base class\, and therefore r
 egister a new gstreamer element that would contain certain modifications o
 r interceptions applied to the original one.\nIn particular this can be in
 teresting because it allows to intercept the behaviour of an element\, the
  code of which we can’t or don’t want to modify.\n\nThe technical side
  of the idea is quite simple\, you can find the explanation is a short cod
 e example here:\nhttps://github.com/aslobodeniuk/fun/blob/master/gobject-m

DESCRIPTION:Speakers: Jordan Yelloz ()\nThere are several existing media p
 layer frameworks based on client-side web technology that rely on Media So
 urce Extensions (MSE) API within web browsers. A new GStreamer library has
  implemented the MSE API in GObject C to make it possible for these player
 s to run on top of GStreamer without depending on a web browser library. S
 eparately\, since there is currently no complete solution within GStreamer
  to support the playback of DRM-protected media\, a new GStreamer API was 
 designed which maps closely to the Encrypted Media Extensions (EME) specif
 ication. Usage of the GStreamer MSE and EME APIs may be combined by applic
 ations\, though both APIs are designed to function independently.\n\nThis 
 presentation will discuss the WebKit origins of the MSE library\, its desi
 gn\, and the differences between the original implementation and the GStre
 amer library. The presentation will also provide an overview of the GStrea
 mer EME API design from two perspectives: one of a developer writing an ap
 plication designed to play protected media\, and the second of a developer
  making a content decryption module (CDM) available to GStreamer. Finally\
 , an end-to-end solution will be shown of a GStreamer application using th
 e EME API to play encrypted content using a commercially available CDM.\n\

DESCRIPTION:Speakers: Rubén Gonzalez ()\, Michalis Dimopoulos ()\nFluster
  is an open-source\, OS-independent\, testing framework written in Python 
 for multimedia decoder conformance. Its purpose is to check various implem
 entations against reference test suites with known and proven results. The
  decoders can be standalone executables\, as well as GStreamer- or FFmpeg-
 based. The tool was originally designed to check the conformance of H.265/
 HEVC decoders\, nowadays it also supports H.264/AVC\, H.266/VVC\, VP8\, VP
 9\, AV1 and AAC.\n\nFluster is composed of a CLI application that runs a n
 umber of test suites with the supported decoders and compares the checksum
  of the resulting outputs against reference ones. Its modular design permi
 ts someone to easily extend its functionality and also add more decoders a
 nd test suites.\n\nIn this talk we will provide an overview of Fluster and
  its functionalities covering the following topics:\n\n - Introduction to 
 Fluster\n - Running Fluster and analyzing the output\n - Extending Fluster
 : adding a new decoder or a new test suite\n - Next step: PyPI\, fluster p

DESCRIPTION:Speakers: Taruntej Kanakamalla (asymptotic.io)\nThe adoption o
 f WebRTC in the broadcasting/streaming industry has been hindered due to l
 ack of standard signalling that can be a simple plug and play model. With 
 introduction of [WHIP](https://www.ietf.org/archive/id/draft-ietf-wish-whi
 p-09.html) and [WHEP](https://www.ietf.org/archive/id/draft-murillo-whep-0
 2.html) specifications that is changing and the acceptance of WHIP/WHEP is
  evident with all major multimedia open source software implementing them.
 \n\nGStreamer already had the client side implementations WHIP/WHEP (whips
 ink and whepsrc) as of release 1.22 written in Rust. And the server side i
 mplementations are in progress.\n\nWith WebRTCSink and WebRTCSrc written t
 o support any signalling protocol as an interface separating from the sink
 /src functionality\, it has become easy to write all the client and server
  side implementations of WHIP/WHEP on top of WebRTCSink/Src. This also hel
 ps to leverage the support of both raw and encoded streams\, the congestio
 n control mechanism and every other new improvement that will be added in 
 WebRTCSink/Src in the future.\n\nMy talk is going to be an introduction on
  WHIP/WHEP protocols and the initial version of elements implemented in GS
 treamer using Rust and how they are evolving using the Signaller based des

  data streams. We discuss a new flexible and efficient design to address t
 hese problems\, without vendor or framework lock-in\, which can easily int
 eroperate with existing downstream approaches.\n \nTo achieve this goal\, 
 we have designed new framework-independent graph-based infrastructure usin
 g the existing GstMeta structure to store complex metadata and their relat
 ionships. We have also generalized the existing ONNX-based object detector
  to easily support many new inference models targeting a variety of hardwa
 re backends\, and have built a new OSD to visualize the generated analytic
 s metadata. Care has been taken to ensure efficient pipelines with support
  for batch processing and zero-copy. Finally\, we have built a bridge to n
 on-GStreamer land with a new cloud metadata sink that can send analytics r
 esults to cloud servers.\n\nWe will also present a demo at the end of the 
 talk showcasing a complex two-phase video analysis pipeline.\n\nhttps://in

DESCRIPTION:Speakers: Arun Raghavan (Asymptotic Inc.)\nWe all know that GS
 treamer is a (relatively) popular framework for processing media on consum
 er devices\, be it desktops\, robots\, cars\, phones\, and so on. However\
 , when we talk about server-side media processing\, arguably GStreamer is 
 still not quite as popular as it could be.\n\nDaily is a video/voice calli
 ng platform-as-a-service that offers a browser- and `libwebrtc`-based SDK 
 for to make calls using WebRTC. The service includes a number of features 
 that involve media processing in the backend such as recording\, live stre
 aming\, transcription\, media ingestion\, and SIP interoperability. All th
 ese services have been built using GStreamer.\n\nIn this talk\, we will wa
 lk through the overall architecture of these services\, and some interesti
 ng problems we came across while implementing them. We will then reflect o
 n what we’ve learned from using GStreamer in these scenarios and how we 
 might improve the experience for others who might want to tread this path.

DESCRIPTION:Speakers: Nicolas Dufresne (Collabora)\nHave you ever heard of
  frame tiling or frame buffer compression? These\, usually hardware-specif
 ic\, formats are commonly used behind the scene to make your CODEC and GPU
  hardware run a lot faster. Until now\, we have always tried to hide these
  formats from users. This would always lead to limitation and surprising s
 ide effects when the information was lost. Mis-negotiating these formats h
 as resulted in many visual corruption issues with our original VA API deco
 ders.\n\nIn this talk\, we will discuss how Linux DRM Modifier is fixing t
 hese issues. You will learn the new negotiation method and the tool that h
 as been developed to make this possible. You will learn how these formats 
 can be used and applied to DMABuf exchanges between various Linux componen
 ts like cameras\, VA and V4L2 CODECs\, GL Stack and of course Wayland and 
 the Linux Display drivers.\n\nhttps://indico.freedesktop.org/event/5/contr

 r open-source cross-platform framework allowing to build different types o
 f applications for web\, mobile\, desktop\, IoT or servers. It supports se
 veral programming languages\, being C# the most popular one.\nWith the cor
 rect integration\, GStreamer could become the reference framework for mult
 imedia applications in .NET\, bringing in new users to our community.\n\nO
 ver the last year\, the C# bindings have received some love after years of
  being un-maintained\, with several bug fixes\, updating the bindings to t
 he latest GStreamer release\, adding support for .NET\, and providing NuGe
 t packages.\n\nIn this talk\, we will present the current status of the C#
  bindings and how to use them to write GStreamer applications covering the
  following topics:\n\n - Status of the C# bindings\n - Nuget packages\n - 
 Using the GStreamer bindings\n - UI toolkits integration (MAUI\, Avalonia\

 ast four different APIs dedicated to multimedia encoding or decoding. Wine
 \, as a Free Software replacement of Windows\, implements most of those AP
 Is using GStreamer as a backend.\n\nIn this presentation I intend to talk 
 about our experiences working with GStreamer as a backend\, and its advant
 ages and disadvantages that we have found with it.\n\nI also intend to tal
 k about some larger unsolved problems we have that are specific to the cha
 llenge of implementing another API using GStreamer. These include:\n\n* su
 pporting zero-copy into application-provided buffers\,\n\n* matching appli
 cation expectations of synchronous decoding\,\n\n* consistently retrieving
  stream metadata\, especially optional stream metadata.\n\nIn the talk I i
 ntend to propose some potential solutions to these problems\, but more gen
 erally to raise them as questions for the GStreamer development community 
 to think about.\n\n\n[As as side note\, I've proposed this as a 45-minute 
 talk\, because I anticipate it can easily run that long. However\, if ther
 e is not time for a 45-minute talk\, I would be happy to give a talk in a 
 shorter time slot\, condensing the presentation if necessary.]\n\nhttps://

DESCRIPTION:Speakers: Julian Bouzas (Collabora)\nMPEG-5 part 2 LCEVC (Low 
 Complexity Enhancement Video Coding) is the latest standard by MPEG and IS
 O. However\, this one is different to typical codecs\, instead it acts as 
 a layer on top of existing codecs to improve their compression efficiency 
 (better quality at lower bitrates) and reduce transcoding compute requirem
 ents. The LCEVC data is carried along with metadata in the actual video st
 ream (e.g. in SEI messages for H264). By complementing other codecs rather
  than competing with them it rather circumvents the codec wars\, and is ch
 anging the video processing landscape we know.\n\nIn this talk\, from Coll
 abora and in collaboration with V-Nova who were the primary originators of
  the standard\, Julian will describe how LCEVC was implemented in GStreame
 r\, and the challenges he faced when integrating such an enhancement codec
  while keeping the GStreamer modularity and flexibility intact. He will al
 so describe why new LCEVC caps were introduced for autoplugging elements t
 o work\, and how the LCEVC enhancement data is passed through the base dec
 oder using a new type of GstMeta. When concluding the talk\, Julian will a
 lso talk about the future plans of the new LCEVC plugin for GStreamer\, an
 d will show a demo of a working GStreamer pipeline decoding LCEVC video.\n

DESCRIPTION:Speakers: Sanchayan Maity (asymptotic.io)\nWebRTC has become u
 biquitous as the technology powering various forms of video experiences on
 line. While Session Initiation Protocol (SIP) predated WebRTC by 12 years\
 , and had become the predominant protocol used to set up real-time media s
 essions between groups of users\, WebRTC looked to add real-time media i.e
 . audio\, video to every web browser without the need of a separate soft p
 hone client.\n\nWhile WebRTC has become the de-facto standard for real tim
 e communication on the Internet\, SIP still sees use in some scenarios\, s
 uch as bridging to phone networks (PSTN) and physical conferencing equipme
 nt.\n\nIn this talk\, we talk about how we went about connecting WebRTC an
 d SIP systems using GStreamer and SIP.js.\n\nhttps://indico.freedesktop.or
