Getting the best out of small hardware encoders in moving sources

Some small, cheap, light linux boards have hardware video codecs that can produce 1080p @30pfs h264 at very low power consumption - making them idea for streaming low latency content from moving sources such as droids and vehicles

The challenges of hybrid meetings

Events and meetings have changed a lot in the past few years. What typically envisaged people meeting and engaging in some location around the world (possibly with a handful of active remote participants), first changed to a fully virtual participation, and is now moving towards a more seamless interaction between many on-site participants, and possibly as many remote participants instead. This presentation will explain how Meetecho handled this (double!) transition, and will provide some information on how it helped actual hybrid events (e.g., IETF and RIPE) finally take place for the first time with the help of ad-hoc tools (and Janus!).

RTC in Finance - How Bloomberg uses WebRTC to connect Finance Professionals

The Bloomberg Terminal is used by more than 350,000 finance professionals around the globe.

WebRTC & Video Delivery application security - what could possibly go wrong?

WebRTC is often considered to be secure by default - with most security concerns being around IP address leakage which is more of a privacy issue than anything. Well, I have news for you - the applications and infrastructure that handles WebRTC can be attacked. It may indeed have various types of security vulnerabilities which are often overlooked. This presentation is based on experiences gained through security testing of WebRTC applications with anecdotal stories to illustrate the dangers. We will also take a peek at Video Delivery mechanisms such as RIST and SRT and discuss what could possibly go wrong there too!

Telecom Testing - A fresh take on a forgotten trade

Telecoms used to be obsessive about testing - but that's a thing of the past. The growing complexity of realtime communication services, paired with the grinding halt of the evolution of relevant test tools, leaves RTC developers and operators in the dry. In this talk, we'll show some modern approaches to automated telecom testing, using open source tools you already know and love.

This Little MOQ Maneuver's Gonna Cost Us 51 Milliseconds

OTT live sports has led sports broadcasting to a new level. Yet, there are still some challenges. For example, nobody wants to hear a neighbor’s cheers when a goal is scored before seeing it on the screen, making low-latency transport and playback indispensable. Synchronization among all viewing devices and social media feeds is also essential. The IETF recently started developing a QUIC-based low-latency delivery solution for media ingest and distribution. The Media-over-QUIC work is still in its infancy but could be a game-changer. In this talk, we will discuss the architectural design issues and present preliminary results from our implementation.

Will GPT rescue machine voice interfaces.

ML based voice interfaces have been kicking around in hype cycle for 6 or 7 years. Its is a painstaking task to build a decent one, and, lets face it users have stopped expecting much so it is hard to get excited about the return on effort needed to build them. This talk implements one live onstage in 20mins with a GPT rather than hand crafted dialog training and tries to figure out how much of a game-changer this approach will be.

Sex, Lies and Video Tapes: The Truth Behind Your CDN Logs

Everybody lies. In this nasty world of end-to-end video delivery, all the involved stakeholders lie to achieve their own results. But where is the truth? The truth lies right in front of your eyes, and it’s always been there - in your CDN logs.

Having spent almost a decade in this industry, working my fingers to the bone with FFMpeg commands, and ending up crying drunk a few times in Vegas & Amsterdam being agonised over high latency, glitches, and stalled video errors…my rocky journey made me learn a few things about CDNs, and now it's time to share my industry expertise in CommCon.

During this session, I'll share some tips on understanding the logs' info, ways of predicting some bad behaviours in your CDN network, and how to fix the issues before our viewers face the dreaded 400s.

Follow me on this logging journey where you'll discover some insider secrets of the video industry, and most importantly learn how to predict stream issues thanks to our wonderful CDN logs. Don't trust anybody except your headers!

The History of The Future of Communications.

( Looking back at 2033 and what happened to Telecom over the past 10 years due to advances in: AI, Chatbots, 6G and Blockchain.)

In this talk, I'll discuss how modern technology has blurred the lines between traditional real-time communications (phone calls!) and traditional broadcast media (video!)

Let's write a Web Platform Test

Cross browser compatibility got a lot better in recent years. There is a huge set of browser APIs which work very very similar in all modern browsers. The implementations are so close that many of the CLIs that come with todays frontend frameworks set up tests that only run in one browser or no browser at all.

But unfortunately things are still very different when it comes to media APIs. There are a lot of APIs which are still new and work in progress. They often don't work as promised by the specifications and they often work differently from browser to browser or they don't work at all. It's not uncommon to run into a browser bug.

Reporting a bug is the mandatory first step to get it fixed. And therefore it's best to have a reproducible test case which demonstrates the bug. Creating this test case is often the tricky part. But once it's done it can also be turned into a Web Platform Test.

Web Platform Tests are a set of tests that verify browser implementations. All big browser vendors got together to create a large corpus of tests that they run across all browsers. The results are used often to show off spec compatibility. Web Platform Tests are for example used by the yearly Interop projects. But it's an open source project. Anyone can contribute a test.

Adding your test ensures visibility. It will lower the compatibility score if it fails. It will probably also increase the motivation to get it fixed. And last but not least it will make sure that the same bug never pops up again in any of the tested browsers.

Let's improve browser compatibility together one test at a time.

Less is More: Human Factors and Product Death Spirals

Frequently, developers overestimate humans. Particularly when making design choices. This can be the big mistake that dooms a project… We’re going to discuss well-invested engineering efforts like benchmarking and optimizing minimalistic data flows. When is a user interface too flexible...? We’ll also talk about how to avoid tragedies like giving users (or their devices) too much credit.

Sub-Second Latency Streaming Technologies and Applications

Many people believe that WebRTC is the only option regarding sub-second latency streaming due to its low latency and widespread browser support. However, other options may be better suited for specific use cases, especially when considering feedback from the open-source community and video cloud service customers.

Depending on the specific use case, WebRTC may be the best choice for web browsers, while SRT may be better suited for broadcasting devices. However, combining both may be necessary in some cases, and RTMP plus WebRTC can also provide sub-second latency.

In this discussion, I will explore the most effective solutions for these use cases using SRS technology to provide sub-second latency streaming services. Additionally, I will introduce the SRS project and community, which has existed for ten years and has over 20,000 stars on GitHub, making it a valuable resource for developers worldwide.
