OpenAI introduces Codex

As Sam Altman announced in his tweet on X: “it is a software engineering agent that runs in the cloud and does tasks for you, like writing a new feature or fixing a bug.” Codex right now is only available to users on the ChatGPT Pro Plan and ChatGPT Team Plan. Check out the blogpost for more info!

WHIP becomes an RFC 9725

While this was quite a while ago, we haven’t posted here that WHIP is officially an RFC document. Also, Dan Jenkins steps up as WHEP editor to help push it over the finish line.

Chatterbox - a new open-source TTS model licensed under MIT

Key features include zero-shot voice generation, intensity control or watermarked outputs. They also claim to be better than ElevenLabs, but we would take this with a grain of salt. Check out demo samples and the comparison to ElevenLabs.

MoQ - Application First

An authentic take from a video engineer, who decided to transition from his role at Discord, to embark on his own endeavor. He is creating a startup with MoQ (Media over QUIC) at the core. We wish him the best of luck, and hopefully in a couple months, we will see a sick demo from him.

How to play RTSP in the browser?

RTSP is a rather old-fashioned media streaming protocol. However, it is still the standard in some specific scenarios, for example it is widely used by IP cameras. Now, if you want to play such stream directly in your browser, there no way to do so. Well, how can we work around that then? The solution might not be all that surprising.

RTC.ON CFP is officially closing today! This means that the Super Early Bird ticket sale (50% off) comes to an end. Now is your last chance to grab a deal like no other: use code news10 to get an extra 10% off 💸

The code is valid until Friday, June 6.

🚀 WHAT: RTC.ON Conf 2025

🕕 WHEN: 17-19 September 2025

📍 WHERE: Kraków, Poland

We've recently released vk-video, a library for hardware video decoding using Vulkan Video.

The library integrates with wgpu, so you can decode video using the GPU's hardware decoder and then sample the decoded frame in a wgpu pipeline. A major advantage of vk-video is that only encoded video is transferred between the GPU and the CPU, the decoded video is only kept in GPU memory. This is important, because decoded video is huge (10GB for a minute of 1080p@60fps). Because of that, vk-video should be very fast for programs that want to decode video and show it on the screen.

Right now, vk-video only supports decoding AVC (aka H.264 or MPEG 4 Part 10), but work on an AVC encoder is progressing very quickly. We also hope to add support for other codecs later on.

ElixirConf 2025 is behind us, but what a conference it was!

Software Mansion marked its presence at many levels. Mateusz Front announced Popcorn (YouTube presentation) - a library that enables execution of Elixir code within web browsers, Feliks Pobiedziński took the stage to talk about the release of Boombox 0.2.0 showing how to add a multimedia layer to your Phoenix project, and Krzysztof Nalepa jumped in on lighting talks to present LiveDebugger.

But that's not all that there was to the conference! As a Streaming Partner, we broadcasted the whole conference using our recently polished project: Glitch.tv, a streaming software written in pure Elixir.

PS. If you're excited about seeing the live side of our streaming projects, get ready for what's to come! We've just finished another project – live streaming of the biggest React Native and Expo conference, App.js, using Fishjam. We'll talk about it more in the next edition – stay tuned!

We hope you enjoy the RTC.ON newsletter as much as we do. It's great to see all of you joining us each month for a little multimedia walk through – thanks!
