RTC.ON 2025 STARTS IN LESS THAN
3 WEEKS!
Karolina Kulig
MARKETING MANAGER @ SOFTWARE MANSION
There it is – the last edition of the RTC.ON Newsletter before the conference! We can't wait to welcome you in our Kraków office once again, listen to all the exciting presentations and have fun together on a boat party. And, for those who can't join us this year – don't worry! Just like in the previous years, there will be a free live stream from both conference days (available on Sept 18 on rtcon.live).
What's in store for this year:
- Sept 17, 2025: DAY 0 – Workshop day
Excited to learn more about multimedia development? Choose one of this year's workshops: Multimedia 101, Local LLMs & STT with ExecuTorch in C++, WebRTC on Kubernetes - From Pods to Production.
- Sept 18, 2025: CONFERENCE DAY 1
Let’s start the fun! We have a bunch of great talks planned for this day, but that’s not all. During the afternoon coffee break, Arin Sime from WebRTC.Ventures will talk to some of our speakers and give you an extended glance at their talks. We finish off Day 1 with drinks and snacks on the Pokłady boat located just by the Vistula river.
- Sept 19, 2025: CONFERENCE DAY 2
On the second day, we’ll continue with more video & AI talks. The conference will end with beers and chats in the office – a perfect time to get to know each other more and discuss all the presentations from the past two days.
Since the idea for the RTC.ON Newsletter originally came from the conference itself, we wanted to make a small gift for you, the RTC.ON Newsletter Community. The RTC.ON tickets are now available only in the standard pricing, but with the code RTCONNEWSLETTER you can buy your ticket for an Early Bird price (-30% from the current prices). Thank you for being with us every month! :)

PyroWave: a video codec for Ultra-Fast Game Streaming
A hobbyist has developed PyroWave, a video codec designed to enhance low-latency game streaming on local networks. The project utilizes discrete wavelet transforms for very high transmission speeds, recording 0.13 ms for 1080p and 0.25 ms for 4K encoding. PyroWave focuses on efficiency and speed with GPU support. Reading the article you can learn a lot about video coding in general.

OWhisper tool for Local Speech-to-Text Capabilities
OWhisper is a tool that integrates Speech-to-Text capabilities both in real-time and batch processing. It can be used for local prototyping or to deploy larger models on privately-hosted infrastructure. It’s good to see more interest in running models locally.
