Former Shadow CTO Develops Revolutionary Open Source Streaming Technology
In this video, Jean-Baptiste Kempf, former technical director of Shadow, the French cloud gaming service, shares his journey after the company's bankruptcy and failed acquisition. He decides to start over by developing a new open source technology called Kyber, which shatters speed records in video streaming. Kyber is a revolutionary technology that transmits an image in just 8 milliseconds, compared to 60 milliseconds for other technologies. This speed is faster than the time it takes for your brain to blink. Kempf explains that although initially developed for gaming, this technology has much broader applications, including drone control, robotics, and telemedicine. Kempf recounts his journey and the technical challenges he had to overcome to develop Kyber. He explains that the technology works on any operating system and is based on open source libraries like VLC and FFmpeg. By modifying these libraries to optimize transmission speed, Kempf and his team have significantly reduced latency. They also used the Quick protocol, based on UDP, to improve performance by reducing latency and efficiently managing packet loss. The video highlights the various applications of Kyber, particularly in robotics and telemedicine. Kempf mentions that the technology has been successfully tested for controlling robots and drones and could also be used for remote surgical operations. He emphasizes the importance of constant latency and video quality for these critical applications. Kempf also explains the technical challenges related to latency and video quality. He mentions that the total latency is composed of device latency, screen-to-video transformation time, network time, and video playback. By optimizing these different aspects, Kyber achieves significant latency reduction. The video concludes with a demonstration of Kyber in action, with Kempf playing a video game using a virtual reality headset. He explains that the technology is still in development but has already shown promising results. He also mentions that Kyber is open source, allowing the community to contribute and improve the technology. In conclusion, this video offers a fascinating glimpse into the challenges and innovations in low-latency video streaming. It shows how open source technologies can be used to create revolutionary solutions with applications far beyond gaming.
