Stream's Livestreaming product now supports 4K at 60fps over WebRTC. We wanted to share some details about the choices that made this possible, from codec selection to VMAF-driven bitrate targets to the adaptive bitrate ladder that keeps it watchable for everyone.

We recently open-sourced the Stream Video ESP32 SDK, an SDK that lets an ESP32-S3 or ESP32-P4 join a Stream Video call, capture camera and microphone input, encode H.264 + Opus in real-time, and publish it over WebRTC. Someone on a browser or mobile device can then see and hear the ESP32 live. If you're

TLDR; Live commerce is a trillion-dollar market, led by China's $680B in 2023 sales but growing fast in the U.S. with a 36% jump projected by 2026.

Of course, all those platforms, and really the entire concept of video streaming and video chat, are only

Vision Agents is a new, open-source framework from Stream that helps developers quickly build low-latency vision AI applications. The project is completely open-source and ships with over ten out-of-the-box integrations, including day one support for leading real-time voice and video models like OpenAI Realtime and Gemini Live. Text-to-speech, speech-to-text, and speech-to-speech models are also natively

We've all been in the situation where we're typing out a message in an app and think, "actually, I just need to call this person." In-app voice and video calling is how you add this functionality to your product. With in-app video, your users can talk to each other without jumping to a different app.

Picture this: Netflix serves over 15 billion hours of content monthly, Twitch handles an average of 2.55 million concurrent viewers (with peaks above 3.8 million during major events), and Zoom facilitates billions of meeting minutes, all relying on fundamentally different streaming technologies under the hood.
