Why it exists
Streamers and screen-recording creators told the same story on forums and in reviews: OBS Studio is powerful but heavy to download, easy to misconfigure, and costs frames in the game. BriseStream's mission is to replace OBS Studio for a PC streamer, while being far smaller to download and far cheaper on the game. Each of the three goals, complete, light to download and invisible in game, is mandatory, and none may be bought at the expense of another.
Status, stated plainly
- In development; version 1.0 is in preparation. There is no public download yet.
- Windows first, then Linux and macOS.
- The goals are targets, not results: a download of 25 MB or less, 1 % or less FPS lost, under one second to open the window, no GPU work when idle. The 1 % goal is not met in every setup; the measured numbers and their limits are on the performance page.
How it is built
- Written in Rust, with a Slint user interface that holds no GPU context of its own.
- Capture through Windows (no injection into games), hardware encoders through the drivers (NVENC, AMF, QuickSync), crash-safe Matroska recording, RTMP(S), SRT and WHIP outputs.
- Heavy parts (browser source, VST3, NDI, virtual camera) are optional modules downloaded on first use and cost nothing while off.
- Decisions that are not obvious are recorded as public ADRs in the repository.
