I build apps for artists and their fans, from native modules to the last pixel.

Last week: my first Nitro module.
This week: it's a VisionCamera 5 output. 📡

<Camera outputs={[stream.cameraOutput]} />

That's it. Your VisionCamera app can now go live on YouTube, Twitch or any RTMP/RTMPS server.

Built my first package with Nitro Modules! 🔥

react-native-nitro-rtmp: RTMP/RTMPS live streaming for React Native.
Camera, mic, overlays. Video frames never touch JS.

Thanks @mrousavy, @margelo_com(@callstackio) for building Nitro!

Huge thanks to @mrousavy and @margelo_com: VisionCamera 5's output API made this a clean fit, and Nitro made the native side a joy to write. 🙏

[Brian YOO @bhyoo99]

Under the hood, per platform:

iOS: AVCaptureVideoDataOutput in VisionCamera's session → Metal compositor
Android: CameraX Preview straight into a GL SurfaceTexture

Then camera + overlay layers on the GPU, hardware H.264/AAC, and a sans-IO RTMP core shared by both.

@mateusz1913 Are you gonna support react-native-web too?

[Brian YOO @bhyoo99]

@pontusab @expo @languine_ai THX for the amazing product!

[Brian YOO @bhyoo99]

@sebastienlorber That name is so familiar to me 🤣

[Brian YOO @bhyoo99]

@VadimNotJustDev It looks like there's not enough gradation. Make sure to add a gradation with a flashy color😂

[Brian YOO @bhyoo99]
