How to Integrate External USB Camera for Live Streaming with LiveKit SDK (Kiosk Device Use Case)

[maksood5010]

Hi,

I'm currently working on an Android kiosk application that does not have a built-in camera, so I'm using an external USB camera connected via OTG. For handling the USB camera, I'm successfully using this library:

The camera feed is rendered correctly onto a TextureView or SurfaceView using this library.

Now, I want to live stream the USB camera feed to AWS IVS (RTMPS endpoint) using the LiveKit SDK or any recommended approach.

My main questions:
How can I integrate the USB camera feed with the LiveKit SDK?

Is there a way to pass the external camera stream (from AndroidUSBCamera) into LiveKit as a video source?

Can I provide a custom video track from a SurfaceView or TextureView?

Is there any recommended way to capture frames from the USB camera and push them to LiveKit's video track system?

If LiveKit does not support this directly, is there an alternative method using your SDK that allows pushing raw video frames to a broadcast service like AWS IVS via RTMPS?

Any guidance, code examples, or best practices would be greatly appreciated.

Thanks in advance!

If you can render the frames to a surface, then implementation of a VideoCapturer should be pretty simple.

You can reference our BitmapFrameCapturer implementation. I think everything aside from the pushBitmap function can be used. It'd just be up to you to hook up the surface to your camera, and it should work from there.
