Hi, I'm not experiencing this issue at the moment, what device are you using? Some devices may just not be supported. Would you try running this and see?https://github.com/jiangdongguo/AndroidUSBCamera?tab=readme-ov-file#demo

@chenyeju295 Hello I have the same error "DId not find frame", the app detect that camara is conected but no image shown in the app, can you can generate apk for flutter? I want to discard that my code is not compiling wrongly.

I have tried two different cameras, one works and the other tells me that "campera opned error: unsupported preview size".

Hello! I've updated the code to view device information,supported preview sizes, you can try it and see if it's a camera device issue.

Thank you for your earnest help, I tried the demo app from AUSBC earlier and it bugs as the same. So I'm searching for other devices. I'll run your code later and give you feedback as soon as possible. Thank you again!

A fun situation is, after limiting the constant MAX_FPS in CustomCameraUVC.kt, the dropping rate of fps is quite slowing down. (I just notice it was moved in a function as a variable in the latest code).

You're welcome ☺️, his parameters will be different for different devices, so compatibility is still a huge challenge.

Hello!, Thanks for the update, a basic web cam works well for me, but for the camera I have "inskam315w", it doesn't work, it tells me "get camera preview size failed"
