I want to use the AMB82-Mini with further functionality developed in a more powerful debian board (RPi / NanoPi / OrangePi, etc..). I need to access the H264 stream on these boards via USB or any other wired connection, after being processed for object detection and motion detection with the bounding boxes. How can I achieve this? The USB OTG functionality is not documented in Arduino docs. I am open to other suggestions too. ---

Hi @Vignan_Tej, This feature is still not available yet. To use AMB82-Mini as an ai powered usb webcam, this feature will have to be ported. You may raise this as a feature request in our Github repo. Thank you. ---

Hi @Vignan_Tej, The Arduino SDK prerelease version (4.0.8-build20240805) now supports USB UVC feature. As it is a prerelease version (dev), the SDK could be unstable. Do let us know if you have encounter any issues. To use the Arduino SDK prerelease version (4.0.8-build20240805), kindly input [https://github.com/ambiot/ambpro2\_arduino/raw/dev/Arduino\_package/package\_realtek\_amebapro2\_early\_index.json](https://github.com/ambiot/ambpro2_arduino/raw/dev/Arduino_package/package_realtek_amebapro2_early_index.json) under preference in Arduino IDE and install 4.0.8-build20240805. ---

Hi @Vignan_Tej , We do not have this example, however you may refer the following guide to implement it.

Hi Pammy, Thanks for the directions. I am not able to get any output from the USB UVC Example. This is the console log output.

Hi @Vignan_Tej , May I know which media player you are using? I suggest that you can use PotPlayer. If you using PotPlayer, please use the following setting to start stream. ![image](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/2X/6/688129f2613813d9b6b82f171ab718038ea058a0.png) ---

I was using windows default camera application. It was being recognised as USB UVS Class, but black screen and the stream did not start. I am planning to get the stream through go2rtc to stream it over webrtc. ---

Currently we have not test on windows default camera application yet. there are chances that the example is not supported for windows default camera application yet. There are also some updates for usb uvc, [Update USB UVCD APIs and CI workflow · ambiot/ambpro2\_arduino@509c46a · GitHub](https://github.com/ambiot/ambpro2_arduino/commit/509c46a09719ec3ac495c8c1af8bfb07cb618f16) You may need to modify the following in Arduino SDK to get more format type supported. - cores/ambpro2/video\_drv.c - cores/ambpro2/video\_drv.c - src/UVCD.cpp - src/UVCD.h ---

> [@Pammy](#): > > USB UVC: [USB – UVC Device – Realtek IoT/Wi-Fi MCU Solutions](https://www.amebaiot.com/en/amebapro2-arduino-usb-uvc/) Does it have Controls in camera UI when using it as usb-cam ? I studied from the video presentation that brightness, contrast, exposure and gray mode can be set from the IDE but will the Camera app UI pick it up and can we be able to manually set it from UI instead of IDE command?

Hi @spikerguy which camera UI are you referring to? If you are creating your own UI, you can refer to [VideoStream Class – Realtek IoT/Wi-Fi MCU Solutions](https://www.amebaiot.com/en/rtl8735b-arduino-api-videostream/) to develop and program your UI. We does not provide UI; it can only be set manually from the IDE. ---

Hi @Pammy, I am not able to get the video stream using ffmpeg. Any specific configuration I should use?
