Hi Ameba Support,

I am trying and searching for a best wired method to stream amb82 mini camera stream to raspberry pi 3b+ from last some days. But unable to find or successfully get the stream on rasp. So please help me to have a best method using which i can stream camera feed to my rasp. For now i have tried couple of methods like UVC but unsuccessful. Please help me with methods and explained sources.

Thank you,
Varun

Hi @Varun_Chopra , since raspberry pi 3b+is running Linux, and portplayer does not have linux. You may try to follow this guide to install guvcview. Remember to flash the code into amb82 using this example and connect the usb otg, you may refer to this guide.

After install guvcview open up go to video control, on deivce tab select USB UVC CLASS and click restart. Finally, change the camera output tab to h264. Thank you.

Thank you very much, KaiFai_Y, for your response and support. I truly appreciate it.
I tried the solution, but now I believe there is a different issue possibly related to power. As soon as I start accessing the stream from the AMB82 Mini, the /dev/video device disappears.

I have powered the Raspberry Pi using a reliable source and the AMB82 with an external supply as well, but the issue persists. When listing devices, /dev/video0 appears, but once I try to access the stream, it seems there is not enough power, and the device disappears.

At this point, I think I need to explore using the RX and TX pins instead of USB. If you have any resources or guidance on that, I would really appreciate your help.

Hi @Varun_Chopra, for the AMB82, once the code has been flashed, you may remove the micro USB cable and connect only the USB OTG port to the Raspberry Pi. However, if you encounter power-related issues, please ensure that sufficient power is supplied to maintain a stable stream.

Currently, the supported streaming features include RTSP and UVC. If you plan to use other methods, you may need to implement them yourself.

You can refer to the AMB82 documentation for all available examples and guides.

Thank you.
