Hi manfeng!

Did you solver your issue? I think that I have a similiar problem :(

I solved this problem. I commented a line of code in the _uvc_process_payload_iso function in the stream. file to preview the image. I forgot the specific line of code here. I have a packaged .SO library file. If necessary, leave an email and I will send it to you. But I am not sure if it will help you.

Thank you very much for your answer manfeng!

I see. Every help is welcome! :)

And nothing happens :(

.so libs has been sent to your email, hope it helps you.
