Hi Guys,

Do you have any solution for this issue?

[weidong_sun]

Hi,

   Try to modify camera HAL like following

(1) Open UvcDevice.cpp

(2) find these code:

Then change "capCount < 2" to "capCount <10", then re-compile the HAL and try to capture image.

Regards,

Weidong

Hi,

Thank you for your reply.

I can't find the code

in my UvcDevice.cpp,
