Hi all.

now i try to use usb_cam package of bosch_drivers stack with the
latest libavutil.

however, i got the following errors when i compile it:
[ 66%] Building CXX object src/libusb_cam/CMakeFiles/usb_cam.dir/usb_cam.o

i found we need to put
#define __STDC_CONSTANT_MACROS
before include stdio.h.

i also attatched the patch.
