V4L2_EVENT_PRIVATE_START is used in g_uvc.h but is defined in videodev2.h, which is not included and causes a compiler warning: linux/usb/g_uvc.h:15:28: error: ‘V4L2_EVENT_PRIVATE_START’ undeclared here (not in a function) #define UVC_EVENT_FIRST (V4L2_EVENT_PRIVATE_START + 0) Include videodev2.h in g_uvc.h.
