Hi,
I have the following error
imagenet-camera: failed to capture frame
imagenet-camera: failed to convert from NV12 to RGBA
when executing the imagenet_camera example
I did change the #define DEFAULT_CAMERA from -1 to 0
#define DEFAULT_CAMERA 0 // -1 for onboard camera, or change to index of /dev/video V4L2 camera (>=0)
then in the build folder
make
sudo make install
