Data:

CAMERA_EOK
The function call to the camera completed successfully.
CAMERA_EPERM
The function call failed due to a permission issue.
CAMERA_EAGAIN
The function call failed due to a temporary unavailable condition.

Try to call the function again.

CAMERA_EINVAL
The function call failed because of an invalid argument.
CAMERA_ENODEV
The function call failed because the specified camera was not found.
CAMERA_EMFILE
The function call failed because of a file table overflow.
CAMERA_EBADF
The function call failed because an invalid camera_handle_t value was used.
CAMERA_EACCESS
The function call failed because the necessary permissions to access the camera are not available.
CAMERA_EBADR
The function call failed because an invalid file descriptor was used.
CAMERA_ENODATA
The function call failed because the requested data does not exist.
CAMERA_ENOENT
The function call failed because the specified file or directory does not exist.
CAMERA_ENOMEM
The function call failed because memory allocation failed.
CAMERA_EOPNOTSUPP
The function call failed because the requested operation is not supported.
CAMERA_ETIMEDOUT
The function call failed due to communication problem or time-out with the camera.
CAMERA_EALREADY
The function call failed because an operation on the camera is already in progress.

In addition, this error can indicate that a call could not be completed because it was invalid or completed already. For example, if you called the camera_stop_video() function but the camera had already stopped recording video, this error code would be returned.

CAMERA_EBUSY
The function call failed because the camera is busy.

Typically you receive this error when you try to open a camera while the camera or its required resources are in use.

CAMERA_ENOSPC
The function call failed because the disk is full.

This typically happens when you are trying to start a video recording and less than the system-reserved amount of disk space remains.

CAMERA_EIO
The function call failed because of an Input/Output error.

This typically happens when a file I/O operation failed.

CAMERA_EEXIST
The function call failed because the entity trying to be created already exists.
CAMERA_EDEADLK
The function call failed because the camera is in a bad state.
CAMERA_EUNINIT
The function call failed because the Camera library has not been initialized.
CAMERA_EREGFAULT
The function call failed because the registration of a callback failed.
CAMERA_EMICINUSE
The function call failed because the microphone is already in use.
CAMERA_3ALOCKED
The function call failed because a 3A lock is active.
CAMERA_EOVERFLOW
The function call failed due to an internal overflow.
CAMERA_EHARDWARE
The function call failed due to a hardware fault with the camera.
