Functions

func DetectError

func DetectError(osInfo OSInformation, daughterboardName, driverName string) error

DetectError checks daughterboard and camera setup to determine our best guess of what is wrong with an unsuccessful camera open

func ValidateSetup

func ValidateSetup(deviceName, daughterboardName, driverName string, err error) error

ValidateSetup wraps an error from NewWebcamSource with a more helpful message

Types

type CameraInformation

type CameraInformation struct {
	// map of daughterboard name to I2C bus names
	Daughterboards map[string][]string // e.g. "i2c-30", "i2c-31"
	// map of camera product name to object-file camera driver
	Modules map[string]string // e.g. "ar0234.ko"
}

CameraInformation contains information about the daughterboards and camera modules that are supported.

type OSInformation

type OSInformation struct {
	Name   string // e.g. "linux"
	Arch   string // e.g. "arm64"
	Kernel string // e.g. "4.9.140-tegra"
	Device string // e.g. "NVIDIA Jetson AGX Xavier"
}

OSInformation contains information about the OS that the camera is running on.

func DetectOSInformation

func DetectOSInformation() (OSInformation, error)

DetectOSInformation pulls relevant OS attributes as an OSInformation struct Kernel and Device will be "unknown" if unable to retrieve info from the filesystem returns an error if kernel version or device name is unavailable
