cam: Implement OptMetadata
Implement support for the new '--metadata' option by printing the value of each metadata entry associated with a completed Request. As sample of the output, running on raspberry pi, looks like the following: 3050.205672 (30.01 fps) stream0 seq: 000033 bytesused: 720000 ScalerCrop = (0x2)/3280x2460 ExposureTime = 13969 AeLocked = true DigitalGain = 1.000721 Lux = 771.204224 ColourGains = [ 1.561101, 1.629698 ] ColourTemperature = 4289 SensorBlackLevels = [ 4096, 4096, 4096, 4096 ] ColourCorrectionMatrix = [ 1.691066, -0.599756, -0.091317, -0.437452, 1.983766, -0.546314, -0.083429, -0.722407, 1.805836 ] AnalogueGain = 2.000000 SensorTimestamp = 3050205672000 3050.238999 (30.01 fps) stream0 seq: 000034 bytesused: 720000 ScalerCrop = (0x2)/3280x2460 ExposureTime = 13969 AeLocked = true DigitalGain = 1.000709 Lux = 771.232422 ColourGains = [ 1.560868, 1.630029 ] ColourTemperature = 4289 SensorBlackLevels = [ 4096, 4096, 4096, 4096 ] ColourCorrectionMatrix = [ 1.691081, -0.599726, -0.091362, -0.437497, 1.983627, -0.546130, -0.083420, -0.722523, 1.805943 ] AnalogueGain = 2.000000 SensorTimestamp = 3050238999000 Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se> Reviewed-by: Hirokazu Honda <hiroh@chromium.org> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>
