android: Set result metadata and EXIF fields based on request metadata
Set the following android result metadata: - ANDROID_LENS_FOCAL_LENGTH - ANDROID_LENS_APERTURE - ANDROID_JPEG_GPS_TIMESTAMP - ANDROID_JPEG_GPS_COORDINATES - ANDROID_JPEG_GPS_PROCESSING_METHOD And the following EXIF fields: - GPSDatestamp - GPSTimestamp - GPSLocation - GPSLatitudeRef - GPSLatitude - GPSLongitudeRef - GPSLongitude - GPSAltitudeRef - GPSAltitude - GPSProcessingMethod - FocalLength - ExposureTime - FNumber - ISO - Flash - WhiteBalance - SubsecTime - SubsecTimeOriginal - SubsecTimeDigitized Based on android request metadata. This allows the following CTS tests to pass: - android.hardware.camera2.cts.StillCaptureTest#testFocalLengths - android.hardware.camera2.cts.StillCaptureTest#testJpegExif Signed-off-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Jacopo Mondi <jacopo@jmondi.org>
