apps: cam: Add option to set stream orientation
Add a '--orientation|-o' option to the cam test application to set an orientation to the image stream. Supported values are the ones obtained by applying flips to the camera sensor: - rot0: no rotation - rot180: rotate 180 degrees - flip: vertical flip - mirror: horizontal flip Signed-off-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com> Reviewed-by: David Plowman <david.plowman@raspberrypi.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
