The attach patch modifies v4l2-ctl -I to also output signal status as detected by the driver/hardware. This info is available in the status field of the data returned by VIDIOC_ENUMINPUT which v4l2-ctl -I already calls. The strings are copied from the v4l2 api specification and could perhaps be modified a bit to fit the application. Best regards Sigmund Augdal
