rds-ctl --help (return code: 0)
Usage:
General/Common options:
--all display all device information available
-D, --info show driver info [VIDIOC_QUERYCAP]
-d, --device=<dev> use device <dev>
If <dev> starts with a digit, then /dev/radio<dev> is used
default: checks for RDS-capable devices,
uses device with lowest ID
-h, --help display this help message
-w, --wrapper use the libv4l2 wrapper library.
--list-devices list all v4l radio devices with RDS capabilities
Tuner/Modulator options:
-F, --get-freq query the frequency [VIDIOC_G_FREQUENCY]
-f, --set-freq=<freq>
set the frequency to <freq> MHz [VIDIOC_S_FREQUENCY]
-T, --get-tuner query the tuner settings [VIDIOC_G_TUNER]
--tuner-index=<idx> Use idx as tuner idx for tuner/modulator commands
--freq-seek=dir=<0/1>,wrap=<0/1>,spacing=<hz>
perform a hardware frequency seek [VIDIOC_S_HW_FREQ_SEEK]
dir is 0 (seek downward) or 1 (seek upward)
wrap is 0 (do not wrap around) or 1 (wrap around)
spacing sets the seek resolution (use 0 for default)
--list-freq-bands display all frequency bands for the tuner/modulator
[VIDIOC_ENUM_FREQ_BANDS]

-b, --rbds parse the RDS data according to the RBDS standard
-R, --read-rds enable reading of RDS data from device

--wait-limit=<ms> defines the maximum wait duration for avaibility of new
RDS data
<default>: 5000 ms
--print-block prints all valid RDS fields, whenever a value is updated
