General/Common options:
--all display all information available
-C, --get-ctrl [,...]
get the value of the controls [VIDIOC_G_EXT_CTRLS]
-c, --set-ctrl =[,=...]
set the value of the controls [VIDIOC_S_EXT_CTRLS]
-D, --info show driver info [VIDIOC_QUERYCAP]
-d, --device use device instead of /dev/video0
if starts with a digit, then /dev/video is used
Otherwise if -z was specified earlier, then is the entity name
or interface ID (if prefixed with 0x) as found in the topology of the
media device with the bus info string as specified by the -z option.
-e, --out-device use device for output streams instead of the
default device as set with --device
if starts with a digit, then /dev/video is used
Otherwise if -z was specified earlier, then is the entity name
or interface ID (if prefixed with 0x) as found in the topology of the
media device with the bus info string as specified by the -z option.
-E, --export-device use device for exporting DMA buffers
if starts with a digit, then /dev/video is used
Otherwise if -z was specified earlier, then is the entity name
or interface ID (if prefixed with 0x) as found in the topology of the
media device with the bus info string as specified by the -z option.
-z, --media-bus-info
find the media device with the given bus info string. If set, then
-d, -e and -E options can use the entity name or interface ID to refer
to the device nodes.

the subset of the N-dimensional array to get/set for control ,
for every dimension an (, ) tuple is given.
-w, --wrapper use the libv4l2 wrapper library.
--list-devices list all v4l devices. If -z was given, then list just the

specified by the -z option.
--log-status log the board status in the kernel log [VIDIOC_LOG_STATUS]
--get-priority query the current access priority [VIDIOC_G_PRIORITY]
--set-priority
set the new access priority [VIDIOC_S_PRIORITY]
is 1 (background), 2 (interactive) or 3 (record)
