+Some pipeline managers have support for selecting the sensor mode. This consist
+of locking the sensor into a specific resolution/format in order to obtains a
+specific field or view, quality or get access to different frame duration
+ranges. Applications can read the enumerate mode through the ``sensor-modes``
+properties and select (or filter) the selected mode using ``sensor-mode``
+property. As an example, an application that needs 60 frame per second can
+ensure this with:
+.. code::
+    gst-launch-1.0 libcamerasrc sensor-mode="sensor/mode,framerate=60/1" ! \
