Detailed Description

A class which stores all devices in an object.

This object is a singleton initialized automatically by detecting all devices in the system, The devices are detected iterating over all files in the device directory.

This singleton can be accessed as vidl_v4l2_devices::all() Note that you can work with devices without using this singleton, because you can create a vidl_v4l2_device directly from the file name. However, it is better to look for the device in this singleton using directly de card name.
