Adds a filter for which #GstDevice will be monitored, any device that matches
all these classes and the #GstCaps will be returned.
If this function is called multiple times to add more filters, each will be
matched independently. That is, adding more filters will not further restrict
what devices are matched.
The #GstCaps supported by the device as returned by gst_device_get_caps() are
not intersected with caps filters added using this function.
Filters must be added before the #GstDeviceMonitor is started.
