Adds a filter for which gstreamer.Device will be monitored, any device that matches
all these classes and the gstreamer.Caps 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 gstreamer.Caps supported by the device as returned by Device.getCaps are
not intersected with caps filters added using this function.
