here is an a demonstration of how to configure vlans and ssid on a auto-ap , what i dont understand is when i configure the ssid under (interface dot11radio0) and the vlan under that command , why do i need to configure sub-interfaces for the "fastethernet" and the "dot11radio0" if i already configured it under the "interface dot11radio0" , why do i need the "encapsulation dotq x" ? and what is bridge-group ?

If you want to use multiple SSID with multiple vlan, then you have to configure subinterfaces on Radio interfaces (in both Radio 0 & Radio 1 if you want to use both 2.4GHz & 5GHz band) & Ethernet interfaces.
AP simply bridge wireless traffic to wired interface using these sub-interfaces. To specify which radio sub-interface traffic to map to ethernet sub-interface, a Bridge-Group number (1-255) is used.
Bridge-Group 1 always used for native vlan traffic & usually used for AP management.

That is correct. Here are some guides to show you how to configure that:
