Encapsulation:

const int encapsulation_port = port_number;
if (!pgm_setsockopt (sock, IPPROTO_PGM, PGM_UDP_ENCAP_UCAST_PORT,
&encapsulation_port, sizeof (encapsulation_port)) ||
    !pgm_setsockopt (sock, IPPROTO_PGM, PGM_UDP_ENCAP_MCAST_PORT,
&encapsulation_port, sizeof (encapsulation_port)))

Data ports:

addr.sa_port = port_number; /* data destination port */
addr.sa_addr.sport = DEFAULT_DATA_SOURCE_PORT;

So, both the same with encapsulation enabled.
