* constructing an RTP packet

* The RTP packet which we construct does not contain

* actual media data, but contains alphabets.

* Media streaming applications would replace this

* with actual media packets.

rtp_pkt_t pkt ;

pkt.v=2;

pkt.p=0;

pkt.x=0;

pkt.cc=0;

pkt.m=1;

pkt.pt=7;

pkt.seq=1;

struct timeval tv;

struct timezone tzp;

gettimeofday(&tv,&tzp);

pkt.ts=tv2dbl(tv);

pkt.csrcp=0;

pkt.xtnhdrp=0;

pkt.datap=(char*)malloc(9);

strcpy(pkt.datap,”abcdefgh”,8);

pkt.datalen=8;

i=0;

printf(“send an RTP packet? “);

fflush(stdin);

scanf(“%c”,&ec);

* The library automatically generates RTCP packets.

while((ec==’y’) (ec==’Y’))

{

i++;

if((ret= rtp_send(rd,&pkt))<0) break;

printf(“send another packet? “);

fflush(stdin);

scanf(“%c”,&ec);

}

if(ret<0)

printf(“rtp_send failed n”);

else

printf(“%d RTP packet(s) sent n”,i);

}
