dear friends,
i am trying to receive a data stream over
network socket and play that using sound stream
functions . i have two structure
struct IP
{
int tot_length;
int ipbits;
int identifier;
int flags;
int ttl;
int checksum;
long int sourceip; //has to be converted
long int destip;
long int opt;
struct UDP
{
int sourceport;
int destport;
int length;
int checksum;
struct RTP
{
int sequence;
int PT;
int rtpbits;
long int t_stamp;
long int ssrc;
long int csrc;
Int16 dataBuff[1024];
}rtp;
}udp;
}*ipsend,*iprecv;
---------------------------------------------------
typedef struct {
SndStreamRef soundStream;
Int16 dataMemP[1024];
} BufPtrs;
static BufPtrs Recbufptrs,Playbufptrs;
the first one is for the packet which i am reciveing
and second for playing it. i am using follwing fun
iprecv = (struct IP *)MemPtrNew(sizeof(struct IP ));
if((recbytes=recvfrom(sockfd,iprecv,sizeof(struct IP
), 0,(struct sockaddr *)&rec_addr, &addr_len)) != -1)
{
MemMove(&(Playbufptrs.dataMemP),&(iprecv->udp.rtp.dataBuff),BUFSIZE);
err = SndStreamStart(Playbufptrs.soundStream);
}
else
{
FrmAlert(RecAlert);
}
free(iprecv);
}
But the application is getting hanged while executing
recvfrom function , some problem in receiving.
A similar program for recording and sending data is
working fine.
Any help in this regard will be greatly apprecited.
Regards
rahul
