Hi:
I'm trying to send an AVI file, using a program similar to audiotx demo
program. My AVI file is 40,6 Mb long and contains 140 frames. I send them
fragmented, and fragments are 8000 bytes long. The problem is that: the
packets don't arrive to the other machine at time, and the delay is
increased more and more. I've tried to send the file reducing the rate, but
no way. Somebody can help me?
I send parts of my code.
/*TRANSMISOR*/
#define MAXTAM 8000
class cTransmisorAVI:public RTPSession, public TimerPort, public CImagen
{
public:
// Constructor.
cTransmisorAVI(char* filename, const InetHostAddress& ia,tpport_t port,
uint32 tstamp):CImagen(filename), RTPSession(InetHostAddress("0.0.0.0")),
packetspersecond(10)
{
........................................................................
setSchedulingTimeout(10000);
setExpireTimeout(100000);
if( !addDestination(ia,port) )
{
cerr << "I could not connect.";
exit();
}
setPayloadFormat(StaticPayloadFormat(sptPCMU));
startRunning();
uint16 tstampInc = getCurrentRTPClockRate()/packetspersecond;
uint32 period = 1000/packetspersecond;
TimerPort::setTimer(period);
..................................................................................
for (j = 0; j < (numpaqs - 1) ; j++)
{
p_sframe -> _numpaq = j+1;
p_sframe -> _postrunk = (MAXTAM - lcabecera) * j;
p_sframe -> _ldatos = (MAXTAM - lcabecera);
memcpy (p_sframe -> _datos, frame1, p_sframe ->
_ldatos);
putData(numframe*timestamp+j*tstampInc,(const unsigned char *)paq,lpaq);
Thread::sleep(TimerPort::getTimer());
TimerPort::incTimer(period);
frame1 = frame1 + (MAXTAM - lcabecera);
}
.........................................................................
main()
{
.............................
strcpy(dir, "158.227.66.63");
strcpy(tstamp, "32000");
strcpy(puerto, "3332");
cTransmisorAVI transmisor("trumpet01.avi", InetHostAddress(dir),
atoi(puerto), atoi(tstamp));
}
/*RECEIVER*/
#define MAXTAM 8000
class cReceptorAVI: public TimerPort, public CImagen, private RTPSession
{
...............................
void recibe(void)
{
................................
setExpireTimeout(1000000);
setPayloadFormat(StaticPayloadFormat(sptPCMU));
startRunning();
TimerPort::setTimer(PERIOD);
setCancel(cancelImmediate);
........................................
while(!fin)
{
const AppDataUnit* adu;
do
{
adu = getData(getFirstTimestamp());
if ( NULL == adu )
{
Thread::sleep(5);
}
else
cout << ".";
}
while ( (NULL == adu) || (adu->getSize() <= 0) );
memcpy (paq, (BYTE *) adu->getData(), adu->getSize());
delete adu;
cout << "." << flush;
// Let's wait for the next cycle
Thread::sleep(TimerPort::getTimer());
TimerPort::incTimer(PERIOD);
......................................................
}
.....................................................
}
main()
{
...........................
cReceptorAVI *receptor = new cReceptorAVI(local_ip, puerto);
// Run it.
receptor->recibe();
cin.get();
..............................................
}
Thanks for help
