HI,
I try to make a streaming video client server application using thr TWsocket
component.
I think i have some probleme with handling all the data that is comming on the
client part. On my server part, I have a callback function that if fired as
soon as i have a video frame is ready. this card is a mpeg4 compressor card, so
the data fram is variable. From 248 bytes to 30K or 40K. So I send it in UDP.
This server is a multi streaming server I can stream up to 4 channel. since i
have only 1 callback for all the channel i can't do it in a thread (i think).
So i do this every thime i received a frame:
I have put a TWsocket on the form.
frmTestCarteDSPR->udpServer->Proto = "udp";
frmTestCarteDSPR->udpServer->Addr =
frmTestCarteDSPR->infoConnection[channelNum].ipAddr; // ip addr to the remote
host
frmTestCarteDSPR->udpServer->Port =
frmTestCarteDSPR->infoConnection[channelNum].ipPort; // remote port
frmTestCarteDSPR->udpServer->Connect();
size = 65535;
setsockopt(frmTestCarteDSPR->udpServer->HSocket, SOL_SOCKET , SO_SNDBUF,
(const char *)&size, sizeof(size)); // change the socket buffer to 65535
frmTestCarteDSPR->udpServer->Send((unsigned char *)DataBuf,Length); // send
data
frmTestCarteDSPR->udpServer->Close(); // close the socket
I would like to know if this is a good way of doing it ??? is ther a simple way
or a better way of doing this ?
on the client part, i do this in the udpClientDataAvailable
maxlength = udpClient->RcvdCount;
//debugStream << "data received = " << maxlength << endl;
frame = new uint8_t[maxlength];
while(byteread < maxlength)
{
Len = udpClient->Receive(&frame[byteread],1460);
byteread += Len;
}
// I continue the job for displaying the video.
is there a better way of doing this ? is it possible to receive all the data
without looping ?
regards
Jonathan
