Hi,
I'm facing this problem, the app which get webcam screenshot and encode them
in h263 works and feed live with an UDP socket (addr 127.0.0.1 port 1234). I
don't know why the bytestream seems not arriving to the live server..
Could anyone help me or give any hints?
I report my server code below
#include "liveMedia.hh"
#include "BasicUsageEnvironment.hh"
#include "GroupsockHelper.hh"
FramedSource* videoSource;
void afterPlaying(void*);
int main()
{
TaskScheduler* scheduler = BasicTaskScheduler::createNew();
UsageEnvironment*env = BasicUsageEnvironment::createNew(*scheduler);
//Create our sink variables...
char const* destinationAddrStr = "192.168.55.102";
const unsigned char ttl = 1;
const Port rtpPort(8888);
struct in_addr destinationAddress;
destinationAddress.s_addr = our_inet_addr(destinationAddrStr);
Groupsock rtpGroupsock(*env, destinationAddress, rtpPort, ttl);
//Create our sink...
//RTPSink* videoSink = MPEG1or2VideoRTPSink::createNew(*env,
&rtpGroupsock);
RTPSink* videoSink =
H263plusVideoRTPSink::createNew(*env,&rtpGroupsock,56,0);
if(videoSink == NULL){
*env << "Unable to create sink \n";
exit(1);
}
*env<<"RTPSink created\n";
//Create our source variables...
char const* srcAddrStr = "127.0.0.1";
struct in_addr srcAddress;
srcAddress.s_addr = our_inet_addr(srcAddrStr);
const Port udpPort(1234);
Groupsock udpGroupsock(*env, srcAddress, udpPort, ttl);
//Create our source...
FramedSource* input = BasicUDPSource::createNew(*env, &udpGroupsock);
if (input == NULL) {
*env << "Unable to open source \n";
exit(1);
}
*env<<"Input created\n";
//Create our framer...
videoSource = H263plusVideoStreamFramer::createNew(*env,input);
*env<<"framer created\n";
//Start to stream the data....
videoSink->startPlaying(*videoSource, afterPlaying, NULL);
env->taskScheduler().doEventLoop();
*env<<"END";
return 0;
}
void afterPlaying(void*) {
Medium::close(videoSource);
}
Thanks a lot for the kind help!
