Hello everyone!
I would be very grateful if someone could help me out with the issue below, I'm
new to live555.
I've got nine audio streams that I'm pulling in via ffmpeg and then re-encoding
them to AAC-LC and pushing to udp://127.0.0.1:port_num?pkt_size=1316 (where
port_num is replaced by respective port number) The first stream is being
pushed to port 10000, the second one to 10001, third one to 10002, etc.
Example for first stream:
ffmpeg -i remotestream [...codec options...] -f mpegts
udp://127.0.0.1:10000?pkt_size=1316
I've modified testOnDemandRTSPServer.cpp as shown below. (taken from
live555-latest.tar.gz downloaded today - 8 March 2015)
I launch my ffmpeg instances & the rtsp server and connect to it via
VLC/another rtsp client.
It works, I do hear the audio stream, however the issue is that as soon as one
client connects, the RTSP server uses 100% of the CPU.
As soon as the client disconnects, the CPU usage falls back to normal. Any idea
of what could be wrong?
#include "liveMedia.hh"
#include "BasicUsageEnvironment.hh"
UsageEnvironment* env;
Boolean reuseFirstSource = False;
Boolean iFramesOnly = False;
int main(int argc, char** argv) {
TaskScheduler* scheduler = BasicTaskScheduler::createNew();
env = BasicUsageEnvironment::createNew(*scheduler);
RTSPServer* rtspServer = RTSPServer::createNew(*env, 8554, NULL);
if (rtspServer == NULL) {
*env << "Failed to create RTSP server: " << env->getResultMsg() << "\n";
exit(1);
}
char const* descriptionString
= "Session streamed by \"MyRTSPServer\"";
int NUM_STREAMS = 9;
char const* streams[] =
{"stream1","stream2","stream3","stream4","stream5","stream6","stream7","stream8","stream9"};
int port = 10000;
for(int i=0;i<NUM_STREAMS;i++)
{
const char* streamName = streams[i];
const char* inputAddressStr = "127.0.0.1";
portNumBits inputPortNum = port; port++;
Boolean const inputStreamIsRawUDP = True;
ServerMediaSession* sms = ServerMediaSession::createNew(*env, streamName,
streamName,descriptionString);
sms->addSubsession(MPEG2TransportUDPServerMediaSubsession::createNew(*env,
inputAddressStr, inputPortNum, inputStreamIsRawUDP));
rtspServer->addServerMediaSession(sms);
char* url = rtspServer->rtspURL(sms);
*env << "\n\"" << streamName << "\" stream, from a UDP Transport Stream
input source \n\t(";
if (inputAddressStr != NULL) {
*env << "IP multicast address " << inputAddressStr << ",";
} else {
*env << "unicast;";
}
*env << " port " << inputPortNum << ")\n";
*env << "Play this stream using the URL \"" << url << "\"\n";
delete[] url;
}
env->taskScheduler().doEventLoop(); // does not return
return 0; // only to prevent compiler warning
}
Thanks!
