WebRTC peer-to-peer connection

Question

I am implementing a connection between a WebRTC peer-to-peer connection for audio calls using C ++.

I have two threads _worker_thread and _signaling_thread . Now when I try to create _peerConnectionFactory by calling the webrtc::CreatePeerConnectionFactory() method, my application crashes. How can I make it work?

 _signaling_thread.reset(new rtc::Thread()); if(!_signaling_thread->Start()) { printf("_signaling_thread is Failed"); return; } _worker_thread.reset(new rtc::Thread()); if (!_worker_thread->Start()) { printf( "_worker_thread is Failed"); return; } _peerConnectionFactory = webrtc::CreatePeerConnectionFactory(_worker_thread.get(),_signaling_thread.get(),NULL,NULL,NULL); 

This is the backtrace I get

 * thread #15: tid = 0x17e516, 0x00000001008d5674 MyAPP`rtc::MessageQueue::Get(rtc::Message*, int, bool) + 816, stop reason = EXC_BAD_ACCESS (code=1, address=0x100000038) * frame #0: 0x00000001008d5674 MyAPP`rtc::MessageQueue::Get(rtc::Message*, int, bool) + 816 frame #1: 0x00000001008e5fb0 MyAPP`rtc::Thread::ProcessMessages(int) + 100 frame #2: 0x00000001008e5e44 MyAPP`rtc::Thread::PreRun(void*) + 88 frame #3: 0x0000000199337b3c libsystem_pthread.dylib`_pthread_body + 156 frame #4: 0x0000000199337aa0 libsystem_pthread.dylib`_pthread_start + 1

After looking at the PeerConnection samples located inside the WebRTC source code, I always initialize the SSL modules before creating such streams:

 bool Core::Init() { rtc::InitializeSSL(); rtc::InitRandom(rtc::Time()); rtc::ThreadManager::Instance()->WrapCurrentThread(); _signalingThread = new rtc::Thread(); _workerThread = new rtc::Thread(); _signalingThread->SetName("signaling_thread", NULL); _workerThread->SetName("worker_thread", NULL); if (!_signalingThread->Start() || !_workerThread->Start()) { return false; } _peerConnectionFactory = webrtc::CreatePeerConnectionFactory(_signalingThread, _workerThread, NULL, NULL, NULL).release(); return true; }
