What steps will reproduce the problem?
1. Checkout latest webrtc code
2. Build peerconnection sample
3. Run peerconnection sample (server and 2 clients)

What is the expected output? What do you see instead?
Expected to be able to do video call, but no video (local and remote) on initiator side, and no local video on receiver side (only remote video seen).

What version of the product are you using? On what operating system?
Windows 7

Please provide any additional information below.
There is no problem when test with server_test.html

Two log files attached. Both are logged on same machine by same peerconenction_client app. One is recorded when acting as initiator, the other is as receiver.

Is there any update on this issue?
Thanks.

Just checked out latest webrtc code and tried again, the issue is still there.

The issue could be fixed by adding two lines to "PeerConnectionImpl::SignalingMessage()" in peerconnectionimpl.cc, but I'm not sure if the fix is correct or not, could anybody help to take a look? Thanks.

Here is the code:
-----------------------------------------------
bool PeerConnectionImpl::SignalingMessage(
    const std::string& signaling_message) {
  // Deserialize signaling message
  cricket::SessionDescription* incoming_sdp = NULL;
  std::vector<cricket::Candidate> candidates;
  if (!ParseJsonSignalingMessage(signaling_message,
                                 &incoming_sdp, &candidates)) {
    return false;
  }

  bool ret = false;
  if (GetReadyState() == NEW) {
    // set direction to incoming, as message received first
    session_->set_incoming(true);
    ret = session_->OnInitiateMessage(incoming_sdp, candidates);
    // MY FIX - start
    if(ret)
      ret = session_->Connect();
    // MY FIX - end
  } else {
    ret = session_->OnRemoteDescription(incoming_sdp, candidates);
  }
  return ret;
}
