How to disable DTLS-SRTP feature in webrtc project

[xfengtes...@gmail.com]

Hi All,

As topic, I need to disable DTLS-SRTP in webrtc project for test, could you tell me how to? Thanks.

You can disable DTLS using "DtlsSrtpKeyAgreement" constraint set to false when creating peerconnection in Chrome.

Dear Vikas,

Thank you.

I'm developing P2P audio/video chat application based on WebRTC native api but not broswer. So i add the code as below item-A to disable DTLS-SRTP, and check dtls_enabled_ flag in webrtcsession.cc is false as below item-B. Could you tell me what my done is right to disable DTSL-SRTP feature and just RTP? 

item-A:

    webrtc::FakeConstraints setup_constraints;

    setup_constraints.AddMandatory(webrtc::MediaConstraintsInterface::kEnableDtlsSrtp,false);

    setup_constraints.AddMandatory(webrtc::MediaConstraintsInterface::kEnableRtpDataChannels,true);

    peer_connection_ = peer_connection_factory_->CreatePeerConnection(servers,

                                                                    &setup_constraints,

                                                                    NULL,

                                                                    this);

item-B:

  // Enable DTLS by default if |dtls_identity_service| is valid.

  dtls_enabled_ = (dtls_identity_service != NULL);

  // |constraints| can override the default |dtls_enabled_| value.

  if (FindConstraint(

        constraints,

        MediaConstraintsInterface::kEnableDtlsSrtp,

        &value, NULL)) {

    dtls_enabled_ = value;

  }

  LOG(LS_INFO) << "XF_SRTP: dtls_enabled_ is " <<dtls_enabled_;

You could fiddle with the SEC_REQUIRED flag somewhere in

https://code.google.com/p/chromium/codesearch#chromium/src/third_party/libjingle/source/talk/app/webrtc/webrtcsession.cc&q=sec_required&sq=package:chromium&type=cs&l=744

but you're basically on your own then.
