Connect to apprtc.appspot.com #8

Hello. Does this framework connects to apprtc.appspot.com? I got the error setting Remote description. The error returned is:

Error Domain=org.webrtc.RTCPeerConnection Code=-1 "SessionDescription is NULL." UserInfo={NSLocalizedDescription=SessionDescription is NULL.}

Session description for method looks fine, except first line of RTCSessionDescription:offer duplicate. That duplicate appeared after parsing server response via [[RTCSessionDescription alloc] initWithType:[RTCSessionDescription typeForString:type] sdp:sdp] method.

or maybe you can advice what server works fine with latest release?

Hi.

Does this framework connects to apprtc.appspot.com?

I don't know, but it should, because as I remember Google uses that signaling server for their demo AppRTCMobile app. I only used our internally developed signaling server for rooms and SDP exchange.

Please check this comment in order to see how I set remote description in my app. And please ask for such help in discussion group, it is a community and there are more experienced people.

thanks, figured out it myself, but you pointed to right direction.

@multybuq, I am facing the same issue. Could you please let me know how you resolved the issue.

multybuq commented 7 years ago

@mohangslab083 if you are using apprtc ios demo client with this webrtc framework, you have to modify RTCSessionDescription+JSON class, because problem is there. I just parsed webrtc source files for proper RTCSessionDescription generator/parser and connection methods

DSaurabh commented 7 years ago

@multybuq i am facing similar issue. i have checked out latest webrtc code and able to compile framework with webrtc script. Please share the source code for required changes.

multybuq commented 7 years ago

@DSaurabh I've already changed all my classes for custom signaling server, so i can not share what you need. I just can point you to reason of your issue. You should check all of your session description categories and offer/answer session generating and exchanging. BTW, ADRAppClient.m contains all you need. It may connect to appRTC.com properly. So please get webrtc source code and check sample code.

DSaurabh commented 7 years ago

@multybuq i was able to use some old library and old syntax which is working fine for me. In new set of API i am facing this issue. Since appRTC app is based on old api set it is not useful for new API set and latest binaries. Link : https://chromium.googlesource.com/external/webrtc/+/master/webrtc/sdk/objc/Framework/Headers/WebRTC/RTCPeerConnection.h

Old API: [peerConnection setLocalDescriptionWithDelegate:(id) self sessionDescription : rtcDesc];

With new API: //To init SDP (instancetype)initWithType:(RTCSdpType)type sdp:(NSString *)sdp //To setLocalDescription
