iOS Application [RTCPeerConnectionFactory sharedInstance] Crash

[krishna__venkata]

Hello Team,

While doing  streaming implementation functionality, we got unrecognised selector issue form ICS framework.

We did same as per the conference sample application. While publishing the local stream with conference client object, at creation of ICSLocalStream object its getting crashed with  RTCPeerConnectionFactory shared instance.

Here is the console logs :

2019-01-02 17:20:28.423179+0530 VideoConference[54377:6962689] -[NSError init] called; this results in an invalid NSError instance. It will raise an exception in a future release. Please call errorWithDomain:code:userInfo: or initWithDomain:code:userInfo:. This message shown only once.

frame type: 3

libc++abi.dylib: terminating with uncaught exception of type NSException

As we observe WebRTC framework does not contains any SharedInstance for RTCPeerConnectionFactory. In the ICS Framework only created one category for it. Only the sample conference application is running nothing more than it.

Please help us to resolve the crash.

Hello Team,

It's resolved, for ICS framework we need to add "-all_load" at Build settings-->Other linker flags .

Thanks

Hello, Team.

When I build sample ios project in ICS SDK, I get below error in this part.

    NSError *err=[[NSError alloc]init];

    _localStream=[[OWTLocalStream alloc] initWithConstratins:constraints error:&err];

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[RTCPeerConnectionFactory sharedInstance]: unrecognized selector sent to class 0x102691d38'

*** First throw call stack:

How Can I resolve this error?

krishina, you said you have fixed with "-all_load". Let me know clearly please.

[develop__full]

krishna, where did you add "-all_load" ? I have this bug when I try to get OWTLocalStream instance. Please let me know how to fix this bug?

[Jianjun_Z_Intel]

Hi,

[RTCPeerConnectionFactory sharedInstance] is defined in OWT category, so you cannot find it in WebRTC framework. Please link OWT/ICS framework.

Hi ,

  I have same issue when I using ios p2p demo on 4.3.1, app crash on [OWTLocalStream alloc] initWithConstratins:constraints.

   Please help me

hello ,team

when i added other linker flag "-all_load" , i get error " ld: 5378 duplicate symbols for architecture arm64" , the error is above with some part of it.

duplicate symbol '_SSL_SRP_CTX_free' in:

    ../CubeEngine/CubeEngine/WebRTC/OWT.framework/OWT(tls_srp.o)

    ../CubeEngine/CubeEngine/WebRTC/libsioclient_tls_no_verification.a(tls_srp.o)

    ../CubeEngine/CubeEngine/WebRTC/OWT.framework/OWT(cameravideocapturer.o)

    ../CubeEngine/CubeEngine/WebRTC/OWT.framework/OWT(CameraVideoCapturer.o)

it's seem like  some *.o file contain same symbol both in owt.framework and ibsioclient.a 

please let me know how to deal with it.

 thx all of you !

Were you able to fix the "duplicate symbols for architecture arm64"  error? I'm running into the same issue when I add `all_load` flag to the linker/
