Crash in recording call, when pjmedia_conf_connect_port executed SIGABRT in pjsip

问题

Earlier when I was using pjsip 2.7.1 It was working fine. The call recording was perfect. but now I have installed pjsip 2.9. It is crashing on pjmedia_conf_connect_port. SIGABRT because of pjsua_var.mconf. I don't have any idea when it allocated in pjsip. Please explain and help to solve this issue.

Thanks in advance

I tried to create a media conference before it was using in the recording. but it ended up with no audio.

+(void)startRecordingForCalleeId:(NSString *)calleeId andCallId:(int)callid
{


    NSLog(@"start recording...........");
    Recording *sipRecording = [[SPCoreDataManager sharedManager]createBlankSipRecordingForCalleeId:calleeId];
    NSString *filePath = [[SPFileManager sharedManager] pathForFile:sipRecording.fileName];


    SPAppDelegate *appDelegate = (SPAppDelegate *)[[UIApplication sharedApplication] delegate];
    appDelegate.objectID = sipRecording.objectID;
    pj_str_t fileName = pj_str([filePath UTF8String]);
    status = pjsua_recorder_create(&fileName, 0, NULL, -1, 0, &recorder_id);
    NSLog(@"status issss-->%d",status);



    [[NSUserDefaults standardUserDefaults] setInteger:recorder_id forKey:@"recording_id"];
    [[NSUserDefaults standardUserDefaults] synchronize];

    NSLog(@"recordder id id--->%d",recorder_id);
    NSLog(@"recording is for start recording is--->%d",app_config.rec_id);

    //status = pjsua_recorder_create(&fileName, 0, NULL, -1, 0, &app_config.rec_id);

    if (status != PJ_SUCCESS)
    {
        pjsua_perror(__FILE__, "error dll_startAudioCapture from pjsua_recorder_create", status);
    }
    else
    {
        //app_config.rec_port = pjsua_recorder_get_conf_port(app_config.rec_id);
        app_config.rec_port = pjsua_recorder_get_conf_port(recorder_id);

        PJ_LOG(5, (__FILE__, "dll_startAudioCapture recId=%d confPort=%d", app_config.rec_id, app_config.rec_port));

        pjmedia_conf_connect_port(pjsua_var.mconf, callid,app_config.rec_port, 0);//working for the 1st call
        pjsua_call_get_info(callid, &call_info); //callid


        pjsua_state state = pjsua_get_state();

Please help

if (ci.media_status == PJSUA_CALL_MEDIA_ACTIVE) {
                userCall.hasConnected = true
                pjsua_conf_connect(ci.conf_slot, 0)
                pjsua_conf_connect(0, ci.conf_slot)
                if recorderPortId != PJSUA_INVALID_ID.rawValue {
                    pjsua_conf_connect(ci.conf_slot, recorderPortId)
                }
            }

We should be connecting the conf port after it connects the sound port. Even if you connect port after creating a recorder connect it here. You will have a clear voice recorded.

I am putting my android Pjsip Call recoding code for your reference it might help you.

public void record(String recordingCallerNumber) {
        CallInfo ci;
        try {
            ci = currentCall.getInfo();
        } catch (Exception e) {
            return;
        }

        CallMediaInfoVector cmiv = ci.getMedia();
        for (int i = 0; i < cmiv.size(); i++) {
            CallMediaInfo cmi = cmiv.get(i);
            if (cmi.getType() == pjmedia_type.PJMEDIA_TYPE_AUDIO &&
                    (cmi.getStatus() ==
                            pjsua_call_media_status.PJSUA_CALL_MEDIA_ACTIVE ||
                            cmi.getStatus() ==
                                    pjsua_call_media_status.PJSUA_CALL_MEDIA_REMOTE_HOLD)) {
                // connect ports
                try {
                    File root = Environment.getExternalStorageDirectory();
                    File mainFolder = new File(root.getAbsolutePath() + File.separator + "call_record");
                    if (!(mainFolder.exists() || mainFolder.isDirectory())) {
                        mainFolder.mkdirs();
                        mainFolder.setExecutable(true);
                        mainFolder.setReadable(true);
                        mainFolder.setWritable(true);
                        MediaScannerConnection.scanFile(getApplicationContext(), new String[]{mainFolder.toString()}, null, null);
                    }

                    audioMediaRecorder = new AudioMediaRecorder();
                    am = currentCall.getAudioMedia(i);
                    audioMediaRecorder.createRecorder(mainFolder.getAbsolutePath() + File.separator + recordingCallerNumber + ".wav");
                    am.startTransmit(audioMediaRecorder);
                    MyApp.ep.audDevManager().getCaptureDevMedia().startTransmit(audioMediaRecorder);
                    MyApp.ep.audDevManager().getCaptureDevMedia().startTransmit(am);
                    am.startTransmit(MyApp.ep.audDevManager().getPlaybackDevMedia());

                } catch (Exception e) {
                    System.out.println("Failed connecting media ports" +
                            e.getMessage());
                }
            }
        }
    }
