CameraBin error: "Internal data stream error."

Hello Folks,

Device : RPi 3
What I'm trying to achieve:
Roll over 4 USB camera displaying their video stream.

Right know, I got in a single thread, a state machine that roll over all the four camera (every 10 sec I switch) but time to time I got that internal data stream error (I have like 10 other thread for other module).

I got the exact same error with the qt camera example when I want to switch camera.

It might because, I got some library that are missing?
All the gstreamer relatives library that I installed are:

    if( m_camera.data() != NULL)

        res = -1;
    }

    return res;
}

The start of the camera is done in the worker class.

When the result is hitten every 10 sec, I reset for the new camera:

void popupavancement::handleResults_emi(int res)
{

    // Arrêt caméra
    m_camera->stop();

    if(res == 2)
    {
        rollCamera();
    }
    else
    {
        workerThread_emi.quit();
        workerThread_emi.wait();

        stop = true;
        qCInfo(logger) << QString("Arrêt du test d'émission des caméras avec le résultat: %1").arg(res);
    }
}

If you need any other information.

Thanks in advance,
