QtGStreamer - QGlib::connect

junf1024

I meet some Error Tips when I use "QGlib::connect" to connect QGst::BusPtr with my slots function.

Although the slots function have worked successfully, the app always print some error message like that after slots :

Error during invocation of closure connected to signal "message::eos" from object "" : "One of the arguments of the signal was not a valid GValue. This is most likely a bug in the code that invoked the signal."

my codes like that:

QGst::BusPtr bus = m_pipeline->bus();
bus->addSignalWatch();
QGlib::connect(bus, "message", this, &MainWindow::onBusMessage );

Has anyone ever had the same problem?

When I use QGlib::connect at other Class such as QWidget...
This error has disappeared!

Maybe... I should not use it at QMainwindows ?
