QML MediaPlayer with timer to reconnect streaming

[iodev]

Good morning,

I programmed a QML MediaPlayer streaming an IP camera. I coded a timer to reconnect if the video signal is lost. I tried this on Linux and it works perfectly when I disconnect the camera it emits the signal "OnError" but when I try this on Windows (with 5.15.2 MinGW 64 bit) the code doesn't emit the signal "OnError" after disconnecting the camera and I don't know the reason. If anyone has any idea about what could be the difference between Windows and Linux about this code I would be very grateful. Thanks in advance.
