Hi,


I have a requirement that to play a video using mplayer in an application(AppA). But the code for mplayer should be in another application(AppB). That means AppA is my main application and I have to run mplayer code from backend.

I am using Qt 4.7 version in Linux environment. In AppB I have hidden the widget in main function as below
Widget w;
w.hide();

And calling a playvideo function for every 5 mins in AppB. In playvideo function I am using system fucntion to play video as below.

void Widget::playvideo()
{
system("mplayer /path/to/the/video.avi");
}


And I am running AppB in backend (using exe name with & symbol) when AppA started. Here I am able to play video but video is blinking and some part of AppA ui is visible in middle.

But my requirement is to hide AppA ui while playing video from AppB. So can you please tell me how to solve this.
