Hi,
Thanks a lot for your help.
Now I created one GUI application which has a combobox displaying all .264
files . and if we select a file and press play button ,
I am making a system call to executable
system("./app.out -v filename ") ;
In my application (./app.out) I am using video1 driver for dispalying. So
when i Press play button, executable starts running but display crahes.
I think QT uses fbdev(framebuffer) driver to display the GUI.
When I checked with Imageviewer application (made system call to this
executable) with my GUI. images are getting displayed properly.
Imageviewer application is using fbdev drivers.
So how I can solve problem?
Is there anyway to modify QT to use video driver?
Thanks,
Mahalakshmi.
