I have crated rootfs with Yocto Rocko . I am running Qt application on it with X11 support.

What I observed booting log :
RandR extension missing
matchbox: Cant find a keycode for keysym 269025056
matchbox: ignoring key shortcut XF86Calendar=!$contacts

matchbox: Cant find a keycode for keysym 2809
matchbox: ignoring key shortcut telephone=!$dates

matchbox: Cant find a keycode for keysym 269025050
matchbox: ignoring key shortcut XF86Start=!matchbox-remote -desktop

And main observation is new rootfs {created with Rocko}is not supporting video playing feature with qt app.
But old rootfs {created with Krogoth} was supporting Video playing.

Did Imissed any Package in rootfs ?
Please guide me for this Solution.

Note : for Both Rootfs I have same Packages mentioned in local.conf
