Qt 4.5.1 embedded error Phonon+Gst+Glib on arm9

Hello,

i'm using qt-4.5.1 on my arm9 (i.MX27 device) and i compiled it succesfully, with the phonon plugin and gst backend all was ok.

In my rootfs i have glib 2.0 compiled.

When i use de qmediaplyer, i run the application, and it was an error with the Glibobject. I cannot see any video.

But, if i use gstreamer with the console, all was ok and i can to see my video, but when i use it with phonon there is an error with glib.

Can anyone help me?

I have to compile again glib for my qt application?
Which glib needs gstreamer backend???

I need another libs for use gstreamer backend?

thanks.
