hello every body.

I have build QT embeded 4.7.4(no X window) work with phonon gstreamer backend

in IMX53 quick start board.

 

but I can not play any video (use QT: demos/qmediaplayer )

 

the debug output here:

// this is output from QT program  
** (gst-launch-0.10:24385): WARNING **: ffmpegcsp0: size 11520 is not a multiple of unit size 10496
// this is output from QT program too
... a lot of output just like output with gplay
