VideoExample no image but sound

hello hello

i am trying to run ofAndroidVideoExample on an ICS tablet.
the app loads fine but only plays the sound, no video. the image displayed is an assemblage of glitch.

LogCat throws some errors (see below) indicating that CedarXNativeRenderer isn’t happy. Though I couldn’t figure out why. Can anyone point me to a direction?
Thank you!

Android 4.0.4 IceCreamSandwich
Allwinner A13 Chip with MALI 400 GPU
The preloaded videos do play…

LogCat throws these errors:
