getting started : MPP

hello,
I am starting to test target board(FireFly-RK3128) by the instructions.test environment: prebuilt-ubuntu-image

kernel version:3.10.0
prebuilt filesystem

I downloaded prebuilt-ubuntu-image, and the target board loaded firmware in successfully.
But I could not find any other resources or examples related to MPP(video codec) on the system (ubuntu image, kernel version:3.10.0).
Is there any available MPP examples on this target(FireFly-RK3128, kernel 3.10.0) ?

Next, I read MPP wiki from rockchip to test codec functionality, and I tested as following steps :

build mpp by buildroot
run mpp test applications on target board(ubuntu) :
Is the following log normal ? If not, what can I check ?
