Openmax related errors

[rookie]

I've tried to do video encoding and compiled this sample code:
android-4.0.1_r1.2/hardware/ti/omap4xxx/domx/test/sample_proxy/
test_sample_proxy.c

This code is downloaded from google and is running on Galaxy Nexus
(Omap4460) platform. However, there are errors below:
1. OMX_AllocateBuffer() return OMX_ErrorNotImplemented
2. OMX_UseBuffer() return OMX_ErrorUndefined
In 'android_omap_tuna_3.0_mr0/drivers/rpmsg/rpmsg_omx.c' at line
110

Does this mean I forgot to include something or I might be using wrong
version of some module?

Thanks,
Rookie

Sadly there's no response on this one.
Should I provide other information to make it clearer?
