You might wanna set the configuration, at least to set ARGB for transparency
over video (assuming an STB kind of device). Please run dfbinfo.
Maybe this is enough:
layer->SetOpacity( layer, 0 );

Common mistake to use both primary surface and primary layer.

You might wanna set the configuration, at least to set UYVY.

Not needed.
Just work with primary and second layer surface.
