I had the same problem with an sh based chip, but I didn't find a way to
clone the display from one output to another using the DirectFB API.
So I made it myself inside a custom gfxdriver.
The driver exposes only one screen to directfb, but 2 encoders, 2 mixers and
2 outputs.
This lets the user define the resolution on each output.

Unfortunatly the driver is proprietary, I can provide the source code as an
example...
