Both, there's no specs hence the time needed to implement that is vastly 
raised. It would need to be worked out by trial and error and reverse 
engineering. There's better way to use the few development power 
available. Beside of that, it's still unclear if the mpeg4 acceleration 
available would be of real use or not (only h.263, no h.264). Even that 
is unclear without documentation.
