Hi Boyuan,

as Emil wrote as well try to add some commit messages to the set. For 
this patch something like the following should do it:

Allow to specify more parameters in the encoding interface which where 
previously just hardcoded in the encoder.

Additional to that we need to reorder the patches a bit. First the 
interface changes, then the OMX changes to fill in the previously 
hardcoded values, then the radeon backend changes and then last the 
VA-API changes to use the new interface.

Additional to that a few notes below.

Why can't this be inferred from the encoded picture type?

I thought we wanted to drop the ref_pic_list handling for now. If that 
is still the case please drop those fields here as well.
