I may be wrong but my impression is that AVVideoEncParams is used to carry encoding parameters read from the bitstream at the decoder side while here were going the other direction, i.e., were passing information from the application to the encoder. Secondly, mb_info can't be strictly considered encoding parameters and it's not present in the bitstream at all. It's just a way to give hints to the libx264 encoder on which macroblock we know have not changed since the previous frame and could be coded as P_SKIPs. Libx264 however, may or may not oblige according to its logic, and this specific information is not transmitted in the bitstream nor can be recovered at the decoder.
