The size of this structure is fixed to 0x11C-bytes. The user process does the LINEAR-mem vaddr->physaddr conversion for the above physaddrs, when modifying the config struct before using [[MVDSTD:SetConfig]].
See [[MVD_Services|here]] regarding "MJPEG". For "MJPEG", the output frame is split into two images via the two output physaddrs.
