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]]. For the above physaddrs that are checked/used, the physaddr must not be 0x0, and the physaddr must be 8-byte aligned(low 3-bits clear).

See [[MVD_Services|here]] regarding "MJPEG". For "MJPEG", the output frame is split into two images via the two output physaddrs.

For *_min/*_max/dimensions_alignment mentioned above: *_min = 16 for color-conversion, 48 for video processing. *_max = 2048 for color-conversion, 4672 for video processing. dimensions_alignment = 4 for color-conversion, 3 for video processing.
