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 here regarding "MJPEG". For "MJPEG", the output frame is split into two images via the two output physaddrs.
Description
For this command, MVD module DMAs 0x11C-bytes from a MVD state structure to the above output buffer.
