| 0x64 | 0x4 | Output data physical address. |
| 0x68 | 0x4 | Output data physical address, only set for "MJPEG". |
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.
