 +
|-
 +
| 0x18
 +
| 0x4
 +
| Physical data address, only used for color-conversion when the type value has bitmask 0x20000 set. This isn't used when the value at offset 0x4 is 0x1 or 0x5.

|-
 +
| 0x40
 +
| 0x4
 +
| When non-zero this enables usage of the 4 words starting at offset 0x44. Normally this is set to 0x0 for color-conversion, and 0x1 for video processing.
 +
|-
 +
| 0x44
 +
| 0x4
 +
| See offset 0x40. The default for this is 0x0. Must be <=widthval. Where widthval = <width value from the field at offset 0xC>. The low 4-bits of this value must be clear.
 +
|-
 +
| 0x48
 +
| 0x4
 +
| See offset 0x40. The default for this is 0x0. Must be <=heightval. Where heightval = <height value from the field at offset 0x10>. The low 4-bits of this value must be clear.
 +
|-
 +
| 0x4C
 +
| 0x4
 +
| See offset 0x40. Output video height. Must be >=16 and <=heightval. Where heightval = <height value from the field at offset 0x10>. The low 3-bits of this value must be clear.

|-
 +
| 0x50
 +
| 0x4
 +

 +
|-
 +
| 0x54
 +
| 0x4
 +
| The default for this is 0x0. Must be <=5. For video processing, and when this value is non-zero, the type value at offset 0x0 must not be any of the following: 0x00010004, 0x00010001, 0x0x00100001, or 0x00200001. For video processing, the type value at offset 0x0 must not be 0x80000 when this value at offset 0x54 is non-zero.
 +
|-
 +
| 0x58
 +
| 0x4
 +
| Output format type, see below. SKATER writes value 0x40002 here. The physaddr at offset 0x68 is only checked when this is value 0x00020001.
 +
|-
 +
| 0x5C
 +
| 0x4
 +
| Output video width. Must be >=16, and must be <somewidth_statefield.
 +
|-
 +
| 0x60
 +
| 0x4
 +
| Output video height. Must be >=16, and must be <someheight_statefield.

| 0x64
 +
| 0x4
 +
| Output data physical address.

 +
| 0x68
 +
| 0x4
 +
| Output data physical address, only set for color-conversion.

 +
 +
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).
 +
 +
For color-conversion, 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.
 +
 +
The configuration doesn't seem to change at all while SKATER is running video processing(each [[MVDSTD:SetConfig]] input config appears to the same).
