Structure

Offset	Size	Description
0x0	0x4	Type, see below.
0x4	0x4	The default for this is 0x0. Must be <=5. When non-zero, the type value at offset 0x0 must be one of the following: 0x00020001, 0x00010001, 0x00010005, 0x00010006, or 0x00010007.
0x8	0x4	The default for this is 0x0. This must be <=1.
0x0C	0x4	Video width. Must be >=width_min and <width_max. This must be aligned: the low <dimensions_alignment>-bits must be clear.
0x10	0x4	Video height. Must be >=height_min and <height_max. This must be aligned: the low <dimensions_alignment>-bits must be clear.
0x14	0x4	Input data physical address, only set for color-conversion. This isn't used when the value at offset 0x4 is 0x1 or 0x5.
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.
0x1C	0x4	Physical data address, only used for color-conversion when the type value is 0x20000. This isn't used when the value at offset 0x4 is 0x1 or 0x5.
0x20	0x4	Physical data address, for color-conversion. This isn't used when the value at offset 0x4 is 0x0 or 0x4.
0x24	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 0x0 or 0x4.
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. 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	See offset 0x40. Video width. Must be >=width_min and <=widthval. Where widthval = <width value from the field at offset 0xC>. The low 3-bits of this value must be clear.
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	Type2, see below. SKATER writes value 0x40002 here. The physaddr at offset 0x68 is only checked when this is value 0x00020001.
0x5C	0x4	Video width. Must be >=16, and must be <somewidth_statefield.
0x60	0x4	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).

See 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.
