| | 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

| | The default for this is 0x40002. The physaddr at offset 0x68 is only checked when this is value 0x00020001.

| 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.
