template <, >SelfType & set_vertically_flipped (typename SelfType::ValueType val)If true, the captured contents are flipped vertically.
This bit is documented for VDIN0 but not documented for VDIN1 in any
Amlogic datasheets. Both "Display Write Back App-Note" and experiments on
Khadas VIM3 (A311D) show that both video input modules have this bit
available.

template <, >SelfType & set_top_line_inclusive (typename SelfType::ValueType val)The top row (inclusive) to write on the write image buffer, in lines.
Must be less than or equal to `bottom_inclusive`.
The Amlogic datasheets specify that this field uses bits 28-16 for VDIN0
bits 27-16 for VDIN1. However, both the "Display Write Back App-Note"
and experiments on Khadas VIM3 (A311D) confirm that it actually uses
bits 28-16 for both VDINs.
It's preferred to use the `SetVerticalRange()` helper method.

VideoInputWriteRangeVertical & SetVerticalRange (int top_line_inclusive, int bottom_line_inclusive)Set the vertical range of the write image buffer to `[top_line_inclusive,
bottom_line_inclusive]`.
`top_line_inclusive` must be less than or equal to `bottom_line_inclusive`.
Both `top_line_inclusive` and `bottom_line_inclusive` must be non-negative
and less than 2^13 (8192).
