791a068c58 build: appease clang warning
Clang complains about these variables being (possibly) unitialized, even
when they are assigned to NULL or proper value inside the macro.

Might as well initialize them to avoid the warning.

e60a94c27d video-frame: Avoid using tile width
The tile width in pixel is not always available. Notably for
8L128 10bit format, the tile is 8x128 bytes, and the pixel
format is fully packed. That means that the tile contains at
least 6 pixels per line, but it also hold some bits of the
pixel from the same line on the previous or next tile.

5980fb76e7 video: Add arbitrary tile dimensions support
In current tile representation, only tiles with power of two
width and height in bytes are supported. This limitation
prevents adding more complex tiles formats.

In this patch, we deprecate tile_ws and tile_hs from GstVideoFormatInfo and
replace if with an array of GstVideoTileInfo. Each plane tiles are then
described with their pixels width/height, line stride and total size.
The helper gst_video_format_info_get_tile_sizes() that depends on the
deprecated API is also being removed. This can simply be removed as it wasn't
in any stable release yet.

This is now moved to the library, so it can be used in multiple
places.

b7ded51382 video: Fix possible overrun when iterating comp[] array
Fix 2 iterations that can overrun the array if the number of component is
equal to the size of the array.

c4255f08f7 video-frame: avoid possible out of bound memory access
Although the components' initialization code would fill in -1 to all
unset components, make the code a bit more defensive and check for an
index bound first.

c9b127dae3 video: Add NV12_16L32S aka Mediatek MM21 support
Unlike other simple tiled formats, the Mediatek HW use different tile size
per-plane. The tile size is scaled according to the subsampling. Effectively,
using the name 16L32S to represent linearly layout tiles of size 16x32 bytes
in the Y plane, and 16x16 in the UV plane. In order to make this specificity
discoverable, a new SUBTILES flags have been added.
