GstVideoTileInfo

Description of a tile. This structure allow to describe arbitrary tile dimensions and sizes.

Members

width (guint) –

The width in pixels of a tile. This value can be zero if the number of pixels per line is not an integer value.

height (guint) –
No description available
stride (guint) –

The stride (in bytes) of a tile line. Regardless if the tile have sub-tiles this stride multiplied by the height should be equal to size. This value is used to translate into linear stride when older APIs are being used to expose this format.

size (guint) –

The size in bytes of a tile. This value must be divisible by stride.
