gstvideo.video_affine_transformation_meta

Module for [VideoAffineTransformationMeta] class

class VideoAffineTransformationMeta

Types 1

classVideoAffineTransformationMeta

Extra buffer metadata for performing an affine transformation using a 4x4 matrix. The transformation matrix can be composed with [gstvideo.video_affine_transformation_meta.VideoAffineTransformationMeta.applyMatrix].

The vertices operated on are all in the range 0 to 1, not in Normalized Device Coordinates (-1 to +1). Transforming points in this space are assumed to have an origin at (0.5, 0.5, 0.5) in a left-handed coordinate system with the x-axis moving horizontally (positive values to the right), the y-axis moving vertically (positive values up the screen) and the z-axis perpendicular to the screen (positive values into the screen).
