Nonai_2D Demo#
Introduction#
Nonai_2D Demo features image overlay functionality and can perform corresponding operations on input files. This functionality has potential application value in scenarios such as image editing and compositing, and can meet the needs of merging and displaying or processing multiple images.
Feature Description#
Nonai_2D performs image overlay operations by reading YUV (I420 format) files. This DEMO is developed based on the kd_mpi_venc series of interfaces, serving as a dedicated demonstration example for the image overlay functionality without other encoding-related features, helping users quickly master the core usage and development logic of image overlay implementation with this series of interfaces.
