Description

The problem I meeting is that I use ToOrgOpenCvCoreMat converting frame to mat1. I generate mat2 from mat1. When I try to convert mat2 back to frame, I see all frame Info are missed in my newFrame. I seeOpenCVFrameConverter:178:isEqual comparing the address between frame.images and mat. Is there an elegant way to archieve my goal?

Contributor guide

Research direction
Investigate the OpenCVFrameConverter.toFrame method to understand why metadata is lost. Ensure the Mat is converted back to Frame using the correct Frame dimensions, type, and other properties. Consider using FrameConverter.pushFrame or creating a new Frame with the Mat data.
