VisionEngine Library

Hello everyone: based on a library that is on GitHub for free use and in my free time I decided to implement the use of a simple WEBCAM with the other project called Zbar.

Links:
https://github.com/sipsorcery/mediafoun ... pleGrabber
https://linuxtv.org/downloads/zbar/bina ... 64-VfW.zip

despues de muchos dias luchando con Gemini porque ya tenia el SampleGrabber integrado y exportado todas sus funciones
seguia sin tener la imagen dentro del formulario HMG.

Leyendo foros encuentro que MF (Media Fundacion) no genera Ventana de video,
por eso no tenia video.. Basandome en foros y la ayuda de ChatGPT resumi SampleGrabber.cpp, SampleGrabber.h en VisionEngine.cpp
una libreria que comparto con uds para integarlo en cualquier proyecto.

After struggling for days because I already had the SampleGrabber integrated and all its functions exported, I still couldn't get the image to appear inside the HMG form.
While researching various forums, I discovered that Media Foundation (MF) does not automatically generate a video window, which is why the video wasn't rendering.

Based on forum discussions and some AI assistance, I refactored and consolidated SampleGrabber.cpp and SampleGrabber.h into a single library called VisionEngine.cpp. I am sharing this library with the community so it can be easily integrated into any project.

ya sabes usar el IDE asi que abres el proyecto y compilas
You know the IDE , so just open the project and run the build

Hola a Todos !!!
Mientras tengo tiempo como Piercer ( mi actual trabajo ) deje la electronica y programacion (despues de 30 años de actividad) volvi con ese proyecto que surgio de una pregunta en el foro...
cambie el rumbo de la app que escanea un codebar (con ayuda de Zbar "Todos") pero en la logica solo EAN13 y QR, veia que funcionaba pero era muy lineal y contenia errores que IA corrigio.. asi que como siempre me gusto leer sobre threads y pedirle a la IA ejemplos de usos para ver su funcionamiento lleve a VisionEngine a VisionEngineMT ...esto es Interfaz de usuario despegado del motor (MF + Zbar y proximamente HBZEBRA!!!!)
se los dejo para su uso !!!!
los leo y gracias por compartir sus experiencias en cada post dentro del Foro... lastima que en el camino van quedando los viejos Clipperos

Hello everyone!
While I have some free time as a Piercer (my current job), I've put electronics and programming aside (after 30 years in the field). I've returned to a project that originated from a question on the forum... I changed the direction of the app that scans barcodes (using Zbar "Todos"), but in the logic, it only handles EAN13 and QR codes. I saw that it worked, but it was very linear and contained errors that AI corrected. So, as I always enjoy reading threads and asking AI for usage examples to see how it works, I brought VisionEngine to VisionEngineMT... This is a user interface detached from the engine (MF + Zbar and soon HBZEBRA!!!!)
I'm sharing it with you for your use!
I read your posts and thank you for sharing your experiences in each one on the forum... It's a shame that the old Clippers are being left behind.

Vision.log – Technical Reference
Overview

The log is designed for debugging, system monitoring, and post-run analysis of the Vision Engine pipeline.
