Hi,

Most of the time, what you get from GigEVision or USB3Vision are raw data. That is what you will find in the ArvBuffer data member.

Here is the simplest example on how to retrieve a buffer from a camera:

github.com

AravisProject/aravis-c-examples/blob/main/01-single-acquisition.c

/* SPDX-License-Identifier:Unlicense */

/* Aravis header */

#include <arv.h>

/* Standard headers */

#include <stdlib.h>
#include <stdio.h>

/*
 * Connect to the first available camera, then acquire a single buffer.
 */

int
main (int argc, char **argv)
{
	ArvCamera *camera;
	ArvBuffer *buffer;
