Hello.
I have buffer with yuy2 data I need to save it on local drive, one frame only.
Do I need to convert it first to rgb or some thing ?

Hi Everyone ,
I am always confused with basics of data types .
Why does

Hey :D so I'm trying to create a ternary tree from an array of strings, simple as that, but the program won't run. Now I'd like to know what am I doing wrong here maybe not in the way of thinking?
#include<stdio.h>
#include<string.h>
#define P 100
#define N 3
typedef struct{
