[Libav-user] Getting pixel value at each x, y position of a given frame

[NDJORE BORIS]

Hello,

Can someone help me to find the value of each pixel on a given frame,
please.
I use frame.data[] and frame.linesize[].
Then I do this :

for(int i = 0; i< height; i++)
{

          for(int j=0 ;j<width; j++)
         {
               xy = height*stride + width
                  int pix_i,j = frame.data[xy][frame.linesize[xy]].
          }
}
where width and height are the dimension of the frame.

I don't know if what I do is right

Regards
