[Motion-user] Stop decaying to only compare one frame

[aaron b. <as_...@ya...>]

Hi Kenneth,

Remember the issue I have with tracking motion not working because of the decaying image?  You've
fixed that for me in the past by only comparing a frame to the previous one, by editing in
motion.c:

>                  for (i=cnt->imgs.size-1; i>=0; i--) {
>                          cnt->imgs.ref[i]=(cnt->imgs.ref[i]+newimg[i])/2;
>                  }
> 
> and replace it with
>                  memcpy(cnt->imgs.ref, newimg, cnt->imgs.size);
> 

However, the current version of motion.c now looks like:

			for (i=cnt->imgs.size-1; i>=0; i--) {
				*imgs_ref_ptr = (*imgs_ref_ptr + *newimg_ptr)/2;
				imgs_ref_ptr++;
				newimg_ptr++;
			}

and if I replace that whole chunk with the piece you gave me above, then motion detection fails. 
It compiles, but detects motion on every frame.  So . . . something broke somewhere and I don't
know how to fix it.

Is there any chance you could tell me a fix to disable the decaying feature in the latest version?

Thank you!

Aaron
