av_image_copy() expects an array of four pointers and linesizes according to its declaration; it currently only pointers that are actually in use (depending upon the pixel format), but this might change at any time. It has already happened for the linesizes in d7bc52bf456deba0f32d9fe5c288ec441f1ebef5 and so increasing their array fixes a stack-buffer overread. This fixes a -Wstringop-overflow= and -Wstringop-overread warning from GCC 11.2.
