av_image_copy() expects an array of four pointers according to its declaration; although it currently only touches pointers that are actually in use (depending upon the pixel format) this might change at any time (as has already happened for the linesizes in d7bc52bf456deba0f32d9fe5c288ec441f1ebef5). This fixes a -Wstringop-overflow= warning with GCC 11.2. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com> (cherry picked from commit b09ea67b40e342f5e4183e9ebc0c14801ecd218c)
