From d1f7a44e89fa90748a71c7d714c53036a2a44800 Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Mon, 6 Dec 2021 12:19:46 +0100 Subject: [PATCH] avcodec/libkvazaar: Increase array size 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.
