From ca21cb1e36ccae2ee71d4299d477fa9284c1f551 Mon Sep 17 00:00:00 2001 From: AlexisWilke Date: Mon, 4 Jan 2021 10:11:01 -0800 Subject: [PATCH] avformat/allformats: test pointer to be used Two tests check the opposite pointer before using it. If only one of these is set to a valid pointer, one of these functions will crash, the other will ignore the pointer.
