From 3a0f080ffa5185f45850f15e5e7b8cf997337bf7 Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Fri, 7 Aug 2020 04:58:56 +0200 Subject: [PATCH] avfilter/af_afir: Fix leak of AVFilterChannelLayout in case of error If an error happens between the allocation of an AVFilterChannelLayout and its usage (which involves attaching said object to a more permanent object), the channel layout array leaks. This can simply be fixed by making sure that nothing is between the allocation and the aforementioned usage. Fixes Coverity issue #1250334.
