From fadefe356ac82cf5ceab12068b9fea6d1d9c70f0 Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Sun, 29 Aug 2021 11:01:16 +0200 Subject: [PATCH] avformat/flacdec: Also set channels when setting channel_layout This brings the FLAC demuxer in line with all the other demuxers. Furthermore, if it is not done and the FLAC decoder is disabled, the FLAC parser will overwrite the channel layout with the standard channel layout for that number of channels.
