From 84b1919124884232e0fa30b30458470db27c73fc Mon Sep 17 00:00:00 2001 From: James Cowgill Date: Sat, 18 Aug 2018 12:56:38 +0200 Subject: [PATCH] Use AV_INPUT_BUFFER_PADDING_SIZE to determine padding size Hardcoding the value for FF_INPUT_BUFFER_PADDING_SIZE is not safe because upstream FFmpeg might change it (as they did in FFmpeg 4.0). Instead, use FFmpeg's AV_INPUT_BUFFER_PADDING_SIZE if available and only hardcode a value if FFmpeg is disabled (in which case the value doesn't particularly matter anyway). For compatibility with older FFmpeg versions, define AV_INPUT_BUFFER_PADDING_SIZE if hasn't been defined yet.
