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. Source: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=901735
