查看链接库配置文件

include/etc/ld.so.conf.d/*.conf/usr/local/ssl/lib

发现没有以上的目录在里面加入

/home/ffmpeg-3.2.2/libswscale/home/ffmpeg-3.2.2/libavutil/home/ffmpeg-3.2.2/libavdevice/home/ffmpeg-3.2.2/libswresample/home/ffmpeg-3.2.2/libavformat/home/ffmpeg-3.2.2/libavcodec/home/ffmpeg-3.2.2/libavfilter

在php中执行

$amr=$v['AudioFiles'];$mp3=str_replace(".amr", ".mp3", $amr);if(!file_exists(".".$mp3)){$command = "/usr/local/bin/ffmpeg -i .$amr .$mp3";      system($command,$error);  }

执行的过程中出现126错误，需要修改链接库的用户组
