php 使用php-ffmpeg转换一个flv的文件为mp4的格式时，报了一个错，帮忙看看什么问题？

Question

我的代码：

$ffmpeg = FFMpeg\FFMpeg::create();
$video = $ffmpeg->open($save_path . 'www.flv');
$format = new FFMpeg\Format\Video\X264();
$video->save($format, $save_path . 'test.mp4');

执行的时候报
错误：Encoding failed；/home/ljg/workspace/tools.51safety/vendor/php-ffmpeg/php-ffmpeg/src/FFMpeg/Media/AbstractVideo.php 第106行；追溯：

然后我到106行debug出日志，发现他执行的命令是下面的：

'/usr/local/bin/ffmpeg' '-y' '-i' '/home/ljg/workspace/tools.51safety/upload/anquanwuyouwang/professional/resource/learning/www.flv' '-vcodec' 'libx264' '-acodec' 'libfaac' '-b:v' '1000k' '-refs' '6' '-coder' '1' '-sc_threshold' '40' '-flags' '+loop' '-me_range' '16' '-subq' '7' '-i_qfactor' '0.71' '-qcomp' '0.6' '-qdiff' '4' '-trellis' '1' '-b:a' '128k' '-pass' '1' '-passlogfile' '/tmp/ffmpeg-passes5be4fc1ec9c1auy3kq/pass-5be4fc1ec9cae' '/home/ljg/workspace/tools.51safety/upload/anquanwuyouwang/professional/resource/learning/test.mp4'

然后我单独把这行命令放在ubuntu14.04的cli下面执行，执行报错信息如下

就是报了一个segmentation fault (core dumped)，是什么意思啊？我环境没有配置好么？
