                'ffprobe.binaries' => "ffprobe 可执行文件地址"

    $video->save(new FFMpeg\Format\Video\X264(), $path);
  //截取视频第一针作为封面图片
   $video->frame(\FFMpeg\Coordinate\TimeCode::fromSeconds(1))->save($poster);
  //宽
  $width = $video->getStreams()->videos()->first()->get("width");
  //高
  $height = $video->getStreams()->videos()->first()->get("height");
  //视频时长
  $duration =$video->getStreams()->videos()->first()->get("duration");
