影片转码：

ffmpeg -y -i oceans.mp4 -vcodec copy -acodec copy -vbsf h264_mp4toannexb out.ts

function getVideoTime($time){

 $hour = floor($time/3600);

 $time = ($time-$hour*3600);

 $min = floor($time/60);

 $sec = $time - $min*60;

 return sprintf('%2d:%2d:%2d',$hour,$min,$sec);

}

影片分段：

  1.获取影片的时长： ffmpeg -i youku.mp4 2>&1 | grep 'Duration' | cut -d ' ' -f 4 | sed s/,//               00:00:50.33

  $time = explode(':',$timeLength);list($hour,$min,$sec) = $time;

  $totalSec = $hour*3600+$min*60+$sec;

  $sliceTime = 20min;

  $hours = $sliceTime%60;

  $sliceStep =  ceil($totalSec/($sliceTime*60));

  for($i=0;$i<$sliceStep;$i++){

    $time = getVideoTime($i*$sliceTime*60);

    

  }

  2.影片切段：          ffmpeg -ss 00:00:00 -t 01:30:00 -i input.mp4 -acodec copy -vcodec copy output1.mp4
