本文实例讲述了PHP实现将视频转成MP4并获取视频预览图的方法。分享给大家供大家参考。具体实现方法如下:

复制代码 代码如下:<?phpflv_convert_get_thumb("input.avi", "output.jpg", "output.ogm");// code provided and updated by steve of phpsnaps ! thanks// accepts:// 1: the input video file// 2: path to thumb jpg// 3: path to transcoded mpeg?function flv_convert_get_thumb($in, $out_thumb, $out_vid){  // get thumbnail  $cmd = "ffmpeg -v 0 -y -i ".$in." -vframes 1 -ss 5 -vcodec mjpeg -f rawvideo -s 286x160 -aspect 16:9 ".$out_thumb;  $res = shell_exec($cmd);  // $res is the output of the command  // transcode video  $cmd = "mencoder ".$in." -o ".$out_vid." -af volume=10 -aspect 16:9 -of avi -noodml -ovc x264 -x264encopts bitrate=500:level_idc=41:bframes=3:frameref=2: nopsnr: nossim: pass=1: threads=auto -oac mp3lame";  $res = shell_exec($cmd);}?>
