我正在尝试使用此脚本使用ffmpeg创建视频缩略图.起初我使用了phpinfo();我发现ffmpeg安装在我的服务器上.
然后我将ffmpeg-php复制到我的服务器上并运行测试文件 我知道很多功能正在我的服务器上运行 我有这样的输出 输出： – Functions available in /usr/lib/php/extensions/no-debug-non-zts-20060613/ffmpeg.so extension: Methods available in class ffmpeg_movie: __construct getduration getframecount getframerate getfilename getcomment gettitle getauthor getartist getcopyright getalbum getgenre getyear gettracknumber getframewidth getframeheight getframenumber getpixelformat getbitrate hasaudio hasvideo getnextkeyframe getframe getvideocodec getaudiocodec getvideostreamid getaudiostreamid getaudiochannels getaudiosamplerate getaudiobitrate getvideobitrate getpixelaspectratio getpixelaspectratio getvideobitrate getaudiobitrate getaudiosamplerate getaudiochannels getaudiostreamid getvideostreamid getaudiocodec getvideocodec getframe getnextkeyframe hasvideo hasaudio getbitrate getpixelformat getframenumber getframeheight getframewidth gettracknumber getyear getgenre getalbum getcopyright getartist getauthor gettitle getcomment getfilename getframerate getframecount getduration __construct 我编写了这段代码并尝试了任何可能的路径来分配$ffmpeg; <?php
$thumb_stdout;
$retval=0;
$ffmpeg = '/home/lib/ffmpeg';
// change "demo.mpg" to your mpg file name!
$video = dirname(__FILE__) . 'demo.mpg';
// change "demo.jpg" to whichever name you like or don't
// for this example,the name of the output jpg file does not matter
$image = dirname(__FILE__) . 'demo.jpg';
$second = 1;
$cmd = "$ffmpeg -i $video 2>&1";
if (preg_match('/Duration: ((d+):(d+):(d+))/s','$cmd',$time)) {
$total = ($time[2] * 3600) + ($time[3] * 60) + $time[4];
$second = rand(1,($total - 1));
}
//$cmd = "$ffmpeg -i $video -deinterlace -an -ss $second -t 00:00:01 -r 1 -y -vcodec mjpeg -f mjpeg $image 2>&1";
$cmd = "$ffmpeg -i $video -r 1 -ss 00:00:05 -t 00:00:01 -s 250x250 -f image2 $image";
echo $cmd;
exec($cmd);
//$return = '$cmd';
echo '<br>done!';
?>
最后我得到了代码感谢Anubhaw.Your链接帮助了很多.试试这段代码.
//thumb path should be added in the below code
//test for thumb
$dir_img='uploads/';
$mediapath='123.jpg';
$file_thumb=create_movie_thumb($dir_img.$mediapath,$mediapath,$mediaid);
$name_file=explode(".",$mediapath);

{

$dir_img='uploads/';
$CONFIG['fullpath'] = $dir_img."thumbs/";
$src_file = $src_file;

$dest_file = $CONFIG['fullpath'].$imgname;
if (preg_match("#[A-Z]:|\#Ai",__FILE__)) {

}
$output = array();

}
if ($retval) {
$ERROR = "Error executing FFmpeg - Return value: $retval";
if ($CONFIG['debug_mode']) {

$output = `$cmd 2>&1`;
$ERROR .= "<br /><br /><div align="left">Cmd line : <br /><span style="font-size:120%">" . nl2br(htmlspecialchars($cmd)) . "</span></div>";

}

}

return $return;
}
