脚本宝典收集整理的这篇文章主要介绍了ffmpeg-php创建视频缩略图，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
然后我将ffmpeg-PHP复制到我的服务器上并运行测试文件
输出： –

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!'; ?>
//thumb path should be added in the below code
//test for thumb
$dir_img='uploads/';

$file_thumb=create_movie_thumb($dir_img.$mediapath,$mediapath,$mediaid);
$name_file=explode(".",$mediapath);

function create_movie_thumb($src_file,$mediaid)
{

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

$dest_file = $CONfig['fullpath'].$imgname;

} else {

}
$output = array();

} else {

$cmd = "{$CONfig['ffmpeg_path']}ffmpeg -i $src_file -an -ss 00:00:05 -r 1 -vframes 1 -y $ff_dest_file";
exec ($cmd,$retval);
}
if ($retval) {
$ERROR = "Error executing FFmpeg - Return value: $retval";
if ($CONfig['debug_mode']) {
// Re-execute the command with the backtick operator in order to get all outputs
// will not work if safe mode is enabled
$output = `$cmd 2>&1`;
$ERROR .= "<br /><br /><div align=\"left\">Cmd line : <br /><span style=\"font-Size:120%\">" . nl2br(htMLspecialchars($cmd)) . "</span></div>";
$ERROR .= "<br /><br /><div align=\"left\">The ffmpeg program said:<br /><span style=\"font-size:120%\">";
$ERROR .= nl2br(htmlspecialchars($output));
$ERROR .= "</span></div>";
}
@unlink($dest_file);
return false;
}
$return = $dest_file;
//@chmod($return,octdec($CONfig['default_file_mode'])); //silence the output in case chmod is disabled
return $return;
}
享受编码
