视频文件速度补丁

上面的修改只能在首页有效,在制作缩图时仍然比较慢,所以直接重新包装getimagesize函数.

#!/bin/sh
tmp=/tmp/searchreplace
sed 's/getimagesize/wz_getimagesize/g' $1 >$tmp
mv $tmp $1

将所有getimagesize替换为wz_getimagesize

find photo/ -name *.php -exec grep -H getimagesize {} \;

需要替换的文件有:

./member.php
./admin/resizer.php
./admin/admin_functions.php
./admin/thumbnailer.php
./includes/functions.php
./includes/image_utils.php
./includes/upload.php
./includes/captcha_utils.php

在./includes/functions.php中添加

function wz_getimagesize($src,&$info)
{       
 return (filesize($src)<5000000 && !wz_is_mov($src))? getimagesize($src,$info):0;
}

视频文件缩略图补丁

对电影格式提供生成所略图支持,上传后自动生成.jpg的所略图,支持ftp上传后,批量生成.参考Web¹.
在inclues/functions.php里添加:

function wz_is_mov($src)
{
 return in_array(get_file_extension($src), array("mpg", "mpeg", "avi","asf","wmv","flv","swf","mov"))? 1:0;
}
function Generate_VideoThumb($src, $dest) {
      global $convert_options;
     // $command = "/usr/bin/mplayer \"".$src."\" -ss 00:00:05 -nosound -vo jpeg:smooth=100 -vop scale=200:150 -frames 1";
      $command = "/usr/bin/mplayer \"".$src."\" -nosound -vo jpeg:smooth=100 -vop scale=200:150 -frames 1";
    system($command);
    rename("00000001.jpg",$dest);
    return (file_exists($dest)) ? 1 : 0;
}

在“设置界面“也要添加上述后缀,否则“搜索新文件时查找不到.
-ss 00:00:05对某些视频文件不能生成.jpg,设置为00:00:00正常.

修改:includes/image_utils.php

function create_thumbnail($src, $dest, $quality, $dimension, $resize_type) {
  global $convert_options;
  if (file_exists($dest)) {
    @unlink($dest);
  }
  $image_info = (defined("IN_CP")) ? wz_getimagesize($src) : @wz_getimagesize($src);
  if (!$image_info) {
          //**modified from here
          //return false;
        if(wz_is_mov($src) && Generate_VideoThumb($src, $dest)) {
                 echo "[".$src."|".$dest."]";
        return true;
         }
         echo "[".$src."|".$dest."]";
         //**modified to here
     return false;
  }
  $width_height = get_width_height($dimension, $image_info[0], $image_info[1], $resize_type);
  $resize_handle = "resize_image_".$convert_options['convert_tool'];
  if ($resize_handle($src, $dest, $quality, $width_height['width'], $width_height['height'], $image_info)) {
    @chmod($dest, CHMOD_FILES);
    return true;
  }
  else {
    return false;
  }
}

修改member.php

    // Uplad thumb file
    $new_thumb_name = "";
    if (!empty($HTTP_POST_FILES['thumb_file']['tmp_name']) && $HTTP_POST_FILES['thumb_file']['tmp_name'] != "none" && !$uploaderror) {

        $msg .= (($msg != "") ? "<br />" : "")."<b>".$lang['thumb_upload_error'].": ".$new_thumb_name."</b><br />".$site_upload->get_upload_errors();
        @unlink(MEDIA_TEMP_PATH."/".$new_name);
        $uploaderror = 1;
      }
    }
    elseif (check_remote_thumb($remote_thumb_file)) {
      $new_thumb_name = $remote_thumb_file;
    }
    elseif ($config['auto_thumbnail'] == 1 && !empty($HTTP_POST_FILES['media_file']['tmp_name']) && $HTTP_POST_FILES['media_file']['tmp_name'] != "none" && !$uploaderror) {

        $dest = THUMB_PATH."/".$cat_id."/".$new_name;
      }
      else {

        $dest = THUMB_TEMP_PATH."/".$new_name;
      }
      $do_create = 0;

        if ($image_info[2] == 1 || $image_info[2] == 2 || $image_info[2] == 3) {
          $do_create = 1;
        }
      }
      if ($do_create) {
        require(ROOT_PATH.'includes/image_utils.php');
        $convert_options = init_convert_options();
        if (!$convert_options['convert_error']) {
          $dimension = (intval($config['auto_thumbnail_dimension'])) ? intval($config['auto_thumbnail_dimension']) : 100;
          $resize_type = (intval($config['auto_thumbnail_resize_type'])) ? intval($config['auto_thumbnail_resize_type']) : 1;
          $quality = (intval($config['auto_thumbnail_quality']) && intval($config['auto_thumbnail_quality']) <= 100) ? intval($config['auto_thumbnail_quality']) : 100;
          if (create_thumbnail($src, $dest, $quality, $dimension, $resize_type)) {
            $new_thumb_name = $new_name;
          }
        }
      }
      //**********add from here
      else if (wz_is_mov($new_name)) {
              if (Generate_VideoThumb($src, $dest.".jpg"))
              $new_thumb_name = $new_name.".jpg";
         }
      //**********add to here

修改admin/thumbnailer.php

        @set_time_limit(90);
        //****************added from here
        $wz_dst=$image_cache[$key]['image_media_file'];
        if (wz_is_mov(MEDIA_PATH."/".$image_cache[$key]['cat_id']."/".$image_cache[$key]['image_media_file'])) $wz_dst=$wz_dst.".jpg";

                $sql = "UPDATE ".IMAGES_TABLE."
                  SET image_thumb_file = '".addslashes($wz_dst)."'
                  WHERE image_id = $key";
        //******************************************
          $site_db->query($sql);
          echo "<br />&nbsp;&nbsp;&nbsp;<b>".$lang['creating_thumbnail_success']."</b><p>";
        }
        else {
