修改方法：

1、打開/include/FCKeditor/editor/dialog/dede_media.htm 
在

if(playtype=="rm"

|| (playtype=="-" && (rurl.indexOf('.rm')>0 || rurl.indexOf('.rmvb')>0 || rurl.indexOf('.ram')>0)) )

{

revalue = "<embed src='"+ rurl +"' quality='hight' wmode='transparent' type='audio/x-pn-realaudio-plugin' autostart='true' controls='IMAGEWINDOW,ControlPanel,StatusBar' console='Clip1' width='"+ widthdd +"' height='"+ heightdd +"'></embed>/r/n";

}

下面添加以下內容：

//播放代碼flv開始

else if(playtype=="flv" || (playtype=="-" && (rurl.indexOf('.flv')>0 || rurl.indexOf('.swf')>0)) )

{

revalue = "<object id='player' classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' name='player' width='"+ widthdd +"' height='"+ heightdd +"'> /r/n<param name='movie' value='/plus/player.swf'>/r/n<param name='allowfullscreen' value='true'>/r/n<param name='allowscriptaccess' value='always'>/r/n<param name='flashvars' value='file="+ rurl +"'>/r/n</object>";//播放代碼flv開始結束

}

2、上傳player.swf到/plus目錄，搞定

使用時直接在Fckeditor中使用“插入多媒體”功能，輸入flv結尾的視頻地址和高寬度即可。
