core\function\function_core.php中
/*
检查权限函数
$ret:Pdecode函数返回的数组
$action:需要判断的权限
*/
function Cdecode($ret = array(), $action = 'read')
{
global $_G;
$powerarr = \perm::getPowerArr();

if (isset($ret['perm'])) {
    $perm = intval($ret['perm']);

上传视频时$perm的值一直是0导致if ($perm & intval($powerarr[$a])) 位运算时总是失败
