PHP error when processing big videos

[AlexTr]

(PHP Fatal error: Allowed memory size 4294967296 bytes exhausted (attempted to allocate 2548056064 bytes) in /.../inc/utils. inc.php on line 1054)

the relevant line from utils.inc.php:

$sResult = curl_exec($rConnect);

it's better to remake downloading routine to download by chunks to avoid high memory usage, to write directly to file with curl use CURLOPT_FILE option.
