laravel - Php FFMPEG request timout -

i using laravel 4.2.

i working on project of uploading video. uploaded video should played in devices using php-ffmpeg package git-hub.

the requirement transcoding should done in background. using wamp 2.5.

what doing is, after upload firing asynchronous ajax request transcode video , after successful completion should insert record database containing video name, path etc.

the problem if upload large size video, facing error maximum execution time of 120 seconds exceeded.

i know possible solution setting max_timelimit in php.ini don't think feasible solution because if there larger video, same error occurred again.

is there technique can bypass transcoding process in background?

my code below :

try{             $video_id = input::get('video_id');             $video_path = input::get('video_path');              $path = '/video/'.date('y').'/'.date('m');             $path .= '/';             $explode_filename  = explode("/",$video_path);             $save_filename = $explode_filename[sizeof($explode_filename)-1];              $ffmpeg = ffmpeg\ffmpeg::create(array('timeout'=>0));             $video = $ffmpeg->open($video_path);              $format = new customvideo();             $format->setkilobitrate(1000)                     ->setaudiochannels(2)                     ->setaudiokilobitrate(256);              $video->save($format, public_path().$path.$save_filename);              //saving video              video::where('id', '=', $video_id)->update(array('is_transcoded' => 1,'video_url'=>url($path.$save_filename)));         }         catch (exception $ex){            return response::json (["message"=>$ex->getmessage(), "code"=>$ex->getcode(), "trace"=>$ex->gettrace()]);         }
