How to stream response output?

Hi,

is there any possibility to stream response output?

I would like to stream a video to the browser. But because the video's size is to large I cannot do something like

PHP Code:

$response->setBody($video); 


Currently I am using the following construct that I would like to replace:

PHP Code:

while (...)
{
  $data = fread($handle,$bytesToRead);
  echo $data;
  flush();
  $bytesToRead = ...;
}
