Passing parameter to controller method fails

[eluser]Kimse[/eluser]
Hi


I have an url like this

http://exmaple.com/video/1

and route like this:

Code:

$route['video/:num'] = 'players/video/$1';

and my controller method:

Code:

public function video($video_id) {        
        var_dump($video_id);
...

this is the var_dump output:

string(2) "$1"

and I expected $video_id to contain 1
