Codeigniter custom routing issue

[eluser]LoganPHP[/eluser]
This is my routes setup code

Code:

$route['general/(:any)'] = "videos/filter/$1/1";
$route['general/(:any)/(:num)'] = "videos/filter/$1/1/$2"; //pagination

Following link works fine.

Code:

www.example.com/general/latest

But below link doesn't work like what i want

Code:

www.example.com/general/latest-trending/5

$route['general/(:any)'] only executes always.

How to solve this issue?
