How to extract the Content ID of a video uploaded in the resource catalog

Content

Hi,

I need to know the Content ID of a video that has been uploaded in the Catalog Resources.

I tried with the following SQL query, but it seems to extract all the contents in the catalog, except those that are of "video" type.

select    T.NAME, T.DESCRIPTION, CONT.*
 from    WLF_LEARNING_ITEMS_F F
INNER JOIN WLF_LEARNING_ITEMS_F_TL T ON F.LEARNING_ITEM_ID = T.LEARNING_ITEM_ID
INNER JOIN WLF_LI_CONTENT_F CONT
ON F.LEARNING_ITEM_ID = CONT.LEARNING_ITEM_ID
