Video player working, thumbnail not showing (custom post type)

Hi there,

I am having problems with my player, because the thumbnail is not showing.

The reason for this might be the fact that i use custom post types for users to upload videos.

The code i use is:

echo apply_filters(‘the_content’, ‘[fvplayer src="' . $localvideo . '"]‘);

I know that after &localvideo something like thumbnail should be inserted, but i don’t know the exact attribute that belongs to the thumbnail.

Could you help me with this?

best regards, Danny
