Media_player entity_picture few seconds

Configuration Frontend
1

Hi friends. I am trying to show the image of what is being played in a media_player object.
But I would like the image of each media_player to be displayed every two seconds. I wanted to show an image every two seconds and I am doing something wrong. Something is wrong, I don’t know if it’s my code or that the old_time variable is actually being updated as well.
If anyone sees what I did wrong I would appreciate your help.
Thank you

that looks like a custom button card? Assuming it is, you’d need a triggers_update entity that updates every 2 seconds. Date.now() doesn’t update ever.

If I am using a button card. It is what it seemed to me. I’m going to try it, I tell you. Thank you so much

well, that’s definitely not entity_picture and it seems like incomplete yaml.

I understood what trigger update does but I don’t realize how I should work it

Here is this part of the yaml

                      type: custom:button-card
                      entity: media_player.google_mini
                      tap_action:
                        action: none
                      template:
                        - reproducciones
