Dlna_dmr component

Dear,
I am unable to set dlna_dmr on my hass.io installed on raspbian strech.
my config

always shows error:
platform dlna_dmr not yet ready

please guide me .
thanks in adv

I also have issues trying to set up dlna media players also on Raspbian - Buster in my case.
My aim is to stream local media (music, photos, videos) to a 2014 Samsung TV and to Google Home ( music only obviously).
My config is

discovery:
#   ignore:
#     - samsung_tv
  enable:
    - dlna_dmr

media_player:
  - platform: dlna_dmr
    url: http://192.168.1.120:7676/description.xml
    name: Samsung_DLNA
  - platform: dlna_dmr
    url: http://192.168.1.100
    name: Google_DLNA

and my error log with debug looks like this

There has been some great work done on the dlna_dmr component. I would love to make use of it on my system but need some help with these errors.
