Playing camera stream to Chromecast (or something?)

Trying to get a camera to stream to a chromecast… Have setup, and it works, but takes at least 20-30 seconds to get the stream going. (and the robber has aleady left!!)
Is there any quicker way to do it?
Info: Camera is an ReoLink E1 Outdoor, setup through Frigate>HomeAssistant. Trying to stream to a Google Nest Hub.
YAML:

alias: WhizzPlay
description: ''
triggers:
  - trigger: state
    entity_id: binary_sensor.frontdoor_person
conditions: []
actions:
  - action: camera.play_stream
    metadata: {}
    target:
      entity_id: camera.front_door
    data:
      media_player: media_player.whizz
      format: hls
  - delay:
      hours: 0
      minutes: 5
      seconds: 0
      milliseconds: 0
  - action: media_player.toggle
    metadata: {}
    target:
      device_id: 7d35617.......
    data: {}
mode: single

Thoughts please!! :smiley:
Thanks.

Anyone have any ideas?
