Image Processing ALPR with Ring Floodlight

Configuration
1

Can anyone one help me with a query

Is ALPR / Image processing supported with the Ring Floodlight

This is what I have and I feel like this it should work

image_processing:
 - platform: openalpr_local
   region: eu
   source:
    - entity_id: camera.front_floodlight

Initially had an error

Fixed FFMPEG then got

I’m getting a video though on the camera - but its not working.

How does the image get pulled from the camera?

Further fun and testing…

A camera cant have a space in its name - my ring camera had a space in the name - so I removed it and now I get a new error

2018-09-29 09:52:19 ERROR (MainThread) [homeassistant.components.image_processing] Error on receive image from entity: Unable to get image

UPDATE: After updating to 0.79 I removed the single quotes from the ffmpeg command and this error went away. Still no number plate though

Never got it working locally with Ubuntu 18.04 - but when using the ALPR Cloud Service it works fine.

The cloud service gives other benefits like make and model of car - HA only makes use of the car count with registration
