Two cameras stuck my RP - RTSP

Hi
I add two cameras recently and figure out it’s stuck my RP
The streaming working well.
The syntax code require to add next line
still_image_url:

I add it but it’s wrong - not have any path like that. have only RTSP link

What did I need to do?

#  - platform: generic
#    name: test1
#    stream_source: rtsp://admin:[email protected]:8554/Streaming/Channels/101
#    still_image_url: http://192.168.1.120/jpg/image.jpg
#  - platform: generic
#    name: test12
#    stream_source: rtsp://admin:[email protected]:8554/Streaming/Channels/101
#    still_image_url: http://192.168.1.122/jpg/image.jpg

what does that even mean?

I mean my HA on Raspberry pi it’s stop to work
Don’t now why
Not see nothing on the logs

What camera is it?

Arenti m1
Its work great with the configuration I wrote
But after 1-2-5 hours the HA stop work

Now I put the configuration under # comment
And HA back work great and no stuck

I wonder if the configuration it’s bad and stuck the HA?
