Sonoff GK-200MP2-B integration not working on Home-assistant in containers

Hi,
I’m looking for a advice on how to troubleshoot the Sonoff GK-200MP2-B integration with home-assistant.
I have setup the camera with the eWeLink app. This works fine.
Getting it working in Home-assistant, however, is another story

I added the following to my configuration.yml file and restarted home-assistant

ffmpeg:

camera:
  - platform: ffmpeg
    name: westcam1
    input: rtsp://rtsp:[email protected]:554/av_stream/ch0

In home-assistant I can see the entity ID, but when I add a picture-entity card, I get no image
Here is where I’m getting on thin ice and I’m looking for help:
I suspect I am missing ffmpeg on my setup.
My Home-assistant runs in containers on a raspberry pi4 (with an external harddisk)

I tried to understand the documentation at: FFmpeg - Home Assistant and I installed ffmpeg on the Raspberry pi. (should it not be added to one of the containers instead?) but that did not help

pi@raspberrypi:~ $ sudo apt list --installed | grep -i ffmpeg

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

ffmpeg/testing,now 7:4.1.6-1~deb10u1+rpt1 armhf [installed]

Any tips on how to troubleshoot this are greatly appreciated

Hi,
Solved: The issue was that the camera had gotten a different IP. (I need to figure out how to give it a static IP)
Also: the RTSP via the picture entity card has a huge delay
So, I added HACS and added this integration:
https://community.home-assistant.io/t/sonoff-gk-200mp2-b-ip-camera
This works much better
