Generic IP Camera sp32cam Invalid data

Configuration
1

After a painless setup of esp32cam using Arduino IDE the camera web server is all normal and I can start a stream, get a still, etc, etc.

However on trying to add to my 0.91.0 install of HA (on a QNAP Docker) with config set as a Generic IP Camera I added this to my config:

camera:
  - platform: generic
    name: esp32Cam2
    stream_source: http://192.168.1.189:81/stream
    still_image_url: http://192.168.1.189:81/

And on restarting I get the below

av.AVError: [Errno 1094995529] Invalid data found when processing input: 'http://X.X.X.X:81/stream'

The still image and stream never appear.
Has anyone else had a problem with this?
Am I using the right URL’s?

PS: /dev/state shows the entity ID like this:

Entity: camera.esp32cam2

Making some progress here by trying to get another IP Camera connected. Its a very old Techview (Jaycar) IP camera that still works via its web interface.

I have tried in the past to set it up using this component but failed.

At present have the config setup as:

  - platform: generic
    name: techview
    stream_source: rtsp://myUsername:[email protected]:8023/11
    still_image_url: http://X.X.X.X:8023/snapshot?
    username: myUsername
    password: myPassword

However nothing works and the errors say:

ZeroDivisionError: integer division or modulo by zero

I then found that if I forget the stream and just try to get the still image sorted I was able to display the still image AND the stream by using this config below:

As soon as I commented out the stream URL and restart HA I had a live stream working which is a surprise but I’m very happy with that in any case.

I think I will try the same deal with the esp32cam problem above? IE: get the still image working and leave out the stream URL?

I’ll report back as I get onto that.

More progress…

My current Camera config:

camera:
  - platform: generic
    name: esp32Cam2
    still_image_url: http://X.X.X.X/capture?

  - platform: generic
    name: techview
    still_image_url: http://X.X.X.X:8023/snapshot?
    username: myUsername
    password: myPassword

This is currently working for both cameras even though I believe (from what information I have found) the esp32cam is an mjpeg stream.

Can anyone confirm that please?

Cheers!
