RTSP stream connection issues

Camera model is LTS CMIP8942NW(rebranded hikvision)

Running octoprint 1.4 on octopi 0.16.0.0

I am able to connect to the cameras RTSP stream in VLC using

rtsp://<username>:<password>@<IP>:<PORT>/Streaming/channels/102
in my case
rtsp://admin:password@10.12.10.220:554/Streaming/channels/102

but unable to connect after adding the same credentials in octoprint. I did not see anything related in octoprint.log

I have tried both the h264 and MJPEG stream and get the same result

I have also tried both 16:9 and 4:3

Any tips?

Out of the box, only MJPEG is supported, and only over http, not over rtsp. Does the camera support streaming mjpeg over http?
