Error: av_interleaved_write_frame(): Broken pipe

[gianpyc]

I have a Cloud Key Gen2 Plus with Protect 2.1.2 and I'm trying to get the tsp stream from my Imou camera with the link
unifi-cam-proxy -H 192.168.1.120 -i 192.168.1.122 -c ./client.pem -t 1zFB0YZKNhESzpTfjoPoIKSD22FVHUAA --model 'UVC G4 Pro' rtsp -s 'rtsp://admin:[email protected]:554/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif'

The camera is seen by protect but I can get the snapshot and not the camera streaming that remains with the three dots
In the log I noticed this error:

Can someone help me?
Thanks

It works fine if you use ffmpeg v5. I rebuilt the docker image using ubuntu as a base and it's all working fine.
