Issues with the Duo Camera Module

Duo

Hi, I’ve just received my second Duo as well as an IOB and camera module. For some reason the camera module test program keeps failing and I don’t know why. This is what it outputs:

When attemping to connect with VLC using vlc rtsp://192.168.1.12:8554/stream0 the output is this on the VLC console:

[00007f2508001650] satip stream error: Failed to play RTSP session
[00007f2508001650] satip stream error: Failed to teardown RTSP session

and this on the camera program console:

connect: 192.168.1.2
disconnect: 192.168.1.2

Can someone give me a few pointers here? I’ve triple checked my camera cable connections and everything is good as far as I can see. I’ve seen this issue pop up a lot on the official camera module forum post but nobody seems to have a fix for it.

Please check the connection of the FPC Ribbon Cable first:

This indicates that communication is established with the camera module. So there is no problem with the FPC ribbon cable connection.

[00007f2508001650] satip stream error: Failed to play RTSP session
[00007f2508001650] satip stream error: Failed to teardown RTSP session

This indicates that this is a VLC issue. In recent years, the VLC packages in the Ubuntu distribution seem to have stopped supporting the rtsp protocol.

If you are using Ubunutu these days, you can use many players that are not VLC.

See this article that I checked.

Thanks a lot! I’ll definitely check it out.

I had a number of problems to get the milkv duo camera to work. The symtom was connection refused when trying to open a stream from my main Linux machine. For me the problem was caused by the file
/etc/protocols
No port was defined for the rtsp protocol.
The solution was to add the following line to the end of the file /etc/protocols on milkv duo:
rtsp 8554 RTSP # Open port for camera streaming

Notice TAB between rtsp 8554 and RTSP.

The camera(s), I bough two, for the milkv duo are surprisingly good quality! After solving the problem with connecting to the rtsp stream from the outside it has worked as a charm. The cameras were bought from Aliexpress.
