CM3 both cameras recognized but stereo not working

Question

I recently started to work with the CM3. When I start raspbian, I can check that both cameras are detected and supported. In addition, I can acquire an image/a video from each separately easily but I can not acquire a stereo image with the 3d flag of raspistill/raspivid. Only one camera is displayed. If I force one or the other with the C's flag, I only see one of the images but never the two combined...

Edit: I am using the pi noir V2. I realized that my problem came from a misunderstanding/misuse of the command raspivid. I am able to record in stereo (if I read the recorded file in vlc, I see both cameras), it is just that the preview shows only one camera, never the "stereo" view. Is it normal?

What am I missing? Thanks in advance!

Answer 1

I hit the same thing today when setting up a CM with the StereoPi hardware. Actually it did work - it just did not display the two cameras while recording. Output to a file and view the file, you'll see both images. For still pictures, try something like raspistill -n -t 1 -3d sbs -cs 1 -vf -hf -w 5184 -h 1944 -o image.jpg;sudo fbi --autozoom --noverbose --vt 1 image.jpg after installing fbi. Use -vt 2 if you're using the GUI rather than the console.
