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!
