Problems with the use of OAK-FFC-4P

Elusive

I have recently purchased the OAK-FFC-4P product but I am having some problems using it and would like to ask for advice. When I am using Depthai-viewer for display, I found that two of the cameras are displaying normally, but the images of the remaining two cameras keep on having coloured grid lines as shown in the picture, I don't know how to proceed to solve this problem.

Hi @Elusive
Could you try with cam_test.py? Also, at what resolution are you running the cameras?

Thanks,

When I use cam_test.py the camera displays fine, I can display 4 colored camera frames, but in dpethai-viewer two of the cameras are displayed with colored stripes. The resolution of the camera used is 1920*1200.

Hi @Elusive
That is very strange. Could you create an issue over at luxonis/depthai-viewer so we can fix it. Also does changing the resolution to something else work? Maybe this could be a mipi issue since two sockets use 2 lane mipi interface while the other (working?) two use 4 lane.

Thanks,

When I set the resolution to 1200p, the display shows coloured stripes, when I lower the resolution to 1280p, the display is normal, and one thing I noticed is that the camera's frame rate is set to 30/60fps, but the picture is still rather jerky and not smooth. Finally, I would like to ask if this software can adjust the exposure of the camera.

I don't think so. Might be easy to add tbf.
