OK, I found the reason why it could work with the script even we provided an unrecognized palette, we have a fallback method that would use gstreamer to capture the picture when fswebcam fail to do its job.
And when it try to use v4l2src to capture image, it fail with resolution 960x540 and raising this issue.
