Image analysis has a misalignment issue

There is an issue with the output of the collected images on the Jetson Orin NX. Is this issue related to image decoding?

Hello @shenchengzha,

That seems like a timing or register configuration issue.

Just a couple of questions.

  1. What sensor are you using?
  2. Where did you get the driver? Are you developing it yourself?
  3. On the embedded_metadata_height line there is a syntax error with the "4; I assume that was introduced when copying and pasting the required information for this pots. Please confirm.
  4. Do you have access to the sensor documentation ?

regards,
Andrew

The image capture by vl42-ctl?
Try set the preferred_stride=5120 by below command.

v4l2-ctl -c preferred_stride=5120
