    Currently, I am using the voxl_mpa_to_ros2 repository. Do you have any idea what causes the following error

    ERROR: invalid metadata, magic number=0, expected 1448040524
    most likely client fell behind and pipe overflowed

    This only happens when I try streaming the depth_image through the piep> There is no problem with lowbandwith data like imu_app/qvio odometry. Do you know what the root cause is for this or if there is a way to solve this in ROS2?

    Thanks,

    Jeff

      @Jeffrey-Mao , does this happen occasionally (how often) or very frequently (every frame?)

        This happens if we leave the pipe on while streaming depth_images from stereo_disparity for a minute or two. After which it happens very frequently.

          @Jeffrey-Mao , depth_image is just a regular image, correct (not a 3D point cloud)? What is publishing this image?

            @Alex-Kushleyev Sorry for the confusion I mean Disparity Image.

            On further examination, I think this is a network problem. When streaming high bandwith objects like Disparity images or images in general across wifi. I think effectively managing the bandwidth can alleviate this problem.
