This situation happens to the other cameras onboard as well. Here is voxl_cam_ros node output looks like when I was trying to run $ roslaunch voxl_cam_ros tracking.launch: I don't have much experience with compressed image data, but i found this. I think you what you're asking is if there's a way to recover the raw data. In which case you can try and use the republish node, something like this: $ rosrun image_transport republish [in_transport] in:=<in_base_topic> [out_transport] out:=<out_base_topic>A ROS wrapper of the AprilTag 3 visual fiducial detection algorithm. Provides full access to the core AprilTag 3 algorithm's customizations and makes the tag detection image and detected tags' poses available over ROS topics (including tf). ... Subscribe to the "camera/image" base topic. The actual ROS topic subscribed to depends on which transport is used. In the default case, "raw" transport, the topic is in fact "camera/image" with type sensor_msgs/Image. ROS will call the "imageCallback" function whenever a new image arrives. The 2nd argument is the queue size. ROS Write Image, ROS 2 Write Image.
