mpa_to_ros crashes When echoing HIRES

[jacob yaacubov]

Hi, Hope its the correct thread for this question.

I use ROS on my drones system and have launched mpa_to_ros.

my drone has two HIRES cameras (imx 412) apart for tracking
when trying to rosbag record both of them or even echo to both topics the voxl-map-to-ros crashes
i tried to echo different hires topics and even dropped the quality to 1024x768, even 800x600

this doesn't happen with one topic but but only both doesn't matter if its small color or large raw format i am trying to echo
i will appreciate any help on the matter

Thanks

here is the crash output:

Also sometimes it expects on size of data lets say 1444000 bytes but gets 12000000000

@jacob-yaacubov ,

I am not sure why this is happening. However, you maybe able to debug this yourself using gdb and starting the ros node manually:

gdb /opt/ros/melodic/lib/voxl_mpa_to_ros/voxl_mpa_to_ros_node
r __name:=voxl_mpa_to_ros_node __log:=/opt/ros/foxy/log/my_new_ros_log/voxl_mpa_to_ros_node-1.log

(wait for crash)
bt
(this will print stack backtrace, at least will tell you in which function the crash occurred)

Please try..
