Video Plugin Crashes Gzserver (Gazebo9)

[arixrobotics]

Hello all,

It seems that the video plugin libgazebo_ros_video.so is crashing gzserver everytime I load it in ROS Kinetic + Gazebo 9.

This is the code snippet:

<gazebo reference="screen">
<visual>
 <plugin name="screen_video_controller" filename="libgazebo_ros_video.so">
   <height>600</height>
   <width>1024</width>
   <topicName>/robot/head_display</topicName>
   <robotNamespace>/robot</robotNamespace>
 </plugin>
</visual>
</gazebo>

If I try to load this model, I'll get:

...
[ INFO] [1533119655.853751756]: GazeboRosVideo (gzclient, ns = /robot) has started
Segmentation fault (core dumped)
[gazebo_gui-3] process has died [pid 12932, exit code 139, cmd /opt/ros/kinetic/lib/gazebo_ros/gzclient __name:=gazebo_gui __log:=/home/arif/.ros/log/6157ef48-9576-11e8-90e1-6c71d97cbaff/gazebo_gui-3.log].
log file: /home/arif/.ros/log/6157ef48-9576-11e8-90e1-6c71d97cbaff/gazebo_gui-3*.log

But if I comment out that part, it loads ok (without that video display, of course).

I've seen this issue, but it seems like a different case #354

Can anyone help?

Thanks for the report. I'm curious if this is related to #646. Are you able to test this with gazebo7 + Kinetic?

I've tried on Kinetic + Gazebo 7, it works fine. I'll try to check on the cv2/3 clash and see if that's the issue.

Building gazebo_ros_video and cv_bridge from source works fine.

Hi, can you provide me a model which use libgazebo_ros_video.so as plugins? I tried very hard but failed to build a model which can display videos from rostopic. Please give me a demo model, thanks a lot!!!
