video streaming in gazebo crashes qgroundcontrol

• Ubuntu 20.04
• Latest v4.1.4

QGroundControl exits after launching px4_sitl gazebo_typhoon_h480 which streams video in gazebo.

Error message is:

same problem here

Actual problem might be on gazebo_typhoon_h480. I added camera to iris model, streamed video and QGroundControl works fine.

[dkati]

can i somehow remove camera from typhoon? (kinda offtopic but...needed :P )

[ocpalo]

@dkati There is supposed to be an .sdf file in the path PX4-Autopilot/Tools/sitl_gazebo/models/typhoon_h480/. You can modify that file to remove the camera I guess. If you don't need a camera, why don't you use iris? By default, the iris does not have a camera iirc. You can use iris, use the following command: make px4_sitl gazebo

Removing camera doesn't make qgc NOT crash.

I would like to have hexa copter
