Issue when trying to open both RGB and Event cameras #49

Closed samchopra2003 closed 3 months ago

samchopra2003 commented 3 months ago

For the RGB camera, I am using the Flir Blackfly S with this driver: https://github.com/ros-drivers/flir_camera_driver. I am using a Prophesee Evk4 event camera.

When I try to run both drivers I am unable to open the event camera which is launched second in my ros2 launch file. My rgb camera which is launched first is successfully launched.

I am getting the following error: image(39)

24071693 is the rgb camera serial number. When I run the event camera launch file I typically do not specify a serial number, and the event camera driver is able to detect the camera.

System details

operating system/version: Ubuntu 22.04.4 LTS (Jammy Jellyfish)
ROS version: ROS 2 Humble

The event camera launch file works fine when launched individually and not running it together with the rgb camera.

Seems like I had used the same serial_number argument for both launch files resulting in a conflict.

Good. have been able to run exactly this combination in the past, so if it no longer worked it would imply a regression.
