I compiled this command
ros2 launch usb_cam demo_launch.py

I dont know why, but I am also encounter this issue. The quick way to fix it is to not using mjpeg2rgb, yes I know although it says the camera pixel_format is supported...

[flynneva]

@Narek-939 @TZECHIN6 on it! Sorry this was a result of my latest work on trying to address some memory leaks

[TZECHIN6]

@flynneva take your time. I appreciate your work to the community :D

[Narek-939]

@flynneva @TZECHIN6 thanks)

[Narek-939]

I will look forward to fixing this issue)

[flynneva]

The invalid pointer issue should be fixed now on the ros2 branch. Going to close this issue, feel free to open more if you run into anything else!
