I was using a plotjuggler built with catkin above (and commingled with other ros1 packages), but had success building with colcon (and overlaying a ros2 iron build), though there's something wrong with sourcing install/setup.bash after the colcon build:
not found: "/home/lucasw/ros/ros2_plotjuggler/install/plotjuggler/share/plotjuggler/local_setup.bash"
I can't start plotjuggler via ros2 run plotjuggler plotjuggler because of that, but I can launch it where the executable was symlinked into install/ inside my colcon workspace:
./install/plotjuggler/lib/plotjuggler/plotjuggler
And then I can load both ros2 and ros1 mcap bags as desired (this colcon build only has a ros2 subscriber though, so I would have to go back to the catkin built plotjuggler for live ros1 topics).
Problem description
I converted a ros2 db3 to mcap using
mcap convert
which results in this error when trying to load in Plotjuggler:Then similar for a ros1 bag:
The mcap files report as
That's using a version of the mcap cli tool built from latest source (should I go to an older version, a release like foxglove/mcap@91b3a9f ?).
The ros2 mcap works fine with
ros2 bag play
