I used Intel RealSense Depth Camera D435i to record some videos, exported them as a .bag file and try to convert them into .mp4.
I just found a GitHub repo that has done a similar thing called rosbag2video.
However, when I installed the dependencies it required and run the script, I got an error ModuleNotFoundError: No module named 'roslib'
I did try to follow the blog which is Installing ROS2 on Ubuntu 22.04 with no error emerged.
When I run python rosbag2video.py location1.bag, it still contains the same problems.
My system info will be:
Distributor ID: Ubuntu
Description: Ubuntu 22.04.2 LTS
Release: 22.04
Codename: jammy
=================== Update ===================
I discover one possible reason from rospy/Troubleshooting.
This probably means that your PYTHONPATH is not configured. Please make sure that your PYTHONPATH includes $ROS_ROOT/core/roslib/src.
It should be done when i
echo "source /opt/ros/humble/setup.bash" >> ~/.bashrc and source ~/.bashrc according to the blog?
Since no error emerge when installing ROS2 according the blog above, the update section is for reference only.
roslib is a module that contains ROS1 support packages and does not exist for ROS2. This is an error in the code on GitHub and you can fix it by simply removing line 14 of rosbag2video.py. You will also need to remove all other ROS1 dependencies included in that file as well.
