[ROS2] ROS1 bag conversion into ros2 bag format using rosbag2 in crystal

edit

Hi Team,

We are using ros2 crystal rosbag2 pkg ( https://github.com/ros2/rosbag2 ) and trying to run info/play/record ROS1 .bag file. Here i am enable to see ros1 .bag meta details into ros2 bag info command as below but unable to play/record for the same.

• $ source /opt/ros/melodic/setup.bash
• $ source /opt/ros/crystal/setup.bash
• $ source ~/rosbag_ws/install/setup.bash

$ ros2 bag info -s rosbag_v2 Mapping_ros1.bag

where Mapping_ros1.bag is the ROS1 .bag file.

The command above will print something like the following:

But when we have tried to execute ros2 bag play -s rosbag_v2 Mapping_ros1.bag command to play ros1 .bag file in ros2 crystal, getting the below error.
