Description
Expose the functionality in #302, reading a selective set of topics, to the command line as options under
ros2 bag play.The specific command format is up to suggestion. I did not find such a playback flag in the ROS 1 bag tutorial, but there was such a format for recording:
where
-Ospecifies the output file, and the remaining arguments are the topics to record.Maybe playback can use
-Ifor the input file? That flag is free right now.Related Issues
Depends on #302
Completion Criteria
User is able to specify a subset of topics on the command line to play back.
If no topics are specified, all topics should be played back as normal.
Implementation Notes / Suggestions
Command line args should be added to
ros2bag/ros2bag/verb/play.py.Topic list should be added to
rosbag2_transport/include/rosbag2_transport/play_options.hpp.Functionality should be added to
rosbag2_transport/src/rosbag2_transport/player.cpp.Testing Notes / Suggestions
End-to-end tests should be added to
rosbag2_tests/test/rosbag2_tests/test_rosbag2_play_end_to_end.cpp.See
rosbag2_storage_default_plugins/test/rosbag2_storage_default_plugins/sqlite/test_sqlite_storage.cppfor existing tests for the filtering functionality.The text was updated successfully, but these errors were encountered:
