 "title": "Open an existing .rrd recording in the Dalaran viewer",
 "page_title": "How to open an existing .rrd recording in the Dalaran viewer with Dalaran",
 "summary": "Replay an upstream .rrd recording on one timeline without converting it first.",
 "who": "A robotics engineer who already has .rrd recordings from earlier runs and wants to review them in Dalaran.",
 "problem": "Old recordings are stored in a format that other tools cannot read in a synchronized way, so reviewing a run takes extra conversion work.",
 "outcome": "The recording opens directly in the viewer with entity paths, timelines, and data from all sensors visible together.",
 "steps": [
  "Run `pip install dalaran-sdk` to install the Python package that ships the viewer.",
  "Run `dalaran recording.rrd` in the folder that holds your recording, replacing recording.rrd with your file name.",
  "Scrub the timeline and check that the point clouds, camera frames, and transforms line up with each other.",
  "If you want a normalized copy, run `dalaran convert` as described in the README and open the new .dlr file."
 ],
 "agent_prompt": "Using the Flaminis/Dalaran repository, install dalaran-sdk with pip and open <recording_path> with the dalaran command. Report whether the viewer opens the file and list the entity paths you can see. Verify that the timeline shows data from more than one sensor.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "15 minutes",
 "basis": "readme",
 "caveat": "The README says blueprints saved in upstream recordings may be ignored while the data still loads, so the saved layout may not appear.",

 "lang": "rust",
 "requirements": [
  "Python with pip, or Rust with cargo, to install the Dalaran SDK or viewer",
  "A terminal to run the dalaran command",
  "An existing .rrd, .dlr, or MCAP recording, or a ROS 2 setup with rosbag2 files, for the replay use cases"
