Hello,

I am trying to run RTAB-Map using an RGB video recorded with a mobile phone camera (no depth).

Setup:
- RTAB-Map GUI (not ROS)
- Source: RGB -> Video file
- Video resolution: 1080x1920 (portrait)
- Frame rate: ~30 FPS
- Camera calibration provided (YAML), resolution matches the video
- Visual odometry: 2D-2D (ORB)

Problem:
- RTAB-Map plays the video correctly
- Loop closure window shows feature matches
- BUT odometry is not computed (Odometry view stays empty)
- Console shows: "Missing some information (images empty or missing calibration?)"
- If I disable odometry, the video plays normally

Question:
Is monocular RGB odometry officially supported from a recorded phone video?
Are there specific requirements (rotation, rectification, orientation, grayscale, timestamping) for video files?
I am using RTAB-Map GUI on Ubuntu 22.04 (non-ROS).
The video was recorded in portrait mode on a phone camera.

Thank you.
