Bag Details

This window displays detailed information about a bag.

Properties

The properties are a list of information about a bag file. Most of these fields were statically determined by when reading the modified and cannot be modified, but Bold fields are used to store dynamically determined information and can be modified.

Message Types

All of the types of messages that were read from a bag file. It also displays the MD5 Sum of each message type, since messages with the same name could have different types if the message definition changed.

Topics

All of the topics in the bag file. In addition to displaying a list of topics, the action icons in the right can be used to view images and videos from topics that have a sensor_msgs/Image or sensor_msgs/CompressedImage type.

The Bag Database will do its best to use OpenCV to convert images into a format that can be rendered into a bag file, but OpenCV may not be able to parse some image formats. Consult the server log if images do not render as expected.

Tags

If a bag has had tags set on it, they will all be displayed here. This panel can also be used to add or remove tags.
