Not sure to understand what rtabmap does in extracting images from the rosbag, which should be independent as seen in the link you shared. Maybe your computer cannot save the images on hard drvie fast enough that they are received from the rosbag. You could increase queue_size of the callbacks in the video recorder or reduce speed of the playback of the rosbag.

On rtabmap side, it processes images at 1 Hz by default, so for 95s, there would be 95 images in the database.
