It reads bag files assuming they are created with sqlite. However, because the messages are encoded in the db and there is not support for deserialization in Python, there isn't any ability to record, play or create a smaller bag from the original.
So currently you can view a bag file and see a description of topics and the timeline of messages published with it. The controls are functional as well. There just isn't any way to see what's in a bag file or really do anything else with it.
