I happened to have downloaded a bag file of Kinect which was recorded with the help of libfreenect driver. If i develop a node which is for kinect and that uses Openni driver. Will there be differences in the type of topics that are created by both drivers in terms of images and point clouds?
To answer your question directly, yes, the different kinect drivers have different ROS APIs (meaning the topics they publish are different). You can take a look at the wiki pages for the different drivers (kinect_camera which uses libfreenect, and openni_camera, which uses the openni drivers) to compare.
Whenever using a bag file you may play that file
rosbag - and then use rostopic to find revelent info
Update: Lorenz is correct, you can simply use rosbag info
You use the rosbag info command and display the output in your question and using that I will be able to help as I have only worked with openni drivers.
