RGBDSLAM with RosBag Files does not work. [closed]

edit

Hello all, I am new to ROS and i am trying to use the RGBDSLAM with ROSbag files i.e i want to first run the rosbag record and make a rosbag file and then run RGBD SLAM such that it will read this rosbag file and give me a map.

I found another post on the similar issue and used the launch file he used i.e

<launch>
  <node pkg="rgbdslam" type="rgbdslam" name="rgbdslam" cwd="node" required="false" output="log" > 
    <!-- see rgbslam_sample_config.launch for all available parameters and their default values -->
      <param name="config/topic_image_mono"              value="/camera/rgb/image_color"/>

<param name="config/topic_image_depth"             value="/camera/depth_registered/image"/>
<param name="config/topic_points"                  value=""/> <!--if empty, poincloud will be reconstructed from image and depth -->
<param name="config/camera_info_topic"             value="/camera/rgb/camera_info"/>
<param name="config/bagfile_name"                  value="/home/preetham/Desktop/filename.bag"/>
<param name="config/start_paused"                  value="true"/>

      <param name="config/wide_topic"                    value=""/>;
      <param name="config/wide_cloud_topic"              value=""/>;
      <param name="config/drop_async_frames"             value="true"/> <!-- Check association of depth and visual image, reject if not in sync -->
      <param name="config/feature_detector_type"         value="SURF"/><!-- If SIFTGPU is enabled in CMakeLists.txt, use SURF here -->
      <param name="config/feature_extractor_type"        value="SURF"/><!-- If SIFTGPU is enabled in CMakeLists.txt, use SURF here -->
      <param name="config/matcher_type"                  value="FLANN"/> <!-- FLANN (not avail for ORB features), SIFTGPU (only for SIFTGPU detector)  or BRUTEFORCE-->
      <param name="config/max_keypoints"                 value="2000"/><!-- Extract no more than this many keypoints (not honored by SIFTGPU)-->
      <param name="config/min_keypoints"                 value="1600"/><!-- Extract no less than this many ... -->
      <param name="config/optimizer_skip_step"           value="5"/><!-- optimize every n-th frame -->
      <param name="config/store_pointclouds"             value="true"/> <!-- if, e.g., only trajectory is required, setting this to false saves lots of memory -->
      <param name="config/individual_cloud_out_topic"    value="/rgbdslam/batch_clouds"/>;
      <param name="/config/use_gui" value="true"/>
    <!-- see rgbslam_sample_config.launch for all available parameters and their default values -->

<remap from="/camera/depth/camera_info" to="/camera/depth_registered/camera_info" />

  </node>
</launch>

And when i launch RGBDSLAM using this launch file it throws an error.

The following is the rosbag command i used and it records a rosbag file of size 300 Mb for 10 seconds which i feel is correct.

rosbag record -o /home/preetham/Desktop/filename_prefix /tf /camera/rgb/image_color /camera/rgb/camera_info /camera/depth_registered/image /camera/depth/camera_info

ould somebody help me out??
