Looking at your bag file info, your camera topic is /front_camera/camera/image_rect_color/compressed
; you should use this topic to extract images.
The third launch example that you posted doesn't close the first <node>
tag properly, which is why you're seeing an error there.
Therefore, your launch file should be something like:
<launch>
<node pkg="rosbag" type="play" name="rosbag" args="-d 2 /home/khmarehman/test.bag"/>
<node name="extract" pkg="image_view" type="extract_images" respawn="false" output="screen" cwd="ROS_HOME">
<remap from="image" to="/front_camera/camera/image_rect_color/compressed"/>
</node>
</launch>
And this may or may not work because you've only recorded compressed images in your bag file. You may also need to set the image_transport
parameter to compressed
to the extraact_images node.
