How to read rosbag with customised topic names

[petitchamp]

I try to read a rosbag recorded from davis 346 camera.

The topics in the rosbag are like :

• /davis/left/events
• /davis/left/image_raw
• /davis/left/imu
• /davis/right/events
• /davis/right/image_raw
• /davis/right/imu

I have modified /dvs_left/events in renderer_mono.launch and renderer_stereo.launch to /davis/left/events and also image_raw topics , however, when I launched roslaunch with the launch file, I have nothing displayed on the screen. And the process dvs_renderer is still launched with /dvs_left/events

catkinws/devel/lib/dvs_renderer/dvs_renderer events:=/dvs_left/events dvs_rendering:=dvs_rendering_left __name:=dvs_renderer_left _

Is there anything wrong with my procedure?

Thanks for you attention.
