Hi all,
I have no success to run rtabmap with my two webcams stereo setup camera.

e warning mesage with approx_sync:=false

[ WARN] [1500890325.598924032]: /rtabmap/rtabmapviz: Did not receive data since 5 seconds! Make sure the input topics are published ("$ rostopic hz my_topic") and the timestamps in their header are set. If topics are coming from different computers, make sure the clocks of the computers are synchronized ("ntpdate"). Parameter "approx_sync" is false, which means that input topics should have all the exact timestamp for the callback to be called.
/rtabmap/rtabmapviz subscribed to (exact sync):
/rtabmap/odom,
/stereo_camera/left/image_rect_color,
/stereo_camera/right/image_rect,
/stereo_camera/left/camera_info,
/stereo_camera/right/camera_info,
/rtabmap/odom_info


If I make it approx_sync:=true here the error:

[ WARN] [1500890522.000583488]: odometry: Could not get transform from base_link to yuyv (stamp=1500890521.696677) after 0.200000 seconds ("wait_for_transform_duration"=0.200000)! Error=". canTransform returned after 0.201409 timeout was 0.2."
