Pcap replay error

[merriaux]

Hi everyone,
I try to replay a pcap file from a VLP16 record (ubuntu 16.04 and ros kinetic):
roslaunch velodyne_pointcloud VLP16_points.launch pcap:="2014-11-10-11-32-17_Velodyne-VLP_10Hz_Monterey Highway.pcap"

And I obtain this errors above.
I have done something wrong ? someone have a idea ?
thank for help
Pierre

With a ROS launch script, it's necessary to provide the full path name to the PCAP file. The node does not usually run in the current directory of the roslaunch command.

Questions like this are better asked on questions.ros.org.

[kmotillo]

I had the same problem and I solved it with your information, thanks jack-oquin

[aditya369007]

@kmotillo Im facing the same issue as that you have posted. Can you guide me on how to solve it?
I am using the $(pwd) for the full path name that roslaunch requires, but still facing issues on replaying pcap files.
Does the pcap file need to be stored in a specific place for this run ?

Much thanks in advance

update: I was able to figure out my mistakes and was successfully able to play the pcap data

[sgk-000]

I have same problem and I provided full path of pcap file, but I couldn't run this program. How can I solve it??

command:
roslaunch velodyne_pointcloud VLP16_points.launch pcap:=/home/koby/Download/vlp16_sample.pcap

@orz-000 - It's difficult to tell what caused the error without the log. Did you build the driver from source or install it from the ROS repository? Have you modified the launch file? Can you please paste the log that it mentions in the output here?

[sgk-000]

@JWhitleyAStuff -Thank you for replying!

are nothing.
I installed driver from the docker image made by velodyne. I executed it on docker and I haven't modified any files.

My docker file:

@orz-000 - with the following two lines:

RUN apt-get install -y ros-kinetic-velodyne
RUN cd ~/catkin_ws/src/ && git clone https://github.com/ros-drivers/velodyne.git

You are installing both the official, released version (ros-kinetic-velodyne) and cloning from source. I would recommend doing just the first. Try replacing the #install vlp16_software and #install loam_slam with the following:

#install vlp16_software
RUN apt-get install -y ros-kinetic-velodyne
#install loam_slam
RUN cd ~/catkin_ws/src/
RUN git clone https://github.com/laboshinl/loam_velodyne.git
RUN cd ~/catkin_ws
RUN rosdep install --from-paths ~/catkin_ws/src --ignore-src --rosdistro kinetic -y
RUN /bin/bash -c '. /opt/ros/kinetic/setup.bash; cd ~/catkin_ws; catkin_make'
RUN /bin/bash -c 'source ~/catkin_ws/devel/setup.bash'

@JWhitleyAStuff -Thank you for indicating and I fixed my docker file. I built and ran VLP16_points.launch, but I couldn't run all process and same error messages appeared.
What should I do? How can I solve it?

@orz-000 - I don't have an immediate solution for you. Please let me know your environment outside of Docker (Kerenel version, distribution, etc) and I'll do my best to replicate it on my machine. I'll put this ticket in "Needs Testing" for now. Can't promise a quick response on this one.

Edit: Actually, please open another ticket for this issue.

[MoonSheepJx]

hello, I have the same problem when I use
roslaunch velodyne_pointcloud VLP16_points.launch
Thank for any helps!
