image_view not functioning (segmentation fault) #516

benhamlen · 2020-04-14T00:09:10Z

I'm running ros melodic on an nvidia xavier agx, ubuntu 18.04

Running roslaunch video_stream_opencv video_file.launch fails with the following output

... logging to /home/sd/.ros/log/d688c298-7de0-11ea-b5c8-00044be59e11/roslaunch-sd-17072.log

log file: /home/sd/.ros/log/d688c298-7de0-11ea-b5c8-00044be59e11/videofile-videofile_image_view-3*.log

I've tried to view the log file mentioned at the end of the output and it is empty/does not exist.

Setting the the visualize output line (line 32) of the video_file.launch file to false (shown below) eliminates this error and the program runs without error, successfully publishing the video to /videofile/image_raw

 <!-- visualize on an image_view window the stream generated -->
        <arg name="visualize" value="false" />

I've verified its successfully publishing to the image topic after setting that visualize launch option to false by:

checking rostopic echo /videofile/image_raw, there is output
succesfully running object detection on the image topic with
rosrun ros_deep_learning detectnet /detectnet/image_in:=/videofile/image_raw _model_name:=pednet

Just to isolate the issue more, I then tried to run image_view separately on the /videofile/image_raw topic

rosrun image_view image_view image:=/videofile/image_raw

which fails with

[ INFO] [1586820077.545330229]: Initializing nodelet with 8 worker threads.
[ INFO] [1586820077.758800634]: Using transport "compressed"
Segmentation fault (core dumped)

I read on #264 that ros kinetic had this issue because its compiled against opencv2, however I'm using melodic. Surely its compiled against opencv3 right?

For completeness, here is the full log files mentioned at the top of the ROS output

I'm confused, https://wiki.ros.org/video_stream_opencv is not in this repo. Did you mean to file a ticket there?

benhamlen · 2020-04-14T00:21:03Z

@SteveMacenski Ah, sorry for the confusion. I am almost certain the issue lies with image_view. Just wanted to provide context of where the image topic i'm feeding image_view is coming from

I should add that the purpose of adding the line about changing the launch file option from true to false is there because changing it to false makes that launch file no longer call image_view, which, in turn, makes it run without error

benhamlen · 2020-04-17T16:53:38Z

@SteveMacenski do you have any updates on image_view's issues? I saw in a different thread that it was possible some dev was the last person to push changes to it and might have messed it up? Just to reiterate, this issue thread is about image_view. Sorry for the earlier confusion

SteveMacenski · 2020-04-17T20:04:12Z

Can you reproduce using a much simpler demo? You have alot of stuff going on in your description, boiling it down to a simple issue with just this tool.

Also verify as you mention that you’re compiling against the right version of opencv. How’d you install it, versions, etc.

Also, run gdb on it and see where its segfaulting. Maybe its obvious where it is then.

aytimothy · 2020-05-03T05:06:40Z

It could be something to do with the environment that we're running in? I started from a Ubuntu Server setup and installed ROS, a desktop+RDP (because headless setup) and all that, though my intentions are that of #498 plus image_compressed.

From both of these dying after image_view segfaults, from viewing in rqt_graph, I'd assume they're related.

I just installed ros (sudo apt-get install ros-melodic-desktop-full) as per normal, installed @awesomebytes' drivers ran it, and finally SIGSEGV in image_view. I'll see if I can extract the crash dump.

You can also find the initial things I collected in the above linked issue.

aytimothy · 2020-05-03T05:29:49Z

I have a crash dump here: https://aytimothy.xyz/files/pub/_opt_ros_melodic_lib_image_view_image_view.1001.crash

Edit: Link is now to GitHub Gists. You can still download from the external site.

awesomebytes · 2020-05-03T05:51:14Z

@aytimothy Have you tried recording a short rosbag of the image_raw camera_info and maybe image_raw/compressed topics and then trying to run image_view playing this rosbag? If it crashes that way, it's a very easy way for developers to reproduce the issue and fix it. (And the rosbag can be attached to the comment of the issue so it doesn't depend on external hosts).

aytimothy · 2020-05-04T06:01:35Z

Okay, there's no point in posting a rosbag, because there's literally nothing to report (the rosbag file is empty), besides it saying "topic is not used" in the console even after started.

But what seems to be happening is that after it dies the first time, roslaunch (or something) starts it up again a few seconds later, and everything works fine. So, for this second launch, I doubt it's related to this. I think that crash dump file might be more useful than grabbing an empty rosbag.

As for reproduction, I managed to reproduce it by literally flashing a new SD card, grabbing Ubuntu Server, setting up ROS, installing the driver and then running it. What's odd is that it sometimes happens on a Raspberry Pi 3, but always on a Raspberry Pi 4.

JWhitleyWork · 2020-05-06T06:17:00Z

@aytimothy Can you please test to see if the issue is resolved now that #526 is merged into Melodic?

awesomebytes · 2020-05-06T07:00:44Z

@aytimothy Can you try to record a rosbag with having visualize=false (so some image from the video_stream_opencv driver gets published) and try to start image_view with the rosbag playing to see if it crashes? Just to confirm that it isn't related somehow to the format of the image published. If it would crash image_view it would be a perfect test case.

But what seems to be happening is that after it dies the first time, roslaunch (or something) starts it up again a few seconds later, and everything works fine.

I don't know what may cause that behaviour. The launchfiles from video_stream_opencv don't contain a respawn=true value. There is also an optional parameter reopen_on_read_failure on the dynamic reconfigure, but it's also False by default. That's all I can think that may do something of that nature.

I admit that if this issue has to do with some kind of timing/racing condition issue of a driver starting to advertise images and image_view trying to connect/callback/some_other_behaviour the rosbag will be useless. But if it's related in some way with the type of data contained in the image (which both reports come from video_stream_opencv so they are generated with the same code) it should be reproducible with a rosbag. Maybe the first image published has some issue? Dunno, just trying to help.

JWhitleyWork · 2020-05-06T21:06:23Z

@awesomebytes The visualize parameter doesn't exist in image_view and it never should have, IMO. The image_view nodelet is not intended as an image processor - there are plenty of other nodelets in this stack for that purpose - it is intended only as an "image viewer." It should produce a GUI window which displays images from a given topic and that should be it's only purpose. If some minor image processing is necessary to achieve that goal then it can be done internally but the images that are processed therein should not be published to a topic lest it be misused as an "image processing" node.

awesomebytes · 2020-05-07T00:23:42Z

@JWhitleyWork the visualize parameter exists in the launchfiles from video_stream_opencv. As I believe we were having some kind of communication issue I was more detailed with the explanation of how and why to record a rosbag that may contain data that may trigger the crash in image_view.

JWhitleyWork · 2020-05-07T00:46:33Z

@awesomebytes Thanks for the clarification.

@awesomebytes Hi I'm having the same issue. I've tried recording a rosbag as per your advice, but I get an error after 200 msgs:

[ERROR] [1589731616.096380328]: Could not capture frame

I've attached a rosbag of 30 msgs and the original mp4 here:
small.mp4.zip
test.bag.zip

Running image_view on the rosbag's /videofile/image_raw as input gives an immediate seg fault.

I'll take a look see.

awesomebytes · 2020-05-18T06:18:38Z

@hoonkai Thanks a lot for reporting and attaching the rosbag! I hope this is helpful for the developers :)
I'll look into the Could not capture frame error when I have some free time.

hoonkai · 2020-05-18T09:48:45Z

@awesomebytes Thanks. Can you upload a working mp4 for me to test out video_stream_opencv + image_view? I've tried 5 different mp4s but none of them works and they all crash in the same fashion.

@awesomebytes Thanks. Can you upload a working mp4 for me to test out video_stream_opencv + image_view? I've tried 5 different mp4s but none of them works and they all crash in the same fashion.

The mp4 found in video_stream_opencv was working I thought, up until your feedback. I can't take a look right now, but I'll do!

@hoonkai Please pull master and test. Once you've verified that the issue is resolved, I'll make a new release for Melodic.

@aytimothy Can you please test to see if the issue is resolved now that #526 is merged into Melodic?

That fixed it for me!

Awesome. I'll make release 1.15.0 for melodic now that includes this fix.
