image_view crashes #102

I have a bag with 4 video feeds, 1 obtained from a drone camera and 3 from a pi camera. Whenever I try to view the images using the feeds from the camera using image_view, it crashes.
Using rqt_view does not have any problem whatsoever.
Running through gdb (I compiled image_view with debug information), I get the following backtrace:
#0 0x00007ffff614054d in cv::resizeAreaFast_Invoker<unsigned char, int, cv::ResizeAreaFastVec >::operator()(cv::Range const&) const ()

#8 0x00007ffff69a6fbd in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:111

Funny thing though, if I run in debug mode through QtCreator, it does not crash...

I am using Kubuntu 14.04 with all updates with indigo (also fully updated) as of today, 1/oct.

Any ideas? I can share the bag I am using (~750Mb) if anyone wants to test.
Although I can use rqt_image, image_view would be much better for my needs, and it was working without any problems in ros hydro and kubuntu 12.04 (for that same bag).

Not sure if it is related to #101 but please provide a link to your bag. Thx.

The bag can be downloaded here: https://dl.dropboxusercontent.com/u/9090110/cam_tests_flight2_2014-09-04-16-46-28.bag

The camera2, camera3 and camera4 are the ones which are problematic with image_view in ros indigo.

ok, I am on Kubuntu 14.04 too and I do not get any crashes ....
I do:

rosbag play -l cam_tests_flight2_2014-09-04-16-46-28.bag &
rosrun image_view image_view image:=/camera2/image/compressed

The window stays gray but I get this error:

[ERROR] [1412404632.430314076]: Client [/image_view_1412404632114300336] wants topic /camera2/image/compressed to have datatype/md5sum [sensor_msgs/Image/060021388200f6f0f447d0fcd9c64743], but our version has [sensor_msgs/CompressedImage/8f7a12909da2c9d3332d540a0977563f]. Dropping connection.

How did you record your bag ?

Since it is a compressed video feed, you need to view it using:
rosrun image_view image_view image:=/camera2/image _image_transport:=compressed

Hi, image_view image:=/camera2/image _image_transport:=compressed now works for me. Been busy lately, sorry.

I updated to the latest versions and I still have the same problem. I am running on Xubuntu 14.04 64bit installation (all updates as of 31/october). Can the issue be reopened?

you get the exact same backtrace ? on the same bag ?

The backtrace is not exactly the same but very similar (only the first line changes). I tested it with camera2 on the exact same bag. Note that sometimes it is able to run, but most of the times it fails (the same command, the same bag), which indicates that it could be some race condition.

I have 1.12.11 and it doesn't crash anymore when using compressed images. I guess the bug has been resolved, but the debs are not updated yet.

Sorry to say, but I have installed ros-indigo-image-view 1.12.11 and I still get exactly the same output. Note that sometimes it is able to show the images, but most of the times it crashes. Try to get the bag playing first and then run the image_view node to see it happening.

Can the issue be reopened? Can I do anything else to determine what can be done?

I do not get that error anymore. The easiest would be to revert image_view to previous versions and see when the break happened.

Sorry for the late reply. I tried with version 1.12.12 and I still get a crash occasionally, but it rarely happens. Running through GDB I wasn't able to get it to crash at all, so I would leave this one closed for now.
Thanks for your help.
