Hi everybody,

as I described here I am publishing an Image with image_publisher.

I want to show that image from a camera topic with image_view. But when I try that an window of Image_view opens, gets grey, than black, than the windows disappears an the process is closed (Terminal output see below). I tried it with rosrun and with a launch file. (Details below) It should both work, it is possible that it's the same failure.

Has anybody an Idea why It doesn't work?


rosrun image_view image_view image:=/mix_image/image_raw
[ INFO] [1588677089.341995716]: Initializing nodelet with 4 worker threads.
[ INFO] [1588677089.365761375]: Using transport "raw"
Speicherzugriffsfehler (Speicherabzug geschrieben)

The Error says "Segmentation fault (core dumped)"

And when I try to view the image with a launchfile

  <node name="image_view" pkg="image_view" type="image_view" respawn="false" output="screen">
    <remap from="image" to="/mix_image/image_raw"/>
    <param name="autosize" value="true" />

I get this error message:
