rosrun image_view image_view image:=/raspicam/image_raw gives a black screen [closed]

edit

Hello, I'm trying to publish visual odometry from my rasberry pi camera to my PC, it is possible to stream a video. I have followed all the steps from this site ( https://www.instructables.com/id/ROS-... ) but I'm stuck with the last code from step 2 ( rosrun image_view image_view image:=/raspicam/image_raw) this line gives an error:

image_raw:31323): GLib-GObject-CRITICAL **: 11:50:57.883: g_object_unref: assertion 'G_IS_OBJECT (object)' failed

it also says that there is no data.

Can someone help me please
