JeVois camera is not recognized in ArchLinux #6

Closed goekce closed 4 years ago

I am both in video and uucp groups. I can see that two /dev/ttyACM and two /dev/video devices are present. guvcview can access the camera. Still jevois-inventor does not show the camera.

I would like to debug the issue. Does jevois-inventor have any debug output that can be activated by the user?

yes, see the macro DEBU() in Config.H

To activate it, uncomment the non-trivial variant and comment-out the trivial one.

To use it, you will need to recompile the inventor. First, download the latest Qt directly from the Qt web site. Then in the inventor folder, ~/Qt/5.xx.xx/.../bin/qmake

and finally make

I noticed that on ArchLinux the package gst-plugins-bad is a dependence because /usr/lib/qt/plugins/mediaservice/libgstcamerabin.so requires libgstphotography-1.0.so.0

I found out this by running::

QT_DEBUG_PLUGINS=1 jevois-inventor

If this dependency is missing, then jevois-inventor cannot find any cameras.
