Hi Jakob,
This is not something I really know much about, but I have seen similar errors
when cross-compiling things and it has been due to a badly setup
cross-compiling environment. In my case it has happened when the
cross-toolchain has linked to a library that was not compiled for the target
architecture. For example, in this case do you have an ARM version of the
gstreamer library installed in your cross-compile environment? Sorry, that is
not very clear - what I mean is that your cross compiler may have built an ARM
version of the aravis gstreamer plugin, but during the build it may have linked
to the X86 (or whatever your host architecture is) version of the gstreamer
libraries. When you then try to run the plugin on your ARM system it will break
(I think! At least I have had problems like this in the past).
What is your host system? If you are using Debian, then you can use xapt or
multi-arch to install the ARM version of the gstreamer libraries into the right
place for the cross-toolchain to link to them.
Cheers,
Nial
