Having the whole stacktrace posted somewhere to have a look (eg: on a public 
pastebin) would be helpful. It would also be helpful to know the specific 
GStreamer element being instantiated in that call to makegstreamerelement. 
Adding a printf() with the element name might be the most straightforward way 
to get it, if rebuilding WPE is an option for you. If not, maybe you can get 
it from gdb.

Maybe that specific element isn't available in the distro you're using on your 
Raspberry Pi. Once you know the element name, you can use the gst-inspect-1.0 
command line tool to check if it's available.

In any case, running WPE with the GST_DEBUG="*:INFO" environment variable (or 
"*:DEBUG" for more verbosity) will give a lot of insight about what the 
GStreamer libraries are doing under the hood.

Sorry, I can't help you about that. I mostly know only about multimedia. Input 
device management is out of my area of expertise.

Cheers.
