It looks like the 'undefined symbol' problem was resolved then, yes?

This probably indicates that you are missing some plugins/elements, and
that the application in question doesn't check whether the element it
tried to create is actually available.

You can run it in gdb with G_DEBUG=fatal_warnings to make it stop at
the first warning, and then look at the 'bt' stack trace to see which
line of code triggered it. Then check with gst-inspect-1.0 ELEMENTNAME
that the element actually exists. Perhaps you need to install some of
the plugins, or set GST_PLUGIN_PATH.

Cheers
