I think the problematic plugin was androidmedia then, as expected.
Without this one you won't have support for the (hardware) codecs that
are available on the device and it would be good to understand why
exactly it's failing.

You'll have to enable GStreamer debug output to get more useful
information about what goes wrong there, but as before there are also
lots of SIGPIPE happening here.

I think you a) need to enable more GStreamer debug output and b) run
this in a debugger to see where exactly it's crashing.
