Libraries get installed into /usr/local/lib (depending on the
prefix/libdir), Plugins get installed into /usr/local/lib/gstreamer-1.0/
- this should not have changed (and I would be surprised if it did).

Yes, you may need to set things up so it gets found, although on most
distros that should be the case already for /usr/local.
Check /etc/ld.so.conf* and your PATH.

Then it depends which libgstreamer-1.0.so gets used, where it will look
for plugins. It will only look for plugins in its own prefix, so won't
pick up things from other prefixes unless you force it via
GST_PLUGIN_PATH.

I usually don't recommend you mix from-source installs of GStreamer with
from-package installs, since it gets messy soon, esp. if you update the
packages then.
