I don't know what that's about, sounds like a stale symlink (wouldn't
worry about it, although I wonder why this dir is in your plugin path
in the first place...)

The rtph265{pay,depay} elements from -bad have moved into the rtp
plugin from -good.

Remove the installed plugin file libgstrtpbad.so

The liveadder element/plugin has been replaced-by and merged-into the
audiomixer plugin in -bad.

Remove the installed plugin file libgstliveadder.so

The hls plugin has been renamed from libgstfragmented.so
to libgsthls.so.

Remove the installed plugin file libgstfragmented.so


These problems happen typically when plugins are moved and you don't do
"make uninstall" before you update your source tree and then just keep
'make install'-ing into the same prefix without removing any old files.

Once you removed these old/stale plugin files, run

  rm ~/.cache/gstreamer-1.0/registry*

and run gst-inspect-1.0 again.

Everything should work now.

Cheers
