gstreamer not working after upgrade to 1.8.0

[Dani MR]

Hi everyone,
after working with Gstreamer 1.6.3 version, I decided to upgrade to the latest stable release 1.8.0.
What has happened is that the projects that used to run with the older version are not working anymore.
This is the log I get after trying to run the projects:

** (gst-plugin-scanner:5069): CRITICAL **: Couldn't g_module_open libpython. Reason: /usr/lib/libpython2.7.so: cannot open shared object file: No such file or directory

Moreover if I try to run gst-inspect-1.0 autovideosink for example (after export LD_LIBRARY_PATH=/usr/lib), before getting the info I have this returned:

** (gst-plugin-scanner:5127): CRITICAL **: Couldn't g_module_open libpython. Reason: /usr/lib/libpython2.7.so: cannot open shared object file: No such file or directory

(gst-plugin-scanner:5127): GStreamer-CRITICAL **: gst_element_register: assertion 'g_type_is_a (type, GST_TYPE_ELEMENT)' failed

My OS is Ubuntu 14.04 64b and gstreamer has always been installed with prefix=/usr, specifically what I've installed is: gstreamer, base, good, ugly, bad, libav, rtsp-server and python. I am using Eclipse for developing.

Thanks for your help

Dani

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
