Can't find gstreamer plugins after installing them

I am trying to use GStreamer in Ubuntu 16.04, and I need something like this:

gst-launch-1.0 -v tcpclientsrc host=x.x.x.x port=5000 ! gdpdepay ! rtph264depay ! avdec_h264 ! ffmpegcolorspace ! autovideosink sync=false

however when I type gst-inspect-1.0 avdec_h264 or any of the plugins in the list, it results in No such element or plugin

I already tried installing libav, ugly, bad, good:

sudo apt-get install gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-plugins-base gstreamer1.0-plugins-bad gstreamer1.0-plugins-good

I also looked in /usr/lib/x86_64-linux-gnu/gstreamer-1.0, and found nothing

Any suggestions on what could be wrong?

If you have anaconda installed and you do which gst-launch-1.0, it will most likely point to anaconda location which only had gst-plugins-base. So directly launching the /usr/bin/gst-launch-1.0 fixed the issues for me as it was able to find the bad, good etc plugins.
