Hmm - I think you might be missing a couple of key packages.

Can you do:
sudo apt-get -y install gstreamer1.0-libav
sudo apt-get -y install gstreamer1.0-vaapi

Yes it works after this. We have to update some scripts.
install_codecs.sh ?

#!/bin/sh

if [ $(id -u) != 0 ]; then
	echo "this script must be run using sudo"
	echo ""
	echo "usage:"
	echo "sudo "$0
	exit $exit_code
   exit 1
fi

GSTREAMER_VERSION=0.10
apt-cache show libgstreamer1.0-dev && GSTREAMER_VERSION=1.0

apt-get install libmpg123-dev gstreamer${GSTREAMER_VERSION}-plugins-ugly gstreamer1.0-vaapi gstreamer1.0-libav

awesome @dimitre
I did a PR for it with install_dependencies as its more of a core requirement than additional codecs.
see #7528
