I suspect your libav/gstreamer libraries have not been installed yet.

I seriously doubt it. More likely it's because the installation instructions are missing a few essential libraries, and I forgot to update them. You're not the first to report this problem, and without exception they all turned out to be missing libav/gstreamer libraries. My previous answer contains the libraries the last person with this problem did not have installed.

The list of libraries used when compiling RetroFE are these:
sudo apt-get install tortoisehg g++ cmake dos2unix zlib1g-dev libsdl2-2.0 libsdl2-mixer-2.0 libsdl2-image-2.0 libsdl2-ttf-2.0 \
            libsdl2-dev libsdl2-mixer-dev libsdl2-image-dev libsdl2-ttf-dev libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev \
            libgstreamer-plugins-good1.0-dev gstreamer1.0-libav zlib1g-dev libglib2.0-0 libglib2.0-dev sqlite3

Do you have audio when you play the videos in a separate video player?

Odd, sounds like a gstreamer/libav codec issue. Which distribution are you using?

lubuntu 17.04

Can you post the output of the following command?
apt list --installed | egrep -i "codec|gstreamer|libav"

I've taken the liberty of moving this discussion to a separate thread. :)

I had a look at your list, and notice at least two possible causes:
gstreamer1.0-alsa
gstreamer1.0-pulseaudio
are not installed; they manage the interface from gstreamer to your audio interface.

I would suggest installing the whole set of gstreamer, libav, and codec libraries though; that's probably the fastest way to resolve this. :)
