Installation of GStreamer Libav

Install GStreamer Libav by running the following commands: 

mkdir build &&
cd    build &&

meson  --prefix=/usr       \
       --buildtype=release \
       -Dpackage-origin=https://www.linuxfromscratch.org/blfs/view/systemd/ \
       -Dpackage-name="GStreamer 1.20.4 BLFS" &&

To test the results, issue: ninja test. One test, elements_avaudenc, is known to fail with ffmpeg-5.1.

Now, as the root user: 

ninja install
