Installation of GStreamer Libav

[Note]

Note

If you do not have an Objective-C compiler installed, the build system for this package will emit a warning about a failed sanity check. This is harmless, and it is safe to continue.

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/svn/ \
       -Dpackage-name="GStreamer 1.20.0 BLFS" &&
ninja

To test the results, issue: ninja test

Now, as the root user: 

ninja install

Command Explanations
