Chapter 6. Audio

Opus-1.6.1

Introduction to Opus

Opus is a lossy audio compression format developed by the Internet Engineering Task Force (IETF) that is particularly suitable for interactive speech and audio transmission over the Internet. This package provides the Opus development library and headers.

Important

For the lib32 installation instructions, they require new Meson cross files from MLFS, as --libdir=/usr/lib32 has been moved to the cross files and no longer appear in the instructions. Install the new cross files so that 32-bit libraries don't get installed in /usr/lib.

Optional
doxygen and texlive (or install-tl-unx)

Installation of Opus

Install Opus by running the following commands: 

mkdir build &&
cd    build &&

meson setup --prefix=/usr        \
            --buildtype=release  \
            -D docdir=/usr/share/doc/opus-1.6.1 \
            .. &&

ninja

Now, as the root user: 

ninja install
