gavl-1.4.0

Introduction to Gavl

Gavl is short for Gmerlin Audio Video Library. It is a low level library that handles the details of audio and video formats like colorspaces, samplerates, multichannel configurations etc. It provides standardized definitions for those formats as well as container structures for carrying audio samples or video images inside an application.

Installation of Gavl

First, fix an issue with gcc-14 and later:

sed -i "/stdio/a #include <string.h>" src/fill_test.c

Now, install Gavl by running the following commands:

LIBS=-lm                         \
./configure --prefix=/usr        \
            --without-doxygen    \
            --with-cpuflags=none \
            --docdir=/usr/share/doc/gavl-1.4.0 &&
make

This package does not come with a test suite.

Now, as the root user:

make install

Command Explanations

LIBS=-lm: This variable ensures the math library is searched when linking.

--without-doxygen: This switch disables use of Doxygen. Omit if Doxygen is installed and you wish to build the API documentation.

--with-cpuflags=none: This switch fixes a problem identifying capabilities of the system architecture.
