42. Multimedia Libraries and Drivers

Many multimedia programs require libraries and/or drivers in order to function properly. The packages in this section fall into this category. Generally you only need to install these if you are installing a program which has the library listed as either a requirement, or as an option to enable it to support certain functionality.

42.1 ALSA-1.2.7

The Linux kernel now provides ALSA support by default. However, applications need to interface to that capability. The following six sections of the book deal with the separate components of ALSA: the libraries, the plugins, the utilities, the tools, the firmware and the OSS compatibility libraries.

42.2 alsa-lib-1.2.8

Introduction to ALSA Library

The ALSA Library package contains the ALSA library used by programs (including ALSA Utilities) requiring access to the ALSA sound interface.

This package is known to build and work properly using an LFS 11.3 platform.

Package Information

ALSA Library Dependencies

Optional

Doxygen-1.9.6, Python-2.7.18, and alsa-ucm-conf

User Notes: https://wiki.linuxfromscratch.org/blfs/wiki/alsa-lib

Kernel Configuration

If needed, enable the following options in the kernel configuration and recompile the kernel:

Device Drivers --->
    <*/M> Sound card support --->                  [CONFIG_SOUND]
        <*/M> Advanced Linux Sound Architecture ---> [CONFIG_SND]
                Select settings and drivers appropriate for your hardware.

In the Device Drivers ⇒ Sound card support ⇒ Advanced Linux Sound Architecture section of the kernel configuration, select the settings and drivers appropriate for your hardware. If necessary, recompile and install your new kernel.

Installation of ALSA Library

Install ALSA Library by running the following commands:

./configure &&
make

If you have Doxygen installed and you wish to build the library API documentation, run the following commands from the top-level directory of the source tree:

make doc

To test the results, issue: make check.

Now, as the root user:

make install

To install the API documentation, run the following command as the root user:

--disable-xmlto: Omit this switch if you have installed xmlto-0.0.28 and wish to regenerate the man pages.

--disable-bat: Omit this switch if you have installed fftw-3.3.10 and wish to install the Basic Audio Tester (BAT).

--with-curses=ncursesw: This switch forces the use of wide-character ncurses libraries.

Configuring ALSA Utilities

Config Files

/var/lib/alsa/asound.state

Configuration Information

Note that all channels of your sound card are muted by default. You can use the alsamixer program to change this. Use speaker-test to check that your settings have been applied correctly. You should hear “pink noise” on your speakers.

The alsactl program is normally run from a standard udev rule. The first time it is run, it will complain that there is no state in /var/lib/alsa/asound.state. You can prevent this by running the following command as the root user:

alsactl -L store

The volume settings should be restored from the saved state by Udev when the device is detected (during boot or when plugged in for USB devices).

All sound devices are not accessible for any user except root and members of the audio group. Add any users that might use the sound devices to that group:

usermod -a -G audio <username>

Note

You may need to log out and back in again to refresh your group memberships. ‘su <username>’ should work as well.

On systems which have multiple sound cards, you may need to adjust the default audio device so that you can get output from your speakers. To set the default device, first check the /proc/asound/cards file to determine which number you need to set. After you know this information, set the default card with the following command as the root user:

cat > /etc/asound.conf << "EOF"
# Begin /etc/asound.conf

defaults.pcm.card 1
defaults.ctl.card 1

# End /etc/asound.conf
EOF

This package is known to build and work properly using an LFS 11.3 platform.

Package Information

ALSA Tools Dependencies

Required

alsa-lib-1.2.8

Optional

GTK+-2.24.33 (to build echomixer, envy24control and rmedigicontrol), GTK+-3.24.36 (to build hdajackretask) and FLTK-1.3.8 (to build hdspconf and hdspmixer)

User Notes: https://wiki.linuxfromscratch.org/blfs/wiki/alsa-tools

Installation of ALSA Tools

Note

When installing multiple packages in a script, the installation needs to be done as the root user. There are three general options that can be used to do this:

  1. Run the entire script as the root user (not recommended).

  2. Use the sudo command from the Sudo-1.9.13p1 package.

  3. Use su -c “command arguments” (quotes required) which will ask for the root password for every iteration of the loop.

One way to handle this situation is to create a short bash function that automatically selects the appropriate method. Once the command is set in the environment, it does not need to be set again.

as_root()
{
  if   [ $EUID = 0 ];        then $*
  elif [ -x /usr/bin/sudo ]; then sudo $*
  else                            su -c \\"$*\\"
  fi
}

export -f as_root

First, start a subshell that will exit on error:

bash -e

Now, remove a tool that needs Qt2 or 3 and two unneeded files (for the BLFS instructions below):

rm -rf qlo10k1 Makefile gitcompile

The ALSA Tools package is only needed by those with advanced requirements for their sound card. The tools can be built all together at once, but if only a subset is needed, you need to cd into the directory of each tool you wish to compile and run the commands. Here, we present instructions to build all tools.

Install all ALSA Tools by running the following commands:

for tool in *
do
  case $tool in
    seq )
      tool_dir=seq/sbiload
    ;;
    * )
      tool_dir=$tool
    ;;
  esac

  pushd $tool_dir
    ./configure --prefix=/usr
    make
    as_root make install
    as_root /sbin/ldconfig
  popd

done
unset tool tool_dir

Finally, exit the shell that was started earlier:

exit

./bootstrap                                &&
./configure --prefix=/usr --disable-static &&
make

This package does not come with a test suite. However, basic functionality can be tested by encoding a sample WAV file (the sample file is installed by the alsa-utils-1.2.8 package:

./frontend/faac -o Front_Left.mp4 /usr/share/sounds/alsa/Front_Left.wav

Then, decode the result using the faad program from the FAAD2-2.10.1 package and play back the decoded file (requires the aplay program from the alsa-utils-1.2.8 package:

faad Front_Left.mp4
aplay Front_Left.wav

aplay should identify the file as “Signed 16 bit Little Endian, Rate 48000 Hz, Stereo”, and you should hear the words “front left”.

Now, as the root user:

make install

Command Explanations

--disable-static: This switch prevents installation of static versions of the libraries.

Other AAC encoders

The quality of FAAC is not up to par with the best AAC encoders currently available. Also, it only supports AAC and not High Efficiency AAC (also known as aacPlus), which provides better quality at low bitrates by means of using the “spectral band replication” technology. There are the following alternative programs for producing AAC and HE-AAC streams:

Note, however, that iPod supports only Low Complexity AAC profile, which is the default in FAAC, but may not be the default in Nero AAC Encoder and is completely unavailable in the 3GPP encoder.

User Notes: https://wiki.linuxfromscratch.org/blfs/wiki/gst10-plugins-base

Installation of GStreamer Base Plug-ins

Note

If you need a plugin for a given dependency, that dependency needs to be installed before this package.

Install GStreamer Base Plug-ins by running the following commands:

mkdir build &&
cd    build &&

meson  --prefix=/usr       \
       --buildtype=release \
       -Dpackage-origin=https://www.linuxfromscratch.org/blfs/view/11.3-systemd/ \
       -Dpackage-name="GStreamer 1.22.0 BLFS"    \
       --wrap-mode=nodownload &&
ninja

To test the results, issue: ninja test. The tests require an X terminal running, or all of the GL tests will fail. Five tests may produce timeouts on some systems depending on their graphics hardware and speed.

Note

When installing, the build process does some additional linking. If you do not have Xorg in /usr, the LIBRARY_PATH variable needs to be defined for the root user. If using sudo to assume root, use the -E option to pass your current environment variables for the install process.

Now, as the root user:

ninja install

Command Explanations

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

PulseAudio is a sound system for POSIX OSes, meaning that it is a proxy for sound applications. It allows you to do advanced operations on your sound data as it passes between your application and your hardware. Things like transferring the audio to a different machine, changing the sample format or channel count and mixing several sounds into one are easily achieved using a sound server.

This package is known to build and work properly using an LFS 11.3 platform.

Package Information

PulseAudio Dependencies

Required

libsndfile-1.2.0

alsa-lib-1.2.8, dbus-1.14.6, GLib-2.74.5, Speex-1.2.1 and Xorg Libraries

Optional

User Notes: https://wiki.linuxfromscratch.org/blfs/wiki/pulseaudio

Installation of PulseAudio

Install PulseAudio by running the following commands:

mkdir build &&
cd    build &&

meson --prefix=/usr       \
      --buildtype=release \
      -Ddatabase=gdbm     \
      -Ddoxygen=false     \
      -Dbluez5=disabled   &&
ninja

To test the results, issue: ninja test. One test fails if the tests are not run as the root user, but this can be ignored.

Now, as the root user:

ninja install

Running PulseAudio as a system-wide daemon is possible but not recommended. See https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/SystemWide/ for more information. While still as the root user, remove the D-Bus configuration file for the system wide daemon to avoid creating unnecessary system users and groups:

rm -fv /etc/dbus-1/system.d/pulseaudio-system.conf

Command Explanations

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

-Dbluez5=disabled: This switch prevents a runtime error if dbus-1.14.6 and SBC-2.0 are both installed but BlueZ-5.66 is not installed. Remove this if you have installed all three packages.

-Ddoxygen=false: This allows the package to compile if Doxygen-1.9.6 is not installed. Remove this if you have installed this and wish to build the documentation.

Configuring PulseAudio

Config Files

There are system wide configuration files: /etc/pulse/daemon.conf, /etc/pulse/client.conf, /etc/pulse/default.pa, and user configuration files with the same names in ~/.config/pulse. User configuration files take precedence over system wide ones.

Configuration Information

You may have to configure the audio system. You can start pulseaudio in command line mode using pulseaudio -C and then list various information and change settings. See man pulse-cli-syntax.

If pulseaudio was working but you no-longer have sound, after checking for hardware issues (speakers or headphones not connected, external amplifier not connected) you may need to fix it.

One suggestion is to close the application, such as firefox where sound has stopped working, then run: pactl list short sinks followed by: pacmd set-default-sink <sink #> and then restart the application.

If that does not work, a more drastic approach often works. After closing the application, close pulseaudio, either using pulseaudio –kill or, if that fails, killall -KILL pulseaudio and then rm -rf ~/.config/pulse/* (and perhaps also rm -rf ~/.pulse/* if you have used a very old version of pulse on this machine), then run pulseaudio –verbose to restart it. If the daemon starts, restart the application. See man pulseaudio for more options.

User Notes: https://wiki.linuxfromscratch.org/blfs/wiki/xine-lib

Installation of Xine Libraries

First, fix building this package with binutils-2.39:

sed -e '/xine_set_flags/s/XINE_PROTECTED//' -i include/xine.h

Install Xine Libraries by running the following commands:

./configure --prefix=/usr          \
            --disable-vcd          \
            --with-external-dvdnav \
            --docdir=/usr/share/doc/xine-lib-1.2.13 &&
make

To create the API documentation, Doxygen must be installed and issue the following command:

doxygen doc/Doxyfile

This package does not come with a test suite.

Now, as the root user:

make install

Note

When installing, the Makefile does some additional linking. If you do not have Xorg in /usr, the LIBRARY_PATH variable needs to be defined for the root user. If using sudo to assume root, use the -E option to pass your current environment variables for the install process.

If you built the API documentation, issue the following commands as the root user to install it:

install -v -m755 -d /usr/share/doc/xine-lib-1.2.13/api &&
install -v -m644    doc/api/* \
                    /usr/share/doc/xine-lib-1.2.13/api

Command Explanations

--disable-vcd: This switch is required to compile Xine Lib without VCDImager installed. Remove this option if you have installed VCDImager.

--with-external-dvdnav: This switch is required, because internal libraries cannot decrypt DVD.

--docdir=/usr/share/doc/xine-lib-1.2.13: This switch causes the documentation to be installed into a versioned directory instead of the default /usr/share/doc/xine-lib.

--disable-vaapi: use this switch if libva-2.17.0 is installed and GLU-9.0.2 is not, to prevent a build failure.

Contents
