Beyond Linux® From Scratch - Version 7.9

Chapter 48. Video Utilities

VLC-2.2.2

Introduction to VLC

VLC is a media player, streamer, and encoder. It can play from many inputs, such as files, network streams, capture devices, desktops, or DVD, SVCD, VCD, and audio CD. It can use most audio and video codecs (MPEG 1/2/4, H264, VC-1, DivX, WMV, Vorbis, AC3, AAC, etc.), and it can also convert to different formats and/or send streams through the network.

This package is known to build and work properly using an LFS-7.9 platform.

Installation of VLC

If both Qt4 and Qt5 are installed, Qt5 has to be hidden from PKG_CONFIG_PATH, due to a bug. Temporarily do it, issuing: 

SAVEPATH=$PKG_CONFIG_PATH &&
PKG_CONFIG_PATH="\
`echo $PKG_CONFIG_PATH | sed 's@:/opt/qt5/lib/pkgconfig@@'`"

If you wish to avoid thousands of annoying warnings, issue: 

sed -i 's/ifndef __FAST_MATH__/if 0/g' configure.ac

Install VLC by running the following commands: 

sed -e 's:libsmbclient.h:samba-4.0/&:' \
    -i modules/access/smb.c &&

sed -e '/LUA_C/ i #define LUA_COMPAT_APIINTCASTS' \
    -i modules/lua/vlc.h    &&

sed -e '/core.h/ {
        a #include <opencv2/imgproc/imgproc_c.h>
        a #include <opencv2/imgproc/imgproc.hpp>
    }' \
    -i modules/video_filter/opencv_example.cpp &&

./bootstrap &&

OPENCV_LIBS="-L/usr/share/OpenCV" \
./configure --prefix=/usr &&

sed -e '/seems to be moved/s/^/#/' \
    -i autotools/ltmain.sh libtool &&

In order to build with Lua 5.1 compatiblity, issue: 

CFLAGS='-fPIC -O2 -Wall -Wextra -DLUA_COMPAT_5_1' make

Again, if both Qt4 and 5 are installed, restore PKG_CONFIG_PATH: 

PKG_CONFIG_PATH=$SAVEPATH &&
unset SAVEPATH

To test the results, issue: make -k check. Tests must be run from an active X session. One test fails for unknown reasons.

Now, as the root user:

[Note]

Note

If the XORG_PREFIX is not /usr, make sure the LIBRARY_PATH environment variable is set properly when doing the install, For example: sudo make LIBRARY_PATH=$XORG_PREFIX/lib ... install. 

make docdir=/usr/share/doc/vlc-2.2.2 install
[Note]

Note

This package installs icon files into the /usr/share/icons/hicolor hierarchy and desktop files into the /usr/share/applications hierarchy. You can improve system performance and memory usage by updating /usr/share/icons/hicolor/index.theme and /usr/share/applications/mimeinfo.cache. To perform the update you must have GTK+-2.24.29 or GTK+-3.18.7 installed (for the icon cache) and desktop-file-utils-0.22 (for the desktop cache) and issue the following commands as the root user: 

gtk-update-icon-cache &&
update-desktop-database

Command Explanations

sed -i ...: This sed fixes compilation with Samba 4.

sed -e ... -i modules/lua/vlc.h This sed fixes compilation with lua 5.3.

sed -e ... -i modules/video_filter/opencv_example.cpp This sed partially fixes compilation with OpenCV 3.

OPENCV_LIBS="-L/usr/share/OpenCV" This environment variable helps the linker to find libippicv.a installed by OpenCV 3.

./bootstrap: This command calls autoreconf to generate m4 macros and prepare Makefiles.

sed -e ... -i.orig autotools/ltmain.sh libtool: This optional sed removes a lot of invalid build warnings. If desired, remove it.

--enable-opencv=no: This switch disables OpenCV suport.

--disable-lua: Use this switch if you don't have Lua installed.

--disable-mad: Use this switch if you don't have libmad installed.

--disable-avcodec --disable-swscale: Use these switches if you don't have FFmpeg installed.

--disable-a52: Use this switch if you don't have liba52 installed.

--disable-xcb: Use this switch if you don't have X Window System installed.

--disable-alsa: Use this switch if you don't have ALSA installed.

--disable-libgcrypt: Use this switch if you don't have libgcrypt installed.
