Build VLC on Slackware 14.0

joenew · 08-25-2016, 02:18 PM

No luck with OSSv4, I had that same version installed yet and it doesn't prevent reported error.

No luck neither with 2.0.10:

Code:

checking mad.h presence... yes
checking for mad.h... yes
checking for mad_bit_init in -lmad... yes
checking if linker supports -Bsymbolic... yes
checking for AVCODEC... yes
configure: error: libavcodec versions 55 and later are not supported yet.

Code:

/var/log/packages/libavc1394-0.5.4-i486-4sl

That should be related to ffmpeg (or libav... I'm not sure if VLC went with one over the other or which you might have installed), not libavc1394 (I believe that's for firewire). It looks like you have a new enough version of ffmpeg, but I believe it is typically patchable without downgrading ffmpeg (see this stack overflow answer for more details).

I suspect my libavcodec is too recent for vlc-2.0.10.
My ffmpeg package (2.8.7) contains following version of libavcodec:

Code:

/usr/include/libavcodec/version.h

Code:

#define LIBAVCODEC_VERSION_MAJOR 56
#define LIBAVCODEC_VERSION_MINOR 60
#define LIBAVCODEC_VERSION_MICRO 100

Now, vlc 2.0.10 sources have a configure.ac with the following check:

Code:

     PKG_CHECK_EXISTS([libavcodec < 56],, [
       AC_MSG_ERROR([libavcodec versions 56 and later are not supported yet.])

That's the problem: I think my libavcodec is too recent to compile that old version of vlc, which requests libavcodec < 56, bu I have version 56.60.100

I tried to make a patch to accept also libavcodec version more recent (I put version 59...):

Code:

--- configure.ac.orig   2016-08-31 19:03:13.127247959 +0200

I also edited Slackbuild to apply it:

Code:

cd $PRGNAM-$VERSION

patch < $CWD/configure.ac.patch || exit 1013
autoconf || exit 1013

chown -R root:root .

The patch works fine, cause the slackbuild starts compiling.
But when it reach building of avcodec plugin it fails with te following errors:

So I think the libavcodec version check in configure was useful: build really fails if libavcodec version is too recent in comparison to libavcodec plugin contained in vlc sources...
What do you think about?

bassmadrigal · 08-31-2016, 08:28 PM

I know some were able to build programs with a new ffmpeg, but it looks like this version of VLC doesn't support that.

Looks like you'd need to downgrade your ffmpeg to 2.3.6 or lower to get libavcodec at 55.

https://www.ffmpeg.org/olddownload.html

joenew · 09-01-2016, 03:30 AM

If you look at original version of config it says:

Code:

   PKG_CHECK_MODULES(AVCODEC,[libavcodec >= 52.25.0 libavutil], [
     PKG_CHECK_EXISTS([libavcodec < 55],, [
       AC_MSG_ERROR([libavcodec versions 55 and later are not supported yet.])

So for vlc 2.0.10 we need (52.25.0 <= libavcodec < 55). If I well understood we have to link vlc to a ffmpeg containing libavcodec 54.x. And I think the last ffmpeg version was:

Code:

FFmpeg 1.2.12 "Magic"
--------------------------
libavutil      52. 18.100
libavcodec     54. 92.100
libavformat    54. 63.104
libavdevice    54.  3.103
libavfilter     3. 42.103
libavresample   1.  1.  0
libswscale      2.  2.100
libswresample   0. 17.102
libpostproc    52.  2.100
--------------------------

Now, I don't want to downgrade my system ffmpeg... There should be a way to statically linking an alternative version of ffmpeg at compile time... I'll looking for that. If you have some suggests.

Oops, good catch. Unfortunately, we're beyond my experience (I've never needed to statically link any dependencies before). But, if you can work your way through Eric's masterful VLC slackbuild, he statically links everything, so people can install just the VLC package and have all dependencies included. I'd imagine you'd need to build ffmpeg, and then point VLC's configure to the new updated binaries. Since you're building an older version of vlc, it might support the --with-ffmpeg-tree configure option. I'd definitely look into that.

joenew · 09-01-2016, 10:24 AM

That's the matter:

Code:

./vlc-2.0.10/configure --help|grep ffmpeg
  --enable-merge-ffmpeg   merge FFmpeg-based plugins (default disabled)

In version 2.0.10 configure flag you suggested is not supported anymore. I had tried it but without success, so I looked at configure options...
I'll look at Eric slackbuild...

joenew · 09-01-2016, 11:29 AM

Ok, Eric slackbuild is a little more complicated...
http://www.slackware.com/~alien/slac...vlc.SlackBuild

The following part is related to vlc compilation

Code:

NCURSES_CFLAGS="$(ncursesw5-config --cflags) -I/usr/include" \
NCURSES_LIBS="$(ncursesw5-config --libs)" \
PROJECTM_LIBS="-lprojectM $VLCDEPSDIR/usr/lib${LIBDIRSUFFIX}/libMilkdropPresetFactory.a $VLCDEPSDIR/usr/lib${LIBDIRSUFFIX}/libRenderer.a -lGLU -lGLEW -lGL" \
PROJECTM2_LIBS="-lprojectM $VLCDEPSDIR/usr/lib${LIBDIRSUFFIX}/libMilkdropPresetFactory.a $VLCDEPSDIR/usr/lib${LIBDIRSUFFIX}/libRenderer.a -lGLU -lGLEW -lGL" \
CPPFLAGS="-I$VLCDEPSDIR/usr/include" \
CFLAGS="-I$VLCDEPSDIR/usr/include $SLKCFLAGS" \
CXXFLAGS="-I$VLCDEPSDIR/usr/include $SLKCFLAGS" \
LDFLAGS="-Wl,-Bsymbolic -L$VLCDEPSDIR/usr/lib${LIBDIRSUFFIX} $SLKLDFLAGS" \
PKG_CONFIG_PATH="$VLCDEPSDIR/usr/lib${LIBDIRSUFFIX}/pkgconfig" \
PATH="$VLCDEPSDIR/usr/bin:$PATH" \
./configure \
...
...

He uses that $VLCDEPSDIR var to say vlc configure where it has to look for right libraries and needed programs like ffmpeg.
Before compile vlc he builds ffmpeg and install it in that directory. Then he recalls it with VLCDEPSDIR var.
I didn't understand if I can use a similar way to compile vlc with static ffmpeg only, while other libraries dynamically linked using the system ones...

bassmadrigal · 09-01-2016, 11:49 AM

He had that flag listed in the deprecated section, but I tried to find how he statically links it now, but I came up short.

After a more in-depth look, it looks like he uses the --prefix=, --libdir=, and --shlibdir= options in ffmpeg to designate where it will install (which he picks a temporary directory under /tmp/tmp-vlc/vlcdeps). Above that, he sets the PKG_CONFIG_PATH variable to that temporary location as well. You can find these lines under the near the ./configure portion for ffmpeg, and you can find ffmpeg's information quickly with a Ctrl+F and searching for "compile ffmpeg".

He then sets a ton of variables when compiling vlc itself, pointing to that vlcdeps directory. The thing I'm not sure on is whether this will work if it doesn't find your other vlc dependencies in there. I'm not sure if it allows you to just statically link ffmpeg without statically linking everything else. Unless Eric pops in with some guidance, it will likely be on you to test that.

However, doing some more digging in the script, it seems like he designed it so if ffmpeg is intended to be linked statically, it will build vpx, theora, amr, amrwbenc, and gsm before it compiles ffmpeg, storing all in that vlcdeps directory. You might be able to use the script if you download that whole directory and replace ffmpeg's source with the 1.1.12 source and the vlc source with your 2.0.10 package, however, many of those dependencies might be new enough that they don't work properly with an older ffmpeg and/or vlc, so using the script might be hit or miss.

I wonder if it is worth devoting all this time towards trying to get a working vlc. Have you tried any other players to see if they use OSSv4 properly? Maybe mplayer (and you could use the smplayer front-end)?

joenew · 09-03-2016, 05:26 AM

Yes I used to paly media with MPlayer. It works fine with OSSv4.
But now I was interested in live streaming ip tv, I found some links working good with VLC (I mean it opens m3u/m3u8 just fine, but with crashes if I use 2.0.3 or audio/video choppiness issues if I use >2.1.x version, as described above... anyway it can open those links to streaming playlists/channels).
MPlayer can't handle those links. So I've tried MPV and it works very good, no issues with ossv4... But mpv alone doesn't show a popup of the playlist... So if you want to change channel on the same palylist you have to "click" forward or press ">" and scroll all channels one by one to reach what you want: it isn't very usable.
I'm using MPV + SMplayer and it is like VLC, It shows all playlist and it has no audio/video playing issues.

My compile tries are now just for "fun"... But begin to waste too time. And likely I'll give up...

I tried to edit Eric slackbuild script. I want to compile statically only what it is needed for compatibility. And use all other libraries form my system.
He split his script code in functions, in each of them he compiles and installs (in $VLCDEPSDIR directory) various libraries and codes like ffmpeg and all other deps, finally he compiles vlc by using that $VLCDEPSDIR as libraries source (through $PKG_CONFIG_PAT as you explained).

The main program would be:

Code:

make_libname1
make_libname2
make_libnameetcetc

make_vlc
build_vlcpkg "$*"

In my test I've simplified his script as follow

Code:

make_ffmpeg
make_dvbpsi
make_vlc
build_vlcpkg "$*"

FFMpeg build is needed for compatibility of libavcodec as we explained in previous messages.
DVBPSI build is needed, cause my system version is too recent.
But It returns an other error:

Code:

checking for libfaad.a in /tmp/vlc-build/tmp-vlc/faad2-... no
configure: error: cannot cd to /tmp/vlc-build/tmp-vlc/faad2-
make: *** Nessun obiettivo specificato e nessun makefile trovato.  Stop.
**

**
make: *** Nessuna regola per generare l'obiettivo «install».  Stop.
find: "/tmp/vlc-build/package-vlc/usr/lib": File o directory non esistente
sed: nessun file in ingresso

faad2 is an "additional lib for vlc" and it is compiled after "ffmpeg".

Code:

    # ffmpeg uses the above static libraries:
    make_ffmpeg
  fi

  # Additional libraries that vlc will use:
  make_faad2
  make_a52
  make_dca
  make_ebml
  make_matroska
  make_libmpeg2
  make_mpcdec
  make_twolame
  #make_daap
  make_upnp
  make_orc
  make_schroedinger
  make_live555
  make_fribidi
  make_taglib
  make_asdcplib
  make_ass
  make_fluid
  make_1394
  make_kate
  make_tiger
  make_lua
  make_bluray
  make_opus

  # Visualisations:
  # FIXME: getting symbol errors but we need a static libGLEW:
  #make_glew
  make_goom
  make_ggi
  make_projectm

  # Digital video:
  make_dv
  make_dvbpsi

  # Speex before shout and vlc:
  make_speex
  make_speexdsp
  make_shout

  #fi # End  ( "xy" == "x" )
fi

if echo "$*" | grep -qw -- --wrapvlcdeps ; then
  # Wrap the vlcdeps tree with all pre-compiled dependencies into a tarball:
  cd $TMP/tmp-$PRGNAM
  find . -name "*.la" -o -name "*.pc" | xargs sed -i -e "s#$TMP/tmp-$PRGNAM#/vlcdepsdir#g"
  tar -jcf $OUTPUT/$PRGNAM-vlcdeps-${SLACKVER}-$ARCH.tar.bz2 \
    vlcdeps \
    a52dec-$A52 \
    faad2-$FAAD2

  echo "Created vlcdeps binary tarball in '$OUTPUT/$PRGNAM-vlcdeps-${SLACKVER}-$ARCH.tar.bz2'..."
  cd -
else
  # Compile VLC using all the precompiled static libs in $VLCDEPSDIR :
  make_vlc

  # Wrap VLC into a Slackware package:
  build_vlcpkg "$*"

Now, may be vlc compile doesn't looks on the system, also if it doesn't find a library in $VLCDEPSDIR... Could be it wants the lib in that dir.
This explains why "configure: error: cannot cd to /tmp/vlc-build/tmp-vlc/faad2-".. While I have "faad2-2.7-i486-2_SBo" installed on my system.

Then read the part where VLC sources are configured and remove this line which makes the VLC build look for a faad2 source directory with compiled libraries in it:

Code:

--with-faad-tree=$TMP/tmp-$PRGNAM/faad2-$FAAD2 \

joenew · 09-06-2016, 11:28 AM

Thanks Eric!

Finally I did it!
There were also some newer enabled flag that I removed from configure...

Anyway, now I've installed this vlc-2.0.10 new package: I tried to run it and open a audio/video file.
Well folks, seems I'm not lucky at all!

VLC automatically selects OSS sound device, but sound is choppy... same as in news version 2.1.x and above.

I started my compiling by edit Eric slackbuild for vlc-2.2, may be that's the matter... perhaps there is some option flag in newer slackbuild that doesn't like to my OSSv4 audio system.

My next try will be to start from Eric slackbuild of vlc-2.0.8 it was under /usr/doc/vlc-2.0.8/*Slackbuild.

Thaks again. I'll let you know.
Bye
