For building VLC from slackbuilds.org you have to build about 45 dependencies. Several dependencies fail to build.

Libavc1394, libdirac, schroedinger, Orbit2, libdaemon and zvbi
==============================================================
The error is:
checking build system type... Invalid configuration `aarch64-slackware-linux': machine `aarch64-slackware' not recognized
configure: error: /bin/sh .auto/config.sub aarch64-slackware-linux failed

I "solved" this by changing the configure part of the Slackbuild
"--build=$ARCH-slackware-linux" into "--build=arm-slackware-linux"
Probably this is not the way to do it, but in this way I was able to build the package.

Chromaprint
===========
For chromaprint I used https://github.com/Ponce/slackbuilds...es/chromaprint

Libmpeg2
========
After "fixing" the "error: /bin/sh .auto/config.sub aarch64-slackware-linux failed" I got:
motion_comp_arm_s.S: Assembler messages:
motion_comp_arm_s.S:1: Error: junk at end of line, first unrecognized character is `@'

x265
====
CMake Error: The source directory "/tmp/SBo/x265_3.6/source" does not exist

musepack-tools
==============
Make Generate step failed. Build files cannot be regenerated correctly.

libbonobo
=========
After "fixing" the "error: /bin/sh .auto/config.sub aarch64-slackware-linux failed" and building :OORBit2-2.14.19 I got
configure: error: Package requirements ( ORBit-2.0 >= 2.11.2 ORBit-CosNaming-2.0 >= 2.11.2 gmodule-2.0 >= 2.0.1 glib-2.0 >= 2.25.7 gobject-2.0 >= 2.25.7 gthread-2.0 >= 2.25.7 gio-2.0 >= 2.25.7) were not met:

libsidplay2
===========
After "fixing" the "error: /bin/sh .auto/config.sub aarch64-slackware-linux failed" I got:
xsid.cpp:99:5: error: narrowing conversion of ''\200'' from 'char' to 'int8_t' {aka 'signed char'} [-Wnarrowing]

Any suggestions are welcome.

I found you should use "--built=$ARCH-unknown-linux", see https://www.linuxquestions.org/quest...est+Threads%29

Libmpeg2 compiles fine now.

Libsidplay2 compiles fine after patching, see https://mailman.videolan.org/piperma...ry/130349.html

X265 compiles by changing "-DCMAKE_BUILD_TYPE=Release ../source" into "-DCMAKE_BUILD_TYPE=Release ../x265_3.6/source", but fails building the package:

-- Installing: /tmp/SBo/package-x265/usr/bin/x265
-- Set non-toolchain portion of runtime path of "/tmp/SBo/package-x265/usr/bin/x265" to ""
cp: cannot stat 'COPYING': No such file or directory
cp: cannot stat 'doc/intra/*': No such file or director

=> to build the package comment out in x265.Slackbuild:
cp -a COPYING doc/intra/* $PKG/usr/doc/$PRGNAM-$VERSION
cat $CWD/$PRGNAM.SlackBuild > $PKG/usr/doc/$PRGNAM-$VERSION/$PRGNAM.SlackBuild

Musepack-tools: builds fine (I had overlooked two dependencies).

It also complains about, despite ORBit2 has been installed:
No package 'ORBit-2.0' found
No package 'ORBit-CosNaming-2.0' found


Anybody has tried to build libbonobo?

try it vlc or package vlc-3.0.17.4-aarch64-1mara.txz

Because I did not know libbonobo was a necessary dependency and it is deprecated (https://developer-old.gnome.org/libbonobo/), I skipped it. I also skipped avahi.

For Raspberry Pi I added to the configure part of vlc.Slackbuild:
--disable-mmal \
--enable-gles2 \

After installing I can play audio with video from disk.

Opening a network stream (IPTV) fails:
[00007fff28008380] http stream error: local stream 1 error: Cancellation (0x8)
[00007fff2814ebd0] adaptive demux: Changing stream format Unknown -> TS
[00007fff2814ebd0] adaptive demux error: Failed to create demuxer (nil) TS

Only the last one of my m3u8 playlist gives audio (no video):
[00007fff2818d2d0] adaptive demux: Changing stream format Unknown -> Packed AAC
[00007fff14355700] mpeg4audio demux packetizer: AAC channels: 2 samplerate: 48000

[00007fff28312a70] main decoder error: buffer deadlock prevented

[00007fff2818d2d0] http demux error: peer stream 5 error: Cancellation (0x8)

Using an USB DVB-T2 stick fails: "Your input can't be opened". Also not by using tvheadend.

On Raspberry Pi OS Bookworm VLC does not show these failures.

Summarized: finally I was able to build VLC, can play audio and video files, but not IPTV or DVB-T2.

What could I do to fix this?

Thanks for providing a package. I have tested it:

Playing mp4 file
================
[00007fff107e5220] main filter error: Failed to create video converter
Segmentation fault

For IPTV no sound or video
==========================
Codec not supported:
VLC could not decode the format "mp4a" (MPEG AAC Audio)

DVB-T2
======
Your input can't be opened:
VLC is unable to open the MRL 'dvb-t2://frequency=482000000'. Check the log for details.

Unfortunately this build seems not to be better for me.

I've been using VLC-3.0.20 successfully on the Pi-400 for some time now, basically using the SBo build. I don't have every single dependency installed, only the ones necessary for my specific requirements (mpeg-2, x254, x265, etc). VLC seems to build fine like that as it appears to ignore things that aren't there unless they are absolutely essential.

The one thing I did find is that it was very unhappy using the default OpenGL video output. I ended up moving /usr/lib64/vlc/plugins/video_output/libgl_plugin.so and libgl_plugin.la out of harms way. Since then it has worked flawlessly! It obviously doesn't like something about the OpenGL distributed with Slackware...!

Strangely, I can't get 3.0.20 to work on x86_64, though 3.0.19 works just fine!

The docs or ldd is your friend. They've probably bumped a few library versions.

Yes, but it was a fresh compile on my system, and didn't complain when compiling! I should have added that the 3.0.19 I'm running is AlienBob's.

And Slackwareaarch64 has the same versions of everything else!
