vlc was built with the options OPENCV=yes WAYLAND=yes

I admit that I don't test that particular option combination very
often.
I just rebuilt vlc with OPENCV=yes (using opencv-legacy) and a quick
test of the resulting vlc was fine.
However the wayland option is quite time consuming to test since it
requires qt5 to have been (re)built with wayland, wayland-egl &
wayland-protocols already installed. It's now late enough here that it
will be an overnight job to rebuild qt5 and then vlc.
In the meantime, could you build & test vlc without wayland support?
Success there would indicate that wayland support is the problem. Then
we'd have to figure out a possible fix or just not support that option
any more.

I've now also tried the other way around, enable wayland and disable
opencv (legacy) and it now runs without seg-faulting, which is the
opposite result of your test!. I'm open to more suggestions,
although at
least it runs now,
I finished building wayland enabled (but otherwise standard) qt5 and vlc
in a stock 14.2 x86_64 VM with opencv-legacy. It runs normally - no
segfault and I can play a test video with it.
When run it from a terminal, the only new output is:
libEGL warning: DRI2: failed to authenticate
but it has no apparent effect to the running vlc.
Since you're segfault-free after removing opencv-legacy, I guess that's
the place to look for a cause - perhaps some exotic option it's built
with?
(looking at opencv-legacy, I built it will all options, including
ffmpeg which is a recursive dependency via frie0r)

Although without opencv , vlc starts up ok, when I try to play an mp4
video file i get
codec not supported
VLC could not decode the format "h264" (H264 -MPEG-4 AVC (part 10))
despite the fact that vlc and ffmpeg have been compiled with everything
(all required and optional dependencies) except libva and
libva-intel-driver
(as I use amd apu's.)
any ideas?
I think I already commented/replied at least once in recent weeks/months
that vlc hasn't worked for me for over a year. I get similar errors
trying to play any sort of video, and it won't compile anymore either.
I know with some SlackBuilds (such as GNUtella) the flags, that SBo
administrators have decided should be in every build (fpic, etc.) break
the SlackBuild. What about trying it without some of these so-called
'required'/default flags? I don't have much hope for vlc because
actually it's also totally broken when I try to play any video on some
other GNU/Linux OS distributions that may have official packages...
