A video works on mpv & Chrome but not on VLC

Hi
I'm on Debian testing KDE Wayland, VLC 3.0.21 from the Debian repository.
E.g.
https://www.youtube.com/watch?v=oqZZ2hYD9dQ downloaded via yt-dlp (giving a .webm file) works on mpv & Chrome but not on VLC: sound but black screen.
Thanks.

VLC 3.0 doesn't officially support Wayland. Be sure to use XWayland if you really need that.

There's Xwayland, displayed in System Monitor.
Whether Debian testing KDE Wayland or X11: same.
mpv & Chrome can be both X11 or Wayland (verifiable with xeyes).
By the way why not VLC Wayland?

Qt didn't support Wayland properly at the time when VLC 3.0.0.came out.

Well I failed to build VLC 4
https://wiki.videolan.org/UnixCompile/, with lot of --disable-, otherwise error messages:
Code: Select all
./configure --disable-xcb --disable-qt --disable-nls --disable-avcodec --disable-swscale --disable-dav1d
I finished with:
Code: Select all
make[4]: *** [Makefile:32903: demux/dash/mpd/libvlc_adaptive_la-TemplatedUri.lo] Error 1
I also built VLC 3.0.x with --enable-wayland:
Code: Select all
cd /media/a/01DAC9FBBCD9DE20;git clone --branch 3.0.x https://code.videolan.org/videolan/vlc.git;cd vlc;./bootstrap;cd contrib;mkdir native;cd native;../bootstrap;make;cd /media/a/01DAC9FBBCD9DE20/vlc;./configure --enable-wayland;make
but as
https://wiki.archlinux.org/title/VLC_me ... nd_support it's broke: it's X11 (xeyes follows) & the video still doesn't work.
Will my bug be fixed?

Your problem description is much too vague for anyone to fix it. Besides it seems specific to your setup.

You right: the video works on VLC on Debian stable KDE Wayland live
https://www.debian.org/distrib/.
2 differences: I'm on Debian testing & the official Nvidia beta driver
https://www.nvidia.com/en-us/drivers/, the installer is NVIDIA-Linux-x86_64-565.57.01.run, the live it's NV168 (Nouveau).
A bug of Debian testing so? I wonder why it still works on mpv & Chrome...
What is your distro?
