Description Bruno Pitrus 2024-01-31 15:41:13 UTC 
When i installed phonon4qt5-backend-vlc to replace the obsolescent gstreamer backend, dragon player would play no videos. In the console the following messages would show repeatedly:

Further testing shows that installing the `vlc` package additionally (containing the VLC gui application) resolves the problem. The problem reappears after removing just `vlc`, suggesting that a needed library is contained in that very package.

Of course, a system library depending on an application with a .desktop file is unacceptable — we are not Arch. Please fix this packaging issue.

Hm, sounds like /usr/lib64/vlc/plugins/video_output/ needs to be split out then?
Comment 2 Bruno Pitrus 2024-02-28 12:25:27 UTC 
phonon-vlc-qt6 still has this problem. This is made worse because there is no longer the gstreamer backend.

the package is split into what has a dep on X and what does not (at least in theory - sometimes errors creep in)

vlc being the 'main' package will keep the desktop file of course.

so we would need to split away:

/usr/lib64/vlc/libvlc_pulse.so
/usr/lib64/vlc/libvlc_pulse.so.0
/usr/lib64/vlc/libvlc_pulse.so.0.0.0
/usr/lib64/vlc/libvlc_xcb_events.so
/usr/lib64/vlc/libvlc_xcb_events.so.0
/usr/lib64/vlc/libvlc_xcb_events.so.0.0.0
/usr/lib64/vlc/plugins/access/libavio_plugin.so
/usr/lib64/vlc/plugins/access/libpulsesrc_plugin.so
/usr/lib64/vlc/plugins/access/libxcb_screen_plugin.so
/usr/lib64/vlc/plugins/audio_output/libpulse_plugin.so
/usr/lib64/vlc/plugins/codec/libavcodec_plugin.so
/usr/lib64/vlc/plugins/codec/liblibass_plugin.so
/usr/lib64/vlc/plugins/control/libxcb_hotkeys_plugin.so
/usr/lib64/vlc/plugins/demux/libavformat_plugin.so
/usr/lib64/vlc/plugins/notify/libnotify_plugin.so
/usr/lib64/vlc/plugins/packetizer/libpacketizer_av1_plugin.so
/usr/lib64/vlc/plugins/packetizer/libpacketizer_avparser_plugin.so
/usr/lib64/vlc/plugins/services_discovery/libpulselist_plugin.so
/usr/lib64/vlc/plugins/services_discovery/libxcb_apps_plugin.so
/usr/lib64/vlc/plugins/stream_out/libstream_out_chromaprint_plugin.so
/usr/lib64/vlc/plugins/text_renderer/libfreetype_plugin.so
/usr/lib64/vlc/plugins/text_renderer/libsvg_plugin.so
/usr/lib64/vlc/plugins/video_chroma/libswscale_plugin.so
/usr/lib64/vlc/plugins/video_output/libaa_plugin.so
/usr/lib64/vlc/plugins/video_output/libcaca_plugin.so
/usr/lib64/vlc/plugins/video_output/libegl_wl_plugin.so
/usr/lib64/vlc/plugins/video_output/libegl_x11_plugin.so
/usr/lib64/vlc/plugins/video_output/libglconv_vaapi_wl_plugin.so
/usr/lib64/vlc/plugins/video_output/libglx_plugin.so
/usr/lib64/vlc/plugins/video_output/libxcb_window_plugin.so
/usr/lib64/vlc/plugins/video_output/libxcb_x11_plugin.so
/usr/lib64/vlc/plugins/video_output/libxcb_xv_plugin.so
/usr/lib64/vlc/plugins/video_splitter/libpanoramix_plugin.so
/usr/lib64/vlc/plugins/visualization/libglspectrum_plugin.so
/usr/lib64/vlc/plugins/visualization/libprojectm_plugin.so

Those would all be thing an external consumer of libVLC would need access to (meaning there would basically be nothing nothing left in the vlc package than desktop files, icons and metadata - plus some kde4 integration stuff (?))

The VLC backend will require both vlc and vlc-noX for the moment.

If that really causes harm in the future, we can revisit the topic.

=> considering fixed (splitting further seems overkill)
