For months now, I've ran into a block with opencascade, vlc, pipewire and several other video packages. I have to emerge -C vlc and opencascade to do emerges on video stuff then re-emerge them when done. I don't know if it is me or something else but it has been that way for months. I posted a thread about it a few months back. I dunno. I'm working on the change now. ;-) And mplayer just failed with this nifty message.

Unless you create your own sddm config file in /etc, the sddm package uses a
default config file. From the man page:
FILES
/usr/share/sddm/sddm.conf.d
System configuration directory
/etc/sddm.conf.d
Local configuration directory
/etc/sddm.conf
Local configuration file for compatibility
/usr/share/sddm/themes
Where sddm looks for themes
Search in the above paths and you should find the default sddm config file,
which you can copy over to /etc and tweak it to stop it recording events in
your user xsession log file.

I would think it uses ffmpeg to decompress, parse, decode and play a file when
previewed in dolphin.

I understand these video players use ffmpeg libraries too.

Yes:
~ $ lsof | grep ffmpeg
kioslave5 8826 michael mem REG 0,19
435168 /usr/lib64/qt5/plugins/kf5/thumbcreator/ffmpegthumbs.so (path dev=0,23)
Dolpin would not need a video player's functionality just to preview a
thumbnail of a video file.
