Do you still see a similar problem with the Debian 12 stable release?

I was unable to reproduce this issue in a relatively minimal virtual
machine, after running:

apt install xorg xdm openbox
apt install --no-install-recommends totem

and then rebooting, logging in at the xdm prompt and running totem from
an xterm.

If I additionally install gstreamer1.0-tools, I can see gtkglsink and
glsinkbin listed in the output of `gst-inspect-1.0`.

`gst-inspect-1.0 gtkglsink` says the filename of the plugin for gtkglsink
is /lib/x86_64-linux-gnu/gstreamer-1.0/libgstgtk.so, which is the same file
as /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstgtk.so.
`dpkg -S /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstgtk.so` says that
is in the gstreamer1.0-gtk3 package.

Similarly, glsinkbin is part of the gstreamer1.0-gl package.

totem has hard dependencies on both gstreamer1.0-gl and gstreamer1.0-gtk3,
and the dpkg output in your bug report said you have both of those packages
installed.

Do you perhaps have a local copy of the GStreamer libraries in /usr/local
or ~/.local or some similar location, that could be interfering with
detection of the plugins provided by Debian?
