I too expected something similar: stop and play (play for resume)
Have you tried "tree" and "introspect" for org.mpris.kaffeine (not
org.kde.kaffeine)? It works for mpv:
busctl --user call org.mpris.MediaPlayer2.mpv \
/org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player \
Stop
For this we don't need to look here:
"rmmod: ERROR: Module cx23885 is in use" seems enough to see that kernel
module cannot be removed.
I am surprised by it. You have shown that kaffeine closes the device, so
it should be possible to remove the kernel module:
Started with --lastchannel
Video stopped:
lrwx------ 1 valerio valerio 64 9 gen 19.51 6 -> /dev/dri/card0
lrwx------ 1 valerio valerio 64 9 gen 19.51 62 -> /dev/dri/renderD128

lrwx------ 1 valerio valerio 64 9 gen 19.51 9 -> /dev/dri/card0
no more /dev/dvb/, but still unable to remove module cx23885
My hypotheses:
- there are more kaffeine processes (ps xuwf)
- some external process is holding the device, e.g. pulseaudio or
pipeware sound server. Tools that might help to find it: lsof or fuser
(unsure concerning proper options)
- Some other IPC exposed by the driver and used by kaffeine.
- I have not idea if it is possible to create direct connection between
the dvb device and the video card so that data pass without intermediate
interaction with kaffeine.
