--- Comment #13 from Henrik Fehlauer <rk...@lab12.net> --- Thanks for the continued investigation, Duncan, that's really helpful. Awesome solution, I'll create a Diff on Phabricator tonight. Could you try one more thing, so we know a bit better whether the problem is a real fix or more of a workaround for another problem? As you have plenty of time on a slow/broken startup, please attach GDB to the process, interrupt execution and get a backtrace: $ gdb gwenview |& tee backtrace.log $ r - press Ctrl-C while Gwenview is stuck (but after loading debug symbols finished) $ thread apply all bt - attach the backtrace to the bug ---- As for your patches, both are basically reverting the whole feature: - First patch: You don't set HAVE_QTDBUS in CMakeLists.txt anymore, so the rest of the MPRIS integration won't even get compiled. - Second patch: You skip creating Mpris2Service, which would otherwise be the main entry point for everything else of the MPRIS integration. ---- Regarding MPRIS: That's a DBus service provided by Gwenview (org.mpris.MediaPlayer2.Gwenview), which other parts of the infrastructure can call into because it uses a standardized interface (org.mpris.MediaPlayer2). IOW it isn't a separate dependency to install. For example Plasma's mediaplayer applet can list all services providing that interface and call the forward/play/pause methods. Same thing for KDE Connect. I think even with the patch we should investigate why your media keys are not working: - Can you see Gwenview's DBus service in "qdbusviewer"? - Can you change to the next picture with "dbus-send --session --dest=org.mpris.MediaPlayer2.Gwenview --type=method_call /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Next"? - Can you see other services in "qdbusviewer" implementing the interface, e.g. when running VLC? - Can you control VLC with Plasma's mediaplayer applet? - What does your global shortcut configuration in Systemsettings (Media Controller component) look like? -- You are receiving this mail because: You are watching all bug changes.
