incorect end of omxplayer and problem with dbus "Failed to connect to socket"

[miklik72]

Hi,

I'm creating simple video toy with RPI zero w. I use three buttons (GPIO) to control omxplayer (rew,ff,pause). I'm starting omxplayer via omxplayer-wraper from Python script as systemd service. When I'm killing filmstop.py script or omxplayer process as crash simulation, next time I cannot control omxplayer by dbus. This writing message "dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoServer: Failed to connect to socket /tmp/dbus-jxwpK9IGAt: Connection refused". Then when I'm stopping py script by ctrl+c and starting it again I can control player via dbus again. Is any possibility to check or reinitialize dbus before start omxplayer?

Same issue here. It doesn't seem to be very deterministic, sometimes after some media termination the DBus connection just gets broken and no further DBus requests are possible until it's restarted.

--EDIT--

Wow, I didn't notice that this issue was posted more than 2 years ago and yet got no answer.
