Issue Report: DBus cannot connect to the OMXPlayer process

Issue Report

Description

I can't run the basic examples included in the documentation, I get the "SystemError: DBus cannot connect to the OMXPlayer process". I can see this is a historical issue but I can't find any way to resolve it. I have followed the installation as described in docs - I'm using Python 3 so I used pip3 install etc. Also tried in Python 2 with no luck.

Problem reproduction

from omxplayer.player import OMXPlayer
from pathlib import Path
from time import sleep

FILE = '../testmedia/test0.mp4'

player = OMXPlayer(FILE) # no difference with argument dbus_name='org.mpris.MediaPlayer2.omxplayer0'

sleep(5)

player.quit()

For me missing permissions on the /tmp folder caused this issue. Something on raspbian must have changed, because in the past it never was a problem.

A quick fix was adding this to /etc/rc.local sudo chmod 1777 /tmp

Omxplayer has changed in stretch? it is now a fork based on this repository.

omxplayer - Commandline multimedia player for the Raspberry Pi Build date: Wed, 05 Jul 2017 16:40:39 +0100 Version : 5a25a57 [debian] Repository: git@github.com:XECDesign/omxplayer.git https://github.com/XECDesign/omxplayer/commit/5a25a579a81a585c5166cd4896e8e8a56180d6e8

I am trying to find out what has changed

I was surprised to find out about this XECDesign release.

Apparently the official omxplayer release comes no longer from the popcornmix repository but from the XECDesign repository branch debian.

I also got this error message when I ran my own script. I figured out the problem was, that I wasn't using pathlib.

After changing this

from omxplayer.player import OMXPlayer

path = 'path/to/file'
player = OMXPlayer(path)

to this

from omxplayer.player import OMXPlayer
from pathlib import Path

path = Path('path/to/file')
player = OMXPlayer(path)

the error doesn't occur anymore for me. I see that this is the same for @AidanTek.

The response by @johannesvogel is correct. You'll need to pass in a Path object, I'll fix this in https://github.com/willprice/python-omxplayer-wrapper/issues/149 so you can also pass in a string.

Thanks for contributing - I was able to get the DBus error to cease - However, I have to remove all arguments to achieve a video playing successfully.

Is there an exception to adding arguments using this method? I am attemping to utilize '--loop' and some window/aspect arguments as well through hdmi.

I'm utilizing @JonnyAlpha 's method, and once I get the looping video, I will be utilizing GPIO Pull Down/Up to initiate a 2nd video to play, and upon the 2nd videos completion - Start the Looping video again.

I'm using Any input is greatly appreciated.
