DBUS Error

[turingmachine]

Remove all files in /tmp that got 'omxplayer' in the filename and kill all running dbus instances. Try to restart omxplayer-sync after that. You must only use a single user to start omxplayer or omxplayer-sync respectively. If you did start it once as root and then try to start it as non-root, it will fail.

Still the same issue after cleaning the '/tmp' directory and 'sudo killall dbus-daemon'. will try complete clean install on a fresh raspbian.

ok, I got rid of the error by reinstalling everything from scratch. Here is a little bit more verbose version of the installing instructions:

install pexpect:

sudo apt-get install python-pexpect

install python bindings for DBUS ( https://github.com/LEW21/pydbus ):

sudo apt-get install python3-setuptools
sudo wget https://github.com/LEW21/pydbus/archive/master.zip
sudo unzip master.zip
rm master.zip
cd pydbus-master/
sudo chmod 777 setup.py
sudo ./setup.py build
sudo ./setup.py install

install omxplayer-sync:

sudo apt-get remove omxplayer
sudo rm -rf /usr/bin/omxplayer /usr/bin/omxplayer.bin /usr/lib/omxplayer
sudo wget -O- http://yokto.net/0/omxplayer/omxplayer-3176db4.tar.bz2 | sudo tar -C / -xjvf -
sudo ln -sf /lib/arm-linux-gnueabihf/libpcre.so.3 /lib/arm-linux-gnueabihf/libpcre.so.1
sudo wget -O /usr/bin/omxplayer-sync https://github.com/turingmachine/omxplayer-sync/raw/master/omxplayer-sync
sudo chmod 0755 /usr/bin/omxplayer-sync
sudo wget https://github.com/turingmachine/omxplayer-sync/raw/master/synctest.mp4

Now the same error appeared again. The only thing I changed was the filename and the way the startup script is launched. instead of calling it from /etc/profile i now use .bashrc to call it. I deleted the files in /tmp and restarted and get the same messages.

on the master and server:
WARNING: dbus connection could not be established
org.freedesktop.DBus.Error.ServiceUnknown: The name org.mpris.MediaPlayer2.omxplayer was not provided by any .service files.

when I log in to the x server I get an Error message in a window: GDBus.Error:.org.freedesktop.PolicyKit1.Error.Failed:
Cannot determine user of subject

What is your exact call to omxplayer-sync? Try to start omxplayer directly. What user are you using to play files? omxplayer tries to start it's own dbus server: https://github.com/popcornmix/omxplayer/blob/master/omxplayer#L50

Oh, this is so embarrassing. I was trying to play back an .mpeg. It works well with the .mp4 version of the file. Sorry for the noise. The error message was not exactly helping me to trouble shoot this, but after seing that the test file works well, I realized what's the issue.
