WARNING: dbus connection could not be established #36

Closed Francesc116 closed 8 years ago

Francesc116 commented 8 years ago

Hello,

I want to synchronise two raspberry pi 2 with omxplayer-sync, but I have no success for the moment. Even, playing the synctest.mp4 video in 1 raspberry I get the warning

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

I reinstalled everything (raspbian from NOOBS) following this tutorial

https://www.uni-weimar.de/medien/wiki/Automation/RaspberryPi

The video plays, but I always get this warning. I guess that's the reason the sync doesn't work when I try with 2 raspberry.

I would appreciate any help!

PS: I saw someone had a similar problem https://github.com/turingmachine/omxplayer-sync/issues/22, but I can't fix deleting the /temp dir, etc.

Francesc116 commented 8 years ago

I'm using the user "pi" all the time, both for installing and playing the video.

Francesc116 commented 8 years ago

I reinstall everything again with root. Same problem.

  1. // I install raspbian from NOOBS
  2. // I update the OS sudo su sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade sudo apt-get install raspberrypi-net-mods
  3. // I update the "Fimware" sudo apt-get install git wget https://raw.github.com/Hexxeh/rpi-update/master/rpi-update -O /usr/bin/rpi-update && sudo chmod +x /usr/bin/rpi-update sudo rpi-update
  4. // reboot sudo reboot
  5. // I install pexpect sudo su sudo apt-get install python-pexpect
  6. // I install python bindings for DBUS (I create the dir "pydbus-master" in "/home/pi". I guess that can't be the problem). sudo apt-get install python3-setuptools sudo cd /home/pi 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
  7. // Finally I install omxplayer-sync from yokto.net 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
  8. I download the test video and put it in a empty dir sudo cd /home/pi/Videos sudo wget https://github.com/turingmachine/omxplayer-sync/raw/master/synctest.mp4
  9. // reboot again sudo reboot
  10. // I play the video (just to try it works fine, before starting with the synchronisation) sudo su sudo omxplayer-sync -mbv synctest.mp4

The video plays, but I get the message:

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

I guess, this is the reason it doesn't work when I try to sync 2 raspberry later.

I'm desperate!! :)

Francesc116 commented 8 years ago

No one..? Really, anyone is using this software with Raspbian Jessie? It doesn't work at all.

turingmachine commented 8 years ago

In step 6 you install python bindings by source. You should install the python bindings with apt-get:

sudo apt-get install python-dbus
Francesc116 commented 8 years ago

Thanks for your answer turingmachine. I tried that, but with any success. I have made a new fresh installation, and it seems python-dbus is installed before arriving to the step 6. I think there is something wrong with the Raspbian Jessie version.

In details:

1.- // I install a fresh Raspbian from NOOBS_v1_5_0. So, the version is Raspbian Jessie. // I configure the wifi in my Raspberry, in order to donwload all the packages

2.- // I update the OS $ sudo su $ sudo apt-get update $ sudo apt-get upgrade $ sudo apt-get dist-upgrade $ sudo apt-get install raspberrypi-net-mods

3.- // I update the "Fimware" $ sudo apt-get install git $ wget https://raw.github.com/Hexxeh/rpi-update/master/rpi-update -O /usr/bin/rpi-update && sudo chmod +x /usr/bin/rpi-update $ sudo rpi-update

4.- // reboot $ sudo reboot

5.- // I install pexpect $ sudo su $ sudo apt-get install python-pexpect

6.- // I install python-dbus $ sudo apt-get install python-dbus

---> but It says python-dbus is already the newest version.

7.- // Finally I install omxplayer-sync from yokto.net $ 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

8.- I download the test video and put it in a empty dir $ cd /home/pi/Videos $ sudo wget https://github.com/turingmachine/omxplayer-sync/raw/master/synctest.mp4

9.- // reboot again $ sudo reboot

10.- // I play the video (just to try it works fine, before starting with the synchronisation) $ sudo su $ cd /home/pi/Videos $ sudo omxplayer-sync -mbv synctest.mp4

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

Should I receive this warning? Should the sync works with this warning?

turingmachine commented 8 years ago

Are you able to play a movie with omxplayer directly?

i.e. omxplayer synctest.mp4

Francesc116 commented 8 years ago

Yes, without problems.

omxplayer synctest.mp4 --> works, no WARNINGS

omxplayer-sync -mbv synctest.mp4 --> works, with the dbus WARNING

turingmachine commented 8 years ago

I guess nobody tried this on jessie yet. Can you try with raspbian wheezy?

Francesc116 commented 8 years ago

Yes, with Wheezy works. With Jessie it doesn't.

Thanks!

burtonworldart commented 8 years ago

Francesc116. I followed your lead for Wheezy and have almost got it working. However I get a "WARNING: unable to get current filename from master" from the -luv (slave) Pi. Not sure if this is a dbus issue but I also tried the sudo apt-get install python-dbus. Did you run into or resolve this warning? i tried Step 7 as sudo but had to su to root to get anything to work.

Francesc116 commented 8 years ago

It seems a network problem, or files with different name. There are some solved issues with this error. Almost working? What have you changed? I can test it, my network configuration is fine (in fact, the sync works with Wheezy without issues).

burtonworldart commented 8 years ago

I've updated my /etc/network/interfaces in Nano to the NOOBS default but still no connection to network. I then tried to make the net static and assigned a static IP address for each Pi. Pi1= 192.168.2.1 and Pi2= 192.186.2.2 both with net mask at 255.255.255.0 Both Pis will ping each other so network seems ok but wondering if there's a user permissions to access the network I'm missing?
Any help or thoughts are welcomed.

Francesc116 commented 8 years ago

If you follow the steps it works in Wheezy. In Jeesie, nothing to do. It doesn't work. I configure the wifi at the step 1. Without internet connection, it's not possible to install the packages.

Step 1:

If you do this in all your Raspberry, they will be in the same network. If you have 2 Raspberry using your wifi connection, by default, if you don't touch anything, they are automatically in the same network. Of course, later you can try to assign static IP or not to use the wifi.

I hope it helps.

burtonworldart commented 8 years ago

Thanks, This was helpful to find a better way to setup wifi.

Did you delete the network={.......} in /etc/wpa_supplicant.conf file after setting up omxplayer-sync? Does that matter maybe? Conflict between ethernet and wifi?

I used a fresh version of Wheezy 3.18 but still have "network unreachable" error upon playing omxplayer-sync -mbv syncretist.mp4.

I did solve the dbus error however: //step 7: When I ran as pi user with sudo in front of each line I got your bus error. instead of sudo i front of each line I ran each line from root (sudo su). example: $ sudo su $ apt-get remove omxplayer $ rm -rf /usr/bin/omxplayer /usr/bin/omxplayer.bin /usr/lib/omxplayer Once I reran each line the movies played OK individually.

I haven't deleted it. I'm testing the sync via wifi.

I get the dbus error with Rapsbian Jessie. With Raspbian Wheezie, my steps work perfect to me.

burtonworldart commented 8 years ago

I know you are still testing this on Jessie and I thank you for your time. Looks like Turingmachine is slower to respond. I followed your steps for Wheezy 3.18 exactly. Same filename, same location, calling omxplayer-sync exactly the same (except flags -muv on Pi A and -luv Pi B). Same error.

After error I tried On Pi A

sudo ip ad add 10.0.0.10/24 dev eth0 On Pi B

sudo ip ad add 10.0.0.20/24 dev eth0 To test from A to B

ping 10.0.0.20 To test from B to A

ping 10.0.0.10

100% packet swapping.

What on Earth am I missing? Still running Wheezy 3.18

magdesign commented 8 years ago

I'm running it on Jessie without any issues.

Francesc116 commented 8 years ago

Hi!

Did you install python-dbus ? Yes, I detailed all my steps:

6.- // I install python-dbus $ sudo apt-get install python-dbus ---> but It says python-dbus is already the newest version.

Maybe that's the problem. The python-dbus version.

Is the network cable connected when you boot up yes

omxplayer-sync was never tested to work with wifi. I tried with ethernet too

always use fixed Ip addresses yes

I will try with that version of python-dbus.

Thanks

barlaensdoonn commented 8 years ago

Last time I used omxplayer-sync was on a Wheezy distro, and sync over wifi worked no problem, although ethernet obviously performed better.

Also worth noting is that setting a static IP address in Jessie is slightly different than Wheezy, as per this thread. Seems it is recommended to leave /etc/network/interfaces as is and modify /etc/dhcpcd.conf instead, even if modifying the interfaces file still works in some cases.

magdesign commented 8 years ago

Is this still an issue ?
