Troubleshooting

I can not play videos or other media

If you can not play video or audio through OpenLP, the problem is most likely that the media players have not be properly configured. The recommended media player for OpenLP is VLC, see the manual for config_players for how to setup VLC as your default player.

If you want to use the Phonon player, but it cannot play your media files, you can look below for how best to set it up.

Codecs

You may need to install codecs for certain files to play. Most newer versions of Windows and OS X will support most media types. Most Linux distributions will require a little more help to get certain media types to play.

Microsoft Windows

Later versions of Microsoft Windows (Vista, Windows 7) generally come with everything you need to play most media formats. If for some reason you need additional codecs we have seen success from the Combined Community Codec Pack (CCCP). You might also wish to check out the K-Lite Codec Pack. If you are having issues, results do seem to vary with the different options. What works for some may not for others, so some trial and error may be required.

Mac

If you are using a Mac. You may wish to play Windows formats. flip4mac enables you to use popular Windows formats such as .wmv on your Mac. You can get it from here.

Ubuntu Linux (and variants)

If you are using Ubuntu Linux, or one of its variants (Kubuntu, Edubuntu, etc...) it is a fairly quick and easy process to get all the codecs you need to make things work. You will need to install two meta-packages that contain all the multimedia codecs that you will generally need. From the Software Center install ubuntu-restricted-extras and Kubuntu-restricted-extras, or from the terminal:

user@linux:~ $ sudo apt-get install ubuntu-restricted-extras kubuntu-restricted-extras

Note if you are running Kubuntu there is no need to install the ubuntu-restricted-extras meta-package

For more information on Ubuntu and multimedia issues please check out the community documentation.

Arch Linux

The following command provides the most complete solution for codecs on Arch Linux:

root@linux:~ # pacman -S gstreamer0.10-{base,good,bad,ugly}-plugins gstreamer0.10-ffmpeg

If you need more help with Arch Linux and multimedia please see the Arch Linux documentation.

Debian Linux

You will need to add the Debian Multimedia Repository. So add the folowing to /etc/apt/sources.list:

deb http://www.debian-multimedia.org testing main non-free

Then update the repository info:

root@linux:~ # apt-get update

Then install the following packages:

root@linux:~ # apt-get install gstreamer0.10-ffmpeg gstreamer0.10-lame gstreamer0.10-plugins-really-bad gstreamer0.10-plugins-bad gstreamer0.10-plugins-ugly gstreamer0.10-plugins-good gstreamer0.10-x264

Fedora Linux

You will need to set up Fedora to play most media formats. This is accomplished using the rpmfusion repository.

Note the following commands will enable a third party repository to your system. Please check out the RPM Fusion site for more information.

To enable both the free and nonfree components for any Fedora official release enter the following commands:

su -c 'yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm'

After enabling the rpmfusion repository you will want to refresh your package list, perform any updates and search for gstreamer-good, bad, and ugly and install.

Follow the tutorial using the rpmfusion repository to enable extra audio and video formats on Fedora

The Media Manager appears to be missing some features

If you do not see all the features listed in the Media Manager, you may need to enable them.

To enable the plugins navigate to Settings --> Plugins or press Alt+F7. You will want to click on the plugin to the left that you would like to enable and select active from the drop down box to the right.

By default all plugins should be enabled during the first run wizard except the remotes plugin, unless you specify differently.

I can not see the book, chapter, and verse when I display scripture

The book, chapter, and verse should be displayed when you display scripture. If you can not see this your theme probably has the text size too small for the info to be seen. See the section of the manual on themes if you need more info on text sizes in themes.

I am using PowerPoint 2010 or PowerPoint Viewer 2010 and presentations do not work

Currently OpenLP does not support PowerPoint Viewer 2010. PowerPoint 2010 should work correctly, although some users have reported problems. If you have issues with PowerPoint 2010 or PowerPoint Viewer 2010 try the PowerPoint 2003 or 2007 Viewers. Download the PowerPoint 2007 viewer for free.

I have PowerPoint installed but it does not show as a presentation option

Installing the Visual C++ Runtime Redistributable. has fixed this problem according to some of our users.

I am running a Linux Distro and cannot see the menu icons

This seems to be a problem with XFCE and some versions of Gnome too. To correct this problem, open a terminal and type in the following commands:

gconftool-2 --type boolean --set /desktop/gnome/interface/buttons_have_icons true

gconftool-2 --type boolean --set /desktop/gnome/interface/menus_have_icons true

I chose to use a web Bible but it did not download the entire Bible

Due to copyright restrictions OpenLP cannot download an entire Bible. It can only download the section you search for. If you do not have an internet connection where you intend to use OpenLP you will need another scripture source. For more information about acquiring Bibles please see the section on the import_bibles.

OpenLP is using a large amount of RAM when showing a presentation

OpenLP uses a large amount of RAM when showing a presentation due to the way it handles presentations. OpenLP itself is unable to show those presentations or load the presentation files, so it interacts with the presentation through either Microsoft PowerPoint or LibreOffice Impress. In order to show the slides in the slide controller, OpenLP requests that the presentation application export the slides to images, and then uses those images as slides. This results in a large amount of RAM being used, especially in presentations with more than about 20 slides.

OpenLP is not displaying correctly, or is not on the correct screen

Please read the documentation on dualmonitors. It is very important to have dual monitors setup properly for OpenLP to function as expected.

Previews are slow to load when using a theme with an image background

If you are using a JPG formatted image for your background try converting it to another format. There is a notable performance difference between JPG and a format such as PNG. Other formats work in OpenLP but PNG is the preferred image format and yields the best performance. Images should also be sized to the size of your output. For example, if your output screen is 1024x768 you should size your background image to 1024x768 also. OpenLP does not scale images.

OpenLP crashes on startup on Windows

If Windows is missing a proper driver for the graphics card on the computer, it might cause OpenLP to crash on startup, resulting in a message saying OpenLP has stopped working. To fix this find, download and install the newest driver for your graphics card.

I saved service-files in the servicemanager folder but now they are gone

The servicemanager folder which can be found in OpenLP's data folder is used internally by OpenLP for temporary files and anything in there can and will be deleted by OpenLP. In general you should not modify or create files in OpenLP's data folder unless you know what you are doing.

OpenLP freezes on Xfce4 in a dual monitor setup

There is an issue with the Xfce4 compositor that makes OpenLP freeze when using a dual monitor setup. See configuration of dual monitor for xfce4display for a solution.
