.. _t-no-media:

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 :ref:`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) <http://www.cccp-project.net/>`_.  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 <http://dynamic.telestream.net/downloads/download-flip4macwmv.htm>`_.

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 <https://help.ubuntu.com/community/RestrictedFormats/>`_.

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 <https://wiki.archlinux.org/index.php/Codecs>`_.

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 <http://rpmfusion.org>`_ 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 <http://www.linuxjournal.com/video/getting-mp3-support-fedora-using-rpmfusion-repositories>`_
to enable extra audio and video formats on Fedora

.. _t-no-media-items:

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 :menuselection:`Settings --> Plugins` or
press :kbd:`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.

.. image:: pics/plugin_list_main.png

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 :ref:`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
<http://www.microsoft.com/downloads/en/details.aspx?FamilyID=048dc840-14e1-467d-8dca-19d2a8fd7485&displaylang=en>`_.

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

Installing the `Visual C++ Runtime Redistributable. <http://www.microsoft.com/downloads/en/details.aspx?FamilyID=9b2da534-3e03-4391-8a4d-074b9f2bc1bf&displaylang=en>`_
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 :ref:`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 :ref:`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 
:guilabel:`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 :ref:`xfce4display`
for a solution.
