<chapter id="configuration">
<title>Configuring &kplayer;</title>

<para>Like other &kde; programs, &kplayer; is highly configurable. When you
<link linkend="howto-installation">install &kplayer;</link> and its multimedia
playing backend <link linkend="howto-installation-mplayer">&mplayer;</link>,
the default settings should enable your system to play multimedia content
without any additional configuration. This chapter describes ways to make
&kplayer;'s user interface best fit your tastes and configure media playback
for optimal quality and performance.</para>

<sect1 id="configuration-ui">
<title>User interface</title>

<para>When &kplayer; is first installed, its window contains a
<link linkend="parts-menu-bar">menu bar</link>, a
<link linkend="parts-toolbar-main">main toolbar</link>, a
<link linkend="parts-toolbar-playlist">playlist toolbar</link> and a
<link linkend="parts-status-bar">status bar</link>. Additionally, a
<link linkend="parts-toolbar-slider">progress toolbar</link> will usually appear
when you start playing a file.</para>

<para>On the <link linkend="menu-settings"><guimenu>Settings</guimenu>
menu</link> you will find options to hide toolbars that you do not need and to
show <link linkend="parts-toolbar-slider">other available toolbars</link>. Some
of them will only be available for video files, while the progress toolbar is
available when &kplayer; can detect the time length of the current file.</para>

<para>The menu bar itself can be toggled on and off with the shortcut key
combination <keycombo action="simul">&Ctrl;<keycap>M</keycap></keycombo>.
You can also hide the status bar if you do not need the information it
displays.</para>

<para>To show or hide the
<link linkend="parts-library">multimedia library</link>, press
<keycombo action="simul">&Ctrl;<keycap>L</keycap></keycombo> or choose
<menuchoice><guimenu>Settings</guimenu><guimenuitem>Show
Library</guimenuitem></menuchoice>. To show or hide the
<link linkend="parts-message-log">message log</link> detailing internal
operation of &mplayer; backend as well as &kde; <acronym>I/O</acronym> Slaves,
press <keycombo action="simul">&Ctrl;<keycap>G</keycap></keycombo> or choose
<menuchoice><guimenu>Settings</guimenu><guimenuitem>Show
Message Log</guimenuitem></menuchoice>.</para>

<para>Each toolbar has a small area on one of its sides where you can press and
hold the &LMB; to drag the toolbar into a new position. You can place most
toolbars either horizontally at the top or bottom of &kplayer; window or
vertically at the left or right side of it, while the playlist toolbar can only
be positioned horizontally.</para>

<para>Similarly, you can move around the multimedia library and the message log
by pressing and holding the &LMB; on the title area of the window and dragging
it above or below the <link linkend="parts-video-area">video area</link> and
positioning it in relation to the toolbars.</para>

<para>If you <mousebutton>right</mousebutton> click a toolbar, you will get a
<link linkend="popup-toolbar">menu</link> to configure it. You can choose the
toolbar orientation, text position and icon size.</para>

<para>&kplayer; will of course remember all the settings you choose and the
positions where you put your toolbars. It will remember visibility settings
for <link linkend="howto-full-screen">full screen mode</link> and for normal
mode separately.</para>

</sect1>

<sect1 id="configuration-playlist">
<title>Playlist</title>

<para>&kplayer;'s <link linkend="toolbar-playlist">playlist toolbar</link> has
a drop down box that shows the current playlist. It stores files and streams
that have been played or are going to be played and lets you easily switch to a
different item and play it. For details on the playlist feature see the
<link linkend="howto-playlist">Playlist micro-HOWTO</link>.
Following is a description of options that affect the playlist behavior.</para>

<itemizedlist>

<listitem><para><guimenuitem>Loop</guimenuitem> option is available from the
<link linkend="menu-player"><guimenu>Player</guimenu> menu</link>, the
<link linkend="toolbar-playlist">playlist toolbar</link> and the
<link linkend="popup-playlist">playlist popup menu</link>. When enabled, it
makes &kplayer; start playing items from the beginning of the list after it
finishes playing the last item on the list.</para></listitem>

<listitem><para><guimenuitem>Shuffle</guimenuitem> option is also available from
the <link linkend="menu-player"><guimenu>Player</guimenu> menu</link>, the
<link linkend="toolbar-playlist">playlist toolbar</link> and the
<link linkend="popup-playlist">playlist popup menu</link>. When enabled, it
makes &kplayer; play items in a random order. When the
<guimenuitem>Loop</guimenuitem> option is also enabled, items will be reshuffled
every time &kplayer; restarts playback from the top of the list. To reshuffle
immediately, disable the <guimenuitem>Shuffle</guimenuitem> option and then
enable it again.</para></listitem>

<listitem><para><guilabel>Allow duplicate entries on playlists</guilabel> option
is available on the
<link linkend="settings-general"><guilabel>General</guilabel> page</link> of the
&kplayer; Configuration dialog. When enabled, it allows &kplayer; to put
identical entries on the playlist. By default it is disabled, and if you queue
the same file twice, the old entry will be removed before adding the new one at
the bottom of the playlist.</para></listitem>

</itemizedlist>

<para>The <guimenuitem>Edit</guimenuitem> command opens the current playlist in
the <link linkend="parts-library">multimedia library</link> where you can add

configuration</link> for details.</para>

</sect1>

<sect1 id="configuration-library">
<title>Multimedia library</title>

<para>&kplayer;'s <link linkend="parts-library"><interface>multimedia
library</interface></link> is the place to access all your multimedia and
arrange it into playlists. The things you create in the library affect other
parts of &kplayer;, in particular some menus and the current playlist. For
details on the multimedia library feature see the
<link linkend="howto-library">Multimedia library micro-HOWTO</link>.</para>

<sect2 id="configuration-now-playing">
<title>Now Playing</title>

<para>This section shows the contents of the current playlist and lets you
modify it, for example by adding new files, streams and directories, removing
existing items or changing their order. The changes are reflected on the current
playlist shown on the <link linkend="parts-toolbar-playlist">playlist
toolbar</link>. The commands to modify the playlist contents are available from
the <link linkend="menu-library"><guimenu>Library</guimenu> menu</link> or the

<para>The <guilabel>Maximum Recent entries in the library</guilabel> option on
the <link linkend="settings-general"><guilabel>General</guilabel> page</link> of
the &kplayer; Configuration dialog gives the maximum number of files, folders
and streams the <guilabel>Recent</guilabel> section can hold. When a new entry
is added and the total number of entries exceeds this number, the bottom entry
is removed from the list.</para>

<para>The <guilabel>Maximum entries on Play Recent menu</guilabel> option on the
<link linkend="settings-general">same page</link> of the global settings gives
the maximum number of commands the <guisubmenu>Play Recent</guisubmenu> submenus
can have. When a new entry is added and the total number of entries exceeds this
number, the last entry is removed from the menus.</para>

</sect2>

<sect2 id="configuration-playlists">
<title>Playlists</title>

their equivalents on <link linkend="popup-menus">popup menus</link> each have a
list of commands to either play a playlist or add new content to it. Each
playlist in this section has its own command on each of those menus. When you
add, remove or rename a playlist, the menus are updated to reflect the
changes.</para>

<para>The <guilabel>Maximum entries on playlist menus</guilabel> option on the
<link linkend="settings-general"><guilabel>General</guilabel> page</link> of the
&kplayer; Configuration dialog gives the maximum number of playlists that will
be included on the submenus that work on playlists.</para>

</sect2>

<sect2 id="configuration-devices">
<title>Devices</title>

<para>This section lists the disk and tuner devices available on your system
as well as the <acronym>CD</acronym> tracks and <acronym>DVD</acronym> titles
found on the disks you insert into the disk devices and the channels available
on the tuner devices. &kplayer; puts any devices it finds on this list, and you
can add new devices or remove existing ones.</para>

<para>The <link linkend="menu-file"><guimenu>File</guimenu> menu</link> and some
of the <mousebutton>right</mousebutton> click <link linkend="popup-menus">popup
menus</link> have submenus that let you easily access and play multimedia
available on these devices. Each device from this section has its own
<link linkend="submenu-device">submenu</link>. When you add, remove or rename a
device, the menus are updated to reflect the changes.</para>

<para>When &kplayer; finds titles on a <acronym>DVD</acronym> disk or tracks on
a <acronym>CD</acronym> disk, it updates the corresponding menu to include
commands to play the individual titles or tracks. &kplayer; looks for titles and
tracks when you insert a disk into a drive or when you select <guimenuitem>Play
Disk</guimenuitem> or <guimenuitem>Load Disk</guimenuitem> command for a disk
device that does not yet have any titles or tracks listed.</para>

<para>Similarly, when you change the channel list for a tuner device, &kplayer;
updates the corresponding menu to include commands to play each of the available
channels. The option to change the channel list is on the
<link linkend="properties-general"><guilabel>General</guilabel> page</link> of
the device properties dialog that you can open by selecting the device in the
multimedia library and choosing the <guimenuitem>Properties...</guimenuitem>

<sect1 id="configuration-properties">
<title>File properties</title>

<para>&kplayer; has a unique feature that lets you choose many different options
on per-file basis. These options are called File Properties and are stored along
with the <acronym>URL</acronym> of each individual file or network
location.</para>

<para>There are two ways to set a file property. The easiest one is by holding
down the &Shift; key when changing a setting like video size or aspect, sound
volume, video contrast or brightness, etc. &kplayer; will apply the change to
the currently loaded file and remember it in the corresponding file property.
When it loads another file, it will revert the setting back to where it was
before the change (unless the other file also has the same property set). When
you load and play that first file again, &kplayer; will again apply the change
you made to the setting and keep it until you load another file or
<acronym>URL</acronym>.</para>

<para>The other way to set a file property is through the
<link linkend="properties">File Properties dialog</link>. The properties in the
dialog are arranged according to their function. General properties like
<guilabel>Name</guilabel>, <guilabel>Length</guilabel> and others are in the
<link linkend="properties-general">General</link> section. Properties that
control the video size are in the <link linkend="properties-size">Size</link>
section. Other sections contain properties that affect &kplayer; interaction
with <link linkend="howto-installation-mplayer">&mplayer;</link> and control
multimedia playback, including <link linkend="properties-video">video</link>,
