<para>There are several ways to get help with &kplayer;. If you want to ask a

question, go to the <ulink url="irc://irc.freenode.net/#kplayer">#kplayer

who is of course subscribed to receive e-mail when a message is posted there.

<para>If you get this error when trying to play a file, you need to install

|
&mplayer; before you can use &kplayer;. This error can also happen if the name
|
|
of your &mplayer; executable is not <command>mplayer</command> or it is not in
|
|
the current path. In that case go to the
|
|
<link linkend="settings-advanced">Advanced</link> page in

<guilabel>&kplayer; Settings</guilabel> and give the executable name or the

full path in the <guilabel>Executable path</guilabel> field.</para>

<title>configure: error: Can't find X includes</title>
|
|
|
|
<para>That means that you are missing the X include files, which normally come
|
|
with the X development package. So look for a package in your distribution that
|
|
has files like X.h and XEvent.h. For example, on Debian it is called
|
|
<literal>xlibs-dev</literal>.</para>
|
|
|
|
<para>Similarly, if <command>configure</command> complains about missing Qt
|
|
files, you need to find and install the Qt development package. If you look
|
|
in the <filename>config.log</filename>, it will probably tell you the exact
|
|
name of the file it couldn't find, somewhere near the bottom. The
|
|
<filename>config.log</filename> file is quite verbose, so you would have to
|
|
scroll a few pages up from the bottom to find the place where it reports the
|
|
error.</para>

<para>Try playing the file with <command>mplayer</command> from the command

particular file, put them in the <link linkend="properties">File
|
|
Properties</link> for that file. Two options that sometimes help &mplayer; when
|
|
it cannot detect the file type automatically are <option>-vc</option> and
|
|
<option>-ac</option>, which correspond to the <guilabel>Codec</guilabel> options
|
|
on the <link linkend="properties-video">Video</link> and
|

<link linkend="properties-audio">Audio</link> pages in <guilabel>File

<para>If it is a playlist file but it does not have one of the standard playlist

file extensions, go to the

Properties</guilabel> and set the <guilabel>Playlist</guilabel> option to
|
|
<guilabel>yes</guilabel>. In rare cases a file that is not a playlist may have a
|
|
playlist extension. Then you will need to set the <guilabel>Playlist</guilabel>
|
|
property to <guilabel>no</guilabel>. For more details see the

<title>Cannot play any video files</title>
|
|
|
|
<para>If &kplayer; only plays audio files but not video files, there may be a
|
|
problem with the video output. By default &kplayer; uses
|
|
<link linkend="howto-installation-xvideo">XVideo extension</link> for video
|
|
output. If the extension is not enabled or is being used by another program like
|
|
<application>Kino</application>, &kplayer; may not be able to use a different
|
|
video output. You can either enable the XVideo extension or tell &kplayer; to
|
|
use another video output. See the
|
|
<link linkend="howto-configuration">Configuration micro-HOWTO</link> for
|
|
details.</para>

<title>Video plays fine, but there is no sound</title>
|
|
|
|
<para>Look in the <link linkend="parts-message-log">Message Log</link> to see
|
|
why &mplayer; cannot play audio. The most common problem is the audio device
|
|
being locked by another program. In this case the chief suspect is
|
|
<command>artsd</command>. Try running</para>
|
|
|
|
<para><userinput><command>killall</command> artsd</userinput></para>
|
|
|
|
<para>from the command line. If that helps then the permanent solution is to go
|
|
to the &kcontrolcenter; and disable &arts;. &arts; and everything based on it is
|
|
by far the worst part of &kde;. Fortunately it seems there are plans to finally
|
|
get rid of it in &kde; 4.</para>

uses to run &mplayer; to what you are using to play the file with &mplayer;.

Then start adding missing options one by one until you get the same problem
|
|
you are getting in &kplayer;. After you find out what option is causing the
|
|
problem, you can open the <link linkend="settings">configuration dialog</link>
|
|
in &kplayer; and remove or change that option. If you need to make the change
|
|
just for that one file, go to the <link linkend="properties">File

<title>Radio station takes too long to start playing</title>
|
|
|
|
<para>By default &kplayer; lets &mplayer; choose an optimal cache size. When
|
|
playing low bitrate media like a radio station, it may take a long time to fill
|
|
the cache if it is too big. If that happens, you can either choose a lower
|
|
<guilabel>Cache size</guilabel> setting or give a lower minimum cache size on
|
|
the <guilabel>Advanced</guilabel> page either globally in
|
|
<link linkend="settings-advanced">&kplayer; Settings</link> or in the
|
|
individual <link linkend="properties-advanced">File Properties</link>.
|
|
Enter the minimum cache size into the <guilabel>Additional command line
|
|
parameters</guilabel> field, for example <literal>-cache-min 5</literal>, or
|
|
choose <guilabel>set size</guilabel> for the <guilabel>Cache</guilabel> option
|
|
and enter a size in kilobytes. For more information on playing online media see
