	<p>On BSD/Linux systems there are a plethora of audio players. In streamtuner2 you can
	<link xref="configuration">configure</link> most of them as target application. Mostly it makes sense to use a single
	application for all audio formats. But at least the */* media type should be handled
	by a generic player, like vlc.</p>

	<p>Some audio players open a second instance when you actually want to switch radios.
	In this case it's a common workaround to write <code>pkill vlc ; vlc %u</code> instead,
	which ends the previous player process and starts it anew.
        For VLC there's however also the <code>--one-instance</code> option, which sometimes
        works better. (And sometimes not.)</p>

	<p>Any listed application can be invoked with a different kind of
	URL or filename. Most are rather flexible, but some depend on
	specific playlist file types or URLs. You can control this by adding
	a placeholder after the configured application name:</p>

	<table shade="rows" rules="rows cols">
	<thead>	<tr><td><p>Placeholder</p></td><td><p>Alternatives</p></td><td><p>URL/Filename type</p></td></tr> </thead>
		<tr><td><p>%pls</p></td><td><p>%url %u %r</p></td><td><p>Either a remote .pls resource (fastest), or a local .pls file (if converted)</p></td></tr>
		<tr><td><p>%m3u</p></td><td><p>%f %g %m</p></td><td><p>Provides a local .m3u file for the streaming station</p></td></tr>

		<tr><td><p>%srv</p></td><td><p>%d %s</p></td><td><p>Direct link to first streaming address, e.g. http://72.5.9.33:7500</p></td></tr>
		<tr><td><p>%xspf</p></td><td><p>%x</p></td><td><p>Xiph.org shareable playlist format (for modern players)</p></td></tr>
		<tr><td><p>%jspf</p></td><td><p>%j</p></td><td><p>JSON playlist format (widely unsupported)</p></td></tr>
		<tr><td><p>%asx</p></td><td><p></p></td><td><p>Some obscure Windows playlist format (don't use that)</p></td></tr>
		<tr><td><p>%smil</p></td><td><p></p></td><td><p>Standardized multimedia sequencing lists (which nobody uses either)</p></td></tr>
	</table>

        <p>Preferrably use the long %abbr names for configuration.</p>
        
	<note style="info"><p>Most audio players like pls, yet sometimes the
	older m3u format more.  Streamripper requires %srv for recording.</p>
	
	<p>Leave it to the default %pls to avoid Streamtuner2 doing unneeded
	extra conversions (just delays playback).</p> </note>

    <p>Application names are most always lowercase binary names. Double click an entry to edit it.
    After editing the icon next to the application name will be updated. If it stays green, it's
    likely to work. If it turns red / into a stop symbol, then the entered name is likely incorrect.</p>

   <p><media type="image" src="img/configapps.png" mime="image/png" /></p>

    <p>After the application name, you can use a placeholder like "<var>%pls</var>" (default),
    or "<var>%m3u</var>" and "<var>%srv</var>". See <link xref="config_apps#placeholders">placeholders</link>.</p>

    <p>Catch-all entries like <var>*/*</var> or a generic <var>audio/*</var> entry allow to configure a default player.
    While <var>video/youtube</var> is specific to the Youtube channel. And <var>url/http</var> a pseudo MIME type
    to configure a web browser (for station homepages).</p>
    
    <p>You can remove default entries by clearing both the Format field and its associated Application.
    Add completely new associations through the emtpy line. (Reopen the dialog to add another one.)</p>
