<title>Configuration / Settings dialog</title>
There are various options for streamtuner2, available under <guiseq><gui>Edit</gui>
<gui>Preferences</gui></guiseq> or via <key>F12</key>.
<p><media type="image" src="img/configtabs.png" mime="image/png" /></p>
<title>It's grouped into:</title>
<title>🔊 <link xref="#apps">Player</link></title>
<p>Associates media formats to audio player applications or recording tools.</p>
<title>☑ <link xref="#gui">Options</link></title>
<p>Influences the display of all stream/station lists, and contains some
behaviour and system settings.</p>
<title>📻 <link xref="#plugins">Channel Plugins</link></title>
<p>Allows to enable or disable channel tabs. Each can have specific
options, which can be configured here.</p>
<title>🔌 <link xref="#plugins">Feature Plugins</link></title>
<p>Another class of plugins enables internal functions, or adds extra menu
entries, or further configuration options.</p>
<title>📦 <link xref="pluginmanager2">Add</link></title>
<p>The <link xref="pluginmanager2">Plugin Manager 2</link> adds another
tab for updating or installing new plugins.</p>
<title>Player application settings</title>
<p>MIME types are abstract identifiers for media types. <var>Audio/mpeg</var> for
example represents MP3 files, and <var>audio/ogg</var> means OGG Vorbis. And the player
setting dialog simply associates an audio type with a playback application:</p>
<p><media type="image" src="img/configapps.png" mime="image/png" /></p>
<item><p><link xref="config_apps">Application names</link> are most
always lowercase binary names.</p></item>
<item><p> 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. (Only works on U*ix-systems.)</p></item>
<item><p>After the application name, you can optionally use
<link xref="config_apps#placeholders">a placeholder</link>:</p>
<item><p><var>%pls</var> → default format</p></item>
<item><p><var>%m3u</var> → older scheme</p></item>
<item><p><var>%xspf</var> → modern playlists,</p></item>
<item><p><var>%srv</var> → for direct streaming URLs</p></item>
<item><p>The format entries can specify generic or custom handlers:</p>
<item><p>Catch-all specifiers like <var>*/*</var> or a generic
<var>audio/*</var> entry allow to configure a default
<item><p>While <var>video/youtube</var> is specific to the Youtube
<item><p>And <var>url/http</var> a pseudo MIME type to configure a
web browser (for station homepages).</p></item>
<item><p>In practice you only needed one entry for <var>audio/*</var>
and one for <var>video/*</var>, both can use the same player even.
<item><p> You can remove existing entries by clearing both the Format
field and its associated Application. Add completely new associations
through the emtpy line. </p></item>
<p>The second block of entries in the 'Apps' section specifies recording applications.
Here streamripper is preconfigured for audio streams, and youtube-dl for Youtube videos for instance.</p>
<table shade="rows" rules="rows cols">
<tr><td><p><var>audio/*</var></p></td> <td><p><cmd>xterm -e streamripper %srv</cmd></p></td></tr>
<tr><td><p><var>video/youtube</var></p></td> <td><p><cmd>xterm -e "youtube-dl %srv"</cmd></p></td></tr>
<p>To define a target directory, you can often add commandline arguments to each. Also it's typically
helpful to leave the xterm prefix on, so you can follow the processing state.</p>
<title>☑ Show bookmark star</title>
<p>Bookmarked stations will be marked with a ★ star in all other station lists / categories.
That doesn't often work for the same station entry from two different channel services / tabs though.</p>
<title>☑ Save window states</title>
<p>Automatically remember window size, selected channel tab, categories, or selected station.
Also keeps the width of station list columns. If disabled, you can manually save the current
layout/selections via <guiseq><gui>Edit</gui> <gui>Save States</gui></guiseq>.</p>
<title>☑ Update window title</title>
<p>When switching channel tabs, the Streamtuner2 window title usually gets the current
channel name appended (such as "- Shoutcast" or "- Xiph"). You can disable this if it
looks confusing. (Requires a restart to fully take effect.)</p>
<item><title><link type="guide" xref="favicon">→ Favicon plugin options</link></title></item>
<title>☑ Prefer HTML traversing (PyQuery) over regex</title>
<p>Some channels provide proper APIs to fetch station lists. Others are just websites that
require scraping listings out. Most channel tabs provide two alternative methods for that.
The DOM/HTML selection method is sometimes slower, but more reliable. As fallback streamtuner2
plugins often use a regex to match text. Occasionally the regex method is surprisingly more exact,
because directory services often use frightful unstructured HTML. If available, both methods
are tried. You can influence the order with this setting, and thus speed it up.</p>
<title>🔟 Limit stream number</title>
<p> Constrains the length of station lists per category.
The number of stations option is not honored by all channel plugins. Often it's not possible to
load more or fewer station entries. Some plugins have own settings (in the 'Plugins' section) even.
For the major plugins this however limits how many scrollable entries appear in the stream lists.</p>
<title>☑ Retain deleted stations</title> <p>When enabled, keeps old station entries when
updating/reloading a category/genre. Services often forget stations or throw them out when inavailable.
With this option enabled, these entries are kept in streamtuner2 as strikethrough entries (often
at the end of the list).</p>
<title>☑ Update favourites from freshened URLs</title>
<p>Streaming URLs in bookmarked stations get renewed on category reloads/updates. This isn't
very reliable, as often station titles change together with the streaming URLs.</p>
<title>☑ Save station lists after updates</title>
<p>After reloading (<key>F5</key>) the updated station lists are
automatically saved. For favicon updates or drag and drop events this
only happens automatically when this option is set.</p>
<title>☑ Reuse .m3u/.pls files</title> <p>When converting online station playlists,
streamtuner2 creates temporary files like <var>shoutcast.11539398391891.m3u</var> for
your audio player. It'll keep those files around in /tmp/streamtuner2 until you quit.
That speeds up switching between and reconnecting to a previous station. It's in
particular necessary when you use <key>⏭</key> or <key>⏪</key> directly in your player.
For <var>%pls</var> references your player typically uses the online-only playlist
files anyway. If you disable this option, then converted pls/m3u/xspf files get
<title>☑ Forgo any playlist conversion</title>
<p>Per default most server playlists (be they .pls or .m3u, .xpsf) are converted.
All player/recording apps receive a default <var>%pls</var> file normally.
Set this option to disable any such placeholders from the Player tab, and avoid
streamtuner2 pre-downloading any m3u/pls/xspf. Instead your audio player gets passed
the literal server/playlist streaming URL then.</p> <note><p>Note that this is only
a minor speedup, but may trip up some applications. A few channel sources don't
even provide standard stream addresses and playlists. (Jamendo albums for example really
need pre-conversion; no audio player can deal with such custom JSON playlists).
In short: you don't normally want to enable this flag - unless you run into problems
with streamtuner2 taking too long, or when it hangs by accidentially downloading streams
<title>🔠 Temporary files</title> <p>Streamtuner2 creates temporary .m3u files - for audio
players that are configured to use %m3u files instead of %pls or %srv URLs. For
archival purposes you might want to set a dedicated directory for this. In recent
versions streamtuner2 will create a <file>/tmp/streamtuner2</file> directory for itself.
(You cannot set just `/tmp` anymore, because that will be mapped to the longer name.
You can trick the old behaviour with `/tmp/.` however. Don't do that unless you have a
<title>🔠 Config directory</title>
<p>Is where streamtuner2 keeps its <file>settings.json</file> and channel caches, favicons, etc.
You can't set this in the config dialog. This is just for display. Set the <sys>XDG_CONFIG_HOME</sys>
environment variable to adapt.</p>
<title>☑ Enable debug messages</title>
<p>If you start streamtuner2 from a terminal window (xterm/rxvt), you can get a load of state
and processing or debug infos. Enable this only for testing, as it might slow down station
<title>☑ Disable threading</title> <p>Now "threading" is a somewhat technical term. It
means that an application runs different tasks internally at the same time. It's used
for snappier interfaces. However, it's also difficult to get right at times. In
Streamtuner2 some concurrent tasks conflict with updating the Gtk3 user interface.
Which is why the application may crash even on reloading station lists or when switching
between categories too quickly. This is only an issue for Python3 on Gtk3 with
streamtuner2. In such cases you can disable the concurrent-tasking mode. The GUI will
appear slower at times, and freeze between fetching lists, but remains stable on the
upside. There's also a command line flag <cmd>--nt</cmd> to enable this workaround.</p>
<title>Channel and feature plugins and settings</title>
<td><p>The <key>📻 Channels</key> tab shows all available directory
<td><p>While the <key>🔌 Features</key> group provides internal or menu
<p>Disabling or enabling a plugin however requires a restart of Streamtuner2
to take effect. (Unless the <link xref="pluginmanager2">Plugin Manager 2</link>
is enabled, with its <key>📦 Add</key> tab visible.)</p>
<p><media type="image" src="img/configplugins.png" mime="image/png" /></p>
<p>Each plugin can have its own little list of extra options. They'll be
applied right away for already active channel/feature plugins.</p>
<note style="note"><p>If you want to find out more about the short option descriptions (most settings are checkboxes),
please have a look into the channels directory /usr/share/streamtuner2/channels/ and corresponding
*.py files. These are somewhat readable even to non-programmers, and sometimes contain more information.</p></note>
