<div class="refsect1">
<a name="gst-plugins-base-plugins-multifdsink.description"></a><h2>Description</h2>
<p>
This plugin writes incoming data to a set of file descriptors. The
file descriptors can be added to multifdsink by emitting the <a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink-add" title='The "add" signal'><span class="type">"add"</span></a> signal. 
For each descriptor added, the <a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink-client-added" title='The "client-added" signal'><span class="type">"client-added"</span></a> signal will be called.
</p>
<p>
As of version 0.10.8, a client can also be added with the <a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink-add-full" title='The "add-full" signal'><span class="type">"add-full"</span></a> signal
that allows for more control over what and how much data a client 
initially receives.
</p>
<p>
Clients can be removed from multifdsink by emitting the <a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink-remove" title='The "remove" signal'><span class="type">"remove"</span></a> signal. For
each descriptor removed, the <a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink-client-removed" title='The "client-removed" signal'><span class="type">"client-removed"</span></a> signal will be called. The
<a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink-client-removed" title='The "client-removed" signal'><span class="type">"client-removed"</span></a> signal can also be fired when multifdsink decides that a
client is not active anymore or, depending on the value of the
<a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink--recover-policy" title='The "recover-policy" property'><span class="type">"recover-policy"</span></a> property, if the client is reading too slowly.
In all cases, multifdsink will never close a file descriptor itself.
The user of multifdsink is responsible for closing all file descriptors.
This can for example be done in response to the <a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink-client-fd-removed" title='The "client-fd-removed" signal'><span class="type">"client-fd-removed"</span></a> signal.
Note that multifdsink still has a reference to the file descriptor when the
<a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink-client-removed" title='The "client-removed" signal'><span class="type">"client-removed"</span></a> signal is emitted, so that "get-stats" can be performed on
the descriptor; it is therefore not safe to close the file descriptor in
the <a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink-client-removed" title='The "client-removed" signal'><span class="type">"client-removed"</span></a> signal handler, and you should use the 
<a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink-client-fd-removed" title='The "client-fd-removed" signal'><span class="type">"client-fd-removed"</span></a> signal to safely close the fd.
</p>
<p>
Multifdsink internally keeps a queue of the incoming buffers and uses a
separate thread to send the buffers to the clients. This ensures that no
client write can block the pipeline and that clients can read with different
speeds.
</p>
<p>
When adding a client to multifdsink, the <a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink--sync-method" title='The "sync-method" property'><span class="type">"sync-method"</span></a> property will define
which buffer in the queued buffers will be sent first to the client. Clients 
can be sent the most recent buffer (which might not be decodable by the 
client if it is not a keyframe), the next keyframe received in 
multifdsink (which can take some time depending on the keyframe rate), or the
last received keyframe (which will cause a simple burst-on-connect). 
Multifdsink will always keep at least one keyframe in its internal buffers
when the sync-mode is set to latest-keyframe.
</p>
<p>
As of version 0.10.8, there are additional values for the <a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink--sync-method" title='The "sync-method" property'><span class="type">"sync-method"</span></a> 
property to allow finer control over burst-on-connect behaviour. By selecting
the 'burst' method a minimum burst size can be chosen, 'burst-keyframe'
additionally requires that the burst begin with a keyframe, and 
'burst-with-keyframe' attempts to burst beginning with a keyframe, but will
prefer a minimum burst size even if it requires not starting with a keyframe.
</p>
<p>
Multifdsink can be instructed to keep at least a minimum amount of data
expressed in time or byte units in its internal queues with the 
<a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink--time-min" title='The "time-min" property'><span class="type">"time-min"</span></a> and <a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink--bytes-min" title='The "bytes-min" property'><span class="type">"bytes-min"</span></a> properties respectively.
These properties are useful if the application adds clients with the 
<a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink-add-full" title='The "add-full" signal'><span class="type">"add-full"</span></a> signal to make sure that a burst connect can
actually be honored. 
</p>
<p>
When streaming data, clients are allowed to read at a different rate than
the rate at which multifdsink receives data. If the client is reading too
fast, no data will be send to the client until multifdsink receives more
data. If the client, however, reads too slowly, data for that client will be 
queued up in multifdsink. Two properties control the amount of data 
(buffers) that is queued in multifdsink: <a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink--buffers-max" title='The "buffers-max" property'><span class="type">"buffers-max"</span></a> and 
<a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink--buffers-soft-max" title='The "buffers-soft-max" property'><span class="type">"buffers-soft-max"</span></a>. A client that falls behind by
<a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink--buffers-max" title='The "buffers-max" property'><span class="type">"buffers-max"</span></a> is removed from multifdsink forcibly.
</p>
<p>
A client with a lag of at least <a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink--buffers-soft-max" title='The "buffers-soft-max" property'><span class="type">"buffers-soft-max"</span></a> enters the recovery
procedure which is controlled with the <a class="link" href="gst-plugins-base-plugins-multifdsink.html#GstMultiFdSink--recover-policy" title='The "recover-policy" property'><span class="type">"recover-policy"</span></a> property.
A recover policy of NONE will do nothing, RESYNC_LATEST will send the most recently
received buffer as the next buffer for the client, RESYNC_SOFT_LIMIT
positions the client to the soft limit in the buffer queue and
RESYNC_KEYFRAME positions the client at the most recent keyframe in the
buffer queue.
</p>
<p>
multifdsink will by default synchronize on the clock before serving the 
buffers to the clients. This behaviour can be disabled by setting the sync 
property to FALSE. Multifdsink will by default not do QoS and will never
drop late buffers.

The GDP protocol wraps data buffers in a header that also carries format

The given file descriptor was removed from multifdsink. This signal will

for that.

In this callback, <em class="parameter"><code>gstmultifdsink</code></em> has removed all the information
associated with <em class="parameter"><code>fd</code></em> and it is therefore not possible to call get-stats
with <em class="parameter"><code>fd</code></em>. It is however safe to <code class="function">close()</code> and reuse <em class="parameter"><code>fd</code></em> in the callback.
