108 <a name="gst-plugins-base-plugins-multifdsink.description"></a><h2>Description</h2>
110 This plugin writes incoming data to a set of file descriptors. The
111 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.
112 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.
115 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
116 that allows for more control over what and how much data a client
120 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
121 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
122 <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
123 client is not active anymore or, depending on the value of the
124 <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.
125 In all cases, multifdsink will never close a file descriptor itself.
126 The user of multifdsink is responsible for closing all file descriptors.
127 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.
128 Note that multifdsink still has a reference to the file descriptor when the
129 <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
130 the descriptor; it is therefore not safe to close the file descriptor in
131 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
132 <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.
135 Multifdsink internally keeps a queue of the incoming buffers and uses a
136 separate thread to send the buffers to the clients. This ensures that no
137 client write can block the pipeline and that clients can read with different
141 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
142 which buffer in the queued buffers will be sent first to the client. Clients
143 can be sent the most recent buffer (which might not be decodable by the
144 client if it is not a keyframe), the next keyframe received in
145 multifdsink (which can take some time depending on the keyframe rate), or the
146 last received keyframe (which will cause a simple burst-on-connect).
147 Multifdsink will always keep at least one keyframe in its internal buffers
148 when the sync-mode is set to latest-keyframe.
151 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>
152 property to allow finer control over burst-on-connect behaviour. By selecting
153 the 'burst' method a minimum burst size can be chosen, 'burst-keyframe'
154 additionally requires that the burst begin with a keyframe, and
155 'burst-with-keyframe' attempts to burst beginning with a keyframe, but will
156 prefer a minimum burst size even if it requires not starting with a keyframe.
159 Multifdsink can be instructed to keep at least a minimum amount of data
160 expressed in time or byte units in its internal queues with the the
161 <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.
162 These properties are useful if the application adds clients with the
163 <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
167 When streaming data, clients are allowed to read at a different rate than
168 the rate at which multifdsink receives data. If the client is reading too
169 fast, no data will be send to the client until multifdsink receives more
170 data. If the client, however, reads too slowly, data for that client will be
171 queued up in multifdsink. Two properties control the amount of data
172 (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
173 <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
174 <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.
177 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
178 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.
179 A recover policy of NONE will do nothing, RESYNC_LATEST will send the most recently
180 received buffer as the next buffer for the client, RESYNC_SOFT_LIMIT
181 positions the client to the soft limit in the buffer queue and
182 RESYNC_KEYFRAME positions the client at the most recent keyframe in the
186 multifdsink will by default synchronize on the clock before serving the
187 buffers to the clients. This behaviour can be disabled by setting the sync
188 property to FALSE. Multifdsink will by default not do QoS and will never
