| <a name="GstPad.description"></a><h2>Description</h2> |
| <p>A <a class="link" href="GstElement.html" title="GstElement"><span class="type">GstElement</span></a> is linked to other elements via "pads", which are extremely |
| light-weight generic link points.</p> |
| <p>Pads have a <a class="link" href="GstPad.html#GstPadDirection" title="enum GstPadDirection"><span class="type">GstPadDirection</span></a>, source pads produce data, sink pads consume |
| data.</p> |
| <p>Pads are typically created from a <a class="link" href="GstPadTemplate.html" title="GstPadTemplate"><span class="type">GstPadTemplate</span></a> with |
| <a class="link" href="GstPad.html#gst-pad-new-from-template" title="gst_pad_new_from_template ()"><code class="function">gst_pad_new_from_template()</code></a> and are then added to a <a class="link" href="GstElement.html" title="GstElement"><span class="type">GstElement</span></a>. This usually |
| happens when the element is created but it can also happen dynamically based |
| on the data that the element is processing or based on the pads that the |
| application requests.</p> |
| <p>Pads without pad templates can be created with <a class="link" href="GstPad.html#gst-pad-new" title="gst_pad_new ()"><code class="function">gst_pad_new()</code></a>, |
| which takes a direction and a name as an argument. If the name is <a href="https://developer.gnome.org/glib/unstable/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>, |
| then a guaranteed unique name will be assigned to it.</p> |
| <p>A <a class="link" href="GstElement.html" title="GstElement"><span class="type">GstElement</span></a> creating a pad will typically use the various |
| gst_pad_set_*_function() calls to register callbacks for events, queries or |
| dataflow on the pads.</p> |
| <p>gst_pad_get_parent() will retrieve the <a class="link" href="GstElement.html" title="GstElement"><span class="type">GstElement</span></a> that owns the pad.</p> |
| <p>After two pads are retrieved from an element by <a class="link" href="GstElement.html#gst-element-get-static-pad" title="gst_element_get_static_pad ()"><code class="function">gst_element_get_static_pad()</code></a>, |
| the pads can be linked with <a class="link" href="GstPad.html#gst-pad-link" title="gst_pad_link ()"><code class="function">gst_pad_link()</code></a>. (For quick links, |
| you can also use <a class="link" href="GstElement.html#gst-element-link" title="gst_element_link ()"><code class="function">gst_element_link()</code></a>, which will make the obvious |
| link for you if it's straightforward.). Pads can be unlinked again with |
| <a class="link" href="GstPad.html#gst-pad-unlink" title="gst_pad_unlink ()"><code class="function">gst_pad_unlink()</code></a>. <a class="link" href="GstPad.html#gst-pad-get-peer" title="gst_pad_get_peer ()"><code class="function">gst_pad_get_peer()</code></a> can be used to check what the pad is |
| linked to.</p> |
| <p>Before dataflow is possible on the pads, they need to be activated with |
| <a class="link" href="GstPad.html#gst-pad-set-active" title="gst_pad_set_active ()"><code class="function">gst_pad_set_active()</code></a>.</p> |
| <p>gst_pad_query() and <a class="link" href="GstPad.html#gst-pad-peer-query" title="gst_pad_peer_query ()"><code class="function">gst_pad_peer_query()</code></a> can be used to query various |
| properties of the pad and the stream.</p> |
| <p>To send a <a class="link" href="GstEvent.html" title="GstEvent"><span class="type">GstEvent</span></a> on a pad, use <a class="link" href="GstPad.html#gst-pad-send-event" title="gst_pad_send_event ()"><code class="function">gst_pad_send_event()</code></a> and |
| <a class="link" href="GstPad.html#gst-pad-push-event" title="gst_pad_push_event ()"><code class="function">gst_pad_push_event()</code></a>. Some events will be sticky on the pad, meaning that |
| after they pass on the pad they can be queried later with |
| <a class="link" href="GstPad.html#gst-pad-get-sticky-event" title="gst_pad_get_sticky_event ()"><code class="function">gst_pad_get_sticky_event()</code></a> and <a class="link" href="GstPad.html#gst-pad-sticky-events-foreach" title="gst_pad_sticky_events_foreach ()"><code class="function">gst_pad_sticky_events_foreach()</code></a>. |
| <a class="link" href="GstPad.html#gst-pad-get-current-caps" title="gst_pad_get_current_caps ()"><code class="function">gst_pad_get_current_caps()</code></a> and <a class="link" href="GstPad.html#gst-pad-has-current-caps" title="gst_pad_has_current_caps ()"><code class="function">gst_pad_has_current_caps()</code></a> are convenience |
| functions to query the current sticky CAPS event on a pad.</p> |
| <p>GstElements will use <a class="link" href="GstPad.html#gst-pad-push" title="gst_pad_push ()"><code class="function">gst_pad_push()</code></a> and <a class="link" href="GstPad.html#gst-pad-pull-range" title="gst_pad_pull_range ()"><code class="function">gst_pad_pull_range()</code></a> to push out |
| or pull in a buffer.</p> |
| <p>The dataflow, events and queries that happen on a pad can be monitored with |
| probes that can be installed with <a class="link" href="GstPad.html#gst-pad-add-probe" title="gst_pad_add_probe ()"><code class="function">gst_pad_add_probe()</code></a>. <a class="link" href="GstPad.html#gst-pad-is-blocked" title="gst_pad_is_blocked ()"><code class="function">gst_pad_is_blocked()</code></a> |
| can be used to check if a block probe is installed on the pad. |
| <a class="link" href="GstPad.html#gst-pad-is-blocking" title="gst_pad_is_blocking ()"><code class="function">gst_pad_is_blocking()</code></a> checks if the blocking probe is currently blocking the |
| pad. <a class="link" href="GstPad.html#gst-pad-remove-probe" title="gst_pad_remove_probe ()"><code class="function">gst_pad_remove_probe()</code></a> is used to remove a previously installed probe |
| and unblock blocking probes if any.</p> |
| <p>Pad have an offset that can be retrieved with <a class="link" href="GstPad.html#gst-pad-get-offset" title="gst_pad_get_offset ()"><code class="function">gst_pad_get_offset()</code></a>. This |
| offset will be applied to the running_time of all data passing over the pad. |
| <a class="link" href="GstPad.html#gst-pad-set-offset" title="gst_pad_set_offset ()"><code class="function">gst_pad_set_offset()</code></a> can be used to change the offset.</p> |
| <p>Convenience functions exist to start, pause and stop the task on a pad with |
| <a class="link" href="GstPad.html#gst-pad-start-task" title="gst_pad_start_task ()"><code class="function">gst_pad_start_task()</code></a>, <a class="link" href="GstPad.html#gst-pad-pause-task" title="gst_pad_pause_task ()"><code class="function">gst_pad_pause_task()</code></a> and <a class="link" href="GstPad.html#gst-pad-stop-task" title="gst_pad_stop_task ()"><code class="function">gst_pad_stop_task()</code></a> |
