When this 843option is disabled, RTP timestamps are generated from GST_BUFFER_PTS of 844each payloaded buffer. The PTSes of buffers may not necessarily increment 845with the amount of data in each input buffer, consider e.g. the case where 846the buffer arrives from a network which means that the PTS is unrelated to 847the amount of data. Because the RTP timestamps are generated from 848GST_BUFFER_PTS this can result in RTP timestamps that also don't increment 849with the amount of data in the payloaded packet. To circumvent this it is 850possible to set the perfect rtptime option enabled. When this option is 851enabled the payloader will increment the RTP timestamps based on 852GST_BUFFER_OFFSET which relates to the amount of data in each packet 853rather than the GST_BUFFER_PTS of each buffer and therefore the RTP 854timestamps will more closely correlate with the amount of data in each 855buffer. Currently GstRTPBasePayload is limited to handling perfect RTP 856timestamps for audio streams.</p> 857<p>Flags: Read / Write</p> 858<p>Default value: TRUE</p> 859</div> 860<hr> 861<div class="refsect2"> 862<a name="GstRTPBasePayload--pt"></a><h3>The <code class="literal">“pt”</code> property</h3> 863<pre class="programlisting"> “pt” <a href="/usr/share/gtk-doc/html/glib/glib-Basic-Types.html#guint"><span class="type">guint</span></a></pre> 864<p>The payload type of the packets.</p> 865<p>Flags: Read / Write</p> 866<p>Allowed values: <= 127</p> 867<p>Default value: 96</p> 868</div> 869<hr> 870<div class="refsect2"> 871<a name="GstRTPBasePayload--ptime-multiple"></a><h3>The <code class="literal">“ptime-multiple”</code> property</h3> 872<pre class="programlisting"> “ptime-multiple” <a href="/usr/share/gtk-doc/html/glib/glib-Basic-Types.html#gint64"><span class="type">gint64</span></a></pre> 873<p>Force buffers to be multiples of this duration in ns (0 disables)</p> 874<p>Flags: Read / Write</p> 875<p>Allowed values: >= 0</p> 876<p>Default value: 0</p> 877</div> 878<hr> 879<div class="refsect2"> 880<a name="GstRTPBasePayload--seqnum"></a><h3>The <code class="literal">“seqnum”</code> property</h3> 881<pre class="programlisting"> “seqnum” <a href="/usr/share/gtk-doc/html/glib/glib-Basic-Types.html#guint"><span class="type">guint</span></a></pre> 882<p>The RTP sequence number of the last processed packet.</p> 883<p>Flags: Read</p> 884<p>Allowed values: <= 65535</p> 885<p>Default value: 0</p> 886</div> 887<hr> 888<div class="refsect2"> 889<a name="GstRTPBasePayload--seqnum-offset"></a><h3>The <code class="literal">“seqnum-offset”</code> property</h3> 890<pre class="programlisting"> “seqnum-offset” <a href="/usr/share/gtk-doc/html/glib/glib-Basic-Types.html#gint"><span class="type">gint</span></a></pre> 891<p>Offset to add to all outgoing seqnum (-1 = random).</p> 892<p>Flags: Read / Write</p> 893<p>Allowed values: [-1,65535]</p> 894<p>Default value: -1</p> 895</div> 896<hr> 897<div class="refsect2"> 898<a name="GstRTPBasePayload--source-info"></a><h3>The <code class="literal">“source-info”</code> property</h3> 899<pre class="programlisting"> “source-info” <a href="/usr/share/gtk-doc/html/glib/glib-Basic-Types.html#gboolean"><span class="type">gboolean</span></a></pre> 900<p>Enable writing the CSRC field in allocated RTP header based on RTP source 901information found in the input buffer's <a class="link" href="gst-plugins-base-libs-GstMeta-for-RTP.html#GstRTPSourceMeta" title="struct GstRTPSourceMeta"><span class="type">GstRTPSourceMeta</span></a>.</p> 902<p>Flags: Read / Write</p> 903<p>Default value: FALSE</p> 904<p class="since">Since: <a class="link" href="ix03.html#api-index-1.16">1.16</a></p> 905</div> 906<hr> 907<div class="refsect2"> 908<a name="GstRTPBasePayload--ssrc"></a><h3>The <code class="literal">“ssrc”</code> property</h3> 909<pre class="programlisting"> “ssrc” <a href="/usr/share/gtk-doc/html/glib/glib-Basic-Types.html#guint"><span class="type">guint</span></a></pre> 910<p>The SSRC of the packets (default == random).</p> 911<p>Flags: Read / Write</p> 912<p>Default value: 4294967295</p> 913</div> 914<hr> 915<div class="refsect2"> 916<a name="GstRTPBasePayload--stats"></a><h3>The <code class="literal">“stats”</code> property</h3> 917<pre class="programlisting"> “stats” <a href="/usr/share/gtk-doc/html/gstreamer-1.0/GstStructure.html#GstStructure-struct"><span class="type">GstStructure</span></a> *</pre> 918<p>Various payloader statistics retrieved atomically (and are therefore 919synchroized with each other), these can be used e.g. to generate an 920RTP-Info header.
