It does exactly what its parent (<span class="type">rtpmux</span>) does, except 62that it prevent buffers coming over a regular sink_%u pad from going through 63for the duration of buffers that came in a priority_sink_%u pad.</p> 64<p>This is especially useful if a discontinuous source like dtmfsrc or 65rtpdtmfsrc are connected to the priority sink pads. This way, the generated 66DTMF signal can replace the recorded audio while the tone is being sent.</p> 67<div class="refsynopsisdiv"> 68<h2>Synopsis</h2> 69<div class="refsect2"> 70<a name="id-1.2.143.6.4.1"></a><h3>Element Information</h3> 71<div class="variablelist"><table border="0" class="variablelist"> 72<colgroup> 73<col align="left" valign="top"> 74<col> 75</colgroup> 76<tbody> 77<tr> 78<td><p><span class="term">plugin</span></p></td> 79<td> 80 <a class="link" href="gst-plugins-good-plugins-plugin-rtpmanager.html#plugin-rtpmanager">rtpmanager</a> 81 </td> 82</tr> 83<tr> 84<td><p><span class="term">author</span></p></td> 85<td>Zeeshan Ali <first.last@nokia.com></td> 86</tr> 87<tr> 88<td><p><span class="term">class</span></p></td> 89<td>Codec/Muxer</td> 90</tr> 91</tbody> 92</table></div> 93</div> 94<hr> 95<div class="refsect2"> 96<a name="id-1.2.143.6.4.2"></a><h3>Element Pads</h3> 97<div class="variablelist"><table border="0" class="variablelist"> 98<colgroup> 99<col align="left" valign="top"> 100<col> 101</colgroup> 102<tbody> 103<tr> 104<td><p><span class="term">name</span></p></td> 105<td>priority_sink_%u</td> 106</tr> 107<tr> 108<td><p><span class="term">direction</span></p></td> 109<td>sink</td> 110</tr> 111<tr> 112<td><p><span class="term">presence</span></p></td> 113<td>request</td> 114</tr> 115<tr> 116<td><p><span class="term">details</span></p></td> 117<td>application/x-rtp</td> 118</tr> 119</tbody> 120</table></div> 121<div class="variablelist"><table border="0" class="variablelist"> 122<colgroup> 123<col align="left" valign="top"> 124<col> 125</colgroup> 126<tbody> 127<tr> 128<td><p><span class="term">name</span></p></td> 129<td>sink_%u</td> 130</tr> 131<tr> 132<td><p><span class="term">direction</span></p></td> 133<td>sink</td> 134</tr> 135<tr> 136<td><p><span class="term">presence</span></p></td> 137<td>request</td> 138</tr> 139<tr> 140<td><p><span class="term">details</span></p></td> 141<td>application/x-rtp</td> 142</tr> 143</tbody> 144</table></div> 145<div class="variablelist"><table border="0" class="variablelist"> 146<colgroup> 147<col align="left" valign="top"> 148<col> 149</colgroup> 150<tbody> 151<tr> 152<td><p><span class="term">name</span></p></td> 153<td>src</td> 154</tr> 155<tr> 156<td><p><span class="term">direction</span></p></td> 157<td>source</td> 158</tr> 159<tr> 160<td><p><span class="term">presence</span></p></td> 161<td>always</td> 162</tr> 163<tr> 164<td><p><span class="term">details</span></p></td> 165<td>application/x-rtp</td> 166</tr> 167</tbody> 168</table></div> 169</div> 170</div> 171</div> 172<div class="refsect1"> 173<a name="gst-plugins-good-plugins-rtpdtmfmux.functions_details"></a><h2>Functions</h2> 174<p></p> 175</div> 176<div class="refsect1"> 177<a name="gst-plugins-good-plugins-rtpdtmfmux.other_details"></a><h2>Types and Values</h2> 178<div class="refsect2"> 179<a name="GstRTPDTMFMux-struct"></a><h3>struct GstRTPDTMFMux</h3> 180<pre class="programlisting">struct GstRTPDTMFMux;</pre> 181<p>The opaque <a class="link" href="gst-plugins-good-plugins-rtpdtmfmux.html#GstRTPDTMFMux"><span class="type">GstRTPDTMFMux</span></a> structure.</p> 182</div> 183</div> 184<div class="refsect1"> 185<a name="gst-plugins-good-plugins-rtpdtmfmux.see-also"></a><h2>See Also</h2> 186<p>rtpdtmfsrc, dtmfsrc, rtpmux</p> 187</div> 188</div> 189<div class="footer"> 190<hr>Generated by GTK-Doc V1.28</div> 191</body> 192</html>
