| <p>A Src that inputs data from Jack ports.</p> |
| <p>It will create N Jack ports named in_<name>_<num> where |
| <name> is the element name and <num> is starting from 1. |
| Each port corresponds to a gstreamer channel.</p> |
| <p>The samplerate as exposed on the caps is always the same as the samplerate of |
| the jack server.</p> |
| <p>When the <a class="link" href="gst-plugins-good-plugins-jackaudiosrc.html#GstJackAudioSrc--connect" title="The “connect” property"><span class="type">“connect”</span></a> property is set to auto, this element |
| will try to connect each input port to a random physical jack output pin. </p> |
| <p>When the <a class="link" href="gst-plugins-good-plugins-jackaudiosrc.html#GstJackAudioSrc--connect" title="The “connect” property"><span class="type">“connect”</span></a> property is set to none, the element will |
| accept any number of output channels and will create (but not connect) an |
| input port for each channel.</p> |
| <p>The element will generate an error when the Jack server is shut down when it |
| was PAUSED or PLAYING. This element does not support dynamic rate and buffer |
| size changes at runtime.</p> |
