| <p>Concatenates streams together to one continous stream.</p> |
| <p>All streams but the current one are blocked until the current one |
| finished with <a href="../html/GstEvent.html#GST-EVENT-EOS:CAPS"><code class="literal">GST_EVENT_EOS</code></a>. Then the next stream is enabled, while |
| keeping the running time continous for <a href="../html/gstreamer-GstFormat.html#GST-FORMAT-TIME:CAPS"><code class="literal">GST_FORMAT_TIME</code></a> segments or |
| keeping the segment continous for <a href="../html/gstreamer-GstFormat.html#GST-FORMAT-BYTES:CAPS"><code class="literal">GST_FORMAT_BYTES</code></a> segments.</p> |
| <p>Streams are switched in the order in which the sinkpads were requested.</p> |
| <p>By default, the stream segment's base values are adjusted to ensure |
| the segment transitions between streams are continuous. In some cases, |
| it may be desirable to turn off these adjustments (for example, because |
| another downstream element like a streamsynchronizer adjusts the base |
| values on its own). The adjust-base property can be used for this purpose.</p> |
