- * Switch to a new feed. The segment opened by the previously active pad, if

- *
- * This signal must be emitted when the element has been blocked via the <link
- * linkend="GstInputSelector-block">block</link> signal.
- *
- * If you have a stream with only one switch element, such as an audio-only
- * stream, a stream switch should be performed by first emitting the block
- * signal, and then emitting the switch signal with -1 for the stop and start
- * time values.
- *
- * The intention of the @stop_time and @start_time arguments is to allow
- * multiple switch elements to switch and maintain stream synchronization.
- * When switching a stream with multiple feeds, you will need as many switch
- * elements as you have feeds. For example, a feed with audio and video will
- * have one switch element between the audio feeds and one for video.
- *
- * A switch over multiple switch elements should be performed as follows:
- * First, emit the <link linkend="GstInputSelector-block">block</link>
- * signal, collecting the returned values. The maximum running time returned
- * by block should then be used as the time at which to close the previous
- * segment.
- *
- * Then, query the running times of the new audio and video pads that you will
- * switch to. Naturally, these pads are on separate switch elements. Take the
- * minimum running time for those streams and use it for the time at which to
- * open the new segment.
- *
- * If @pad is the same as the current active pad, the element will cancel any
- * previous block without adjusting segments.
