++ *
++ * This signal must be emitted when the element has been blocked via the <link

++ *
++ * 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.
