+ * 2) Non-starvation on multiple stream
+ *
+ * * If more than one stream is used with the element, the streams' queues
+ * will be dynamically grown (up to a limit), in order to ensure that no
+ * stream is risking data starvation. This guarantees that at any given
+ * time there are at least N bytes queued and available for each individual

+ * 3) Non-linked srcpads graceful handling
+ *
+ * * In order to better support dynamic switching between streams, the multiqueue
+ * (unlike the current GStreamer queue) continues to push buffers on non-linked
+ * pads rather than shutting down. In addition, to prevent a non-linked stream from very quickly consuming all
+ * available buffers and thus 'racing ahead' of the other streams, the element
+ * must ensure that buffers and inlined events for a non-linked stream are pushed
+ * in the same order as they were received, relative to the other streams
+ * controlled by the element. This means that a buffer cannot be pushed to a
+ * non-linked pad any sooner than buffers in any other stream which were received
+ * before it.
+ *
+ * Data is queued until one of the limits specified by the
+ * #GstMultiQueue:max-size-buffers, #GstMultiQueue:max-size-bytes and/or
+ * #GstMultiQueue:max-size-time properties has been reached. Any attempt to push
+ * more buffers into the queue will block the pushing thread until more space
+ * becomes available. #GstMultiQueue:extra-size-buffers,
+ *
+ *
+ * #GstMultiQueue:extra-size-bytes and #GstMultiQueue:extra-size-time are
+ * currently unused.
+ *
+ * The default queue size limits are 5 buffers, 10MB of data, or
+ * two second worth of data, whichever is reached first. Note that the number
+ * of buffers will dynamically grow depending on the fill level of
+ * other queues.
+ *
+ * The #GstMultiQueue::underrun signal is emitted when all of the queues
+ * are empty. The #GstMultiQueue::overrun signal is emitted when one of the
+ * queues is filled.
+ * Both signals are emitted from the context of the streaming thread.
+ *
+ * When using #GstMultiQueue:sync-by-running-time the unlinked streams will
+ * be throttled by the highest running-time of linked streams. This allows
+ * further relinking of those unlinked streams without them being in the
+ * future (i.e. to achieve gapless playback).
+ * When dealing with streams which have got different consumption requirements
+ * downstream (ex: video decoders which will consume more buffer (in time) than
+ * audio decoders), it is recommended to group streams of the same type
+ * by using the pad "group-id" property. This will further throttle streams
+ * in time within that group.

+ * buffering_percent = 0% means overall buffering_level is at the low watermark.
+ * buffering_percent = 100% means overall buffering_level is at the high watermark.
+ * buffering_percent is used for determining if the fill level has reached
+ * the high watermark, and for producing BUFFERING messages. This value
+ * always uses a 0..100 range (since it is a percentage).
+ *
+ * To avoid future confusions, whenever "buffering level" is mentioned, it
+ * refers to the absolute level which is in the 0..MAX_BUFFERING_LEVEL
+ * range. Whenever "buffering_percent" is mentioned, it refers to the
