26 * SECTION:element-multiqueue
28 * @see_also: #GstQueue
30 * Multiqueue is similar to a normal #GstQueue with the following additional
33 * 1) Multiple streamhandling
35 * * The element handles queueing data on more than one stream at once. To
36 * achieve such a feature it has request sink pads (sink%u) and
37 * 'sometimes' src pads (src%u). When requesting a given sinkpad with gst_element_request_pad(),
38 * the associated srcpad for that stream will be created.
39 * Example: requesting sink1 will generate src1.
41 * 2) Non-starvation on multiple stream
43 * * If more than one stream is used with the element, the streams' queues
44 * will be dynamically grown (up to a limit), in order to ensure that no
45 * stream is risking data starvation. This guarantees that at any given
46 * time there are at least N bytes queued and available for each individual
47 * stream. If an EOS event comes through a srcpad, the associated queue will be
48 * considered as 'not-empty' in the queue-size-growing algorithm.
50 * 3) Non-linked srcpads graceful handling
52 * * In order to better support dynamic switching between streams, the multiqueue
53 * (unlike the current GStreamer queue) continues to push buffers on non-linked
54 * pads rather than shutting down. In addition, to prevent a non-linked stream from very quickly consuming all
55 * available buffers and thus 'racing ahead' of the other streams, the element
56 * must ensure that buffers and inlined events for a non-linked stream are pushed
57 * in the same order as they were received, relative to the other streams
58 * controlled by the element. This means that a buffer cannot be pushed to a
59 * non-linked pad any sooner than buffers in any other stream which were received
62 * Data is queued until one of the limits specified by the
63 * #GstMultiQueue:max-size-buffers, #GstMultiQueue:max-size-bytes and/or
64 * #GstMultiQueue:max-size-time properties has been reached. Any attempt to push
65 * more buffers into the queue will block the pushing thread until more space
66 * becomes available. #GstMultiQueue:extra-size-buffers,
69 * #GstMultiQueue:extra-size-bytes and #GstMultiQueue:extra-size-time are
72 * The default queue size limits are 5 buffers, 10MB of data, or
73 * two second worth of data, whichever is reached first. Note that the number
74 * of buffers will dynamically grow depending on the fill level of
77 * The #GstMultiQueue::underrun signal is emitted when all of the queues
78 * are empty. The #GstMultiQueue::overrun signal is emitted when one of the
80 * Both signals are emitted from the context of the streaming thread.
82 * When using #GstMultiQueue:sync-by-running-time the unlinked streams will
83 * be throttled by the highest running-time of linked streams. This allows
84 * further relinking of those unlinked streams without them being in the
85 * future (i.e. to achieve gapless playback).
86 * When dealing with streams which have got different consumption requirements
87 * downstream (ex: video decoders which will consume more buffer (in time) than
88 * audio decoders), it is recommended to group streams of the same type
89 * by using the pad "group-id" property. This will further throttle streams
90 * in time within that group.

335 * buffering_percent is used for determining if the fill level has reached
336 * the high watermark, and for producing BUFFERING messages. This value
337 * always uses a 0..100 range (since it is a percentage).
