/**
* SECTION:element-multiqueue
* @title: multiqueue
* @see_also: #GstQueue
*
* Multiqueue is similar to a normal #GstQueue with the following additional
* features:
*
* 1) Multiple streamhandling
*
* * The element handles queueing data on more than one stream at once. To
* achieve such a feature it has request sink pads (sink%u) and
* 'sometimes' src pads (src%u). When requesting a given sinkpad with gst_element_request_pad(),
* the associated srcpad for that stream will be created.
* Example: requesting sink1 will generate src1.
*
* 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
* stream. If an EOS event comes through a srcpad, the associated queue will be
* considered as 'not-empty' in the queue-size-growing algorithm.
*
* 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.

multiqueue: Optimize multiqueue sizes based on interleave Multiqueue should only be used to cope with: * decoupling upstream and dowstream threading (i.e. having separate threads for elementary streams). * Ensuring individual queues have enough space to cope with upstream interleave (distance in stream time between co-located samples). This is to guarantee that we have enough room in each individual queues to provide new data in each, without being blocked. * Limit the queue sizes to that interleave distance (and an extra minimal buffering size). This is to ensure we don't consume too much memory. Based on that, multiqueue now continuously calculates the input interleave (per incoming streaming thread). Based on that, it calculates a target interleave (currently 1.5 x real_interleave + 250ms padding). If the target interleave is greater than the current max_size.time, it will update it accordingly (to allow enough margin to not block). If the target interleave goes down by more than 50%, we re-adjust it once we know we have gone past a safe distance (2 x current max_size.time). This mode can only be used for incoming streams that are guaranteed to be properly timestamped. Furthermore, we ignore sparse streams when calculating interleave and maximum size of queues. For the simplest of use-cases (single stream), multiqueue acts as a single queue with a time limit of 250ms. If there are multiple inputs, but each come from a different streaming thread, the maximum time limit will also end up being 250ms. On regular files (more than one input stream from the same upstream streaming thread), it can reduce the total memory used as much as 10x, ending up with max_size.time around 500ms. Due to the adaptive nature, it can also cope with changing interleave (which can happen commonly on some files at startup/pre-roll time)

This gives more accurate results and can compensate for segments correctly. Make a queue by default only 5 buffers deep. We will now increase the buffer size depending on the filledness of the other queues. Factor out commong flush code. Make sure we don't add additional refcounts to buffers when we can avoid it. Propagate GstFlowReturn differently. Use GSlice for intermediate GstMultiQueueItems. Keep track of EOS. Resize queues on over and underruns based on filled level of other queues. When checking if the queue is filled, prefer to measure in time if we can and fall back to bytes when no time is known. * plugins/elements/gstqueue.c: Fix return value.

multiqueue: Optimize multiqueue sizes based on interleave Multiqueue should only be used to cope with: * decoupling upstream and dowstream threading (i.e. having separate threads for elementary streams). * Ensuring individual queues have enough space to cope with upstream interleave (distance in stream time between co-located samples). This is to guarantee that we have enough room in each individual queues to provide new data in each, without being blocked. * Limit the queue sizes to that interleave distance (and an extra minimal buffering size). This is to ensure we don't consume too much memory. Based on that, multiqueue now continuously calculates the input interleave (per incoming streaming thread). Based on that, it calculates a target interleave (currently 1.5 x real_interleave + 250ms padding). If the target interleave is greater than the current max_size.time, it will update it accordingly (to allow enough margin to not block). If the target interleave goes down by more than 50%, we re-adjust it once we know we have gone past a safe distance (2 x current max_size.time). This mode can only be used for incoming streams that are guaranteed to be properly timestamped. Furthermore, we ignore sparse streams when calculating interleave and maximum size of queues. For the simplest of use-cases (single stream), multiqueue acts as a single queue with a time limit of 250ms. If there are multiple inputs, but each come from a different streaming thread, the maximum time limit will also end up being 250ms. On regular files (more than one input stream from the same upstream streaming thread), it can reduce the total memory used as much as 10x, ending up with max_size.time around 500ms. Due to the adaptive nature, it can also cope with changing interleave (which can happen commonly on some files at startup/pre-roll time)

If there are multiple inputs, but each come from a different streaming thread, the maximum time limit will also end up being 250ms. On regular files (more than one input stream from the same upstream streaming thread), it can reduce the total memory used as much as 10x, ending up with max_size.time around 500ms. Due to the adaptive nature, it can also cope with changing interleave (which can happen commonly on some files at startup/pre-roll time)

/* Explanation for buffer levels and percentages:
*
* The buffering_level functions here return a value in a normalized range
* that specifies the current fill level of a queue. The range goes from 0 to
* MAX_BUFFERING_LEVEL. The low/high watermarks also use this same range.
*
* This is not to be confused with the buffering_percent value, which is
* a *relative* quantity - relative to the low/high watermarks.
* 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
* percentage value that is relative to the low/high watermark. */

This gives more accurate results and can compensate for segments correctly. Make a queue by default only 5 buffers deep. We will now increase the buffer size depending on the filledness of the other queues. Factor out commong flush code. Make sure we don't add additional refcounts to buffers when we can avoid it. Propagate GstFlowReturn differently. Use GSlice for intermediate GstMultiQueueItems. Keep track of EOS. Resize queues on over and underruns based on filled level of other queues. When checking if the queue is filled, prefer to measure in time if we can and fall back to bytes when no time is known. * plugins/elements/gstqueue.c: Fix return value.

multiqueue: Optimize multiqueue sizes based on interleave Multiqueue should only be used to cope with: * decoupling upstream and dowstream threading (i.e. having separate threads for elementary streams). * Ensuring individual queues have enough space to cope with upstream interleave (distance in stream time between co-located samples). This is to guarantee that we have enough room in each individual queues to provide new data in each, without being blocked. * Limit the queue sizes to that interleave distance (and an extra minimal buffering size). This is to ensure we don't consume too much memory. Based on that, multiqueue now continuously calculates the input interleave (per incoming streaming thread). Based on that, it calculates a target interleave (currently 1.5 x real_interleave + 250ms padding). If the target interleave is greater than the current max_size.time, it will update it accordingly (to allow enough margin to not block). If the target interleave goes down by more than 50%, we re-adjust it once we know we have gone past a safe distance (2 x current max_size.time). This mode can only be used for incoming streams that are guaranteed to be properly timestamped. Furthermore, we ignore sparse streams when calculating interleave and maximum size of queues. For the simplest of use-cases (single stream), multiqueue acts as a single queue with a time limit of 250ms. If there are multiple inputs, but each come from a different streaming thread, the maximum time limit will also end up being 250ms. On regular files (more than one input stream from the same upstream streaming thread), it can reduce the total memory used as much as 10x, ending up with max_size.time around 500ms. Due to the adaptive nature, it can also cope with changing interleave (which can happen commonly on some files at startup/pre-roll time)

This gives more accurate results and can compensate for segments correctly. Make a queue by default only 5 buffers deep. We will now increase the buffer size depending on the filledness of the other queues. Factor out commong flush code. Make sure we don't add additional refcounts to buffers when we can avoid it. Propagate GstFlowReturn differently. Use GSlice for intermediate GstMultiQueueItems. Keep track of EOS. Resize queues on over and underruns based on filled level of other queues. When checking if the queue is filled, prefer to measure in time if we can and fall back to bytes when no time is known. * plugins/elements/gstqueue.c: Fix return value.

multiqueue: Optimize multiqueue sizes based on interleave Multiqueue should only be used to cope with: * decoupling upstream and dowstream threading (i.e. having separate threads for elementary streams). * Ensuring individual queues have enough space to cope with upstream interleave (distance in stream time between co-located samples). This is to guarantee that we have enough room in each individual queues to provide new data in each, without being blocked. * Limit the queue sizes to that interleave distance (and an extra minimal buffering size). This is to ensure we don't consume too much memory. Based on that, multiqueue now continuously calculates the input interleave (per incoming streaming thread). Based on that, it calculates a target interleave (currently 1.5 x real_interleave + 250ms padding). If the target interleave is greater than the current max_size.time, it will update it accordingly (to allow enough margin to not block). If the target interleave goes down by more than 50%, we re-adjust it once we know we have gone past a safe distance (2 x current max_size.time). This mode can only be used for incoming streams that are guaranteed to be properly timestamped. Furthermore, we ignore sparse streams when calculating interleave and maximum size of queues. For the simplest of use-cases (single stream), multiqueue acts as a single queue with a time limit of 250ms. If there are multiple inputs, but each come from a different streaming thread, the maximum time limit will also end up being 250ms. On regular files (more than one input stream from the same upstream streaming thread), it can reduce the total memory used as much as 10x, ending up with max_size.time around 500ms. Due to the adaptive nature, it can also cope with changing interleave (which can happen commonly on some files at startup/pre-roll time)

multiqueue: Optimize multiqueue sizes based on interleave Multiqueue should only be used to cope with: * decoupling upstream and dowstream threading (i.e. having separate threads for elementary streams). * Ensuring individual queues have enough space to cope with upstream interleave (distance in stream time between co-located samples). This is to guarantee that we have enough room in each individual queues to provide new data in each, without being blocked. * Limit the queue sizes to that interleave distance (and an extra minimal buffering size). This is to ensure we don't consume too much memory. Based on that, multiqueue now continuously calculates the input interleave (per incoming streaming thread). Based on that, it calculates a target interleave (currently 1.5 x real_interleave + 250ms padding). If the target interleave is greater than the current max_size.time, it will update it accordingly (to allow enough margin to not block). If the target interleave goes down by more than 50%, we re-adjust it once we know we have gone past a safe distance (2 x current max_size.time). This mode can only be used for incoming streams that are guaranteed to be properly timestamped. Furthermore, we ignore sparse streams when calculating interleave and maximum size of queues. For the simplest of use-cases (single stream), multiqueue acts as a single queue with a time limit of 250ms. If there are multiple inputs, but each come from a different streaming thread, the maximum time limit will also end up being 250ms. On regular files (more than one input stream from the same upstream streaming thread), it can reduce the total memory used as much as 10x, ending up with max_size.time around 500ms. Due to the adaptive nature, it can also cope with changing interleave (which can happen commonly on some files at startup/pre-roll time)

multiqueue: Not post BUFFERING message if one of the singlequeue doesn't need it Imagine the following 'pipeline' -------------- p1/| 'fullqueue' |--- 'laggy' downstream --------- / | | -| demuxer | | multiqueue | --------- \ | | p2\| 'emptyqueue' |--- 'fast' downstream -------------- In the case downstream of one single queue (fullqueue) has (a lot of) latency (for example for reverse playback with video), we can end up having the other SingleQueue (emptyqueue) emptied, before that fullqueue gets unblocked. In the meantime, the demuxer tries to push on fullqueue, and is blocking there. In that case the current code will post a BUFFERING message on the bus when emptyqueue gets emptied, that leads to the application setting the pipeline state to PAUSED. So now we end up in a situation where 'laggy downstream' is prerolled and will not unblock anymore because the pipeline is set to PAUSED, the fullequeue does not have a chance to be emptied and the emptyqueue can not get filled anymore so no more BUFERRING message will be posted and the pipeline is stucked in PAUSED for the eternity. Making sure that we do not try to "buffer" if one of the single queue does not need buffering, prevents this situtation from happening though it lets the oportunity for buffering in all other cases. That implements a new logic where we need all singlequeue to need buffering for the multiqueue to actually state buffering is needed, taking the maximum buffering of the single queue as the reference point. https://bugzilla.gnome.org/show_bug.cgi?id=734412

multiqueue: Optimize multiqueue sizes based on interleave Multiqueue should only be used to cope with: * decoupling upstream and dowstream threading (i.e. having separate threads for elementary streams). * Ensuring individual queues have enough space to cope with upstream interleave (distance in stream time between co-located samples). This is to guarantee that we have enough room in each individual queues to provide new data in each, without being blocked. * Limit the queue sizes to that interleave distance (and an extra minimal buffering size). This is to ensure we don't consume too much memory. Based on that, multiqueue now continuously calculates the input interleave (per incoming streaming thread). Based on that, it calculates a target interleave (currently 1.5 x real_interleave + 250ms padding). If the target interleave is greater than the current max_size.time, it will update it accordingly (to allow enough margin to not block). If the target interleave goes down by more than 50%, we re-adjust it once we know we have gone past a safe distance (2 x current max_size.time). This mode can only be used for incoming streams that are guaranteed to be properly timestamped. Furthermore, we ignore sparse streams when calculating interleave and maximum size of queues. For the simplest of use-cases (single stream), multiqueue acts as a single queue with a time limit of 250ms. If there are multiple inputs, but each come from a different streaming thread, the maximum time limit will also end up being 250ms. On regular files (more than one input stream from the same upstream streaming thread), it can reduce the total memory used as much as 10x, ending up with max_size.time around 500ms. Due to the adaptive nature, it can also cope with changing interleave (which can happen commonly on some files at startup/pre-roll time)

multiqueue: Optimize multiqueue sizes based on interleave Multiqueue should only be used to cope with: * decoupling upstream and dowstream threading (i.e. having separate threads for elementary streams). * Ensuring individual queues have enough space to cope with upstream interleave (distance in stream time between co-located samples). This is to guarantee that we have enough room in each individual queues to provide new data in each, without being blocked. * Limit the queue sizes to that interleave distance (and an extra minimal buffering size). This is to ensure we don't consume too much memory. Based on that, multiqueue now continuously calculates the input interleave (per incoming streaming thread). Based on that, it calculates a target interleave (currently 1.5 x real_interleave + 250ms padding). If the target interleave is greater than the current max_size.time, it will update it accordingly (to allow enough margin to not block). If the target interleave goes down by more than 50%, we re-adjust it once we know we have gone past a safe distance (2 x current max_size.time). This mode can only be used for incoming streams that are guaranteed to be properly timestamped. Furthermore, we ignore sparse streams when calculating interleave and maximum size of queues. For the simplest of use-cases (single stream), multiqueue acts as a single queue with a time limit of 250ms. If there are multiple inputs, but each come from a different streaming thread, the maximum time limit will also end up being 250ms.

multiqueue: Optimize multiqueue sizes based on interleave Multiqueue should only be used to cope with: * decoupling upstream and dowstream threading (i.e. having separate threads for elementary streams). * Ensuring individual queues have enough space to cope with upstream interleave (distance in stream time between co-located samples). This is to guarantee that we have enough room in each individual queues to provide new data in each, without being blocked. * Limit the queue sizes to that interleave distance (and an extra minimal buffering size). This is to ensure we don't consume too much memory. Based on that, multiqueue now continuously calculates the input interleave (per incoming streaming thread). Based on that, it calculates a target interleave (currently 1.5 x real_interleave + 250ms padding). If the target interleave is greater than the current max_size.time, it will update it accordingly (to allow enough margin to not block). If the target interleave goes down by more than 50%, we re-adjust it once we know we have gone past a safe distance (2 x current max_size.time). This mode can only be used for incoming streams that are guaranteed to be properly timestamped. Furthermore, we ignore sparse streams when calculating interleave and maximum size of queues. For the simplest of use-cases (single stream), multiqueue acts as a single queue with a time limit of 250ms. If there are multiple inputs, but each come from a different streaming thread, the maximum time limit will also end up being 250ms. On regular files (more than one input stream from the same upstream streaming thread), it can reduce the total memory used as much as 10x, ending up with max_size.time around 500ms. Due to the adaptive nature, it can also cope with changing interleave (which can happen commonly on some files at startup/pre-roll time)

multiqueue: Optimize multiqueue sizes based on interleave Multiqueue should only be used to cope with: * decoupling upstream and dowstream threading (i.e. having separate threads for elementary streams). * Ensuring individual queues have enough space to cope with upstream interleave (distance in stream time between co-located samples). This is to guarantee that we have enough room in each individual queues to provide new data in each, without being blocked. * Limit the queue sizes to that interleave distance (and an extra minimal buffering size). This is to ensure we don't consume too much memory. Based on that, multiqueue now continuously calculates the input interleave (per incoming streaming thread). Based on that, it calculates a target interleave (currently 1.5 x real_interleave + 250ms padding). If the target interleave is greater than the current max_size.time, it will update it accordingly (to allow enough margin to not block). If the target interleave goes down by more than 50%, we re-adjust it once we know we have gone past a safe distance (2 x current max_size.time). This mode can only be used for incoming streams that are guaranteed to be properly timestamped. Furthermore, we ignore sparse streams when calculating interleave and maximum size of queues. For the simplest of use-cases (single stream), multiqueue acts as a single queue with a time limit of 250ms. If there are multiple inputs, but each come from a different streaming thread, the maximum time limit will also end up being 250ms. On regular files (more than one input stream from the same upstream streaming thread), it can reduce the total memory used as much as 10x, ending up with max_size.time around 500ms. Due to the adaptive nature, it can also cope with changing interleave (which can happen commonly on some files at startup/pre-roll time)

This gives more accurate results and can compensate for segments correctly. Make a queue by default only 5 buffers deep. We will now increase the buffer size depending on the filledness of the other queues. Factor out commong flush code. Make sure we don't add additional refcounts to buffers when we can avoid it. Propagate GstFlowReturn differently. Use GSlice for intermediate GstMultiQueueItems. Keep track of EOS. Resize queues on over and underruns based on filled level of other queues. When checking if the queue is filled, prefer to measure in time if we can and fall back to bytes when no time is known. * plugins/elements/gstqueue.c: Fix return value.

Added methods to get the current levels and to inform the queue that the 'full' limits changed. * plugins/elements/gstmultiqueue.c: (gst_multi_queue_init), (gst_multi_queue_finalize), (gst_multi_queue_set_property), (gst_single_queue_flush), (update_time_level), (apply_segment), (apply_buffer), (gst_single_queue_push_one), (gst_multi_queue_item_steal_object), (gst_multi_queue_item_destroy), (gst_multi_queue_item_new), (gst_multi_queue_loop), (gst_multi_queue_chain), (gst_multi_queue_sink_activate_push), (gst_multi_queue_sink_event), (gst_multi_queue_getcaps), (gst_multi_queue_src_activate_push), (gst_multi_queue_src_query), (single_queue_overrun_cb), (single_queue_underrun_cb), (single_queue_check_full), (gst_single_queue_new): Keep track of time in the queue by measuring the difference between running_time on input and output. This gives more accurate results and can compensate for segments correctly. Make a queue by default only 5 buffers deep. We will now increase the buffer size depending on the filledness of the other queues. Factor out commong flush code. Make sure we don't add additional refcounts to buffers when we can avoid it. Propagate GstFlowReturn differently. Use GSlice for intermediate GstMultiQueueItems. Keep track of EOS. Resize queues on over and underruns based on filled level of other queues. When checking if the queue is filled, prefer to measure in time if we can and fall back to bytes when no time is known. * plugins/elements/gstqueue.c: Fix return value.

multiqueue: Optimize multiqueue sizes based on interleave Multiqueue should only be used to cope with: * decoupling upstream and dowstream threading (i.e. having separate threads for elementary streams). * Ensuring individual queues have enough space to cope with upstream interleave (distance in stream time between co-located samples). This is to guarantee that we have enough room in each individual queues to provide new data in each, without being blocked. * Limit the queue sizes to that interleave distance (and an extra minimal buffering size). This is to ensure we don't consume too much memory. Based on that, multiqueue now continuously calculates the input interleave (per incoming streaming thread). Based on that, it calculates a target interleave (currently 1.5 x real_interleave + 250ms padding). If the target interleave is greater than the current max_size.time, it will update it accordingly (to allow enough margin to not block). If the target interleave goes down by more than 50%, we re-adjust it once we know we have gone past a safe distance (2 x current max_size.time). This mode can only be used for incoming streams that are guaranteed to be properly timestamped. Furthermore, we ignore sparse streams when calculating interleave and maximum size of queues. For the simplest of use-cases (single stream), multiqueue acts as a single queue with a time limit of 250ms. If there are multiple inputs, but each come from a different streaming thread, the maximum time limit will also end up being 250ms. On regular files (more than one input stream from the same upstream streaming thread), it can reduce the total memory used as much as 10x, ending up with max_size.time around 500ms. Due to the adaptive nature, it can also cope with changing interleave (which can happen commonly on some files at startup/pre-roll time)

Added methods to get the current levels and to inform the queue that the 'full' limits changed. * plugins/elements/gstmultiqueue.c: (gst_multi_queue_init), (gst_multi_queue_finalize), (gst_multi_queue_set_property), (gst_single_queue_flush), (update_time_level), (apply_segment), (apply_buffer), (gst_single_queue_push_one), (gst_multi_queue_item_steal_object), (gst_multi_queue_item_destroy), (gst_multi_queue_item_new), (gst_multi_queue_loop), (gst_multi_queue_chain), (gst_multi_queue_sink_activate_push), (gst_multi_queue_sink_event), (gst_multi_queue_getcaps), (gst_multi_queue_src_activate_push), (gst_multi_queue_src_query), (single_queue_overrun_cb), (single_queue_underrun_cb), (single_queue_check_full), (gst_single_queue_new): Keep track of time in the queue by measuring the difference between running_time on input and output. This gives more accurate results and can compensate for segments correctly. Make a queue by default only 5 buffers deep. We will now increase the buffer size depending on the filledness of the other queues. Factor out commong flush code. Make sure we don't add additional refcounts to buffers when we can avoid it. Propagate GstFlowReturn differently. Use GSlice for intermediate GstMultiQueueItems. Keep track of EOS. Resize queues on over and underruns based on filled level of other queues. When checking if the queue is filled, prefer to measure in time if we can and fall back to bytes when no time is known. * plugins/elements/gstqueue.c: Fix return value.

multiqueue: Optimize multiqueue sizes based on interleave Multiqueue should only be used to cope with: * decoupling upstream and dowstream threading (i.e. having separate threads for elementary streams). * Ensuring individual queues have enough space to cope with upstream interleave (distance in stream time between co-located samples). This is to guarantee that we have enough room in each individual queues to provide new data in each, without being blocked. * Limit the queue sizes to that interleave distance (and an extra minimal buffering size). This is to ensure we don't consume too much memory. Based on that, multiqueue now continuously calculates the input interleave (per incoming streaming thread). Based on that, it calculates a target interleave (currently 1.5 x real_interleave + 250ms padding). If the target interleave is greater than the current max_size.time, it will update it accordingly (to allow enough margin to not block). If the target interleave goes down by more than 50%, we re-adjust it once we know we have gone past a safe distance (2 x current max_size.time). This mode can only be used for incoming streams that are guaranteed to be properly timestamped. Furthermore, we ignore sparse streams when calculating interleave and maximum size of queues. For the simplest of use-cases (single stream), multiqueue acts as a single queue with a time limit of 250ms. If there are multiple inputs, but each come from a different streaming thread, the maximum time limit will also end up being 250ms. On regular files (more than one input stream from the same upstream streaming thread), it can reduce the total memory used as much as 10x, ending up with max_size.time around 500ms. Due to the adaptive nature, it can also cope with changing interleave (which can happen commonly on some files at startup/pre-roll time)

multiqueue: Not post BUFFERING message if one of the singlequeue doesn't need it Imagine the following 'pipeline' -------------- p1/| 'fullqueue' |--- 'laggy' downstream --------- / | | -| demuxer | | multiqueue | --------- \ | | p2\| 'emptyqueue' |--- 'fast' downstream -------------- In the case downstream of one single queue (fullqueue) has (a lot of) latency (for example for reverse playback with video), we can end up having the other SingleQueue (emptyqueue) emptied, before that fullqueue gets unblocked. In the meantime, the demuxer tries to push on fullqueue, and is blocking there. In that case the current code will post a BUFFERING message on the bus when emptyqueue gets emptied, that leads to the application setting the pipeline state to PAUSED. So now we end up in a situation where 'laggy downstream' is prerolled and will not unblock anymore because the pipeline is set to PAUSED, the fullequeue does not have a chance to be emptied and the emptyqueue can not get filled anymore so no more BUFERRING message will be posted and the pipeline is stucked in PAUSED for the eternity. Making sure that we do not try to "buffer" if one of the single queue does not need buffering, prevents this situtation from happening though it lets the oportunity for buffering in all other cases. That implements a new logic where we need all singlequeue to need buffering for the multiqueue to actually state buffering is needed, taking the maximum buffering of the single queue as the reference point. https://bugzilla.gnome.org/show_bug.cgi?id=734412

multiqueue: Optimize multiqueue sizes based on interleave Multiqueue should only be used to cope with: * decoupling upstream and dowstream threading (i.e. having separate threads for elementary streams). * Ensuring individual queues have enough space to cope with upstream interleave (distance in stream time between co-located samples). This is to guarantee that we have enough room in each individual queues to provide new data in each, without being blocked. * Limit the queue sizes to that interleave distance (and an extra minimal buffering size). This is to ensure we don't consume too much memory. Based on that, multiqueue now continuously calculates the input interleave (per incoming streaming thread). Based on that, it calculates a target interleave (currently 1.5 x real_interleave + 250ms padding). If the target interleave is greater than the current max_size.time, it will update it accordingly (to allow enough margin to not block). If the target interleave goes down by more than 50%, we re-adjust it once we know we have gone past a safe distance (2 x current max_size.time). This mode can only be used for incoming streams that are guaranteed to be properly timestamped. Furthermore, we ignore sparse streams when calculating interleave and maximum size of queues. For the simplest of use-cases (single stream), multiqueue acts as a single queue with a time limit of 250ms. If there are multiple inputs, but each come from a different streaming thread, the maximum time limit will also end up being 250ms. On regular files (more than one input stream from the same upstream streaming thread), it can reduce the total memory used as much as 10x, ending up with max_size.time around 500ms. Due to the adaptive nature, it can also cope with changing interleave (which can happen commonly on some files at startup/pre-roll time)

Original commit message from CVS: * libs/gst/base/gstdataqueue.c: (gst_data_queue_cleanup), (gst_data_queue_finalize), (gst_data_queue_locked_is_empty), (gst_data_queue_set_flushing), (gst_data_queue_push), (gst_data_queue_pop), (gst_data_queue_drop_head), (gst_data_queue_limits_changed), (gst_data_queue_get_level): * libs/gst/base/gstdataqueue.h: Various cleanups. Added methods to get the current levels and to inform the queue that the 'full' limits changed. * plugins/elements/gstmultiqueue.c: (gst_multi_queue_init), (gst_multi_queue_finalize), (gst_multi_queue_set_property), (gst_single_queue_flush), (update_time_level), (apply_segment), (apply_buffer), (gst_single_queue_push_one), (gst_multi_queue_item_steal_object), (gst_multi_queue_item_destroy), (gst_multi_queue_item_new), (gst_multi_queue_loop), (gst_multi_queue_chain), (gst_multi_queue_sink_activate_push), (gst_multi_queue_sink_event), (gst_multi_queue_getcaps), (gst_multi_queue_src_activate_push), (gst_multi_queue_src_query), (single_queue_overrun_cb), (single_queue_underrun_cb), (single_queue_check_full), (gst_single_queue_new): Keep track of time in the queue by measuring the difference between running_time on input and output. This gives more accurate results and can compensate for segments correctly. Make a queue by default only 5 buffers deep. We will now increase the buffer size depending on the filledness of the other queues. Factor out commong flush code. Make sure we don't add additional refcounts to buffers when we can avoid it. Propagate GstFlowReturn differently. Use GSlice for intermediate GstMultiQueueItems. Keep track of EOS. Resize queues on over and underruns based on filled level of other queues. When checking if the queue is filled, prefer to measure in time if we can and fall back to bytes when no time is known. * plugins/elements/gstqueue.c: Fix return value.

This gives more accurate results and can compensate for segments correctly. Make a queue by default only 5 buffers deep. We will now increase the buffer size depending on the filledness of the other queues. Factor out commong flush code. Make sure we don't add additional refcounts to buffers when we can avoid it. Propagate GstFlowReturn differently. Use GSlice for intermediate GstMultiQueueItems. Keep track of EOS. Resize queues on over and underruns based on filled level of other queues. When checking if the queue is filled, prefer to measure in time if we can and fall back to bytes when no time is known. * plugins/elements/gstqueue.c: Fix return value.

multiqueue: Not post BUFFERING message if one of the singlequeue doesn't need it Imagine the following 'pipeline' -------------- p1/| 'fullqueue' |--- 'laggy' downstream --------- / | | -| demuxer | | multiqueue | --------- \ | | p2\| 'emptyqueue' |--- 'fast' downstream -------------- In the case downstream of one single queue (fullqueue) has (a lot of) latency (for example for reverse playback with video), we can end up having the other SingleQueue (emptyqueue) emptied, before that fullqueue gets unblocked. In the meantime, the demuxer tries to push on fullqueue, and is blocking there. In that case the current code will post a BUFFERING message on the bus when emptyqueue gets emptied, that leads to the application setting the pipeline state to PAUSED. So now we end up in a situation where 'laggy downstream' is prerolled and will not unblock anymore because the pipeline is set to PAUSED, the fullequeue does not have a chance to be emptied and the emptyqueue can not get filled anymore so no more BUFERRING message will be posted and the pipeline is stucked in PAUSED for the eternity. Making sure that we do not try to "buffer" if one of the single queue does not need buffering, prevents this situtation from happening though it lets the oportunity for buffering in all other cases. That implements a new logic where we need all singlequeue to need buffering for the multiqueue to actually state buffering is needed, taking the maximum buffering of the single queue as the reference point. https://bugzilla.gnome.org/show_bug.cgi?id=734412

multiqueue: Optimize multiqueue sizes based on interleave Multiqueue should only be used to cope with: * decoupling upstream and dowstream threading (i.e. having separate threads for elementary streams). * Ensuring individual queues have enough space to cope with upstream interleave (distance in stream time between co-located samples). This is to guarantee that we have enough room in each individual queues to provide new data in each, without being blocked. * Limit the queue sizes to that interleave distance (and an extra minimal buffering size). This is to ensure we don't consume too much memory. Based on that, multiqueue now continuously calculates the input interleave (per incoming streaming thread). Based on that, it calculates a target interleave (currently 1.5 x real_interleave + 250ms padding). If the target interleave is greater than the current max_size.time, it will update it accordingly (to allow enough margin to not block). If the target interleave goes down by more than 50%, we re-adjust it once we know we have gone past a safe distance (2 x current max_size.time). This mode can only be used for incoming streams that are guaranteed to be properly timestamped. Furthermore, we ignore sparse streams when calculating interleave and maximum size of queues. For the simplest of use-cases (single stream), multiqueue acts as a single queue with a time limit of 250ms. If there are multiple inputs, but each come from a different streaming thread, the maximum time limit will also end up being 250ms. On regular files (more than one input stream from the same upstream streaming thread), it can reduce the total memory used as much as 10x, ending up with max_size.time around 500ms. Due to the adaptive nature, it can also cope with changing interleave (which can happen commonly on some files at startup/pre-roll time)
