5216322d39 fdsink: Block in preroll_wait on unlock
The correct behaviour of anything stuck in the ->render() function
between ->unlock() and ->unlock_stop() is to call
gst_base_sink_wait_preroll() and only return an error if this returns an
error, otherwise, it must continue where it left off!

fa3eac2d28 multiqueue: Make sure not-linked streams get woken up
When running in sync-by-running-time mode, pad groups
that have exactly 1 pad and it's not-linked might never
wake up after computing a high time, as the per-pad-group
high time was only recomputed when a pad in the group
advances.

Wake those up using the global multiqueue high-time across
all other groups instead.

d03bd54780 queue: Fix race when calculating cur_level.time
On the first buffer, it's possible that sink_segment is set but
src_segment has not been set yet. If this is the case, we should not
calculate cur_level.time since sink_segment.position may be large and
src_segment.position default is 0, with the resulting diff being larger
than max-size-time, causing the queue to start leaking (if
leaky=downstream).

One potential consequence of this is that the segment event may be
stored on the srcpad before the caps event is pushed downstream, causing
a g_warning ("Sticky event misordering, got 'segment' before 'caps'").

67874ea86d multiqueue: Distinguish between buffering percentage and buffering level
To make the code clearer, and to facilitate future improvements, introduce
a distinction between the buffering level and the buffering percentage.

Buffering level: the queue's current fill level. The low/high watermarks
are in this range.

Buffering percentage: percentage relative to the low/high watermarks
(0% = low watermark, 100% = high watermark).

To that end, get_percentage() is renamed to get_buffering_level(). Also,
low/high_percent are renamed to low/high_watermark to avoid confusion.
mq->buffering_percent values are now normalized in the 0..100 range for
buffering messages inside update_buffering(), and not just before sending
the buffering message. Finally the buffering level range is parameterized
by adding a new constant called MAX_BUFFERING_LEVEL.

3117525cb6 multiqueue: Fix high_time wakeup logic
When calculating the high_time, cache the group value in each singlequeue.

This fixes the issue by which wake_up_next_non_linked() would use the global
high-time to decide whether to wake-up a waiting thread, instead of the group
one, resulting in those threads constantly spinning.

Tidy up a bit the waiting logic while we're at it.

With this patch, we go from 212% playing a 8 audio / 8 video file down to less
than 10% (most of it being the video decoding).

5154dcfbdc queue2: Post buffering messages earlier in ringbuffer mode
In ringbuffer mode we need to make sure we post buffering messages *before*
blocking to wait for data to be drained.

Without this, we would end up in situations like this:
* pipeline is pre-rolling
* Downstream demuxer/decoder has pushed data to all sinks, and demuxer thread
  is blocking downstream (i.e. not pulling from upstream/queue2).
* Therefore pipeline has pre-rolled ...
* ... but queue2 hasn't filled up yet, therefore the application waits for
  the buffering 100% messages before setting the pipeline to PLAYING
* But queue2 can't post that message, since the 100% message will be posted
  *after* there is room available for that last buffer.

1ff80fbf52 queue2: Fix average input rate calculation on small input range
When dealing with small-ish input data coming into queue2, such as
adaptivedemux fragments, we would never take into account the last
<200ms of data coming in.

The problem is that usually on TCP connection the download rate
gradually increases (i.e. the rate is lower at the beginning of a
download than it is later on). Combined with small download time (less
than a second) we would end up with a computed average input rate
which was sometimes up to 30-50% off from the *actual* average input
rate for that fragment.

In order to fix this, force the average input rate calculation when
we receive an EOS so that we take into account that final window
of data.

530001661d multiqueue: Fix behaviour with not-linked and eos pads
This is an update on c9b6848885
multiqueue: Fix not-linked pad handling at EOS

While that commit did fix the behaviour if upstream sent a GST_EVENT_EOS,
it would break the same issue when *downstream* returns GST_FLOW_EOS
(which can happen for example when downstream decoders receive data
from after the segment stop).

GST_PAD_IS_EOS() is only TRUE when a GST_EVENT_EOS has flown through it
and not when a GST_EVENT_EOS has gone through it.

In order to handle both cases, also take into account the last flow
return.

f4ba43b15d multiqueue: Add a pad property to "group" streams
When syncing by running time, multiqueue will throttle unlinked streams
based on a global "high-time" and the pending "next_time" of a stream.

The idea is that we don't want unlinked streams to be "behind" the global
running time of linked streams, so that if/when they get linked (like when
switching tracks) decoding/playback can resume from the same position as
the other streams.

The problem is that it assumes elements downstream will have a more or less
equal buffering/latency ... which isn't the case for streams of different
type. Video decoders tend to have higher latency (and therefore consume more
from upstream to output a given decoded frame) compared to audio ones, resulting
in the computed "high_time" being at the position of the video stream,
much further than the audio streams.

This means the unlinked audio streams end up being quite a bit after the linked
audio streams, resulting in gaps when switching streams.

In order to mitigate this issue, this patch adds a new "group-id" pad property
which allows users to "group" streams together. Calculating the high-time will
now be done not only globally, but also per group. This ensures that within
a given group unlinked streams will be throttled by that group's high-time
instead.

This fixes gaps when switching downstream elements (like switching audio tracks).

a1d2f387c6 multiqueue: Recalculate fill level after changing high-threshold
This ensures the following special case is handled properly:

1. Queue is empty
2. Data is pushed, fill level is below the current high-threshold
3. high-threshold is set to a level that is below the current fill level

Since mq->percent wasn't being recalculated in step #3 properly, this
caused the multiqueue to switch off its buffering state when new data is
pushed in, and never post a 100% buffering message. The application will
have received a <100% buffering message from step #2, but will never see
100%.

Fix this by recalculating the current fill level percentage during
high-threshold property changes in the same manner as it is done when
use-buffering is modified.

c9b6848885 multiqueue: Fix not-linked pad handling at EOS
Ensure that not-linked pads will drain out at EOS by
correctly detecting the EOS condition based on the EOS
pad flag (which indicates we actually pushed an EOS),
and make sure that not-linked pads are woken when doing
EOS processing on linked pads.

20859af3f2 typefind: Allow caps query in "have-type" signal handlers
If an application calls gst_pad_query_caps from its "have-type" signal handler,
then the query fails because typefind->caps has not been set yet.

This patch sets typefind->caps in the object method handler, before the signal
handlers are called.

a15fca1934 Revert "typefind: Store caps on the pad before emitting have-type but send it downstream only in the default signal handler"
This reverts commit 0835c3d656.

It causes deadlocks in decodebin, which currently would deadlock if the caps
are already on the pad in have-type and are forwarded while copying the sticky
events (while holding the decodebin lock)... as that might cause the next
element to expose pads, which then calls back into decodebin and takes the
decodebin lock.

This needs some more thoughts.

72c31876aa 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)

f468eb7db0 filesink: continue element cleanup even if fclose fails
Sometimes filesink cleanup during stop may fail due to fclose error.
In this case object left partial cleanup with no file opened
but still holding old file descriptor.

It's not possible to change location property in a such state,
so next start will cause old file overwrite if 'append' does not set.

According to man page and POSIX standard about fclose behavior(extract):
------------------------------------------------------------------------
The fclose() function shall cause the stream pointed to by stream
to be flushed and the associated file to be closed.
...
Whether or not the call succeeds, the stream shall be disassociated
from the file and any buffer set by the setbuf() or setvbuf()
function shall be disassociated from the stream.
...
The fclose() function shall perform the equivalent of a close()
on the file descriptor that is associated with the stream
pointed to by stream.

After the call to fclose(), any use of stream results
in undefined behavior.
------------------------------------------------------------------------

So file is in 'closed' state no matter if fclose succeed or not.
And cleanup could be continued.

7c8f76a39f multiqueue: Improve incoming SEGMENT handling
Previously this code was just blindly setting the cached flow return
of downstream to GST_FLOW_OK when we get a SEGMENT.

The problem is that this can not be done blindly. If downstream was
not linked, the corresponding sinqlequeue source pad thread might be
waiting for the next ID to be woken up upon.

By blindly setting the cached return value to GST_FLOW_OK, and if that
stream was the only one that was NOT_LINKED, then the next time we
check (from any other thread) to see if we need to wake up a source pad
thread ... we won't even try, because none of the cached flow return
are equal to GST_FLOW_NOT_LINKED.

This would result in that thread never being woken up

6f24f4917d input-selector: Use segment-presence for running_time check
When determining whether the running_time of a pad can be
calculated, check if the segment is in TIME format instead
of using the 'active' field.

Since the latter is set through *any* activity, it's not a
reliable indicator of segment presence.

0a3ded1932 input-selector: Remove 'blocked' flag
With the disappearance of the 'block' signal, this
flag cannot be set to TRUE.

gst_input_selector_wait disappears as it never waits
and just returns self->flushing.

7a1ebbe0e3 input-selector: Remove obsolete 'block' signal
This signal blocks the input-selector with no means of unblocking
other than a state change back to READY. It seems this signal was
part of an old way of synchronously switching the selector,
together with the already-removed 'switch' signal.

Removing the signal is safe, as attempting to use it could only
end in deadlocks. Attempting to emit an unknown signal just causes
g_criticals.

ce663311e1 input-selector: Fix waiting on EOS
This apparently got broken by bc1ec4e. Since self->blocked is always
FALSE, gst_input_selector_wait never actually waits.

Using (!self->eos || self->blocked) && ... as the loop condition would
be incorrect as well, because then the other call to the function in
_chain would block until EOS, so the functions cannot be merged trivially.

Since blocking is obsolete, gst_input_selector_wait will get removed anyway.
As such, just inline the loop.

7b0b93dafe queue2: Process SEEKING query
Add QUERY_SEEKING handling to queue2, so RTMP live streams become
seekable when a queue2 in download or ringbuffer mode is inserted:

rtmpsrc ! queue2 ! flvdemux

6a6188a82f valve: Don't drop non-serialized queries when the valve is dropping
Otherwise we end up dropping e.g. CAPS queries, and then upstream just
negotiates to whatever format it wants to. Once the valve is not-dropping
anymore this can easily result in negotiation failing completely.

Demultiplex a stream to multiple source pads based on the stream ids from the
stream-start events. This basically reverses the behaviour of funnel.
