9add348012 aggregator: Protect the tags with the object lock
The tags related variables were sometimes protected, sometimes not and
sometimes atomic. Put them all under the object lock.

90f3cb4af0 aggregator: Consistently lock some members
Some members sometimes used atomic access, sometimes where not locked at
all. Instead consistently use a mutex to protect them, also document
that.

3217e82791 aggregator: Replace event lock with pad's object lock
Reduce the number of locks simplify code, what is protects
is exposed, but the lock was not.

Also means adding an _unlocked version of gst_aggregator_pad_steal_buffer().

6379433a70 aggregator: Protect data with the same mutex as GCond
Whenever a GCond is used, the safest paradigm is to protect
the variable which change is signalled by the GCond with the same
mutex that the GCond depends on.

0db6fc999b aggregator: check if pads are ready more efficiently
No need to use an iterator for this which creates a temporary
structure every time and also involves taking and releasing the
object lock many times in the course of iterating. Not to mention
all that GList handling in gst_aggregator_iterate_sinkpads().

bbde713640 aggregator: Take the stream lock when iterating sink pads
When iterating sink pads to collect some data, we should take the stream lock so
we don't get stale data and possibly deadlock because of that. This fixes
a definitive deadlock in _wait_and_check() that manifests with high max
latencies in a live pipeline, and fixes other possible race conditions.

This simplifies the code and also makes sure that we don't forget to check all
conditions for waiting.

Also fix a potential deadlock caused by not checking if we're actually still
running before starting to wait.

f4b86a6d8c aggregator: make the src pad task drive the pipeline for live pipelines
This removes the uses of GAsyncQueue and replaces it with explicit
GMutex, GCond and wakeup count which is used for the non-live case.

For live pipelines, the aggregator waits on the clock until either
data arrives on all sink pads or the expected output buffer time
arrives plus the timeout/latency at which time, the subclass
produces a buffer.

0ad159dfb4 aggregator: Block serialized events/queries until the pad has consumed all buffers
Otherwise the caps of the pad might change while the subclass still works with
a buffer of the old caps, assuming the the current pad caps apply to that
buffer. Which then leads to crashes and other nice effects.

efdcc6c8eb aggregator: add a timeout property determining buffer wait time
Determines the amount of time that a pad will wait for a buffer before
being marked unresponsive.

Network sources may fail to produce buffers for an extended period of time,
currently causing the pipeline to stall possibly indefinitely, waiting for
these buffers to appear.

Subclasses should render unresponsive pads with either silence (audio), the
last (video) frame or what makes the most sense in the given context.

e8c34afd5f aggregator: Replace GMainContext with GAsyncQueue (v2)
The previous implementation kept accumulating GSources,
slowing down the iteration and leaking memory.

Instead of trying to fix the main context flushing, replace
it with a GAsyncQueue which is simple to flush and has
less overhead.

39e21bb6dd baseparse: fix taglist update spam
We would constantly re-post the taglist because
posted_avg_rate only gets set to avg_bitrate if
parse->priv->post_avg_bitrate is true, so if it's
false the posted rate will always differ from the
current average rate and we'd queue an update,
which leads to us spamming downstream and the
application with taglist updates.

Fix this by only queuing an update if the average
rate will actually be posted.

These taglists updates could cause expensive
operations on the application side, e.g. in Totem.

523de1a9dc basesrc: Don't hold LIVE_LOCK in create/alloc/fill
Holding this lock on live source prevents the source from changing
the caps in ::create() without risking a deadlock. This has consequences
as the LIVE_LOCK was replacing the STREAM_LOCK in many situation. As a
side effect:

- We no longer need to unlock when doing play/pause as the LIVE_LOCK
  isn't held. We then let the create() call finish, but will block if
  the state have changed meanwhile. This has the benefit that
  wait_preroll() calls in subclass is no longer needed.
- We no longer need to change the state to unlock, simplifying the
  set_flushing() interface
- We need different handling for EOS depending if we are in push or pull
  mode.

This patch also document the locking of each private class member and
the locking order.

daa98fc02a gst: Don't ref_sink() GstObject subclasses in instance_init/constructor
This is something bindings can't handle and it causes leaks. Instead
move the ref_sink() to the explicit, new() constructors.

This means that abstract classes, and anything that can have subclasses,
will have to do ref_sink() in their new() function now. Specifically
this affects GstClock and GstControlSource.

519d64881f Don't use deprecated g_object_newv()
Use g_object_new() instead which nowadays has a shortcut for the
no-properties check. It still does an extra GType check in the
function guard, but there's a pending patch to remove that
and it's hardly going to be a performance issue in practice,
even less so on a system that's compiled without run-time checks.

Alternative would be to move to the new g_object_new_properties()
with a fallback define for older glib versions, but it makes the
code look more unwieldy and doesn't seem worth it.

Fixes deprecation warnings when building against newer GLib versions.

If parsing returns a non-OK flow return in the middle

return not-linked in the middle, and then discard
subsequent data without pushing while returning OK.

A later success doesn't invalidate the earlier failure,
but we should continue processing after not-linked, so
as to keep parse state consistent.

baseparse would pass whatever is left in the adapter to the

discard that data then. The original intention of that code
seems to have been that if we have more data available than
the minimum required we should pass all of the data available
and not just the minimum required, which does make sense, so
we'll continue to do that in the case that more data is available.

b9a4a2a952 basesink: Update start time when losing state only if we were in PLAYING
If we were in PAUSED, the current clock time and base time don't have much to
do with the running time anymore as the clock might have advanced while we
were PAUSED. The system clock does that for example, audio clocks often don't.

Updating the start time in PAUSED will cause a) the wrong position to be
reported, b) step events to step not just the requested amount but the amount
of time we spent in PAUSED. The start time should only ever be updated when
going from PLAYING to PAUSED to remember the current running time (to be able
to compensate later when going to PLAYING for the clock time advancing while
PAUSED), not when we are already in PAUSED.

Based on a patch by Kishore Arepalli <kishore.arepalli@gmail.com>

The updating of the start time when the state is lost was added in commit
ba943a82c0 to fix the position reporting when
the state is lost. This still works correctly after this change.

If we don't store the value in prev_dts, we would over and over again
initialize the DTS from the last known upstream PTS. If upstream only provides
PTS every now and then, then this causes DTS to be rather static.

For example in adaptive streaming scenarios this means that all buffers in a
fragment will have exactly the same DTS while the PTS is properly updated. As
our queues are now preferring to do buffer fill level calculations on DTS,
this is causing huge problems there.

87c0513569 baseparse: Recheck after pre_push_frame() if there are tags pending
Many parsers are storing tags only in pre_push_frame(), if we wouldn't check
afterwards we would push buffers before those tags and a lot of code assumes that
tags are available before preroll.

78a832ebd5 baseparse: fix stray discont flag set on outgoing buffers in push mode
We have no guarantees about what flags are set on buffers we take
out of the GstAdapter. If we push out multiple buffers from the
first input buffer (which will have discont set), only the first
buffer we push out should be flagged as discont, not all of the
buffers produced from that first initial input buffer.

Fixes issue where the first few mp3 frames/seconds of data in push
mode were skipped or garbled in some cases, and the discont flags
would also trip up decoders which were getting drained/flushed for
every buffer. This was a regression introduced in 1.6 apparently.

Watching videos with variant bitrate is common to have delta

Instead of relying on fixed 10 kpbs delta, it is better to

there are headers in the middle of the stream and this patch

971ac61c36 baseparse: do not overwrite header buffer timestamps
baseparse tries to preserve timestamps from upstream if
it is running on a time segment and write that to
output buffers. It assumes the first DTS is going to be
segment.start and sets that to the first buffers. In case
the buffer is a header buffer, it had no timestamps and
will have only the DTS set due to this mechanism.

This patch prevents this by skipping this behavior for
header buffers.

2534e39e55 basetransform: Reconfigure before propose_allocation
There exist cases where a reconfigure event was propagated from

reconfigure only when the next buffer arrives. The problem is that
due to the allocation query being cached, the return query parameters
endup outdated.

In this patch we refactor the reconfigurating code into a function, and
along with reconfiguring when a new buffer comes in, we also reconfigure
when a query allocation arrives.

a887d81bfa baseparse: avoid tag list spam if upstream provides bitrate tags already
Explicitly keep track again whether upstream tags or parser tags
already contain bitrate information, and only force a tag update
for a bitrate if we are actually going to add the bitrate to the
taglist later. This fixes constant re-sending of the same taglist,
because upstream provided a bitrate already and we didn't add it,
so we didn't save the 'posted' bitrate, which would then in turn
again trigger the 'bitrate has changed too much, update tags'
code path. Fixes tag spam with m4a files for example.

4ec358773a baseparse: fix tag handling
In 0.10 there were no sticky events, and all tag events
sent would just be merged with the previously-received
tags. In 1.x we have sticky events, and the tags in the
tag event(s) should at all times carry the complete tags,
so we can't just push some tags and then just push tags
with just bitrates to update the bitrates, etc.

Instead we need to keep track of the upstream stream tags
received, of the tags set by the video decoder subclass,
and send an updated tag event with the combined tags
including our own bitrate tags (if applicable) whenever
the upstream tags, the subclass tags or any of our bitrates
change.

organize the flags setting and reset.

6240b03085 Revert "basesrc: fix pool leak on allocation query error path"
This reverts commit 84fdf50b2f.

It seems the bug was fixed independently, and the merge was
automagic, yielding two extra free calls.

7d3d4503a1 basesrc: Only set DTS to segment.start on the first buffer if subclass did not provide PTS
Otherwise we're going to set a rather arbitrary DTS of segment.start (usually
0) for live sources, which confuses synchronization if the source started
capturing at a later time. And it's especially wrong for raw media, for which
we should not set any DTS at all.

a041d8862d baseparse: only post 'no valid frames' error if buffers were received
Otherwise baseparse will consider empty streams to be an error while
an empty stream is a valid scenario. With this patch, errors would
only be emitted if the parser received data but wasn't able to
produce any output from it.

This change is only for push-mode operation as in pull mode an
empty file can be considered an error for the one driving the
pipeline

Includes a unit test for it

780f71c4d5 baseparse: reset skip on segments and discontinuities
Large scale skip is an optimization, and thus it is safer to
stop skipping than to continue. Clear skip on segments and
discontinuities, as these are points where it is possible that
the original idea of "bytes to skip" changes.
