eaf9ca90c7 decodebin2: Handle flushing with multiple decode groups
When an upstream element wants to flush downstream, we need to take
all chains/groups into consideration.

To that effect, when a FLUSH_START event is seen, after having it
sent downstream we mark all those chains/groups as "drained" (as if
they had seen a EOS event on the endpads).

When a FLUSH_STOP event is received, we check if we need to switch groups.
This is done by checking if there are next groups. If so, we will switch
over to the latest next_group. The actual switch will be done when
that group is blocked.

2d3743e37d decodebin2: Forward event/queries for unlinked groups
When upstream events/queries reach sinkpads of unlinked groups (i.e.
no longer linked to the upstream demuxer), this patch attempts to find
the linked group and forward it upstream of that group.

This is done by adding upstream event/query probes on new group sinkpads
and then:
* Checking if the pad is linked or not (has a peer or not)
* If there is a peer, just let the event/query follow through normally
* If there is no peer, we find a pad to which to proxy it and return
  GST_PROBE_HANDLED if it succeeded (allowing the event/query to be properly
  returned to the initial called)

Note that this is definitely not thread-safe for the time being

9c2e08c54d decodebin: only try to expose complete groups
When switching to a new chain it might be that this new chain
is not yet ready to be exposed so check it before exposing.

Can happen with mpegts that might delay adding pads or pushing data
until it has found the PMT/PAT/PCR and that may take a while depending
on the stream.

It happened frequently with HLS:

f99a24f8b3 playsink: Require the streamvolume interface on the sink when using the sink's volume/mute properties
If the sink has properties named volume and mute, we have no idea about their
meaning. The streamvolume interface standardizes the meaning.

In the case of osxaudiosink for example, the current volume property has a
range of 0.0 to 1.0, but we need 0.0 to 10.0 or similar. Also osxaudiosink
has no mute property. As such, the volume element should be used here instead.

ca864ce46e playbin: Fix some warnings with clang around multiview enums
There is the GstVideoMultiviewMode enum and the
GstVideoMultiviewFramePacking, which is a subset of the

types from the full enum. Do some casts and use the right

7b78a33dc6 playsink: fix the channel of color balance element
When traversing the color balance element channel list to find the one that
matches with the playsink proxy, the assignation was set to iterator of the
playsink proxy, not the balance element. Thus, the mapping to the values of
the balance element channel was wrong.

This patch fixes the assignation of the color balance element channel, so the
mapping to the channel of the color balance element is fixed.

50beddd474 playsink: cannot enable text flag while playing
when text playbin is not enabled in the beginning, then
video_srcpad_stream_synchronizer gets linked to videochain->sinkpad
and when we try to enable text bin during play, since it is already linked to videochain,
text chain does not get linked properly. Hence unlinking the same
before linking to text chain

12ac087807 playsink: use queue to avoid lock in audiotee audio branches
This part of pipeline is:

tee name=t ! visualizationbin ! streamsynchronizer name=s
t. ! s.

streamsynchronizer might block and it could starve the visualization
branch of the pipeline when it is enabled.

The visualization bin has queues internally but the other branch
that links the audiotee directly to the synchronizer is vulnerable
to block. Adding a queue between "t. ! s." fixes deadlocks.

Upstream might want to use it to properly map timestamps to running/stream
times, if we just override it with 0 synchronization will be just wrong.

For this we remove some old 0.10 code related to segment accumulation, and
remove some more code that is useless now, and accumulate the group start time
(aka segment.base offset) manually now.

d54d51d0d2 playbin: ignore new pads if it is shutting down
If a new pad is added after playbin has been put to READY/NULL it
should ignore new pads as it is shutting down.

This can happen when the pipeline fails to preroll (is still in READY)
and the user gives up on waiting or an error that doesn't reach
the demuxer occurs (on some event handling) and it will continue to
work and exposing pads while playbin has been put to NULL.

Without this check an input-selector is created and set to PAUSED
state, preventing playbin from properly shutting down in case it
has data blocked inside it.

This fixes a race where the use-buffering property on a multiqueue was

lower playback limits. This resulted in buffering messages being emitted

a2ee84fa80 decodebin: fix deadlock between downward state change and pad addition
If caps on a newly added pad are NULL, analyze_new_pad will try to
acquire the chain lock to add a probe to the pad so the chain can
be built later. This comes from the streaming thread, in response
to headers or other buffers causing this pad to be added, so the
stream lock is taken.

Meanwhile, another thread might be destroying the chain from a
downward state change. This will cause the chain to be freed with
the chain lock taken, and some elements are set to NULL here, which
can include the parser. This causes pad deactivation, which tries
to take the element's pad's stream lock, deadlocking.

Fix this by keeping track of which elements need setting to NULL,
and only do this after the chain lock is released. Only the chain
manipulation needs to be locked, not the elements' state changes.
