eacb7a77d2 playbin3: Re-enable buffering message handling
Buffering messages are only sent for the active group (in case there
is more than one).

If the inactive group posts buffering messages we keep the last one
around and will post it once it becomes the playing one.

ec7d81f67c decodebin3: high cpu usage after eos
After eos, decodebin3 enters a loop sending eos events which causes high cpu usage.

1f792ab89d decodebin3: Handle dual-output of STREAM_START/EOS
In order to flush out multiqueue, we send again a STREAM_START and
then a EOS event.

The problem was that was that we might end up pushing out on the
output of multiqueue (and therefore decodebin3) a series of:
* EOS / STREAM_START / EOS

Apart from the uglyness of such output, If decodebin3 is used with
elements such as concat on their output, they might potentially
block on that second STREAM_START.

In order to make sure we don't end up in that situation we send
a custom STREAM_START event when refreshing multiqueue (which we
drop on the output) and we don't special case EOS events on streams
on which we already got EOS.

At worst we now end up sending at most two EOS on the output of
multiqueue (and decodebin3).

c1e902a084 playbin3: Implement gapless playback
Similar in vein to the playbin2 architecture except that uridecodebin3
are prerolled much earlier and all streams of the same type are
fed through a 'concat' element.

This keeps the philosphy of having all elements connected as soon
as possible.

The 'about-to-finish' signal is emitted whenever one of the uridecodebin
is about to finish, allowing the users to set the next uri/suburi.

The notion of a group being active has changed. It now means that the
uridecodebin3 has been activated, but doesn't mean it is the one
currently being outputted by the sinks (i.e. curr_group and next_group).
This is done via detecting GST_MESSAGE_STREAM_START emission by playsink
and figuring out which group is really playing.

When the current group changes, a new thread is started to deactivate
the previous one and optionnaly fire 'about-to-finish'.

b9e73d0575 playbin3: Use uridecodebin3 and link/reconfigure immediately
Apologies for the big commit, but it wasn't really possible to split it
in anything smaller.

* Switch to uridecodebin3 instead of managing urisourcebin and decodebin3
ourselves. No major architectural change with this.

* Reconfigure sinks/outputs when needed. This is possible thanks to the
various streams-related API. Instead of blocking new pads and waiting
for a (fake) no-more-pads to decide what to connect, we instead reconfigure
playsink and the combiners to whatever types are currently selected. All of
this is done in reconfigure_output().
  New pads are immediately connected to (combiners and) sinks, allowing
immediate negotiation and usage.

* Since elements are always connected, the "cached-duration" feature is gone
and queries can reach the target elements.

* The auto-plugging related code is currently disabled entirely until
we get the new proper API.

* Store collections at the GstSourceGroup level and not globally

* And more comments a bit everywhere

NOTE: gapless is still not functional, but this opens the way to be able
to handle it in a streams-aware fashion (where several uridecodebin3 can
be active at the same time).

ebf138e29e urisourcebin: Add 'about-to-finish' signal
With push-based sources, urisourcebin will emit this signal when
the stream has been fully consumed.

a8a5905ec6 playbin3: Fix accessing invalid index in GstStream when received select-stream event
If select-stream event was send to playbin3 as missing any GstStream of ES type
(V or A or TEX) of collection then, playbin will access to invalid address of
GstStream due to invalid index limit. This caused SIGSEGV.

38c835ec1e decodebin2: Don't spawn threads on shutdown
If we are shutting down, don't spawn a cleanup thread to cleanup old
groups and instead queue them to be cleaned up in the state change
thread.

This avoids (hopefully for good) having a race between the state change
thread and other threads trying to deactivate elements/pads.

e72aa501b0 decodebin2: Avoid deactivation races
Deactivating pads from two threads isn't 100% MT-safe. There is a
slim chance that the GstPadActivateFunc might be called twice with
the same values (in this case from the cleanup thread *and* from
the GstElement change_state function when going from PAUSED to READY).

In order to avoid that, call any existing cleanup function *before*
calling the parent change_state implementation on downwards state
changes.

77e5a71a15 decodebin2: Don't take locks when deactivating pads
When deactivating pads, we need to ensure that the streaming threads
going through the pads we wish to deactivate can cleanly return.
Failure to do that would result in the streaming locks of those
pads never being released. The end result would be a deadlock
when stopping decodebin2.

In order to avoid that situation, release the "dyn" lock around
the deactivation code. And refactor the code to cope with the
list of blocked pads having potentially changed when re-acquiring
the lock.

35a8d42724 parsebin: Don't let thread run after unref
We have a dedicated one-shot thread to handle cleanup of old groups.

While this is a good idea. It's an even better idea to make sure
that thread is *completed* before the parsebin element to which
it is related isn't freed/gone.

* There can only be one cleanup thread happening at any point in time.
  If there is already one, we wait for the previous one to finish.
* When shutting down (NULL=>READY) make sure the thread is finished

92e8876844 parsebin: Emit 'drained' only for the top-level chain
Instead of emitting 'drained' whenever every single chain is drained
(which would result in plenty of signal emission, and would also
occur when switching groups), only emit it when the top-level chain
is drained.

Furthermore, mark unknown (and therefore unexposed) pads as drained
since we'll never get EOS on them.

ce65017d03 decodebin3/urisourcebin: Switch to actual EOS events internally
Use the intended sequence for re-using elements:
* EOS
* STREAM_START if element is to be re-used

This avoids having elements (such as queue/multiqueue/queue2) not
properly resetting themselves.

When delaying EOS propagation (because we want to wait until all
streams of a group are done for example), we re-trigger them by
first sending the cached STREAM_START and then EOS (which will
cause elements to re-set themselves if needed and accept new
buffers/events).

b4899a5a65 playbin: Make sure to ref_sink() any sinks before calling activate_sink()
It is forwarding messages to the playbin bus, thus forwarding messages
that contain a floating reference to the application. This generally
makes bindings unhappy, we must not leak floating references to them.
