fddd7df2d3 Don't call gst_ghost_pad_construct() anymore
It's deprecated, unneeded and doesn't do anything anymore.

0314b482f3 Don't pass default GLib marshallers for signals
By passing NULL to `g_signal_new` instead of a marshaller, GLib will
actually internally optimize the signal (if the marshaller is available
in GLib itself) by also setting the valist marshaller. This makes the
signal emission a bit more performant than the regular marshalling,
which still needs to box into `GValue` and call libffi in case of a
generic marshaller.

Note that for custom marshallers, one would use
`g_signal_set_va_marshaller()` with the valist marshaller instead.

596a4ee12f parsebin: Add missing locks/unlocks of the chain mutex
Before freeing pending pads it is required to hold the mutex, that's
what is protecting the list of pending pads in other places.

268c5e7e17 parsebin: Don't try to continue autoplugging a parser if we got raw caps
Otherwise we'll fail with an unhelpful message that no decoder for the
raw caps was found if a container contains raw media.

89d0e9cc92 parsebin: Post STREAM_COLLECTION on EVENT_STREAM_COLLECTION
Otherwise decodebin won't get notified about STREAM_COLLECTION comming
from the sources and thus will never get informored about it. Without
being informed about the stream collection decodebin won't be able to
select any streams. It ends up not creating any output for the streams
defined from outside parserbin.

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

d53ccfd8e5 parsebin: Check for shutdown before exposing pads

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.

c2a91d2cfd playback: Fix a small race on decodebin/parsebin shutdown.
When shutting down decodebin2 and parsebin, they set their
output pads to flushing, and there is a very small window
where elements might send a sticky event such as a tag event
(which silently fails due to flushing) and then sends a buffer,
and the buffer will return GST_FLOW_ERROR because it can't
forward sticky events. The element will then send an error
message on the bus. This can also happen when elements send EOS
just as shutdown is happening. Since we're about to destroy all
the elements inside parsebin and decodebin anyway, just discard
error messages from them.

A nicer but more difficult fix for GStreamer 2.0 is to make
all event pushing / handling in core return a GstFlowReturn
like buffers do, so we can report a FLUSHING state cleanly.

9517bd9b34 parsebin: Ignore failure to send sticky events
When plugging and then exposing a parser, don't fail
if it fails to send sticky events. The most likely
reason is that things were flushed due to the app
immediately doing a seek, but we can't detect flushing
separately to other error conditions without a
gst_pad_send_event_full() core function that returns
a GstFlowReturn.

83f30627cd decodebin3: fix collection leak
The collection owned by GstDecodebin3 has to be unreffed when disposing.

gst_event_new_stream_collection() doesn't consume the collection passed
to it so no need to give it an extra ref.

51055f1924 decodebin3: fix caps leaks
gst_stream_get_caps() returns a reffed caps.

The caps passed to gst_query_set_caps_result() are not transfered.

The caps in gst_parse_pad_stream_start_event() was either acquired
using gst_pad_get_current_caps() which returns a new ref or
explicitly reffed.

d514e79bee playback: New elements
With contributions from Jan Schmidt <jan@centricular.com>

* decodebin3 and playbin3 have the same purpose as the decodebin and
playbin elements, except make usage of more 1.x features and the new
GstStream API. This allows them to be more memory/cpu efficient.

* parsebin is a new element that demuxers/depayloads/parses an incoming
stream and exposes elementary streams. It is used by decodebin3.
It also automatically creates GstStream and GstStreamCollection for
elements that don't natively create them and sends the corresponding
events and messages

* Any application using playbin can use playbin3 by setting the env
variable USE_PLAYBIN3=1 without reconfiguration/recompilation.
