264d91a502 baseaudiosink: fix latency calculation for live elements
Max_latency was computed on already adjusted min_latency. Introduce a new
variable for clarity. Spotted by Blaise Gassend.

5d0f279fea baseaudiosink: drop samples that are too late
... rather than having all of them rendered at 0 or subsequently aligned,
likely inevitably leading to repeated resyncing.

dad50ad1fe baseaudiosink: recalibrate clock on setcaps
Because the spec for the ringbuffer can change when changing
the caps, we must recalibrate the clock.

8ff93a6a3d audio: Add an IEC 61937 payloading library
This can be used by sinks to take compressed formats, correctly payload
these in IEC 61937 frames and feed these to sinks that support
passthrough output over IEC 60958 (S/PDIF) or, in the case of MP3, over
Bluetooth.

Initial implementation includes AC3, E-AC3, MPEG-1, MPEG-2 (non-AAC),
and DTS (type-I/II/II) payloading. More formats can be added as needed.

643e5f586c baseaudiosink: Allow subclasses to provide payloaders
This allows subclasses to provide a "payload" function to prepare
buffers for consumption. The immediate use for this is for sinks that
can handle compressed formats - parsers are directly connected to the
sink, and for formats such as AC3, DTS, and MPEG, IEC 61937 patyloading
might be used.

9615081f9c ringbuffer: Add support for E-AC3
Adds support for pushing E-AC3 buffers and doing bytes-to-ms conversion
correctly. The assumption (as with other formats) is that something like
IEC 61937 payloading will be used. Correspondingly the ringbuffer spec
is populated so that the data rate is 4x normal AC3.

0f8edca902 baseaudiosrc: Add src object lock around call to ringbuffer parse caps.
A race was observed between query() and setcaps() where the latter would
change the ringbuffer spec while the former was performing operations

63cfa2a50d baseaudiosrc: protect against ringbuffer disappearing while in a query

hence the spec pointer was no longer valid, and
gst_util_unit64_scale_int crashed (assertion `denom > 0´failed)

Add locking to make sure the ringbuffer can't disappear.

588ac0ae6f baseaudiosink: don't allow aligning behind the read-segment
Given a large enough drift-tolerance, one could end up in a situation
where one would keep aligning the written buffers behind the current
read-segment position. The result for the reader would be complete
silence, possible preceded by very choppy audio.

By checking the available headroom, one can determine if there is
room to do alignment, or if one should resort to a resync instead to get
the pointers back on track.

Also refactor the alignment-logic out of the render function for cleaner
code.

e73f293ee5 baseaudiosink: arrange for running clock when rendering eos
Commit ba2e500bd9 ensured to provide
a running clock when EOS had finished rendering.  However,
other measures are needed (and were in place before) to ensure a
running clock when EOS still needs rendering (i.e. waiting).

So, specifically, re-introduce eos_rendering removed in aforementioned commit,
this time as a public variable so subclasses can be aware of the situation.

Fixes (part of) #645961.

0ed757db33 gobject-introspection: use same PKG_CONFIG_PATH for g-ir-compiler as for g-ir-scanner

just relying on an env-var set one. This makes sure both g-ir-compiler
and g-ir-scanner use the same PKG_CONFIG_PATH for determining include
paths etc.

60ff7c0eb4 baseaudiosink: protect against ringbuffer disappearing while in a query
Observed a case where the sink went to null-state during the query,
hence the ringbuffer-pointer was NULL, causing a crash.

Moving the ringbuffer-check code until after the query, and hold the
lock during the check and while using the spec-values. It should not matter
to the query wether the ringbuffer is present or not, and it actually
gets a time bit more time to get the ringbuffer set up in this case!

24226284b8 baseaudio: avoid taking extra ref on sink/src
Don't take an extra ref on the sink and source because that creates a reference
cycle. Instead, use the invalidate method of the clock when the sink and source
are freed. This way, we don't call into the time function anymore after the
objects are disposed.

When calling gobject-introspection scanner, make sure our own

first in the PKG_CONFIG_PATH. May or may not help to make sure
that it doesn't pick up older external plugins-base libs (or
.gir files) from outside the source tree / build directory as
dependencies of the introspected lib instead of using the
stuff we just built in a sibling directory.
