19b7b248cc uridecodebin3: Fixed defauts not being set on initialization 
The default values were not being set on element initialization. This
was a problem for buffer_duration and buffer_size since they would be
zero initialized, rather then being set to -1. This would cause the
underlaying queue2 element to have no limits and depending on the
streamed file, could cause queue2 to allocate massive amounts of memory.

f4bcf8290b playbin3: handle GST_PLAY_FLAG_FORCE_SW_DECODERS 
In decodebin3 and uridecodebin3 the `force-sw-decoders` boolean property is
added. In uridecodebin3 it is only a proxy property which will forward
the value to decodebin3.

When decodebin3 has `force-sw-decoders` disabled, it will filter out in its
decoder and decodable factories those elements within the 'Hardware'
class, at reconfiguring output stream.

playbin3 adds by default GST_PLAY_FLAG_FORCE_SW_DECODERS, and sets
`force-sw-decoders` property accordingly to its internal uridecodebin, also
filters out the 'Hardware' class decoder elements when caps
negotiation.

f3182a88b1 playbin2: handle GST_PLAY_FLAG_FORCE_SW_DECODERS 
Added `force-sw-decoders` boolean property in decodebin2 and
uridecodebin. By default the property is %FALSE and it bypass the new
code. Otherwise the factory list is filtered removing decoders
within 'Hardware' class.

uridecodebin sets the `force-sw-decoders` property in its internal
decodebin, and also filters out Hardware class in the
autoplug-factories default signal handler.

playbin2 adds by default GST_PLAY_FLAG_FORCE_SW_DECODERS it its flags
property, and depending on it playbin2 sets the `force-sw-decoders`
property on its internal uridecodebin, also filters out the Hardware
class decoding decoders at the autoplug-factories signal handler.

0a515acfa8 playbin3: Propagate sink context 
When the playsink's sink is activated its state is set to READY but it remains
unlinked. So, in order for decodebin3 to potentially reuse the context later on,
the whole playbin3 needs to have it internally stored.

fab2d6d60c audiorate: Update next_offset per rate change

494ee67446 playbin: Handle error message with redirection indication 
There are in the wild (mp4) streams that basically contain no tracks
but do have a redirect info[0], in which case, qtdemux won't be able
to expose any pad (there are no tracks) so can't post anything but
an error on the bus, as:
  - it can't send EOS downstream, it has no pad,
  - posting an EOS message will be useless as PAUSED state can't be
    reached and there is no sink in the pipeline meaning GstBin will
    simply ignore it

In that case, currently the application could try to handle that but it
is pretty complex as it will get the REDIRECT message on the bus at
which point it could set the URL but playbin will ignore it, as
it will only be for the next EOS, it thus need to set the pipeline to
NULL (READY won't do as it is already in READY at that point). And it
needs to figure out the following ERROR message on the bus needs to be
ignored, which is not really simple.

The approach here is to allow element to add details to the ERROR
message with a `redirect-location` field which elements like playbin handle
and use right away.

We could also use the element 'redirect' message in playbin, but the
issue with that approach is that the element will still emit the ERROR
message on the bus, leading to wrong behaviour. That can't be avoided
since in the case the app/parent pipeline is not handling the redirect
instruction, the ERROR message is necessary (and there is no way to
detect that the message has been "handled" from the element emitting the
redirect).

a724f9ddfb encodebin: Ensure that a single segment is pushed into encoders 
Following the [design document] encodebin needs to handle sources that
output multiple streams, for that purpose and to make it simpler,
we ensure that a single segment is outputted to the encoders by using
an `identity single-segment=true` at the beginning of streams chains.

Added API to enable or disable the use of that new feature.
Added support for the encoding profile parser for that new property,
keeping backward compatibility

33acf73334 audioconvert: Fixed changing mix-matrix at runtime 
Setting the property again after it had already been set ran
g_value_unset() but did not initialize it again to g_value_copy() failed
afterwards. Removed the unset as cleanup is done implicitely from
g_value_copy().

Changing the mix-matrix property did not trigger reconfiguration of the
caps, this has been added.

If the matrix is set to an empty matrix, instead of copying this the
matrix is simply disabled by setting mix_matrix_is_set (formerly
mix_matrix_was_set) to FALSE so the mix-matrix is ignored from now on.

c363747251 videorate: Fix max-duplication-time handling 
Previously this would've only set discont=TRUE and then for all future
buffers simply returned immediately.

Instead we also need to
  a) drain previous input until its buffer time
  b) update next_ts and base_ts accordingly for the gap
  c) actually store the new buffer after the gap so it can be used in
     the future and so the old buffer before the gap is gone

Also update the unit test accordingly so that it actually tests for this
behaviour. Previously it only tested that after the gap we got no output
at all.

96c6f581ae streamsynchronizer: avoid pad destruction races. 
Due to the use of {set/get}-element_private methods being used to store
the GstSyncStream in the src and sink pads, and the racey nature of pad
destruction, there are numerous ways we can be bitten by race conditions
in the stream synchronizer. Fix that by tying the pads toghether with
references.

9af8516873 streamcombiner: Forward upstream force-key-unit events to all sinkpads 
streamcombiner element forwards a upstream event only to one sinkpad.
When the streamcombiner is used with encodebin, the sinkpad
corresponding to pass-through path is configured before that of encoder,
and therefore streamcombiner forwards upstream events only to
the firstly configured one (i.e., pass-through path).

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.

abd80b6561 compositor: Copy frames as-is when possible 
The blend functions for alpha formats need to do more work than just
doing a memcpy, so we can do a memcpy when we know that a blend is not
actually needed.

1080p AYUV ! compositor background=transparent ! fakesink - 56% faster

Specifically, when we don't draw the background and the first pad we
draw completely covers the output frame, we can just copy it as-is.
The rest of the pads (if any) will get composited on top normally.

As expected by the property getter.

Basically there are cases where we can be getting the source from
any thread and in another thread bring back the element from PAUSED
to READY, which leads to a critical warning (or worse).

The only place where we use `->source` outside the property getter is
the change_state function so the current way of setting/reading it
should be safe.

4f73d3cf80 decodebin2: fix pad leak and problem with GWeakRef code 
Follow-up to !160 and commit 6a99ad2c.

Firstly, don't leak the sinkpad. g_weak_ref_get() returns
a strong reference (unless it returns NULL), so that must
be unrefed, as detected by the playbin-complex and
discoverer unit tests.

Next, if we do that we get invalid memory access when the
final pad ref is dropped a few lines below after the
request pad is released. The reason for this is that
GWeakRefs are not movable once they're in use, because
their address will be stored inside the object. In this
case the GWeakRef was embedded inside the GstDemuxerPad
struct which in turn was embedded inside the GArray data
section, and when the GArray gets resized, the structs
move. Just KISS and use a list with individual allocations
for each DemuxerPad instead.

6a99ad2c02 decodebin2: Make sure to remove probes when free GstDecodeGroup 
Nothing guarantees that when we free a DecodeGroup the demuxer pads
have already been freed and thus the probes have been removed meaning
that in some case it is possible that the pad probes still get called
*after* the GstDecodeGroup is freed, leading to segfaults (as we use
the freed group in that function).

c656cfb170 audiotestsrc: Improvements to the "ticks" wave 
(Initially discussed in
https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/issues/305)

The ticks waveform can be useful for audio synchronization diagnostics
and other cases where the time offset between waveforms is important.
However, in its current form, it is too limited, and has problems with
discontinuities, which result in severe artifacts when this waveform
is output by a DAC.

This patch fixes some discontinuities and considerably expand the ticks
waveform's flexibility. They also introduce the notion of a "marker tick";
every Nth tick can have a different amplitude (usually one that is larger
than the others). This is useful for combining frequent oscilloscope
triggering with large time offset detection. For example, without marker
ticks, the tick intervals must not be too small, otherwise the maximum time
offset that can be unambiguously detected is quite small (for example, if
the interval is 50ms, then no time offset larger than 25ms can be
unambiguously recognized). If the tick intervals are too far apart, then
no sudden changes can be clearly observed, since the oscilloscope is not
updated quickly enough. But with marker ticks, this is not an issue: If
there's for example a tick every 100 ms, then the oscilloscope can be
triggered every 100 ms. And, if every 20th tick is a marker tick, then
time offsets of up to 1 second can be discovered, even though the time
between ticks is 100 ms.

The patch also applies some minor cleanup to the audiotestsrc documentation.

audioconvert's passthrough status can no longer be determined
strictly from input / output caps equality, as a mix-matrix can

We now call gst_base_transform_set_passthrough dynamically, based
on the return from the new gst_audio_converter_is_passthrough()
API, which takes the mix matrix into account.

8b69b689c0 urisourcebin: limit the byte size of the queue based on the buffer-size 
Use the bitrate advertised by queue2 to determine the limits to
set across possibly multiple queue2/downloadbuffer elements.  e.g.
with two queue2's and a max-bytes based on the ratio of the
bitrate/cumulative_bitrate multiplied by the buffer_size set on urisourcebin.

This allows finer grained control over the buffer used by all the queue
elements inside urisourcebin.  Instead of a maximum of
n_streams*buffer_size being used, only buffer_size will be used however
we will fallback to n_streams*buffer_size if one of the queue2's does
not have bitrate information.

e87fa73e60 compositor: Implement different operators via per-pad property 
This removes the crossfade-ratio property and replaces it with an
operator property. Currently this implements the following operators:

- SOURCE: Copy over the source and don't look at the destination
- OVER: Default blending of the source over the destination
- ADD: Like OVER but simply adding the alpha instead

See the example for how to implement crossfading with this.

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.

62e4e15245 playsink: audio visualization support fixes 
The queue between the audiotee and the audio chain wasn't properly added to the
bin, leading to streamsynchronizer locks on EOS. Reconfiguration of the
visualization chain wasn't working as expected either. It is now possible to
dynamically enable/disable the audio visualization support.
