8d645e1a69 encodebin: Be less restrictive on muxer caps when preset name is specified
This way the user can simply define its caps by only providing the
structure name which is what we do in the encoding profile
deserialization function for example.

1cead20777 encodebin: Fix and refactor smart encoding
It was not working properly and the implementation of the smartencoder
element was weird. This introduce a number of changes (which are all
in one single commit because they basically all work together and lead
to basically reimplementing the element):

* Make smartencoder a bin so that the reencoding chain of elements are
  inside of it instead of not having any parent. Those elements were not
  be visible when dumping the pipeline which was very confusing.
* Make encodebin create the right encoder with a capsfilter (and parser)
  to properly enforce the format specified by the user, and so that the
  encoder properties specified in the encoding profile are respected.
* Use `decodebin` to do the decoding instead of selecting a decoder
  ourself and not plug any parser etc...
* Ensure that negotiated format in the sinkpad of smart encoder is fixed
  through time when the user requested a non dynamic output
* Add a parser at the beginning of the smart encoder
* Handle errors when reencoding

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

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.

9ce8cf89ba encodebin: Also lock input caps when dynamic output is disabled
With the way caps negotiation work in encoders, the only way to ensure
that no downstream renegotiation is done in the encoder is to also lock
upstream caps. Anyway with the current behavior upstream of encoders
*require* to handle any file format so locking upstream format should
be safe.

25e0b77bbe encodebin: Don't try rate adjustment before the first buffer
With both audiorate and videorate, it seems more sensible to apply rate
adjustments after the first buffer appears. For example, with v4l2src,
there is often a small delay before the first video buffer turns up, and
this can cause a stuttery start because of videorate trying to ensure a
perfect stream.

c8ea302e57 encodebin: Fallback to other profile if we fail with one
In some case we might have EncodingProfile that will be defined

profile for that stream should be used.

A test is added showing the feature.

0c0f803488 encodebin: Fix special case
Allows to run such a command line :

gst-launch-1.0 uridecodebin uri=file:///home/meh/Music/sthg.mp4 ! \
encodebin profile-string="audio/x-wav|1" ! filesink location=sthg.wav

Previously the code failed because wavenc is considered as a muxer.
We still want encodebin to audio/x-wav as an AudioEncodingProfile,
so this simple fix allows that.

Ability to mux raw streams in containers such as matroskamux
is a different issue.

72c05d1cbb encodebin: Add a way to disable caps renegotiation for output stream format
In some cases, the user might want the stream outputted by encodebin to
be in the exact same format during all the stream. We should let the
user specify when this is the case. This commit add some API in the
GstEncodingProfile to determine whether the format can be renegotiated
after the encoding started or not.

API:
    gst_encoding_profile_set_allow_dynamic_output
    gst_encoding_profile_get_allow_dynamic_output

c9904fb639 encodebin: delay missing encoder error as passthrough is still possible
Set up a fakesink with a pad probe to replace the missing encoder to detect
if encoding was really required and only error out in this case. Otherwise
just let passthrough branch work.

This delays the error posting from the set_state function to when buffers
are really flowing. Unit test updated accordingly

bccfc679b5 encodebin: activate ghost pad after creating it
This ensures the ghost pad will not stay in flushing mode
when it receives a flush stop event, and generally behave
badly.

This fixes at least one case of a dynamic decodebin2 + encodebin
pipeline finding a source that has not prerolled when it should
have been (due to the ghostpad staying in flushing mode).

7358cba017 encodebin: Make use of the new preset_name when setting a preset
The behaviour is sensibly changed here. Instead of purely falling when a
preset is set on the #GstEncodingProfile, we now make sure that the
element that is plugged corresponds to the one specified as preset. Then,
if we have a preset_name, we use it, if it fails, we fail (we might rather
just keep working even without setting the element properties?)

 + Add tests that it behave correctly
