This allows sharing it with other parts of the pipeline and avoids

bd14e476f1 Fix direct access to the inner specific formatted values 
This is no longer available as this could lead to building a defined
value in Rust which could be interpreted as undefined in C due to
the sentinel `u64::MAX` for `None`.

Use the constants (e.g. `ONE`, `K`, `M`, ...) and operations to build
a value and deref (`*`) to get the quantity as an integer.

05ece5560e tttocea608: expose roll-up timeout property 
In roll-up mode, when no more timed text comes in, the closed
captions may remain displayed on screen indefinitely (unless the
decoder implements a timeout, but that is not mandatory).

Expose a property to erase the display memory after a configurable
amount of time has elapsed instead.

b423febfbe videofx: Add colordetect video filter 
This new video filter is able to detect the dominant color in a video frame.
When the color has changed from the previous frame the filter posts an Element
message on the bus, the associated structure is named `colordetect` and has two
fields:

* a string field named `dominant-color`
* a list field containing the whole color palette, stored as uint values, sorted
  by dominance, with more dominant colors first

dd028ce97e [transcriberbin] - make audioqueue leaky 
If transcription runs slow or has issues the queue can fill up and block
all audio processing. This gives the queue a sufficent buffer and allows
it to drop audio if it eventually fills up. This was most noticable with
bad internet connections using the `awstrnascriber` where it would take
quite a while for the websocket to eventually timeout and the bin to
enter `passthrough=true`.

- Both: Inband and transcription captions are combined if exist.
  This is default behavior.
- Inband: Transcription buffers will be dropped
- Transcription: Caption meta of each video buffer will be dropped

In this version, transcriberbin doesn't provide any hint
for application to help caption source decision. That can be done
by application's strategy, passthrough status or probing inband
caption meta for example.

Not all ways of specifying border-radius as in CSS are implemented at

gets applied uniformly to all corners.

78d7cbd7dd cea608overlay: expose timeout property 
C.9 Automatic Caption Erasure (Preferred)

[...]

Some manufacturers have suggested building automatic timeout into their
decoders. They propose that if no data are received for the selected caption
channel within a given time, the decoder should automatically erase the
caption. Such erasure may supersede the intentions of the caption service
providers and institute one maximum display time for all captioning services.

If such a timeout is deemed necessary, however, the time limit should be no less
than 16 seconds, an amount of time said by caption service providers to be longer
than their most enduring caption. It is preferred, when automatic caption erasure
is used in a decoder, that only displayed memory be erased, since some caption
service providers may, contrary to recommended practice (see Section B.8.3), send
pop-on style caption data to non-displayed memory more than 16 seconds before
sending the EOC command which causes the caption to display.

The consequence of this is that the current roll-up window will

3cdc5870a1 transcriberbin: new high-level bin for speech to Closed Caption 
This new element puts together some of the elements we've written
in recent times (awstranscriber, tttocea608, textwrap, cccombiner)
into a convenience high-level element.

The design of the element is AV in -> AV (+ CC metas) out.

The element exposes property to set and unset a "passthrough" mode,
during which the transcriber element's state is set to NULL but kept
in the bin, in order for the user to be able to set properties on
sub elements no matter what the current mode is, using the
GstChildProxy interface.

In addition, the element ensures that the latency it reports stays
fixed so that playback continues uninterrupted.

0335893559 closedcaption: implement cea608tojson element 
This element outputs the same format expected by tttocea608 in
json mode.

It notably differs from cea608tott in that it only uses libcaption's
low-level API, as it needs to maintain its own view of the current
state of the screen, and make fine-grained decisions as to when
to output data and how to timestamp it.

It covers a large portion of the 608 spec, with the exception of
a few features that probably haven't ever seen widespread usage,
those are listed in a TODO list at the top.

It has been tested with a reference file produced by CEA and covers
all the features it demonstrates.

42b4defb5c tttocea608: in-depth refactoring, support for new input format 
Up to now, tttocea608 supported text/utf8, and no interface to
control the positioning of closed captions apart from new lines
in the input text.

CEA 608 supports a larger set of features than that, such as
positioning CC precisely in its 32 x 15 grid, styling text,
switching from one mode to another, resetting the base row
in roll-up mode etc ..

A custom, JSON-based format is now supported by the element
(caps application/x-json, format=cea608), allowing users to
control those features in a pretty advanced manner.

A side effect of this is that the approach previously used
by the element to ensure frame-accurate CC display is now
untenable: where we knew before that an input buffer would
at most span 74 buffers and calculate a somewhat reasonable
latency based on that, this is no longer possible. Instead
we pick the approach most CC encoders seem to pick, and
accept a certain latency at display time: for example the
flipping of the back buffer to the display buffer for a
10-character text buffer will occur 7 frames after its
PTS. This has obvious benefits in terms of code complexity
and should generally be acceptable.

+ Removes a now irrelevant test, updates other tests

+ Extracts the Mode enum to the root of the crate, it will
  be used by another element in a follow-up commit

a7180e3995 libcaption: fix bit set on indent preambles 
style preambles look like:

|P|0|0|1|C|0|ROW| |P|1|N|0|STYLE|U|

and column preambles look like:

|P|0|0|1|C|0|ROW| |P|1|N|1|CURSR|U|

Both preambles go through eia608_row_pramble(), the value they
pass as the x parameter is supposed to hold 4 bits, either
0|STYLE

or 1|CURSR

This value then gets bit-shifted by 1 and or'd in the second byte.

The value is also and' with 0x1E to ensure it can't leak into
the upper bits.

The previous code resulted in x being a 5-bit value, 0x10 (0b10000).
This resulted in outputting a style preamble, as 0x10 << 1 & 0x1E
is 0b00000. When the indent was 0 (the usual case), this went
undetected, but with any other value it resulted in no indent being
applied, but the text getting colored or italicized.

This patch fixes x to have the correct value of 0x8 | indent.
