5256f1e00c cea608tocea708: Fix SMPTE 334-1a field flag usage 
If the flag is set then this is field 0, otherwise it is field 1. The
code had this inverted. See also cece286fe8.

cece286fe8 ceax08overlay: fix field lookup for s334-1a 
As stated in the spec:

> Bit b7 of the LINE value is the field number (0 for field 2;
> 1 for field 1). Bits b6 and b5 are 0. Bits b4-b0 form a 5-bit unsigned
> integer which represents the offset [..]

Here, b7 is the most significant bit, this is what both cccombiner
and ccconverter agree on.

The overlay elements previously looked at the least significant bit,
which led to garbled text when both fields were actually present
in the CC meta.

71121a2380 aws: reimplement two separate wrappers for translate and transcribe 
The original awstranscribe element has grown too complex when
integrating translations for reasons that in retrospect were wrong:

As awstranscribe outputs words one by one, I decided we wanted to
perform translations there with larger sentences if available, but an
alternative design where a separate translation element is composed
downstream is also possible, as long as that element accumulates words
and enough latency is set on the transcriber.

An important difference is that the new elements do not expose unsynced
pads, this use case is instead now served by simple messages on the bus.

The elements should otherwise be at feature parity with the original
element.

A higher-level bin is also provided for convenience (and usage within
transcriberbin): translationbin.

A transcriber element can be provided to this bin, which exposes an
always audio sink pad, and an always text sink pad (for the
transcripts).

Additional source pads can be requested for translations, for now the
bin always uses `awstranslate` as the translator, but this can be made
configurable.

This element is usable as a transcriber in `transcriberbin`.

e3e7f55a8d transcriberbin: expose mix-matrix property on audio sink pads 
As the application expects to have the bin buffer the audio stream
internally and output it again unchanged, and transcribers might
expect a set number of channels, we need to expose a property to
let the user control how to downmix the audio stream teed through
the transcriber.

4406851ae7 transcriberbin: add support for speech synthesis 
This commit adds a new "synthesis-languages" property. Users can set it
to define a map of languages (typically translations) that should then
be routed through a "synthesis" bin, with its description specifiable
as the value of the map.

The output of this bin is then exposed as a new pad on the top-level
bin.
