| I am not sure but are you suggesting that the IETF will define the
| requirements, metric and quality assessment requirements and all
proposed

best codec
| bases without discussing the codec itself. This is what I would
call a
| selection process (at least in ITU terms).
The WG can decide how it wants to go about the process, I'd just prefer
that
the charter not (effectively) rule out selection of something that
already
exists with an assumption that something entirely new will be created.
| The problem is that the IETF process allows anyone to contribute to
existing
| work hopefully leading to a better the end result.
Of course, but also be aware that there's no one definition of
"better".
Something that can be defined quickly and used immediately might be
much
better than something it takes 5 years to create and more to implement,
even if the invented one saves a little bandwidth or has better loss
recovery characteristics.
This is the IETF process for better or worse, I asked similar questions and
the response is that the IETF decide what is better is based on rough
consensus.
BTW: my personal view is that your suggestion is in line with the process at
the ITU when doing codec selection, but there are people who prefer doing it
at the IETF using the IETF procedures for other reasons.
| What about the change control, does it stay with the original
contributor or
| can the IETF modify the codec based on input from other parties,
which means
| that the codec may change by the IETF anyhow.
The IETF will have change control over its protocol, of course, which
may
cause it to diverge from that upon which it was originally based. And
yes,
everything changes with time.
