In line as well :
The first stage of the work has not been done yet : the detailed technical
requirements have not been defined and agreed yet,
the second stage of the work with other SDOs to analyse if already exiting
codecs meet these requirements is not done
and yet the Charter on the basis of which this WG could be launched is
formulated as if the conclusion resulting from this 2 stages was known and
obvious : no existing codec is suitable and so a new codec is needed
so, again : only these first 2 steps (requirement definition and standard
analysis) are, at this stage, relevant to start a WG since the next steps
depend on the conclusion of this work.
for instance , there could be some middle way between developping a new codec
and reusing an existing standard : it could be much more efficient to simply
extend/adapt an existing standard and, to achieve this, it would be better to
rely on the SDO that have standardized this codec.

What I try to say is that first the requirements must be set, only then
will it be possible for representatives of other SDOs to determine if already
standarddized codecs (or codecs under standardization) meet them.
I agree. Obviously no one (inside or outside the IETF) can tell exactly how
existing codecs in other SDOs relate to this work until the detailed
requirements are locked down.
Also, I think the burden is mostly on CODEC to make this assessment. Other
SDOs may offer their views in liason statements, and can respond with their own
work programs. But in the end it would be up the IETF to decide if there is
too much overlap.
