Hi Bernard,

The agreement to specify a mandatory-to-implement video codec to avoid
negotiation failure is a very long standing one.  If you believe the MTI
should be VP9 or H.265, you are welcome to propose either; please do so,
however, in the form of a draft by October 6th so we can move forward
knowing that it is your proposal.

regards,

Ted Hardie
