I am the assigned Gen-ART reviewer for this draft. The General Area
Review Team (Gen-ART) reviews all IETF documents being processed
by the IESG for the IETF Chair.  Please treat these comments just

Document: draft-ietf-codec-oggopus-10
    Ogg Encapsulation for the Opus Audio Codec
Reviewer: Joel M. Halpern
Review Date:
IETF LC End Date: 27-January-2016
IESG Telechat date: N/A

Summary:
    This document is nearly ready for publication as a Proposed Standard.
    The reviewer believes the status issues needs to be addressed, and
would like the minor issue identified below discussed.

Major issues:
    I do not see how we can have a standards track document for using an
Informational format.  RFC 3533 is Informational.  At the very least,
the last call needed to identify the downref to RFC 3533.  (It is not
clear whether the reference to RFC 4732 needs to be normative or could
be informative.)

I agree with the need to have the downref be explicit, but this has been
the norm since the IETF first decreed that RTP encapsulations should be
standards track.

I believe you were on the IESG at the time, too... it was that long ago.


Minor issues:
    While I do not completely understand ogg lacing values, there
appears to be an internal inconsistency in the text in section 3:
1) "if the previous page with packet data does not end in a continued
packet (i.e., did not end with a lacing value of 255)"
2) "a packet that continues onto a subsequent page (i.e., when the page
ends with a lacing value of 255)"
    The first quote says that continued packets end with a lacing value
of 255, and the second quote says that continued packets end with a
lacing value of less than 255.  At the very least, these need to be
clarified.

Nits/editorial comments:
    is there some way to indicate that the ogg encoding constraints
(e.g. 48kHz granule and 2.5 ms timing) are sufficiently broad to cover
all needed cases?

Yours,
Joel Halpern
