From a1b913f56dfd61dc51a49482277c50bbae67f2c1 Mon Sep 17 00:00:00 2001 From: Ralph Giles Date: Thu, 10 Jan 2013 17:00:18 -0800 Subject: [PATCH] Clarify how grouped streams are not "Ogg Opus files". We mean to make .opus only for degenerate--not concurrently multiplexed or grouped--but optionally sequentially multiplexed or chained physical Ogg streams. However, we don't mean to say you can't use this draft with such streams. Also, replace the reference to RFC3534 with RFC5334, which obsoletes the previous reference by defining video/ogg and audio/ogg. --- doc/draft-ietf-codec-oggopus.xml | 16 +++++++++++----- 1 file changed, 11 insertions(+), 5 deletions(-) diff --git a/doc/draft-ietf-codec-oggopus.xml b/doc/draft-ietf-codec-oggopus.xml index c6291d2e..aa036482 100644 --- a/doc/draft-ietf-codec-oggopus.xml +++ b/doc/draft-ietf-codec-oggopus.xml @@ -2,9 +2,9 @@ - + ]> @@ -1142,9 +1142,6 @@ Elements such as the Ogg page capture pattern and the magic signatures in the An "Ogg Opus file" consists of one or more sequentially multiplexed segments, each containing exactly one Ogg Opus stream.
