[AVT] Question from IANA abut registry for WAV and AVI codecs




I have tried to reach the authors of these registrations but failed to resolve the issue. Does anyone know if we have the wrong values in the registry and is so can you please suggest what values should be in the registry.


Thanks, Cullen <with my AD hat on>

Can you provide the URL for which registry you are referring to?

Sure thing:

http://www.iana.org/assignments/wave-avi-codec-registry

It seems that AC3 and DVM are mixed up. Or at least, I know a Format
Tag of 0x2000 means AC3 for sure.


I found this because of an AVI that wouldn't play sound. It's tag was
0x2000 and I looked it up in the registry (which identifies it as
DVM). I searched for the namespace type (audio/
vnd.wave;codec=2000)
and found this:

For instance, Tag2000 is AC3, yet in the RFC, AC3 is listed as Tag92.
It is the only listing for AC3 in the RFC :

Furthermore, tag2000 is in the list, but is listed as DVM. What in
the
world is DVM?

I'd like to provide an automatic codec download service, and I
planned
on using RFC 2361 as a reference. I can easily swap these two, but
I'm wondering if there are other entries that need fixing.
