There seem to be a couple of inconcistanies in the Ogg spec as regards to
lacing values:

fractional segment of < 255 bytes." However, in the wild, I've

Lacing Values
I noticed that, when decoding an ogg vorbis file that was encoded with
the xiph library, that the comment header and setup header are encoded
on one page. Okay, the vorbis documentation says you can do this, no
problem. My question is, the lacing values seem to indicate where the
packet boundaries for the two of these are, is this required, or is this
just a hint?
Further, I'm seeing

Ogg Vorbis Framing
Hi all,
Here are some thoughts on Vorbis framing, which may make it easier to
stream Vorbis in real time. The suggested changes also move more audio data
closer to the beginning of each page. A note in the Vorbis framing spec suggests
a simple 'bandwidth limited' mode whereby important information is placed at the
front of each page and the end of each page is discarded. When operating

Ogg spec
Hi,
I'm currently trying to implement the Ogg specification in pure Java
from scratch. (I know, something like that does exist, but that's a rewrite
from C, at least that's my impression).
I'm a bit confused with the number of lacing values/segments in a page,
and the maximum length a page can have. The specification says, that
there can be 255 segments in a page, 255 bytes each

Someone could tell me the question about the question about lacing values

I mean i know what happens about segmentation but reading ogg specs
i didn't understand this lines:
"We simply add the lacing values for the total size; the last lacing value
for a packet is always the value that is less than 255. Note that this
encoding both avoids imposing a maximum packet

OK, so given the fact that a page can also contain multiple packets this
means that the lacing values of one page could be like the following example:

Am I missing something?
Hey all,
If my understanding is right, there's a serious big in vorbisfile.c, in
the routine _fetch_headers(), which will only show up when comment
packet spans multiple pages. The code to read the first 3 Vorbis
packets ogg_stream_pagein() once, then calls ogg_stream_packetout().
The problem is that ogg_stream_pagein() only adds a single page to the
ogg stream state, whereas

Does ogg segments include more than one Vorbis frame
Hi, Guys:
Does anybody know is it allowed for the OGG segment including more
than one Vorbis frame? Or should I consider about that?
I am working on OGG+Vorbis player now, but met some cases that OGG
segment includes some garbage bytes after one Vorbis frame, I want to know
whether it's safe if I just drop the left bytes after decoding one Vorbis
frame?
I read the page

Re: Ogg format and latency
Hi Aaron,
thanks for your thoughts on improving the Ogg encapsulation format. As
Monty was the person who developed the specification, I am forwarding
your suggestions to him. Maybe some of these changes can be adopted into
a future version of the Ogg encapsulation format.
Best Regards,
Silvia.

New Ogg Dirac mapping draft
David Flynn has proposed a new Ogg Dirac mapping. The draft is here:
http://davidf.woaf.net/dirac-mapping-ogg.pdf
This is a much bigger break from other codecs than my draft (at
http://wiki.xiph.org/index.php/OggDirac). We talked a bit about it on
IRC today. Below is my summary; hopefully David can correct anything
I got wrong or misleading. Comments?

Has anyone been able to get the Lace (ajax chatroom) ported over to Ruby
for a Ruby on Rails implemention? (The current version is PHP-based) ...
or is there a ROR-chatroom distribution that exists?
Thanks!

samba-tool domain classicupgrade fails to import users or groups from NT domain
I am attempting to migrate a Slackware server with Samba 4.12.3 from an
NT style domain to AD. I have done this about 7-8 times on other servers
in the past following the instructions on Samba's wiki. This time
however, the upgrade process is failing completely to import any users
or groups from the NT domain.
I have enclosed below the output of the classicupgrade command - I can't
