Ogg metadata stream embedding
I suggest using the solution that CMML has come to use.
The XML file is essentially the same as an unencapsulated physical bitstream.
Then there is a mapping into a logical bitstream, where some of the
default information - in particular the XML header - are split off and
put into the bos packet - nothing really needs to go into the eos
packet. There's also a magic number and a version

metadata on the wiki
So wiki discussion on the new metadata format
is ongoing. I'd like to move some things about
a bit. MDMF is a discussion of the metadata
XML format itself, Metadata gives some
background an overview and a few old sample
cases. I'm not sure how many people read the
wiki talk page so I thought I'd ask here if there
were any objections before doing it. What would
most likely happen

Re: metadata
Hi Ian,
CMML is still a draft, so we can change the addressing if required. You're correct, currently something like
blah.cmml#fragment
points to a clip (or temporal section) of the stream, but
blah.cmml#t=12
points to a 12 seconds offset.
(same for annodex, i.e. ogg files with skeleton track).
For pointing to logical streams inside ogg, I'd really suggest you have a look at

If muxed with a video, it's insignificant (well, for my test cases).

Re: Embedding int32's within threora & vorbis files
What do you want to use OggPCM for? Why not use AU or WAV?
I can only see an advantage in using OggPCM if you want it annotated
using CMML or want to mix it with another codec, such as Theora.
Cheers,
Silvia.

The use for an XML based metadata format
What I've gotten out of this discussion so far:
1) we need to introduce a means in which to do captions; this could be
done through adding a "caption" element to CMML, or in another
time-continuous annotation format; so far I am not sure which would be
the better way
2) we need a XML annotation format for audio - in particular for music
- that is more structured than vorbiscomment

new server: NT_STATUS_LOGON_FAILURE
I've googled, RTFMed, and I still can't fix this. Hoping someone here
can offer a suggestion. I'm learning, so please explain a little if you can.
I installed samba on a Ubuntu 5.10 machine (named mog). My XP machine
"sees" it, but the username/password dialog fails.
I've traced it down to what I think is an authentication problem:

How Ogg mappings translate into the codecs parameter in Ogg media types
Hi all,
I am trying to set up the codecs table in the wiki and we have played
a bit with Dirac to find out what existing tools write into the
header.
The Schroedinger implementation by Fluendo uses (or used to use)
"KW-DIRAC" as the identifier in the Ogg header.
"BBCD" is the identifier of each of the Dirac data packages.
More recently, I read that the Dirac Sequence header

metadata on the wiki
The biggest problem with Vorbis comments are too loose specifications and
too little standardisation.
Another problem is attribution of involved parties. Currently only the
ARTIST field name is supported in software. More standardised field names
need to be worked out for organisations and persons involved in the
production of the recording. See:

ok i admit this statement came as a surprise for me.
cmml is about metadate/annotations, how can it be replaced
by KATE ( which is mainly about subtitles as far as i can see?

The use for an XML based metadata format
Daniel,
these are all good ideas and worth progressing. However, it may be
better not to merge too many goals in one format (MPEG-7 did that and
ended up as a big mess). So, I suggest to start by structuring the
types of things you want - then finding out which parts belong where
into existing formats such as vorbis comment, Skeleton and CMML, and
only then start to develop a new format.

Chained Vorbis Stream Distorting
Hi All,
I'm relatively new to Ogg and Vorbis and I've hit a pretty puzzling issue,
and I'm wondering if a veteran could help me out.
I'm attempting to decode a chained live Ogg Vorbis stream. The primary
issue is that the source does not exactly follow validation (I have no
control of this). The stream switches from a prerecorded segment, to a live
segment, back to a prerecorded

liboggz oggz_get_bos, oggz_get_eos
Hi,
I was wondering what oggz_get_bos and oggz_get_eos are supposed to do,
specifically are they meant to be used in oggz_read mode? The
documentation says "Determine if a given logical bitstream is at
[bos/eos]". However if get_bos is given a specific serialno it
returns that stream's b_o_s flag which, in read mode, is set on
initialisation. The serialno=-1 (for all streams)

This is roughly what was suggested the last time around.
A possible refinement is to provide a mapping from identifiers
to IDs so you could say "?oggid=myvideo".

Partial Function Application
Hi. I would like to partially apply a function to a list of arguments,
and I don't know how to do this in R, without perhaps writing default
values to the formals() of my function, or writing to the environment
object of a function. For context, my definition of partially apply
is: "fix some of the arguments, leaving the others as variables,
return a new function that takes the un-fixed
