I don't believe anyone has yet implemented it.

The page in the wiki is the current draft spec.

The next step would be to implement it in your tool, offer feedback,
and then confirm against someone else's implementation.

Question About syncing
What exactly does it mean when, in the decoder_example.c file, you try to
extract the information from the comments and codebook headers and you loose
sync? What is actually being check to determine when sync is lost?. I known
one part of it is that there is a gaps in the stream. Is the CRC value the
determining factor? Please detail! I read a lot of the documents. I still am a
little fuzzy.

OggPCM family
Hi,
The Xiph Wiki contains the four pages:
OggPCM
OggPCM Draft1 (with Talk page)
OggPCM Draft2
OggPCM Draft3
Can I suggest that this be reduced to just one
(or maybe two) pages. I suggest this because
somebody has started making changes to
OggPCM Draft2. My guess is that this is not
desirable.
Regards,
Martin

status of oggpcm?
Hi All,
What is the status of the oggpcm project?
I'm investigation solutions to the following problem: losslessly encode
double-precision mutli-channel timeseries data in a format that is
compatible with free (libre) internet streaming technologies and that
permits diverse metadata to be encoded with the stream. flac isn't
suitable because it only supports integer data, lossy

Ambisonics und OggPCM
Hi,
this message is a cross-post to the Sursound and ogg-dev mailig list.
The developers on the ogg-dev list are defining the Ogg/PCM format and
on Sursound list there discussion about Amisonics file formats recently.
I have not been able to follow both disussion, just skimmed through. But
maybe you can work together to bring Ambisonics into Ogg/PCM? :)

clearification
Greetings,
How does the ogg_page_bos function work? I call this function directly
after calling ogg_sync_pageout. It works. Then I place a guard around it
until the start of a new stream (chain mode). If this is the start of a
new stream, should it return zero after the next call. I looked in
ogg_page structure to see if there is a member named b_o_s, but I did
not see anything. What is being

oggPCM for general data
Greetings,
I am building a data collection system that will ultimately have 28 channels
and multi-rates up to 2 M/sec. I need some sort of lossless format framing
and header system to transfer the data to a desktop PC over USB. Rather than
reinvent, I looked around to see what others are using and for existing
tools for testing. Surprisingly, I found few general purpose data formats
that can

frame length
?Greetings,
I am new to this forum and also to programming in general. I have desire
to try to use Ogg as my default streaming encoder. I have a quick
question. How does someone determine a frame length in ogg? For example
if I was to use an mp3 frame, I would try to do something like this:
frameSz = 144 * BitRate / (SampleRate + Padding). Also is there a
tutorial on how to correctly use the

Ambisonics und OggPCM
This is getting very dangerous. We cannot take our flamewar to outside mailing lists without making a complete fool of ourselves. Arc, would you please refrain from doing so in future and rather come to an internal agreement beforehand?
Arc, there are a few things you have missed:
The discussion on OggPCM2 was friendly and constructive and there were no flame wars and the spec got much further

The project has been forked, not superceded.
Work on OggPCM is continuing, the team working on OggPCM2 is free to submit
their own draft but some are not welcome to continue work on OggPCM due to
their recent social conduct.

In one of the last monthly meetings it was decided that OggPCM is
ready and all it needs is an implementation (for instance, in ogg123).
The problem is that nobody seems available to do it. If either
Martin or Sampo would like to work on it, I believe nobody will
oppose.
CMML and Skeleton implementations are far more urgent right now, though.
I have changed the main page in the XiphWiki to

OggPCM: support for little-endianness only?

Then recommend one single format. Nobody *has* to support all of the
features present, yet it makes sense to *allow* common variances. Most
of all, because:

No. I started OggPCM, since it was never proposed to Xiph.org it remains my
trademark until which time it is accepted by

OggPCM: support for little-endianness only?
List,
A recent discussion over on XiphWiki is trying to decide if OggPCM
should support only little-endianness or the usual combo of big and
little.
It started with the following statement by an user (Qqq):
"Portable players are usually ARM, which is usually little-endian. The
Macintosh is now little-endian. Obviously the PC is little-endian.
Clearly there is a winner. It's long past

OggPCM channel maps
I've tried to solicit discussion on this point in the past, but now I'd
like the press the issue for a bit. I'd like to remove the less well
developed mapping header (option 1) from the OggPCM draft, and make
my/our (with Martin Leese) suggestion (option 2) the definitive one.
If anybody objects, let's discuss it on-list. If not, I think it
wouldn't be too bad of an idea

My thoughts exactly.
