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 -- Martin J Leese E-m...

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 than OggPCM. There were many more people involved in the discussion on OggPCM2 than on OggPCM and thus Erik jumped to the conclusion that it has superceded OggPCM. OggPCM2 is covering a broader field of appl...

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...

...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? :) http://wiki.xiph.org/index.php/OggPCM

...ing 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 handle many channels and high multi-rate data. However, ogg and oggPCM looks like a good fit. I have some questions getting started. Is the oggPCM codec just header definition on a web page? Is anyone using it? I have not found the header file yet, does it exist? Has anyone built libogg and/or liboggz using a cross compiler such as the arm-elf GNU port? I am...

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. I'm requesting that the team working on OggPCM2 rename their pro...

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 change...

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 if I made the proper adjustment to the OggPCM spec in, say, 30 days time. -- Sampo Syreeni, aka decoy - d...

Just a quick note, realizing that many interested parties on vorbis-dev may not be subscribed to ogg-dev.. We're working out the details for an OggPCM codec, an uncompressed audio interchange format which will be used by the next generation Ogg framework. You can read what's taken place on this so far on the wiki and list: http://wiki.xiph.org/RawCodecs http://wiki.xiph.org/OggPCM http://wiki.xiph.org/Talk:OggPCM http://lists.xiph.o...

...clear whether with PCM sampling of devices this is actually a common (or even used) case. Do you know how multi-channel sound is sampled? Is it created with different widths/rates on different channels? If it is not a common case, we can leave the solution to different streams and keep it outside OggPCM. If it's common and the data comes interleaved in one stream, we should discuss including it into OggPCM.

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.

No. I started OggPCM, since it was never proposed to Xiph.org it remains my trademark until which time it is accepted by Xiph and by myself for release. It would be similar to me releasing Speex v2.0 - it is not my right, because you used and promoted the name first, and that makes it yours. If I were to fork Spe...

Arc, I always thought of you as a harmless idiot, but I no longer think you are harmless. You are now alone working on the OggPCM because everyone got tired of your power trip (I always thought some power was required to do that). Funnily enough, from the moment people gave up on you, it took only 24 hours to write a much better OggPCM definition than what you had (even though we don't consider it complete yet). How is th...

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 w...
