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

Since the ogg pages (which I beleive are 4k) need to be unpacked anyway, there is little harm in having to (possibly) do endswapping as well.

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-mail: martin.leese@stanfordalumni.org Web:

I made a few updates to OggPCM2 http://wiki.xiph.org/index.php/OggPCM2 reflecting the latest discussions. Could everyone have a look at it and see if they agree. Otherwise, what do you feel should be changed? Anyone wants to speak in support of chunked PCM? For all those that are just tired of this mess like me, please express yourself in the new spec I created: OggPCM3
