Hello list, We have recently introduced the codecs (optional) parameter on the Ogg media types for easier identification of encapsulated codecs in conditions were it's not feasable to examine the streams directly. I received a comment from the IESG that we should have some sort of list to describe how Ogg mapping strings translate to codec parameter strings, so I went ahead and compiled a

The spec seems to be unclear on this: should two comment haeders who only differ in the order of comments be considered equevalent? VCE shows comments in the order read and allows to store them in any order (it has move up/down buttons). Comment editors with a fixed layout (like the commmon TITLE/ARTIST/etc. fields in PP's winamp plugin) don't show the order and give no control of it.

I've tried to understand the codebook matter (but haven't yet had time to read the source). I want to understand how ibg is the flexibility resulting from packing the codebook in the header of every bitstream. Can we, for example, change the volume of the whole sound by scaling the vectors in the codebook? (My guess is that this wouldn't be enough, as we have to scale the floor of

I happily downloaded the official beta4 winamp plugin as well as Mattew's versions with VCE interated and with/without the dialog. When I installed it winamp (v2.72) didn't recognize it (no vorbis plugin listed in the config, doesn't play ogg files) - same for all of them. I recompiled it myself from Mattew's source with vce - same results. It does recognize the old plugin when

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

Hi. Here are my patches and makefiles for compiling ogg, vorbis and vorbis-tools on DOS with DJGPP. They can build them from cvs snapshots and need minimal maintainance (even extract source lists from `makefile.am's). Everything seems to work, except one FP exception on encode at middle bitrates (lowest two and highest bitrates don't cause it) - I don't think it's my

After reading http://mp3.radified.com/mp3.htm I sent Rad an explanation of some things as I understand them. He liked it and posted it on his site (still unlinked, use the URL below). Can somebody with better understanding of psycho-acoustic terms and the vorbis model check it and comment on it? In particular I didn't know how vorbis handles quantization noise. If you reply with

I agree - we should use only hex or octal, but not mixed. Cheers, Silvia.

Here's the problem: [ben at kepler tmp]# file -i presentation.ppt presentation.ppt: application/msword I see lots of references to this problem, (EG: IMP, PHP bug, etc) all of which conclude, in various forms, "the problem is in your /usr/share/magic.mime, go away". But nowhere (that I've been able to find) is there actually a solution - and even the magic.mime file from

Does the spec allow a stream consisting only of headers, with 0 audio packates? -- Beni Cherniavsky <cben@tx.technion.ac.il> (also scben@t2 in Technion) MSVC in default mode doesn't define __STDC__ (correctly!).

Not vorbis-related, just I think I found a similar technique being used... The description of the MPEG-2/SVCD plugin on the nero site says that it can encode exacty to the size of the CD (to maximize quality given a size restriction). It also says (in a separate point) that it uses two-pass VBR compression. >From that I guess they do something like encoding a bigger-than needed file and then

Monty, could you please modify the archiving mechanism so that the current month messages are archived from the begining into the month-number directory where they will be afterwards? The current scheme makes people link to this month's articles with a URL that breaks afterwards. At least please provide a symbolic link or something from the directory that will later become correct (e.g.

Just found this one: http://camelot.kingarthur.com/phoco/ogg_vorbis/info.html It seems to have music dedicated to vorbis (by the names, don't have player here) and a link to an interview with Monty ("more information on the Ogg Vorbis format") and the artists seem very excited about it. The browser says the pages are quite old (Jul./Sep. 2001) but I don't remember it being

In advanced tag editting mode, the list of tags doesn't display unicode content of tags properly.

Jonathan added to the proposal the following definition: ARTIST for information to be displayed on systems with limited display capabilities. it is not a replacement for the ENSEMBLE and PERFORMER tags, but typically will summarize them. As I understand the aim is to provide more compatibility with players (especially portable) that are so dumb as to display only "ARTIST",
