just for the record -- I think you mean video/theora when you mention vorbis+VP3. Vp3 is becoming Theora. Tarkin is another video codec project at Xiph. As for this whole MIME type issue, can someone enlighten me as to how this problem is addressed with Quicktime, Microsoft, and RealNetworks plug-ins today? Also, does an MPEG4 tag specify which audio codec is used? thanks - dan

My understanding -- Monty or Emmett, feel free to chime in if you think this is incorrect -- is as follows: www.theora.org is the home for all new releases of the Theora video codec (formally known as VP3). This includes the main OGG/Vorbis integration product, which Monty is working on personally, as well as the QT and Windows codecs, both legacy VP3 versions and new versions reflecting any

[standard disclaimer about my mail format] in ftp.vp3.com/theora user: vp3 pass: vp3dev theora_dbm_5-28.zip this implements a bitstream change; the header now contains a compressed huffman tree rather than the frequency counts (as discussed) pardon my inability to use diff correctly. The change in toplevel.c is trivial (new function names & params) huffman.c is the important one. I

Thanks, Dan, for understanding what I meant with that sentence and clarifying it. I was indeed thinking of "video/theora" as MIME type to signify a theora & vorbis a/v-stream. If "Theora" is not the right name for this integrated stream, please come up with another one that is readable - I strongly dislike "oggvth". Silvia. -----Original Message----- From: Dan

./configure: line 524: syntax error near unexpected token `AM_INIT_AUTOMAKE(libtheora,0.0)' ./configure: line 524: `AM_INIT_AUTOMAKE(libtheora,0.0)' I'm sure I'm doing something pro-stupid, but --- my setup works fine for ogg & vorbis. autoconf ver 2.13 automake (GNU automake) 1.4-p4 if that matters hey let's put tool version numbers into the README -dan

good question. I would think beta means the bitstream is more or less stable. Monty? >If June is the goal for public release, is the second milestone the first beta/rc1? Guess what I'm asking is, whats a good estimate for when the codec will be frozen as far as backwards compatability.. -----Original Message----- From: Arc [mailto:arc@indymedia.org] Sent:

Here's a question I have: My understanding is that OGG is a 'containter' format, allowing for multiple streams of multiple types, of which Vorbis is only one. My question is this: Is it feasable (and, considering licencing, leagal) to create an .ogg file that contains, say Indeo or Cinepak video? (In other words, use the ogg bitstream to store the data rather than .avi).

some of you may find this helpful: I've uploaded a short (5 second) raw clip in yuv4mpeg format, associated audio, and batch files to exercise the encoder & decoder examples. In addition I've included the file as compressed (test.ogg), and a longer version as well to test playback sync. Notes: to use MPlayer with the -vo yuv4mpeg option, you need to get the latest release and compile

Good day, FYI, I've just sent the attached email to IETF to progress our I-Ds. There are also links to updated documents in this email.

A new mailing list has been created -- theora-codecs@xiph.org. This list should be where we discuss issues pertaining to Qucktime and Windows codec implementations, including legacy VP3 codecs for those platforms. We've done this to keep the discussions discrete and focused. There is a pressing need to maintain the existing VP3 codecs until we get Theora up and running. Anyone who is

Dear David, I hope it's ok to forward your email to the developer lists. I have not seen a comprehensive scheme for MIME type naming and file extensions for ogg files yet - please anybody put me in the picture if there is. However, I have seen application/x-ogg used for ogg-vorbis files, which is according to MIME type registration rules an unregistered and experimental MIME type (see

So, release priorities. I have all of derf's proposed bitstream changes accounted for in the reference encoder, if not supported in the decoder. These are going to be released as alpha 3 to get the new bitstream changes out for wider testing while we work on spec and implementations of the extensions. The remaining issue is the broken buffering in splayer. I'll take care of that

Hello everybody, I hope to finish this MIME types discussion with these conclusions - it's taken enough bandwidth on these lists :). So here's a generic MIME types scheme that we all seem to be able to agree on and all that is needed for the moment. --- 1) Ogg encapsulated files: Any data that is encapsulated in an Ogg container will us the MIME type: application/ogg (as already
