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

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

At this point, my understanding is as follows. Monty has the final word but I believe this is his intention: * Theora is a video codec. It is a modification of VP3. Presently it is assumed that Theora will be a superset of VP3; ie, VP3 streams can, with a little header magic, be losslessly transcoded into Theora streams. However, we expect future versions of Theora to diverge significantly

For the past few years, users of the QuickTime container have faced a similar dilemma to what we have

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.

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

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

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
