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

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

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

Hi, I'm probably being fairly stupid. But I did the following, starting with the following two files: # tcprobe -i vts_01.m2v [tcprobe] MPEG elementary stream (ES) [tcprobe] summary for vts_01.m2v, (*) = not default, 0 = not detected import frame size: -g 720x576 [720x576] aspect ratio: 16:9 (*) frame rate: -f 25.000 [25.000] frc=3 # tcprobe -i vts_01.m2a

Hi, just to prevent me from overreading something, I have a question and probably the only possible solution, but I would appreciate if someone could tell me if there is a better solution. I am currently implementing an Ogg demultiplexer for a media API, where the demultiplexer plugin has to provide a static number of logical streams. Adding and removing logical streams as they appear when

The IETF passed the application/ogg MIME type some days ago. I couldn't bring you the news earlier because of the MS SQL worm that has been wreaking havoc all over my local networks. The IETF wants some clarifications in Silivias draft for the Ogg stream format, but apart from that I think it will also be passed soon. The RFC and IANA registration of this mimetype will probably be published

Please allow me to emphasize it again, for clarity, avoiding the reiterated confusion to some readers / users.

Suddenly, quite a few people have jumped in and started active experementation and discussion about Tarkin, as well as playing with the very rudimentary test-of-concept 3d wavelet coder jack, hatamoto and I hacked on last year. For your use, I've added a new mailing list, tarkin-dev@xiph.org, for discussion and hacking on Tarkin. The list is run, linked and archived at xiph.org like the

Me again, this time not about patents but about wavelets. I've been doing some work on an image compression method which uses Haar wavelets plus VQ and entropy coding, and Segher Boessenkool told me in a private message that you are also doing a video codec. So I searched the archives and read a bunch of posts, but I never did find out any web address. And it's not on xiph.org either. So
