Hi! I'm not a developer but it takes one to answer my questions. I was just thinking about how the command line encoder could work in the end (after having played with encoder_example) Some ideas: 1. There could be the option of having a -q switch (just like oggenc) controlling BOTH audio and video so that for each level of q the sum of video and audio bitrates could be known (sort of

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

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

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

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

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

Hello, I was wondering about the lowpass filter applied at the different quality levels. It seems that the 16kHz cut-off is still there at quality 3. I didn't really abx it, so maybe my mind plays tricks on me. :) Please can someone enlighten me what is used for -q0, -q1 and so on. (lame tells me whats used when encoding tracks) I know I shouldn't judge by bandwidth but I would like to

i am SURE this is really simple.. and i am SURE i have read this a million times.. but i am not wiring this up in my brain correctly.. if i have a parent class that has fields: Podcasts id title description and a child class like: Episodes id podcast_id title description filename i can get the episode information all day.. but using the "Episode" class, can i access the

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

Hello Odin, Thank you very much for your interest and your advice! Yes I know Monty and Jean-Marc great demo pages.So a technology demo seems definitely interesting.As you say, a good explanation of how the codec works one exciting thing at a time seems to be a good formula.I will try to take inspiration from Monty and Jean-Marc pages.What I will certainly lack is a good graphical design for
