non-decreasing granulepos
...it first and then get back to the discussion of Kate's granulepos ... Here is what some documents have to say: * Neither RFC3533 or http://www.xiph.org/ogg/doc/framing.html clarify this. * The seeking algorithm suggested in the (troublesome) email quoted at http://wiki.xiph.org/index.php/GranulePosAndSeeking is "find the earliest page with a granulepos less than but closest to 'x'" should be able to handle equal granulepos (if the earliest of a sequence of pages with equal granulepos is taken to be the first of those in the stream). * The draft mapping for Ogg Dirac uses successive...

Questions about encoder parameters.
I have almost finished integration of Theora into our videoconferencing program. Since a videoconferencing program is realtime, it is UDP-based and wraps the Theora stream in RTP (More on that later). The problem here is that most examples I could find, wraps the theora stream in ogg, and used over tcp or files. I send over UDP and clients need to be able to start in the middle of the stream.

Exact audio position
Hello! I need to extract audio data at a certain position in respect to the original audio data. Is the "-cbr" switch meant to ensure that data can be found on a specific position? I want to be able to predict where certain audio can be found in the encoded data. An example: If you put 10 apples into a box and then compress the box, you will not be able to predict where apple C

oggz reading & seeking
??????? I've rewritten my theora player using liboggz. I've stumbled upon a few issues though. First of all liboggz exposes oggz_read and oggz_run, but how can i read only sound data, or only video data using liboggz, say something like this: oggz_read_sound(1024), oggz_read_video(1024). ? ? ? ?? Second of all i tried using liboggz's seek function. Immediately after the seek i get some

Seeking to granules in discontinuous streams
...dy corrected that statement then - the wiki seems the right place to put the correct algorithm, IMHO. Cheers, Silvia.
