I suggest using the solution that CMML has come to use. The XML file is essentially the same as an unencapsulated physical bitstream. Then there is a mapping into a logical bitstream, where some of the default information - in particular the XML header - are split off and put into the bos packet - nothing really needs to go into the eos packet. There's also a magic number and a version

Hi Ian, CMML is still a draft, so we can change the addressing if required. You're correct, currently something like blah.cmml#fragment points to a clip (or temporal section) of the stream, but blah.cmml#t=12 points to a 12 seconds offset. (same for annodex, i.e. ogg files with skeleton track). For pointing to logical streams inside ogg, I'd really suggest you have a look at

So wiki discussion on the new metadata format is ongoing. I'd like to move some things about a bit. MDMF is a discussion of the metadata XML format itself, Metadata gives some background an overview and a few old sample cases. I'm not sure how many people read the wiki talk page so I thought I'd ask here if there were any objections before doing it. What would most likely happen

Hi All, I'm relatively new to Ogg and Vorbis and I've hit a pretty puzzling issue, and I'm wondering if a veteran could help me out. I'm attempting to decode a chained live Ogg Vorbis stream. The primary issue is that the source does not exactly follow validation (I have no control of this). The stream switches from a prerecorded segment, to a live segment, back to a prerecorded

Hi, I was wondering what oggz_get_bos and oggz_get_eos are supposed to do, specifically are they meant to be used in oggz_read mode? The documentation says "Determine if a given logical bitstream is at [bos/eos]". However if get_bos is given a specific serialno it returns that stream's b_o_s flag which, in read mode, is set on initialisation. The serialno=-1 (for all streams)

What do you want to use OggPCM for? Why not use AU or WAV? I can only see an advantage in using OggPCM if you want it annotated using CMML or want to mix it with another codec, such as Theora.

I've googled, RTFMed, and I still can't fix this. Hoping someone here can offer a suggestion. I'm learning, so please explain a little if you can. I installed samba on a Ubuntu 5.10 machine (named mog). My XP machine "sees" it, but the username/password dialog fails. I've traced it down to what I think is an authentication problem: mat@mog:/etc/samba$ smbclient -L

What I've gotten out of this discussion so far: 1) we need to introduce a means in which to do captions; this could be done through adding a "caption" element to CMML, or in another time-continuous annotation format; so far I am not sure which would be the better way 2) we need a XML annotation format for audio - in particular for music - that is more structured than vorbiscomment

Hi all, I am trying to set up the codecs table in the wiki and we have played a bit with Dirac to find out what existing tools write into the header. The Schroedinger implementation by Fluendo uses (or used to use) "KW-DIRAC" as the identifier in the Ogg header. "BBCD" is the identifier of each of the Dirac data packages. More recently, I read that the Dirac Sequence header

The biggest problem with Vorbis comments are too loose specifications and too little standardisation. Another problem is attribution of involved parties. Currently only the ARTIST field name is supported in software. More standardised field names need to be worked out for organisations and persons involved in the production of the recording. See:

so becky said mog is out, i remeber seeing it about a year ago on craigslist but didnt apply since it sounded like a last.fm ripoff and why waste time reinventing a wheel?..anyways, im wondering if it performs ok for anyone? it keeps freezing up on my trying to edit the page. sometimes a response comes back after about 10 seconds. im only guessing it runs rails, based on the gratuitous use of

Hi. I would like to partially apply a function to a list of arguments, and I don't know how to do this in R, without perhaps writing default values to the formals() of my function, or writing to the environment object of a function. For context, my definition of partially apply is: "fix some of the arguments, leaving the others as variables, return a new function that takes the un-fixed

I have made a patch to support libvorbis to allow parsing a vorbis bitstream in an ogg bitstream containing additional bitstreams. The patch is attached in the given ticket http://trac.xiph.org/ticket/925#preview from my experiment it successfully decodes a normal vorbis file and a vorbis+skeleton+cmml file. thanks in advance for reviewing it. -------------- next part -------------- An HTML

Hi there, I'm not sure what the right place would be, please direct me to where is most appropriate if not this list. I am currently working on a codec designed for karaoke and text information, to be embedded in an Ogg container. It includes text, motion information, and style/placement. At the moment, the bitstream design is still in flux, but draws heavily from Vorbis and Theora, while
