Actually, we have been discussing this kind of addressing for a very long time and it was half the point of the Annodex project (see www.annodex.net). What we have defined for addressing is the following: * temporal addressing: http://annodex.net/TR/draft-pfeiffer-temporal-fragments-03.txt Any ogg file can be addresses through temporal offsets. This goes across different logical bitstreams. *

Hi, The Annodex Foundation is pleased to announce the general availability of the Annodex Media Validation Service, a free service that checks Web-accessible Ogg, CMML and Annodex media resources for conformance to Annodex and Xiph.Org specifications: http://validator.annodex.org/ Details about the operation of this service are available at: http://validator.annodex.org/about.html

While this is possible to do it this way (and probably a good idea for the examples like a clock in a corner), it implies that all the placements and logically different "items" are known at the start of the stream (since the Ogg spec says a

Hi, I recognize the main name behind CMML here :) Does the redesigning of CMML allow overlapping clips ? This is the main reason of my current ramblings about seeking. While karaoke was one of the initial goals behind kate, it is just a way the format can be used with (in fact, the format itself does not refer to karaoke at all, but styles and motions). At the moment, it is a fairly versatile

In one of the last monthly meetings it was decided that OggPCM is ready and all it needs is an implementation (for instance, in ogg123). The problem is that nobody seems available to do it. If either Martin or Sampo would like to work on it, I believe nobody will oppose. CMML and Skeleton implementations are far more urgent right now, though. I have changed the main page in the XiphWiki to

HOgg 0.4.1 Released ------------------- The HOgg package provides a commandline tool for manipulating Ogg files, and a corresponding Haskell library. HOgg is in hackage, or on the web at: http://www.kfish.org/~conrad/software/hogg/ This is the fourth public release. The focus is on correctness of Ogg parsing, production and editing. The capabilities of the hogg commandline tool are roughly on

Well, actually most OGM files do have a subtitle track, often in multiple langauges. Also, re 2. Keyframe seeking in OGM is generally a bit rough because ogm files can contain almost any codec as the video track, usually xvid or divx. re 1. As a general rule you shouldn't be trying to make any more ogm files :) So chances are the ogg muxer is not accepting the connection, because it

Daniel, these are all good ideas and worth progressing. However, it may be better not to merge too many goals in one format (MPEG-7 did that and ended up as a big mess). So, I suggest to start by structuring the types of things you want - then finding out which parts belong where into existing formats such as vorbis comment, Skeleton and CMML, and only then start to develop a new format.
