There's no current plan or ideas for an 'Ogg2'. There _is_ a libogg2,
but that's simply an alternative implementation for the existing ogg
format. Either way, libogg or libogg2, that's just a low-level set of
operations on the ogg bitstream. It includes nothing to do with
higher-level processing, that's not the intent of the library.
We've been talking at FOMS (in Sydney) about which of the existing
subtitle formats we'd like to adopt for xiph use - we don't want
people to use all the 40 or so different formats that are out there!
If you have concrete suggestions on subtitle formats, please let us
know - advice from people who are actively trying to do things would
be very welcome.
