I was being a little flip. It's more like alpha testing. libthera has
been ported to libogg2 (at least as it stood a couple of years ago),
just compile with -DLIBOGG2. However, libvorbis needs porting if you
want to use it as well.
There are iirc two code bases. Monty's original:
and a branch developed by Arc Riley:
Well, three, really. The Tremor fixed-point vorbis decoder
implementation includes another version internally.
So if you want to download and build one of both of those and
try to get theora and your application working with it, we
could definitely use some feedback on the design. However, it's
not necessarily the fastest way to finishing your application.
libogg1 is quite mature at this point.
There hasn't been active work on libogg2 in over a year, but Monty
has been making noises about picking up development again.
I believe the major goals were, not necessarily in order:
1. clean up memory ownership and other API glitches
2. provide zero-copy page and packet access to reduce
memory footprint and bandwidth for embedded applications
3. provide dovetailed support for monty's idea for a multimedia
Maybe someone else can comment if I'm missed (or misstated) something.
