Hi

<p>When will there be another Alpha/Beta/Release of Theora?
Is there anywhere a timeline?
As I can remember there should have been a new beta before 5-6 month, but there wasn't any! - Why?

Is there perhaps another OpenSource-Projekt which includes the vp31 source and can encode/decode
vp3? (I know ffmpeg is working on a decoder)

<p>Jens

<p><p>> ugh.  I can't recall exactly, but I'm pretty sure there were major changes to the token scheme.  THey're definitely incompatible bitstreams.  The production decoder had a switch -- I guess we took it out when we went open-source.  What DLL plays these files?  Can you re-encode them?
