Yes. Vorbis is a lapped-block codec, so each packet depends on the  
previous one. Also iirc the reference encoder has a three block  
latency for analysis. So you need to encode more than ~10 blocks in a  
row to get reasonable output.

A lot of games do playback of short vorbis-compressed sounds and  
loops. There's a "crosslapped" api entry for mixing across the  
boundaries. If that helps at all...
