Now I am not so sure this has anything to do with the audio packets
(although that may be a problem too).

What I am seeing in another file is, for example:

first set of pages decodes to 5 frames (last granulepos is 1,5)

- decoding in sequence without returning anything results in 5 packets being
decoded - good

- decoding in sequence, returning a frame each time and then re-entering the
plugin to get the next frame results in only 3 packets being decoded

I don't understand this at all, because after returning the processing
continues where it left off, with ogg_stream_packetout(), using the same
stream data...
